Answer:

cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of STRUCTURE in all organisms and ALSO the basic unit of reproduction. With continual IMPROVEMENTS made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many DEBATES about cells began amongst scientists. Most of these debates INVOLVED the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchow contributed to the theory. It was an important step in the movement away from spontaneous generation.

Explanation:

Ingestion: is the process of taking food in to the body or ‘eating of food’ by the animal. When we put food in to our MOUTH with hands, we are ingesting it.

Digestion: is the process in which the food containing large, insoluble molecules is broken down in to small, water soluble molecules which can be absorbed by the body or digestion is the dissolving of the solid food. Most of the animals include both physical and chemical methods for digesting the food. Physical method includes chewing and grinding the food in mouth and chemical method include the addition of digestive juices (enzymes) to food by the body itself.

Absorption: is the process in which the digested food passes through the intestinal wall in to blood stream. As, after the digestion, food molecules become small and soluble. This food passes through the WALLS of our intestine and goes in to the blood.

Assimilation: is the process in which the absorbed food is taken in by the body cells and used for energy, growth and repair. Blood carries the absorbed food to all the PARTS of the body.

Egestion: is the process in which the undigested food is removed from the body. The whole food which we eat is not digested by our body, a part of the food remains undigested which cannot be used by the body and so it is removed from the body in the form of faeces when we go to the TOILET.

ANSWER:

this is megasporogenesis. Ovules generally differentiate a single MMC in the MICROPYLAR region of the nucellus. It undergoes meiosis and produces 4 MEGASPORES.

Answer:

The xylem and the phloem MAKE up the vascular tissue of a plant and transports water, sugars, and other important SUBSTANCES around a plant. What is commonly referred to as ‘SAP’ is indeed the substances that are being transported around a plant by its xylem and phloem.

The SEPARATION between plants that have veins and plants that do not is one of the great divides within the plant KINGDOM. This separates plants into vascular and non-vascular plants. Most plants have xylem and phloem and are known as vascular plants but some more simple plants, such as mosses and algae, do not have xylem or phloem and are known as non-vascular plants.

Answer:

The key difference between simple and complex tissue is, simple tissue is made up of only one type or kind of cell whereas complex tissue is made up of different type of cells. A simple tissue in ANIMALS is termed epithelium whereas epidermis in plants. Example muscle tissue. Complex tissues are scattered everywhere in the body to bind organs and support them. A complex tissue in animals is termed as connectivity tissue whereas vascular tissue in plants. Example blood tissue. Below are some other differences between the two tissues.

Difference Between Simple And Complex Tissue

Characteristics Simple tissue Complex tissue

Type Homogeneous Heterogeneous

Distribution Wide Restricted

Performance Many functions Majorly TAKE part in conduction

Made of A single type of cell More than one type of cells

Function Food storage To protect

Occur All parts of a plant The vascular region of a plant

Provides Transportation of water and food in plants Support to plants

Example COLLENCHYMA, parenchyma Phloem, Xylem

hi friend

here is your answer

Answer:

Mucilage is a thick, gluey substance produced by nearly all plants and some microorganisms. These microorganisms include protists which use it for their locomotion. The direction of their movement is always opposite to that of the secretion of mucilage.[1] It is a POLAR glycoprotein and an exopolysaccharide. Mucilage in plants plays a role in the storage of water and food, seed germination, and thickening membranes. Cacti (and other succulents) and flax SEEDS are especially rich sources of mucilage

Occurrence

Exopolysaccharides are the most stabilising factor for microaggregates and are widely distributed in soils. Therefore, exopolysaccharide-producing "soil algae" play a vital role in the ecology of the world's soils. The substance covers the outside of, for example, unicellular or filamentous green algae and cyanobacteria. Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life cycle. It occurs in almost all plants, but usually in small amounts. It is frequently associated with substances like tannins and alkaloids

Mucilage has a unique purpose in some carnivorous plants. The plant genera Drosera (sundews), Pinguicula, and others have leaves studded with mucilage-secreting glands, and use a "flypaper trap" to CAPTURE insects.

