Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis. ... Plants provide many products for human use, such as firewood, timber, fibers, medicines, dyes, pesticides, oils, and rubber. Plants create habitats for many organisms.Asexual reproduction produces individuals that are genetically identical to the parent plant. Roots such as corms, stem tubers, rhizomes, and stolon undergo vegetative reproduction. Some plants can produce seeds without fertilization via apomixis where the ovule or ovary gives rise to new seedsWhenever the seed of a plant, that is genetically programmed to reproduce, is taken and put into the ground, water or other environment which it requires for the growth, it activates and all repeats again. The plants do not control wether to reproduce or not. Their DNA is just made the way they have to, unwillingly.They need water, sunlight and soil to live and grow properly. For a plant to grow like it is supposed to it needs to live where they can get what they need. Because there are many different kinds of plants they grow in many different places. The place that a plant lives in is called a habitat.Asexual reproduction produces individuals that are genetically identical to the parent plant. Roots such as corms, stem tubers, rhizomes, and stolon undergo vegetative reproduction.

vegetative reproduction

the reproduction in which the new plant body is developed by vegetative parts such as leaves, root , stem is called vegetative reproduction

it occurs in plants which don't have seeds . eg rose banana teakwood

reproduction in animals and plants

in animals their are 2 types of reproduction asexual and sexual reproduction

in asexual reproduction gametes are not involved and their is no formation of zygote .

in sexual reproduction gametes are involved and zygote is formed

asexual reproduction occurs in lower and unicellular animals

sexual reproduction occurs in higher and multicellular animals

asexual reproduction is divided into 7 types

1) budding

2) binary fission

3) regeneration

4) vegetative reproduction

5) spore formation

6)fragmentation

7) cyst formation

the formation of organism from the bud is called budding

budding takes place in invertebrates like hydra

the method of reproduction in which the cell of animal divides into 2 equal

halves and each half develops new organisms is called binary fission

the method of asexual reproduction in which the body of animals cut into pieces and each piece has the ability to regenerate the remaining parts is called regeneration

the process of formation of pieces or fragments in which each piece develops new body is called fragmentation
