water to pass through. How will water move in this
example?

A
A.
B.
C.
D.
B
more will move from A to B
move will move from B to A

Why does the sugar stay in the cell?
A.
B.
C.
D.
A
B
it is dissolved in the water
it is connected to the nucleus
it cannot pass through the membrane
it is a solid made of crystals.
Why does osmosis occur? It happens
because
A. gravity pulls all matter toward the center of
Earth.
B. water moves from high concentrations to
low.
C. cells are alive and only living things have
osmosis.
D. cells are the smallest parts of living things.
How do cells get energy from food?
A. Cells break food into smaller parts,
releasing energy.
B. Cells have electricity in the nucleus that
travels to the rest of the cell.
C. Cells create energy because they are able
to move.
D. The sun sends food through space that
turns into energy.
What do cells do with waste products?
A. They store wastes in the cell membrane.
B. Wastes are passed out through the cell
membrane.
C. Wastes are broken down into helpful
substances.
D. The cells store the wastes, which allows
them to grow.
Why are only plant cells able to produce
food from sunlight? Plant cells
A. have cell walls that tell the cell how to
produce food.
B. have cytoplasm which creates and stores
food.
C. have chloroplasts which is where food is
produced.
D. have a cell wall to give the plant support
and strength.
Which is a plant cell, A or B?
A. Cell A because plant cells are not round.
B. Cell A because plant cells have a cell wall that helps hold their shape.
C. Cell B because the oblong structures in cell B look like chloroplasts.
D. Neither is a plant cell. Plant cells do not have that maze-looking
structure.
What guides all cell processes?
A. genetic material in the nucleus
B. energy from the mitochondria
C. movement through the cell membrane
