Cells Unit Review

Which statement is true according to the cell theory regarding plant and protista cells?

• Both plants and protista can produce new cells, but only protista can take in nutrients.

• Plants can take in nutrients, but only protista can produce new cells.

• Both plants and protista are unable to produce new cells or take in nutrients.

• Both plants and protista can take in nutrients and produce new cells.

Avery is observing a cell under a microscope. Which process describes the cell engulfing (or eating) a large particle?

• exocytosis

• division

• endocytosis

• reproduction

What is one primary purpose of cellular reproduction in organisms?

• To repair damaged tissues.

• To eliminate waste products.

• To maintain homeostasis.

• To increase the number of cells.

What is the primary function of chloroplasts in plant cells?

• Chloroplasts are used to synthesize proteins in plant cells.

• Chloroplasts convert sunlight into glucose (sugar/food) in plant cells.

• Chloroplasts generate ATP in plant cells.

• Chloroplasts are responsible for DNA synthesis in plant cells.

Sophia and Benjamin are studying how cells from different organisms are all able to function. They discover that cells

• are genetically identical.

• can use energy.

• contain the same organelles.

• undergo metamorphosis.

During a biology class, Isla and Ethan are discussing how cells produce energy to survive. What process are they talking about?

• cellular respiration

• cellular specialization

• cellular differentiation

• cellular transport

During a biology class, Olivia was asked where the cell membrane is located in the plant cell. What should she answer?

• on the outer most part of the plant cell

• In between the cell wall and the inside of the cell.

• floating around in the cytoplasm

• there is no cell membrane, only a cell wall

Abigail is learning about cellular processes in her biology class. She wonders, the process of exocytosis in a single cell is most similar to

• waste removal through the excretory system in a multicellular organism.

• the protective external barrier (skin) of the integumentary system in a multicellular organism.

• the transport of molecules through the circulatory system in a multicellular organism.

• food transport through the digestive system in a multicellular organism.

What role does mitosis play in skin repair?

• Mitosis allows skin cells to multiply and replace damaged cells.

• Mitosis causes skin cells to shrink and disappear.

• Mitosis helps skin cells to produce more ATP.

• Mitosis prevents skin cells from dividing.

Which organelle is responsible for energy production in both plant and animal cells?

• nucleus

• ribosome

• mitochondria

• Golgi apparatus
