The answer could be A.
A bacterial cell is about 0.2-20 um, while a typical eukaryotic cell is about 10-100um, according to many sources of research.
1.The nucleus is often considered to be the cell's control center.
(because it contains the DNA)
2.The cytoplasm consists of everything
inside the plasma membrane of the cell.
(actually it excludes the nucleus)
3.The plasma membrane forms
a boundary between the inside and outside of the cell. - it controls what can enter and what can't!
4.The cytoskeleton is essentially a "skeleton" inside the cell..
it maintains the form of the cell
5.The
rough endoplasmic reticulum is covered with
Ribosomes -they make the proteins!
6.Lysosomes
use enzymes to break down foreign matter and dead cells.
7.plant cells cells specifically have a cell wall, a large central
vacuole, and chloroplasts.-choloplasts are only found in plants!
Oxygen and glucose are the products of photosynthesis. Oxygen is used by plant for respiration or it gets dissipated in the air. Glucose is stored for feeding the plant. It is also stored in the form of starch
Quantity of Heat = Mass x Heat Capacity x Temperature Change
This may be shortened to:
q = mcΔT
where:
q = Quantity of heat in Joules (J) m = Mass of the substance in grams (g) c = Specific Heat Capacity (Jg-1) ΔT = Change in Temperature (Δ = This symbol is "delta", which is Greek for "change")
C.) Scanning electron microscope. You would not be able to see a whole insect with one of these.
Hope this helped :)
