Answer 1

Answer:

3. There are several advantages of vegetative reproduction, mainly that the produced offspring are clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring.

4. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.

5. One can grow rose plant by the method of stem cutting . we just have to cut a stem of rose plant and put it into soil and water it and take care of it and it will grow .Jun 24, 2018.

Pea pods often use mechanical dispersal. When the seeds are ready, the pod dries up. ... When the seeds are ripe and ready, the dried fruit becomes a trigger. When an animal or human touches the plant, it bursts open and sprays the seeds everywhere.

The seeds of madar (aak) have hair which allow them to be carried away easily by the wind.

Lotus fruit has a spongy part that enables it to float. these plants grow near water and their seeds are carried to far off places by water. ... This causes the seeds to be thrown away from the parent plant.

Castor seeds have a warty appendage called the caruncle, which is a type of elaiosome. The caruncle promotes the dispersal of the seed by ants

Runner beans, broad beans, really almost any beans, explode to shed their seeds. Water dispersal – rivers and larger bodies of water can deposit seeds miles from their original plant. Similarly to wind dispersal, this is most effective when the seeds are light.

Most of the mango seeds are dispersed by animals, birds, and humans. Animals and birds just eat the flesh of mango fruits and drop the edible part on the ground. For example, elephants and other large animals are good seed dispensers because they swallow the whole fruit and it will end up as droplets of dung.

The seeds fall to the bottom of the pond. Lodged in mud, water lily seeds sprout and colonize a new location. This type of seed dispersal is called hydrochory -- seed dissemination by water transport. Seeds are also dispersed by birds or aquatic animals that eat the seeds for their aril coatings.
