Answer:
(2) low power: 100 small pollen grains
high power: 25 large pollen grains
Explanation:
Compound light microscopes are devices used to greatly magnify objects. They have several objective lenses, a low-power lens magnifies 10 times (10X) the objects, and the high-power lens magnifies them 40 times (40X).
For that reason, when observing the pollen grains with the high-power lens the student will see them bigger than with the low-power lens. However, the field of view (the visible area through a lens) is reduced when a higher power lens is used, so fewer pollen grains will be seen.
The answer therefore is the option of higher number of pollen grains of small size for the low-power lens, and lower number of pollen grains of larger size for the high-power lens.
Live only on land. There are many species of underwater plants on Earth. :)
Why do cells have a plasma membrane
A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The cell membrane regulates the flow of substances into and out of the cell.
The cell membrane, commonly referred to as the plasma membrane, serves as the body of a cell. It also keeps the environment inside the cell constant, and that membrane has many functions. One is to introduce nutrients into the cell while removing toxic chemicals from it. Another is that the cell's plasma membrane, which is its outer membrane, will have proteins that interact with other cells. These proteins may be glycoproteins, which also contain a sugar moiety, or lipid proteins, which contain both a protein and a fatty acid. Proteins that stick outside of the plasma membrane also allow for cell-to-cell communication. The cell membrane also provides some structural support.
