Answer 1

Explanation:

1. 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.
2. Fertilisation or fertilization, also known as generative fertilisation, insemination, pollination, fecundation, syngamy and impregnation, is the fusion of gametes to initiate the development of a new individual organism or offspring.
3. The stamen is a male reproductive organ of a flower. It produces the pollen. The stamen has two parts: anther and stalk. The stalk is also called a filament.
4. In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the integument, forming its outer layer, the nucellus (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center.
5. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
6. the gas-filled float of some colonial coelenterates, such as the Portuguese man-of-war.
7. Conduction transfers heat via direct molecular collision. An area of greater kinetic energy will transfer thermal energy to an area with lower kinetic energy. Higher-speed particles will collide with slower speed particles. The slower-speed particles will increase in kinetic energy as a result.

Answer 2

1) the transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization.

2) the action or process of fertilizing an egg or a female animal or plant, involving the fusion of male and female gametes to form a zygote.

3) the pollen-producing male organ of a flower that consists of an anther and a filament

4) the part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed.

5) (of a plant or leaf) the exhalation of water vapour through the stomata.

For eg- "plants lose more than 90 per cent of their water through transpiration"

6) (in mangroves and other swamp plants) an aerial root specialized for gaseous exchange

7) the transmission of impulses along nerves.
