Answer:
a . 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. One of the ways that plants can produce offspring is by making seeds.
b. Climbing roots are adventitious roots that arise from nodes and attach themselves to some support and climb on the bark of any tree. For example, money plant, betel. The betel (Piper betle) is the leaf of a vine belonging to the Piperaceae family.
c. 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.
d . Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities
