Question

The cell would only be able to transport substances using active transport mechanisms. the cell would only be able to transport substances using active and passive transport mechanisms. the cell would only be able to transport substances using diffusion and osmosis. the transport of all substances across the cell membrane would stop.

a. The cell would only be able to transport substances using active transport mechanisms.
b. The cell would only be able to transport substances using active and passive transport mechanisms.
c. The cell would only be able to transport substances using diffusion and osmosis.
d. The transport of all substances across the cell membrane would stop.

Answer 1

The cell membrane allows for the transport of substances through various mechanisms, including active and passive transport. Osmosis is a specific type of passive diffusion that involves the movement of water across a cell membrane.

Step-by-step explanation:

The cell membrane allows for the transport of substances through various mechanisms, including active transport, passive diffusion, facilitated diffusion, co-transport, and endocytosis. Active transport requires cellular energy to move substances from an area of lower concentration to an area of higher concentration. Passive diffusion, on the other hand, allows substances to move from an area of higher concentration to an area of lower concentration without the need for cellular energy. Osmosis is a specific type of passive diffusion that involves the movement of water across a cell membrane. Therefore, the correct answer to the question is b. The cell would only be able to transport substances using active and passive transport mechanisms.
