Review-CH3 Introduction to Cells

All of the living material of a cell is called the

• cytoplasm.

• protoplasm.

• cytoplasmic matrix.

• cytology.

The cell theory states that all cells come from pre-existing cells and

• all living things form cells.

• all functions of life are carried on by the cells.

• all the functions of living organisms are carried on by the cells that make up the organism.

• the cell is made only by living organisms.

Organisms made up of cells that can operate independently but that normally tend to group together are called

• colonial.

• tissues.

• systems.

• organs.

The changing of the sol to gel phases of the cytoplasmic matrix can result in organelle movement called

• cytoplasm.

• cytoplasmic streaming.

• turgor pressure.

• cytoplasmic matrix.

Organelles found in most plant cells but not in animal cells are

• lysosomes.

• Golgi bodies.

• plastids.

• ribosomes.

What is made up of microfilaments and microtubules?

• cytoplasmic matrix

• vacuoles

• basal bodies

• cytoskeleton

The process by which some cells form tiny pockets in their cell membranes when they confront molecules too large to be absorbed is called

• pinocytosis.

• osmosis.

• phagocytosis.

• homeostasis.

The diffusion of water into a cell by osmosis results in a build-up of

• osmotic pressure.

• turgor pressure.

• membrane pressure.

• permeability.

The control center of most cell activity is the

• nucleolus.

• chromatin.

• chromosome.

• nucleus.

What contained in plant cell walls?

• cellulose.

• chloroplast.

• chlorophyll.

• endoplasmic reticulum.
