Answer:
"Lipids are an essential component of the cell membrane. The structure is typically made of a glycerol backbone, 2 fatty acid tails (hydrophobic), and a phosphate group (hydrophilic)."
Explanation:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane. ... Cell adhesion molecules allow cells to identify each other and interact.
Answer: you decide
Explanation:
The eukaryoitic cells make their own food and are most commonly found in plants. Prokaryotic cells don't need chloroplast or cell wall. Both have a nucleus, and mitochondria, Based on this make your answer.
Answer:
1.Small cell: has larger surface-area to volume ratio
Bigger Cell: has little space to volume ratio
2. Surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time.
Amoeba and some bacteria's are flat and have large surface area to volume ratio. So the diffusion rate is very high due to large surface area.
Where as humans have small surface area: volume so diffusion is very slow or does not take place at all.
3. Diffusion and Cell Size
The larger a cell is, the greater the surface area available for diffusion. ... Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.
