What is an organelle?

• An organelle is a type of organism that can live independently.
• An organelle is a fluid that fills the cell and provides nutrients.
• An organelle is a genetic material found in the nucleus of a cell.
• An organelle is a specialized structure within a cell that performs a specific function.

List two places you can find ribosomes in the cell.

• Nucleus
• Cytoplasm, Endoplasmic Reticulum
• Mitochondria
• Golgi Apparatus

If your body didn’t have vesicles, what would happen? (or not be able to happen?)

• Vesicles are only important for energy production.
• Transport of materials would be faster without vesicles.
• Cells would function normally without any changes.
• Cells would be unable to transport materials efficiently,

What does hydrophobic mean?

• Attracting water or mixing easily with water.
• Being soluble in oil or fats.
• Hydrophobic means repelling water or not mixing with water.
• Having a strong affinity for moisture.

What is the best way to describe a cell membrane?

• A solid wall that protects the cell from external damage.
• A selectively permeable barrier composed of a phospholipid bilayer.
• A rigid structure that prevents all substances from entering the cell.
• A fluid layer that allows only water to pass through.

What is the significance of the cell membrane being selectively permeable?

• It prevents any substances from entering the cell.
• It allows all substances to freely pass in and out of the cell.
• it regulates the internal environment of the cell, allowing essential substances to enter while keeping harmful ones out.

• It only allows water to enter the cell while blocking all other substances.
