No 1 answer They require sophiscated tools. The microscopes help in the study of cells. The molecular study of the cells are performed by the help of electron microscope. So, we can say that cells are microscopic in nature.

Explanation:

No 2 answer The nucleus is the largest and most prominent of a cell's organelles (Figure 3.7). The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins.

No 3 answer Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

eduard

Answer:

Anthocyanin is not produced in the plant cells

Explanation:

Anthocyanin is not produced in plant cells with the genotype mm.

As you can see from the question above, anthocyanin is responsible for the purple color of the flowers. Anthocyanin is encoded by the M gene, which is a dominant gene. Because it is a dominant gene, we know that it will be expressed in plants with the Mm and MM genotype, but will not be encoded by plants with the mm genotype. With this we can conclude that plants that have the mm genotype do not have purple color, because anthocyanin is not produced in the plant cells of these plants, since they do not have the M gene.
