• Hooke

• Calvin

• Schwann

• osmotic pressure

• permeability

• turgor pressure

• membrane pressure

The transport of dissolved substances into the cell for its use is called

• synthesis

• secretion

• digestion

• absorption

Chloroplasts contain

• cristae

• grana

• saccules

• liposomes

Which of the following people did not contribute research toward a component of cell theory?

• Pasteur

• Schleiden

• Schwann

• Virchow

The process by which fluid enters a cell in bulk by being surrounded and engulfed by the cell membrane is

• pinocytosis

• osmosis

• plasmolysis

• cytolysis

Since diffusion is a purely physical process (it requires no cellular energy), it could be a form of

• passive transport

• active transport

• turgor

• plasmolysis