Human uses

Glass container for mucilage, from the first half of the 20th century.

Mucilage is edible. It is used in medicine as it relieves irritation of mucous membranes by forming a protective film. Traditionally, marshmallows were made from the extract of the mucilaginous root of the marshmallow plant (Althaea officinalis) as a cough medicine. The inner bark of the slippery elm (Ulmus rubra), a North American tree species, has long been used as a demulcent and is STILL produced commercially for that purpose.

Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps.Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to METAL cans, wood to china, and leather to pasteboardDuring the fermentation of nattō soybeans, extracellular enzymes produced by the bacterium Bacillus natto react with soybean sugars to produce mucilage. The amount and viscosity of the mucilage are important nattō characteristics, contributing to nattō's unique taste and smell.

The mucilage of two kinds of insectivorous plants, sundew (Drosera)[8] and butterwort (Pinguicula),is used for the traditional production of a variant of the yoghurt-like Swedish dairy product called filmjölk

Ecological implications for plants

The presence of mucilage in seeds affects important ecological processes in some plant species, such as tolerance of water stress, competition via allelopathy, or facilitation of germination through attachment to soil particles. Some authors have also suggested a role of seed mucilage in protecting DNA material from irradiation damage.[15] The amount of mucilage produced per seed has been shown to vary across the distribution range of a species, in relation with local environmental conditions of the populations.

Answer:

Explanation:

Double Circulation

A circulatory path is a path taken by the blood, wherein it travels throughout the different organs of the body through arteries and veins. In humans, it is a closed circulatory system that EXISTS, as blood flows in closed blood vessels. The circulatory system is responsible for the transport of gases, nutrients, waste products etc.

Mechanism Of Double Circulation

Double circulation is the most efficient way of circulation. Here, in humans, the four-chambered heart, arteries, veins, and capillaries all have a vital role to play. Blood gets pumped out of the heart. This blood goes to different organs and then blood again comes back to the heart. All this happens in a very systematic way through the different arteries and veins carrying oxygenated and deoxygenated blood.

In double circulation, there are two PATHWAYS in which blood flows. They are:

• Pulmonary pathway
• Systemic pathway.

The pulmonary circulation or pathway carries the deoxygenated blood from the right side of the heart to the lungs.  Exchange of OXYGEN and carbon dioxide takes place in the lungs and the blood is now oxygenated (with oxygen).

Through the systemic circulation, oxygenated blood travels from the left side of the heart to the other areas of the body. At various organ sites, exchange of gases, nutrients, and waste through lymph occurs. This deoxygenated blood again goes back to the right side of the heart.

The pulmonary circuit and the systemic circuit work together. This ensures that deoxygenated blood goes to the lungs through the pulmonary artery while the oxygenated blood from the aorta reaches the different organs and tissues.

Capillary exchange

The arteries and veins have an extensive network throughout the body carrying oxygenated blood and deoxygenated blood.  The smallest of these arteries and veins are connected each other through the capillaries.

The capillaries at the arterial end ALLOW materials such as water, glucose, oxygen, and amino acids to diffuse out. Capillaries also transport wastes and carbon dioxide to organs which can dispose of them. And so, the waste products ENTER near the venous ends of the capillaries. To maintain the blood volume, water diffuses in and out of capillaries.

Through the process of capillary exchange, oxygen leaves RBCs in the bloodstream and enters all the other cells of the body. Nutrients also diffuse out of the bloodstream into other cells. Simultaneously, the other cells expel the waste products which enter the capillaries. Carbon dioxide also diffuses out of the cells and enters into the capillaries, at the venous end.

These venous ends of the capillaries are connected with the smaller veins and venules, which join the larger veins. These veins now have deoxygenated blood. Through the main vein called as vena cava, blood enters the right atrium chamber of the heart, from where pulmonary circulation starts.

Explanation:

Urine is FORMED in the kidneys through a filtration of blood. The urine is then passed through the URETERS to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body. ... This amount varies according to fluid intake and kidney FUNCTION.
