What are three advantages seed?
i) They provide nourishment and parental care to the developing embryo, ii) They protect the embryo from harsh environmental conditions. iii) They generate new genetic combinations leading to variations. Explain any three advantages the seeds offer to angiosperms.
What are the advantages of seed formation for the plants?
Advantages of seed formation are: The seed contains the future plant or embryo which develops into a seedling. Seeds can get dispersed by wind or animals into new areas, thereby allowing the species to colonize new areas and also protects the species from becoming extinct.
What advantages a seed provide to a plant mention four advantages?
Seed formation is more dependable, better adaptive strategy for dispersal to new habitat, hard seeds provide protection to the young embryo, being a product of sexual reproduction they generate new genetic combinations/genetic variations/sufficient food reserve for the young seedling to be nourished.
What are the advantages of little seeds?
Larger seeds are better able to support themselves initially, while smaller seeds have a better chance for dispersal over a wide area, helping at least some seedlings survive.
What are the advantages of seeds Class 12?
(i) They provide nourishment and parental care to the developing embryo. (ii) They protect the embryo from harsh environmental conditions. (iii) The dispersal of seeds to far-off places prevents competition among the members of the same species, thus preventing their extinction.
What is the advantages of seed dispersal?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
What are the advantages and disadvantages of propagation by seed?
Advantages Of Propagating From Seed: Seeds are the source used most widely. New cultivars and varieties can be created through sexual propagation. It tends to be cheaper to propagate from seed. The majority of seeds are readily available. Sexual propagation seldom requires expensive propagation structures.
What are the evolutionary advantages of seeds over spores?
Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes ), seeds contain a diploid embryo that will germinate into a sporophyte. Storage tissue to sustain growth and a protective coat give seeds their superior evolutionary advantage.
What are two advantages that seed plants have over seedless plants?
Seed plants have some advantages over seedless plants. For example, when a seed begins to grow, the young plant uses the food stored in the seed. The spores of seedless plants don’t have stored food to help a new plant grow. Another advantage of seed plants is that seeds can be spread by animals.
Are seeds tasty?
Contrary to popular belief, eating seeds in their raw form is not necessarily more nutritious than eating them roasted or toasted. Besides using seeds to spruce up your salads, they make a great addition to soups, stir-fries and your morning cereal. They even taste good on ice cream.
What seeds do you eat?
6 Super Healthy Seeds You Should Eat Flaxseeds. Share on Pinterest. Chia Seeds. Chia seeds are very similar to flaxseeds because they are also good sources of fiber and omega-3 fats, along with a number of other nutrients. Hemp Seeds. Sesame Seeds. Pumpkin Seeds. Sunflower Seeds.
Is a coconut a seed?
Botanically speaking, a coconut is a fibrous one-seeded drupe, also known as a dry drupe. However, when using loose definitions, the coconut can be all three: a fruit, a nut, and a seed. Botanists love classification. Coconuts are classified as a fibrous one-seeded drupe.
What is germination class 10th?
Complete Answer: Germination refers to the method by which an associated organism grows from a seed or a reproductive structure. This method is initiated by specific enzymes that become activated once the seed is exposed to water. The roots grow downwardly, and also the shoot grows upwards towards the soil surface.
What is Megasporogenesis 12?
The process of formation of a megaspore mother cell is known as megasporogenesis. The megaspore mother cell or MMC is a large cell containing dense cytoplasm and a prominent nucleus. The MMC undergoes reductional division or meiosis and forms four haploid megaspores.
What is Cleistogamy write one advantage and one disadvantage of it to the plants?
Flowers which are never open to ensure self-pollination is called cleistogamy. Cleistogamy has the advantage that the plant produces assured seed set even in the absence of pollinators and disadvantage is that self-pollination occur which reduces chances of variation and evolution of genetically superior progeny.
What are three advantages of seed and fruit dispersal?
Abstract. Seed dispersal can be advantageous (1) in escape from density-or distance-dependent seed and seedling mortality, (2) by colonization of suitable sites unpredictable in space and time, and (3) by directed dispersal to particular sites with a relatively high probability of survival.
What are the advantages of seed dispersal Class 7?
(i) Seed dispersal prevents the overcrowding of plants in an area. (ii) Seed dispersal prevents the competition for water, minerals and sunlight among the same kind of plants. (iii) Seed dispersal helps the plants to grow in new places (or new habitats) for wider distribution.
What advantages have seeds over spores quizlet?
an advantage is seeds provide a protective coat and nutrients. Advantages would be it doesn’t take much in the way of energy to produce a spore as opposed to making seeds and fruit.
