Question

cell transport guided notes

1. the cell membrane controls what enters and exits the cell to maintain an internal balance called
2. it is selectively , meaning it allows some molecules in and keeps other molecules out
3. what are the two types of cell transport?

Explanation:

1. Homeostasis is the internal balance a cell membrane helps maintain by controlling substances entering and exiting.
2. The cell - membrane is selectively permeable as it regulates molecule passage.
3. The two types of cell transport are passive transport (which doesn't require energy, like diffusion and osmosis) and active transport (which requires energy to move substances against a concentration gradient).

Answer:

1. Homeostasis
2. Permeable
3. Passive transport, Active transport
