A fern is a member of a group of VASCULAR plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from MOSSES by being vascular, i.e., having specialized tissues that conduct water and NUTRIENTS and in having life cycles in which the sporophyte is the dominant phase. Ferns have complex LEAVES called megaphylls, that are more complex than the MICROPHYLLS of clubmosses. Most ferns are leptosporangiate ferns, sometimes referred to as true ferns. They produce coiled fiddleheads that uncoil and expand into fronds.[3] The group includes about 10,560 known extant species.[4]

it is the MODERN METHOD of irrigation. This method is very use ful for areas having acute water shortage Explanation: in this methods water falls DROP by drop NEAR the roots through narrow PIPES and tubes. Hence there is no wastage of water in this method

microorganisms help in performing different BODY functions then they also take SOMETHING from the body that is they take nutrients from the body. One PURPOSE of bacteria in the body is to FIGHT against those harmful bacteria which can cause diseases.....

Hey friend!___________Here is your answer______________________There are mainly two ways by which crop production can be increased:⇒ MULTIPLE cropping: Multiple cropping is the method where more than one kind of crop is grown in a single season on a given season of land. In Palampur, Farmers first grow Kharif crops such as BAJRA and Jowar and later they grow potato. Then they grow rabi crops such as wheat. Sometimes they also grow jaggery.⇒ Modern farming methods: The green REVOLUTION has brought many changes in the farming system. High yielding VARIETIES ( HYVs ) seeds, MADE sure that more grain was present on a single crop. This also increased the used of tractors, fertlizers, pesticides and Harvesters._____________________________________________________________HOPE THIS HELPS YOU :)

Our objective is to identify the different parts of an embryo of dicot seeds- pea, gram and bean.TheoryA seed is a small embryonic plant ENCLOSED inside a seed coat. It is the ripened and fertilised ovule of gymnospermic and angiospermic plants. A seed has a three parts:An embryoA supply of nutrients for the embryoA seed coatThe embryo is an undeveloped plant inside a seed from which a new plant develops. All seeds do not have the same SIZE, shape and colour. We will be looking at the embryo of a pea, gram and bean seed to identify their different parts.Plant EmbryoPlant embryos in seeds have structures called cotyledons. A cotyledon is the central portion of a seed embryo to which the epicotyls- the immature shoot, and the RADICLE- the immature roots, are attached.Plants are classified according to the number of cotyledons present in the embryo. If the embryo has one cotyledon (monocotyledon) it is a monocot plant, and if there are two cotyledons (dicotyledon), it is a dicot plant.Seed SubdivisionBased on the type and location of storage materials, seeds can be subdivided into endosperms and non endosperms.Endospermic SeedsEndospermic seeds are those that have an endosperm in the mature seed. It is fleshy, oily, surrounds the embryo, and functions as the sole FOOD storage organ. Inside the seed coat, a thin and papery cotyledon is present. Monocot plants have endospermic seeds.Non-endospermic SeedsNon-endospermic seeds do not have an endosperm in the mature seed. The cotyledons are thick and fleshy, and function as the sole food storage organs. Dicot plants have non-endospermic seeds. Seed GerminationGermination is the process in which the seed breaks apart, and the embryo inside begins to grow with the help of water and nutrients from the soil. Seeds normally begin to germinate when they get an appropriate range of soil, temperature and when water and oxygen are available. During germination the seeds absorb water either through the micropyle (pore like opening), if it is present, or through the testa (outer seed coat) when it is permeable. The entry of water activates the embryo cells.Germination in a Dicot Seed (Pea, Gram and Bean)The pea, gram and bean seeds have two seed coats that envelope and protect the embryo. The outer seed coat called the testa is thick and strong. The inner coat is called tegmen, which is thin and membranous.The outer seed coat has a notch on one side and a scar along the notch, called the hilum. It is the hilum that attaches the seed to the inner margin or the seed stalk. There is a small pore called micropyle located at one end of the hilum. The seed imbibes water through the microphyle.Once soaked for the required time, the part of the plant that FIRST emerges from the seed is the embryonic root known as the radicle. The radicle allows the seedling to anchor itself to the ground and start absorbing water.After the root starts absorbing water, an embryonic shoot emerges from the seed. This shoot comprises of three main parts- the cotyledons (seed leaves), the hypocotyl (section of shoot below the cotyledons), and the epicotyl (section of shoot above the cotyledons).

Grafting is a HORTICULTURE technique where tissuses of plants are joined so as to continue their GROWTH together. The upper part of the combined PLANT is called the scion while the LOWER part is called the rootstock.And the best season for grafting is spring.Hope this will help uh  ☺️❣️

E coli takes up nutrition and shelter from our INTESTINE, in return GIVES us different varieties of vitamin ( Vitamin B12

in a CLOUDY day but in BRIGHT sunlight, PHOTOSYNTHESIS will remain normal and same.in AREAS of less RAINFALL, it is going to be decresed.gathering of dust will not affect photosynthesis.

HOW TO PROPAGATE PLANTS FROM CUTTINGSCut a 4- to 5-inch-long (10 to 12 cm) STEM (or side shoot) just below a leaf, and REMOVE all but two or THREE leaves at the top. ...Dip the cut end into rooting hormone. ...Insert the cutting into a box or container, FILLED with about 3 inches (8 cm) of moistened pure builder's sand, vermiculite, or perlite.

tion: I Think Your Question Is What Is Striated Epithelium Tissue!!!!A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only ONE layer is in contact with the basement membrane; the other layers adhere to one another to maintain STRUCTURAL integrity.Examine the simple striated COLUMNAR epithelial lining at this higher magnification. ... The epithelium consists of a single layer of columnar cells resting on an undetectable basement membrane. The cells are tightly packed, forming a CONTINUOUS sheet of cells that effectively forms the protective lining of the stomach.It is found in Epithelium lines both the outside (skin) and the inside cavities and lumina of bodies. The outermost layer of human skin is composed of DEAD stratified squamous, keratinized epithelial cells.

tion:Coelom is a fluid FILLED space between the body WALL and gut wall and lined by mesoderm on all of its sides. The presence or ABSENCE of body cavity or coelom plays a very important role in the classification of animals. Animals that possess a fluid filled cavity between body wall and digestive TRACT are known as coelomates. Annelids, mollusks, arthropods, echinodermates, and chordates are EXAMPLES of coelomates. On the other hand, the animals in which the body cavity is not lined by mesoderm are known as pseudocoelomates. In such animals, mesoderm is scattered in between ectoderm and endoderm. Aschelminthes is an example of pseudocoelomates. In certain animals, the body cavity is absent. They are known as acoelomates. An example of acoelomates is platyhelminthes.

tion:The phylum ARTHROPODA consists of more than 75% of the animal species found on this earth. The reasons for the SUCCESS of arthropods are as follows.i. JOINTED legs that allow more mobility on LANDII. Hard exoskeleton made of chitin that protects the bodyiii. The hard exoskeleton also reduces water loss from the body of arthropods making them more adapted to TERRESTRIAL conditions.

tion:the LOSS of biodiversity can be prevented :- Attract “good” insects by planting pollen and nectar plants. Maintain WETLANDS by conserving water and REDUCING irrigation.
