Question

select the choice(s) that characterizes each of the following statements.
a diffusion
b osmosis
c endocytosis
d exocytosis
e filtration
f phagocytosis
g pinocytosis
20 requires atp
21 driven by fluid pressure
22 flows from an area of greater pressure to lesser pressure
23 moves water through a semipermeable membrane
24 provides for cellular uptake of solid or large particles from the cell exterior
25 transports amino acids, some sugars and sodium through the plasma membrane

Explanation:

• 20: Endocytosis (C), Exocytosis (D), Phagocytosis (F), Pinocytosis (G) are active - transport processes that require ATP.
• 21: Filtration (E) is driven by fluid pressure.
• 22: Diffusion (A) and Filtration (E) flow from an area of greater pressure to lesser pressure. But considering the context, diffusion is a more general process for this description.
• 23: Osmosis (B) moves water through a semi - permeable membrane.
• 24: Phagocytosis (F) provides for cellular uptake of solid or large particles from the cell exterior.
• 25: Facilitated diffusion (not in the given options but if we consider the closest among the given ones, it could be Diffusion (A) as it can transport small molecules like amino acids, some sugars and sodium through the plasma membrane).
