Unit 3 Review

Mitosis is a process by which

• gametes are formed

• cytokinesis occurs

• cells grow larger

• a cell's nucleus divides

The purpose of mitosis is to produce

• copies of cells that are different than the parent cell

• four haploid identical cells

• shared proteins and ribosomes

• copies of cells that are identical to the parent cell

During normal mitotic cell division, a parent cell having eight chromosomes will produce two daughter cells, each containing

• two chromosomes ​

• four chromosomes

• eight chromosomes

• sixteen chromosomes

What is the end result of mitosis?

• Two genetically different cells

• Four genetically identical cells

• Two genetically identical cells

• Four genetically different cells

Which phase of mitosis is characterized by the alignment of chromosomes in the center of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

During which phase of mitosis do the sister chromatids separate and move towards opposite poles of the cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

Diffusion is the movement of molecules from

• an area of high concentration to an area of low concentration
• an area of low concentration to an area of equal concentration
• an area of high concentration to an area of equal concentration
• an area of low concentration to an area of high concentration

Which cell structure produces ATP

• Nucleus
• Endoplasmic reticulum
• Golgi apparatus
• Mitochondria

In addition to light and chlorophyll, photosynthesis requires

• Oxygen and nitrogen
• Salt and sugar
• Iron and magnesium
• Water and carbon dioxide

The process that is occuring in the diagram is

• Diffusion

• Osmosis
