Unit 1 Review

Which phrase best describes the function of mitochondria?

• Located in the cytoplasm

• Bacteria-sized organelle

• Converts energy for cell use

• Contains a folded inner membrane

Which cell organelle stores DNA?

• Cell wall

• Cell membrane

• Vacuole

• Nucleus

The purpose of the cell wall is to-

• regulate what goes into and out of a cell

• control the functions of a cell

• convert energy from food into energy for a cell

• provide structure for a cell

Which of the following statements accurately represents the differences in plant and animal cells?

• Only plant cells have a cell wall, chloroplasts, and a large vacuole.

• Only animal cells have a cell wall, chloroplasts, and a large vacuole

• Only plant cells have a cell membrane, mitochondria, and cytoplasm

• Only animal cells have a cell membrane, mitochondria, and cytoplasm

The primary function f the chloroplast is to-

• convert food into energy a cell can use

• control the functions of a cell and control genetic traits

• convert radiant energy into chemical energy through photosynthesis

• store water and nutrients

Students observed cells under the microscope. They observed that the cells had a cell wall, cell membrane, nucleus, and many chloroplasts. Which observation helps students identify the type of cell observed?

• The presence of a nucleus means the cells are from a plant.

• The presence of a cell membrane means that the cells are from an animal

• The presence of chloroplasts means that the cells are from a plant

• The presence of a cell wall means that the cells are from an animal

A school’s cafeteria kitchen has a large, walk-in refrigerator where food is stored for lunch later in the week. Which cell organelle has a function that is similar to the refrigerator?

• Vacuole

• Nucleus

• Chloroplast

• Mitochondrion

In what ways do plant and animal cells differ?

• Plant cells have cell walls and chloroplasts.

• Animal cells have cell walls and chloroplasts.

• Plant cells have a nucleus and mitochondria.

• Animal cells have a nucleus and mitochondria.

The fluid surrounding the organelles of a cell is the —

• chloroplast

• cytoplasm

• mitochondria

• cell membrane

According to cell theory, what do each of the following organisms have in common?

   

• They can all reproduce by spontaneous generation.

• Each organism is able to photosynthesize.

• Cells are the basic unit of structure for each organism.

• They are all made up of the same kinds of atoms.
