Answers
Answer:
Flower is the reproductive organ of the plant. Specialised reproductive parts in a flower are stamen (male) and pistil (female).
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation.
In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as Cuscuta.
Climbing roots are the adventitious roots that arise from the nodes or internodes in plants having weak stems. These roots help the plants in climbing by penetrating the cracks of the support, as in Pothos (money plant) or they may stick firmly to support by secreting a cementing gummy substance, as in Ficus pumila.
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). This pollination does not require an investment from the plant to provide nectar and pollen as food for pollinators.
