Question

what type of cell transport goes against the concentration gradient? *
diffusion
active
osmosis
facilitated diffusion

what is the difference between a plant cell and animal cell? *
cell membrane
nucleus
cell wall
mitochondria

Explanation:

First Question (Cell Transport):

• Diffusion: Moves with the concentration gradient (from high to low), no energy needed.
• Active Transport: Requires energy (ATP) and moves substances against the concentration gradient (from low to high).
• Osmosis: A type of diffusion (water) with the concentration gradient.
• Facilitated Diffusion: Moves with the concentration gradient, uses proteins. So the correct answer is Active.

• Cell Membrane: Both plant and animal cells have a cell membrane.
• Nucleus: Both have a nucleus.
• Cell Wall: Plant cells have a cell wall (made of cellulose), animal cells do not.
• Mitochondria: Both have mitochondria. So the correct answer is Cell wall.

Answer:

B. Active (assuming the second option is labeled as B, but from the options, the "Active" option is the correct one. So the answer is the option with "Active" text, i.e., the second radio button option: Active)

Second Question (Plant vs Animal Cell):
