What is the function of Stomata?
Answer: Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells (Figure 3). Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.

The surface area to volume ratio of an organism decreases as its size increases. Ultimately helps organisms, but at the other hand, can't move across the membrane on its own to bring materials like nutrients and water in their cells, or to remove waste material. Specialized transport systems are required for large multicellular organisms.

3. Which organism has DNA located in three organelles?
A. A sponge
B. A fern plant C. A flatworm
D. A bacterium
In a FERN PLANT, DNA is located in three different organelles (Option B).
Plants are organisms that have chloroplasts, mitochondria, and cell nuclei.In a eukaryotic cell, the genetic material (i.e., DNA) is mainly found in the nucleus, which is an organelle bounded by a double-membrane (bacteria don't have nuclei).However, mitochondria and chloroplasts are also membrane-bound organelles that have their own genetic material.Chloroplasts are only found in plants and algae (sponges and flatworms don't have chloroplasts).In conclusion, in a FERN PLANT, DNA is located in three different organelles (Option B is correct).
