The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.
Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.
The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.
Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.
Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.
Answer:
It lacks nucleus.
Explanation:
Prokaryotic: cells that lack a true nucleus or membrane bound organelles.
- Pro- before
- Karyo- Nucleus
Well the offspring of the original cell are considered daughter cells (as they all reproduce) so with the knowledge I know when the cell doubles it’s going to look exactly like the mother cell and not just look but they all have the same job, which is to multiple. So I think that might be the answer. But if it’s multiple choice then I might be wrong because you didn’t provide any options.
