Overview of Cell Structure

What three things do all cells have in common, regardless of their type?

• Cell wall, cytoplasm, DNA

• Cell membrane, nucleus, DNA

• Cell membrane, cytoplasm, DNA

• Nucleus, cytoplasm, cell wall

Which characteristic describes prokaryotic cells?

• They are complex cells found in plants and animals.

• They contain a nucleus and other specialized organelles.

• They are always unicellular organisms without a nucleus or membrane-enclosed organelles.

• They have a cell wall but lack genetic material.

How do you describe organelles?

• Organelles are functional components within cells that carry out specific tasks.
• Organelles are only found in plant cells.
• Organelles are the outer layer of the cell.
• Organelles are the same as organ systems in the body.

What is the role or function of the nucleus?

• The nucleus produces energy for the cell.
• The nucleus stores nutrients for the cell.
• The nucleus is responsible for protein synthesis.
• The nucleus controls cell activities and contains DNA.

Where do ribosomes are created?

• Golgi Apparatus
• Nucleolus
• Endoplasmic Reticulum
• Cytoplasm

What is the purpose of the endoplasmic reticulum?

• The endoplasmic reticulum is involved in DNA replication.
• The endoplasmic reticulum stores waste products.
• The endoplasmic reticulum is responsible for cellular respiration.
• The endoplasmic reticulum is responsible for the synthesis of proteins and lipids.

What happens to the proteins as they pass through the Golgi bodies?

• Proteins are transported directly to the nucleus.
• Proteins are broken down into amino acids.
• Proteins are stored for later use.
• Proteins are modified and sorted for their specific functions.

What is the main function of a lysosome in the cell?

• To synthesize proteins.
• To produce energy for the cell.
• The main function of a lysosome is to digest and break down waste materials and cellular debris.
• To store genetic information.

Which of the following is the purpose of the mitochondrion?

• To produce energy (ATP) for the cell.
• To store genetic information for the cell.
• To regulate cell division and growth.
• To synthesize proteins for the cell.

How does the cell maintains its shape?

• The cell maintains its shape through the cytoskeleton and cell membrane.
• The cell maintains its shape using enzymes and hormones.
• The cell maintains its shape by absorbing water and nutrients.
• The cell maintains its shape through the nucleus and ribosomes.
