Define Cell

When a cell is not dividing the DNA is loosely spread throughout the nucleus in a thread-like form called

• chromatin

• chromosomes

• cytosol

• ribosomes

The plasma membrane not only provides a protective boundary for the cell but also determines w/c substance enters or exits the cell. We call this characteristics:

• diffusion

• membrane potential

• osmosis

• selective permeability

Proteins are assembled in this organelles

Because these organelles are responsible for providing most of the ATP needed by the cell, they are often referred to as the "powerhouse" of the cell. These are called:

• centrioles

• lysosomes

• mitochondria

• ribosomes

Choose the correct underlined word.

TRUE or FALSE

How many stages of mitosis are there?

DNA replication occurs during

• cytokinesis

• interphase

• metaphase

• prophase

TRUE or FALSE

All animal cells have cell walls
