Which of the following is found in a eukaryotic cell, but is not found in a prokaryotic cell?

• Cytoplasm

• Cell membrane

• Nucleus

• Flagella

Cells often store materials like water, salts, proteins and carbohydrates in sac-like structures called

• vesicles

• lysosomes

• mitochondria

• vacuoles

Which principle of cell theory best supports the idea that new cells will replace damaged cells in a scraped knee?

• Cells are the basic unit of life.

• All living things are made of one or more cells.

• All cells come from other cells.

• The nucleus of cells in animals reproduces when exposed to air.

Where can you find ribosomes in the cell?

• Cytoplasm

• Rough ER

• Smooth ER

• A and B

Which of the following organelles would you not find in a plant cell?

• Chloroplast

• Centrioles

• Central vacuole

• Cell wall

According to cell theory,

• all multicellular organisms are composed of prokaryotic cells.

• only cells like the eukaryote can carry out the functions of life.

• single celled organisms are only capable of asexual reproduction.

• even primitive cells, like the prokaryote, can carry out the functions of life.

This process occurs when the cell uses energy to bring something in from outside the cell.

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

The process of keeping the internal environment of the body stable by making adjustments to changes in the external environment is known as homeostasis. Which of the following is a mechanism for maintaining homeostasis at the cellular level?

• Passive transport, where ATP is used to facilitate the movement of molecules from high to low concentrations

• Facilitated transport, where enzymes are used to increase the rate of solvent transfer across a membrane

• Active transport, where the solution is pumped across a membrane to from high to low concentrations

• Active transport, where molecules are pumped across the cell membrane against the gradient from low to high concentration
