Plant Processes Quick Check

Answer 1

1. Photosynthesis: The process by which plants use sunlight, carbon dioxide, and water to produce glucose (a form of sugar) and release oxygen as a byproduct. This process occurs in the chloroplasts of plant cells.

2. Respiration: The process by which plants convert glucose and oxygen into energy, carbon dioxide, and water. This process occurs in the mitochondria of plant cells.

3. Transpiration: The process by which plants lose water through their leaves. This helps to transport nutrients from the roots upward to the rest of the plant and also helps to cool the plant.

4. Germination: The process by which a seed begins to grow and develop into a new plant. This process usually involves the absorption of water, followed by the emergence of the radicle (the first root) and the plumule (the first shoot).

5. Pollination: The transfer of pollen from the male reproductive organs (stamen) to the female reproductive organs (pistil) of a flower, which is necessary for fertilization and the production of seeds.

6. Fertilization: The process by which the male gamete (sperm) fuses with the female gamete (egg) to form a zygote, which eventually develops into a new plant.

7. Growth: The increase in size or number of cells in a plant. This is achieved through the process of cell division and elongation.

8. Reproduction: The process by which plants produce offspring. This can occur thual reproduction, involving the formation of seeds, or through asexual reproduction, which includes methods such as vegetative propagation and spore formation.
