• They have an endoplasmic reticulum

Which of the following is true of only plant cells?

• Plant cells have a nucleus

• Plant cells have cytoplasm

• Plant cells have a cell wall

• Plant cells have a cell membrane

Which proteins in the cell speed up chemical reactions without becoming part of the reaction?

• Lipids

• DNA

• Enzymes

• Glucose

What is the correct order of mitosis?

• Prophase, Metaphase, Anaphase, Telophase

• Prophase, Anaphase, Metaphase, Telophase

• Prophase, Telophase, Anaphase, Metaphase

• Metaphase, Prophase, Telophase, Anaphase

During metaphase, the:

• Nuclear membrane dissolves

• The cell splits into two

• Chromatids pull apart to opposite sides of the cell

• Chromosomes line up in the middle

During anaphase, the:

• Nuclear membrane dissolves

• The cell splits into two

• Chromatids pull apart to opposite sides of the cell

• Chromosomes line up in the middle

Mitosis is the process by which body cells divide while meiosis is the process by which reproductive cells form.  Unlike meiosis, cells produced through mitosis: 

• Are genetically different from the parent cell

• Have one-half the number of chromosomes of the parent cell

• Have double the number of chromosomes of the parent cell

• Are genetically identical to the parent cell

• 10%

• 25%

• 50%

• 90%

When a population stops growing due to limits in the environment, this is known as:
