Why is Rhizobium called symbiotic bacteria , and what is it's role and importance |
|
Answer» Legumes are ABLE to form a symbiotic relationship with nitrogen-fixing SOIL bacteria called rhizobia. The result of this symbiosis is to form nodules on the PLANT root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant. Rhizobium–legume symbioses are of great ecological and agronomic importance, due to their ABILITY to fix LARGE amounts of atmospheric nitrogen. These symbioses result in the formation on legume roots of differentiated organs called nodules, in which the bacteria reduce nitrogen into ammonia used by the host plant. |

How the local farmer grow rabi & kharif crops notes for kids? |
|
Answer» Answer: Kharif crops, monsoon crops or autumn crops are domesticated plants like rice that are CULTIVATED and harvested in India, Pakistan and Bangladesh during the Indian subcontinent's monsoon season, which lasts from June to November depending on the area.[1] Moonsoon rains may begin as early as May in some parts of the Indian subcontinent, and crops are generally harvested from SEPTEMBER to October, again depending upon the region and the crops. Rice, maize and cotton are major kharif crops in India. Rabi crops or rabi harvest are agricultural crops that are sown in winter and harvested in the spring in India.[1] The term is derived from the Arabic word for "spring", which is USED in the Indian subcontinent, where it is the spring harvest (also known as the "winter CROP").The opposite of rabi crops are the kharif crops which are grown after, the rabi and zaid crops are harvested one after another RESPECTIVELY... follow meeeeee.... mark me as Brainliest.... |

Related cell organelles and their functions with different working bodies o |
|
Answer» Answer:Cell Organelle A small organ-like structure present inside the cell is called a cell organelle. It has a particular structural makeup and performs a specific function. Depending upon the presence or absence of membrane, cell organelles can be classified into three categories, namely: Without membrane: Some cell organelles like ribosomes are not bounded by any membrane. They are present in prokaryotic as well as eukaryotic organisms. Single membrane-bound: Some organelles are bounded by a single membrane. For example, vacuole, lysosome, Golgi Apparatus, Endoplasmic Reticulum etc. They are present only in a eukaryotic cell. Double membrane-bound: Cell organelles like mitochondria and chloroplast are double membrane-bound organelles. They are present only in a eukaryotic cell. Explanation:Structure and FUNCTIONS of Cells Structure and functions of different cell inclusions are as follows-
Cell Organelle Occurrence/ Characteristic & Structure Function Cell Membrane/ Plasma Membrane Present in both plant cell and animal cell. Selectively Permeable: Allows the materials in and out of the cell according to the requirement of the cell. Made up of bilipid layer and protein (Fluid Mosaic Model) Encloses the contents of the cell. Provides shape: animal cell. Allows transport: by Diffusion and Osmosis. Cell Wall Present only in a plant cell. Hard and rigid. Fully permeable. Made up of Cellulose in plant and peptidoglycan in bacteria. Protection Gives shape and turgidity. Cytoplasm Contains 80-90% water and many organic and inorganic compounds. Colloidal, Viscous, Jelly like fluid inside the cell. Contains ENZYMES responsible for all the metabolic activity taking place inside the cell. Nucleus (Director/ Brain of the Cell)
Covered by a double MEMBRANOUS nuclear membrane in a Eukaryotic Cell. Contains DNA, RNA, Protein, nucleolus, and Chromatin network. Controls the activity of the cell. Starts cell division. It has the chromosomes or DNA which controls the hereditary characters Mitochondria (The Power House of The Cell / Storage Batteries) Double membranous structure. Autonomous body as contains its own DNA. Self-duplicates The main seat of respiration. Stores energy in the form of ATP molecules. Golgi Bodies (Shipping Department of Cell) Discovered by Camillo Golgi in 1898. Originates from RER. Contains Sac like Cisternae and Vesicles. Has two faces – cis face or receiving face and trans face or supplying face.
Modification, Packaging, and transport of materials Synthesis of lysosomes, plasma membrane Endoplasmic Reticulum (Framework of Cell) A network of membranes. RER bears ribosomes and appears rough SER does not have ribosomes Forms the skeletal framework of the cell. Transport of materials from one cell to other. Provides a surface for the synthesis of material – PROTEINS in RER and LIPIDS in SER. Formation of lysosomes, Golgi bodies and vacuoles Membrane Biogenesis Detoxification of harmful substances in the liver. Vacuole Arise from ER and GB Surrounded by tonoplast and filled with cell sap
Store cell sap which may be liquid or solid food, toxic byproduct. Provide rigidity and turgidity to plant cell
Lysosomes (Suicidal bags of Cell, natural scavenger, cellular housekeeper) Membrane-bound organelles Present in all animal cells and few plant cells Tiny circular single membrane-bound structures filled with digestive enzymes Intracellular digestion of food in unicellular organisms.
Ribosomes (Protein Factories) Without a membrane Consist of two subunits – 60S and 40S in eukaryote both made up of RNA Synthesis of Proteins Plastids Double membrane-bound Types- Leucoplast –Colourless plastid; Chromoplast –Coloured Plastid – blue, red, yellow Chloroplast – Green plastid Autonomous self-duplicating body Chloroplast – Perform Photosynthesis – Helps in the release of oxygen Chromoplast – impart colour to flowers which help in pollination Leucoplast – Storage Amyloplast –Store starch Aleuroplast – Store Protein Elaioplast – Store fat

