Q

asexual reproduction in plants

A

Plants can reproduce by asexual (vegetative) means. Asexual plants are able to reproduce through structures such as rhizomes, plantlets, or runners. The new plants are genetically identical to the parent plant, unlike sexual reproduction.

Q

sexual reproduction in plants

A

Plants can reproduce sexually using structures found in the plant flower. The male reproductive structure
produces sperm cells (pollen). The female reproductive structures include the ovule that produces the egg cells (ova).

Q

pollination

A

The transfer of pollen from the anthers of a flower to the stigma of the same flower or of another flower. Flowers are bright and colorful to attract pollinators like bees. Pollination is a prerequisite for fertilization: the fusion of nuclei from the pollen grain with nuclei in the ovule. Fertilization allows the flower to develop seeds which then goes through germination ‐ the process in which a plant emerges from a seed and begins growth.

Q

nutrient absorption

A

the body breaking down & absorbing nutrients from food
