Cell Structure and Function

What is the basic structural and functional unit of all living organisms?

• organ

• cell

• atom

• molecule

Which type of cell has a cell wall, chloroplasts, and a large central vacuole?

• Fungal cell

• Plant cell

• Bacterial cell

• Animal cell

What is the function of the cell membrane?

• The function of the cell membrane is to provide structural support to the cell.

• The function of the cell membrane is to control the movement of substances in and out of the cell.

• The function of the cell membrane is to produce energy for the cell.

• The function of the cell membrane is to store genetic information in the cell.

Which organelle is responsible for protein synthesis?

• ribosome

• mitochondria

• lysosome

• nucleus

What is the process by which molecules move from an area of high concentration to an area of low concentration?

• diffusion

• osmosis

• active transport

• endocytosis

What is the term for the movement of water across a selectively permeable membrane?

• diffusion

• osmosis

• filtration

• active transport

What is the function of the mitochondria?

• Store genetic information

• Regulate cell division

• Produce waste products

• Produce energy through cellular respiration

Which organelle is responsible for photosynthesis in plant cells?

• chloroplast

• mitochondria

• endoplasmic reticulum

• nucleus

What are the main differences between plant and animal cells?

• Animal cells have a cell wall while plant cells do not

• Plant cells have a nucleus while animal cells do not

• The main differences between plant and animal cells are the presence of a cell wall, chloroplasts, and a large central vacuole in plant cells, while animal cells lack a cell wall and chloroplasts and have smaller vacuoles. Animal cells may also have centrioles while plant cells do not.

• Plant cells have a flagellum while animal cells do not

What is the function of the nucleus in a cell?

• It controls the movement of substances in and out of the cell

• It is responsible for photosynthesis

• It stores genetic information and controls the cell's activities

• It produces energy through cellular respiration
