Stack of flat, membrane-enclosed spaces containing enzymes that process, sort, and deliver proteins. Located near the nucleus.

The Golgi Apparatus is responsible for processing, sorting, and delivering proteins within the cell. It is a stack of flat membrane-enclosed spaces near the nucleus, distinct from the options mentioned.

Explanation

The Golgi Apparatus is responsible for processing, sorting, and delivering proteins within the cell. It is a stack of flat membrane-enclosed spaces near the nucleus, distinct from the options mentioned.

6. What is a vesicle?

A type of cell membrane that surrounds and protects the cell.

A large organelle responsible for energy production in the cell.

A structure found only in plant cells that stores water and nutrients.

Small organelle that contains and transports maerials within the cytoplasm. Located anywhere in the cytoplasm.

Vesicles are small organelles involved in intracellular transport, not to be confused with other organelles or structures in the cell.

Explanation

Vesicles are small organelles involved in intracellular transport, not to be confused with other organelles or structures in the cell.

7. What is the function of the mitochondrion?

A DNA fragment found in the nucleus of a cell.

Bean-shaped organelle that supplies energy to the cell and has its own ribosomes and DNA. Located in the cytoplasm.

An organelle responsible for synthesizing proteins in the cell.

A structure that stores water in a cell.

Mitochondria are known as the powerhouse of the cell, producing ATP through cellular respiration. They have a unique structure and function that sets them apart from other organelles in the cell.

Explanation

Mitochondria are known as the powerhouse of the cell, producing ATP through cellular respiration. They have a unique structure and function that sets them apart from other organelles in the cell.

8. What is the function of a vacuole in a cell?

B. Organelle responsible for cell movement.

C. Organelle that contains the cell's genetic material.

A. Organelle involved in protein synthesis.

D. Organelle that aids in cellular respiration.

A vacuole is an organelle that serves as a storage unit within a cell, holding various substances needed for cellular processes. It is not involved in protein synthesis, cell movement, or housing the cell's genetic material. Additionally, vacuoles do not play a direct role in cellular respiration.

Explanation

A vacuole is an organelle that serves as a storage unit within a cell, holding various substances needed for cellular processes. It is not involved in protein synthesis, cell movement, or housing the cell's genetic material. Additionally, vacuoles do not play a direct role in cellular respiration.

9. What is a lysosome?

Cell membrane that regulates what enters and leaves the cell.

Organelle that contains enzymes. Located near the Golgi Apparatus.

Powerhouse of the cell where cellular respiration occurs.

Organelle that stores genetic material and controls cell activities.

A lysosome is an organelle that contains enzymes and is responsible for breaking down cellular waste material. It is typically located near the Golgi Apparatus, not to be confused with other organelles such as the cell membrane, mitochondria, or nucleus.

Explanation

A lysosome is an organelle that contains enzymes and is responsible for breaking down cellular waste material. It is typically located near the Golgi Apparatus, not to be confused with other organelles such as the cell membrane, mitochondria, or nucleus.

10. What is a centriole?

Small cylinder-shaped organelle made of protein tubes arranged in a circle; aids mitosis. Located just outside the nucleus.

A type of musical instrument used in orchestras.
