vacuole

A(n) ________ is formed around the material that works to bring it into the cell.

Membranes

________ contain integral proteins that can assist in the movement of larger particles.

Electrons

________ bounce off of and do not have to be cut into small slices.

Particles

________ tend to move from areas of high concentration to low concentration.

materials

Occurs when ________ have to move from areas of low to high concentration.

Envelopes

________ contain pores that only RNA can pass through.

plant cells

In ________- the central vacuole is filled with liquid that is used for photosynthesis + helps the plant stand upright.
