Cell Structure & Functions

What is the function of the nucleus in a cell?

• Synthesizes proteins

• Regulates cell shape

• Control center and contains genetic material (DNA)

• Provides energy for the cell

Name the organelle responsible for producing energy in a cell.

• Mitochondria

• Chloroplast

• Endoplasmic reticulum

• Nucleus

Differentiate between plant and animal cells in terms of cell wall presence.

• Plant cells have a cell wall made of cellulose, while animal cells have a cell wall made of chitin

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

• Both plant and animal cells have a cell wall

• Plant cells have a cell wall, while animal cells do not.

Explain the cell theory in your own words.

• In the cell theory, cells are not considered the basic unit of life.

• The cell theory states that all living organisms are composed of cells, cells are the basic unit of structure and function in living organisms, and all cells come from pre-existing cells.

• According to the cell theory, cells can spontaneously generate from non-living matter.

• The cell theory states that cells are only found in animals, not plants.

What is the process by which cells divide called?

• Cellular fission

• Nuclear fusion

• Cytoplasmic separation

• Cell division

Identify the organelle responsible for protein synthesis.

• Ribosome

• Golgi apparatus

• Mitochondria

• Endoplasmic reticulum

Describe the function of the cell membrane.

• The function of the cell membrane is to regulate the passage of substances into and out of the cell.

• The cell membrane acts as a barrier to prevent any substances from entering the cell.

• The cell membrane is responsible for producing energy for the cell.

• The cell membrane functions as a storage organelle.

Compare and contrast the structure of a prokaryotic cell with a eukaryotic cell.

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack these structures.

• Prokaryotic cells are generally larger and more complex in structure compared to eukaryotic cells.

• Eukaryotic cells lack a true nucleus and membrane-bound organelles, while prokaryotic cells have these structures.

• Prokaryotic cells lack a true nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles. Prokaryotic cells are generally smaller and simpler in structure compared to eukaryotic cells.

What is the function of the mitochondria in a cell?

• Stores genetic material

• Produces energy (ATP) through cellular respiration

• Regulates cell division

• Synthesizes proteins

List three differences between a plant cell and an animal cell.

• Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells do not have a cell wall, chloroplasts, or a large central vacuole.

• Plant cells have lysosomes, while animal cells do not have lysosomes.

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

• Plant cells have cilia, while animal cells do not have cilia.