Example for species |
|
Answer» Answer:Polar bears and Grizzlies Oftentimes the only barrier to reproduction is geographic, or based on the physical location of the animals. If this changes, the animals can interbreed, and may MERGE into one species. This is currently being SEEN in the wild in polar bears and grizzly bears. As the climate changes, polar bears are forced further south, and must start exploiting different food sources. The change in climate also allows grizzly bears to venture further north, encountering polar bears along the way. The previously separated populations now have a chance to breed, and sometimes they are successful. Hybrids have been seen in the wild, but it is not yet KNOWN if they hybrids will be successful. There are many different situations and examples of reproductive barriers, but if the barrier can be removed, it is likely that two related species will be able to interbreed. Non-related species rarely have a possibility of breeding because they have become too different from each other. For instance, a bat and turtle have a completely different genetic makeup. The genes that control growth in the turtle would not function in a bat, and vis-versa. In fact, they don’t even have the same NUMBER of chromosomes, which is a requirement for sexually reproducing organisms to be successful. Dogs and Wolves STILL other animals, like dogs and wolves, are still technically the same species. While they have the same number of chromosomes and could technically breed, the domestic dog has come a long way from its wild counterpart. Dogs have not only evolved to be more cuddly and soft, but are attuned to human social cues. Wolves operate in a much different social structure. As such, the two are very unlikely to breed in the real world. However, because they can create fertile offspring, scientists consider them the same species. Dogs and wolves are a good example of species radiation, or the incremental changing in a population that is widely distributed. Think of a Chihuahua. If Linnaeus had classified this animal, he certainly would not have put it in the same category as a wolf. However, a Chihuahua can breed with a slightly bigger dog, which can breed with large dog, which could easily breed with a wolf. In this way, a Chihuahua and a wolf have the same genetic basis, expressed in very different ways. Explanation: |

Ecological adaptations of any life form is a two way process where evolution |
|
Answer» Explanation: Living organisms are adapted to their environment. This means that the way they look, the way they behave, how they are built, or their way of life makes them suited to survive and reproduce in their habitats. For example, giraffes have very long necks so that they can eat TALL vegetation, which other animals cannot reach. The eyes of cats are like slits. That makes it possible for the cat's eyes to ADJUST to both bright light, when the slits are narrow, and to very dim light, when the slits are wide open. Behavior is also an important adaptation. Animals inherit many kinds of adaptive behavior. In southern Africa there are small animals called meerkats, which live in large colonies. The meerkats take turns standing on their hind legs, looking up at the sky to spot birds of prey. Meanwhile, the meerkats in the rest of the colony go about their LIVES. You can probably think of many other features of body or behavior that help animals to lead a successful life. In biology, an ecological niche refers to the overall role of a species in its environment. Most environments have many niches. If a niche is "empty" (no organisms are occupying it), new species are likely to evolve to occupy it. This happens by the process of natural SELECTION. By natural selection, the nature of the species gradually changes to become adapted to the niche. If a species becomes very well adapted to its environment, and if the environment does not change, species can exist for a very long time before they become extinct. An excellent example of an animal evolving to fill a niche is seen in the evolution of horses. Many fossils of different kinds of horses have been discovered, and paleontologists think that the earliest ancestor of the modern horse lived in North America more than 50 million years ago. This animal was a small padded-foot forest animal about the size of a dog. If you saw one next to a modern horse, you might not even think the two were related! As time passed, the climate of North America became drier, and the vast forests started to shrink. Grasses were evolving, and the amount grassland was increasing. Horses adapted to fill this new grassland niche. They grew taller, and their legs and feet became better adapted to sprinting in the open grasslands. Their eyes also adapted to be further back on their heads to help them to see more of the area AROUND them. Each of these adaptations helped the evolving grassland horses to avoid predators. Their teeth also changed to be better adapted to grinding tough grassland vegetation. Have you ever wondered what purpose the "dew" claw on the inside of a dog's paw serves? The claw is the dog's thumb. Because a dog runs on the balls of its feet and four digits, the claw no longer serves a purpose. Organs or parts of the body that no longer serve a function are called vestigial structures. They provide evidence that the species is still changing. Even humans have vestigial structures. The human appendix is one such example. It used to store microbes that helped to digest plant matter, but it is no longer needed in the human. I hope this may help you please follow me and mark as brainliest |
