5. What is the function of ribosomes?

Ribosomes are responsible for lipid synthesis in animal cells.

Ribosomes are only found in plant cells.

Ribosomes are only found in animal cells.

Ribosomes are found in plant and animal cells and are what make the surface of a rough endoplasmic reticulum rough.

Ribosomes are essential cellular organelles responsible for synthesizing proteins in all types of cells, not just in plant or animal cells. They are not involved in lipid synthesis.

Explanation

Ribosomes are essential cellular organelles responsible for synthesizing proteins in all types of cells, not just in plant or animal cells. They are not involved in lipid synthesis.

6. What is the function of the Golgi Apparatus?

B. The Golgi Apparatus stores genetic information within the cell nucleus.

A. The Golgi Apparatus is responsible for cell movement and locomotion.

C. The Golgi Apparatus produces energy for the cell through photosynthesis.

The Golgi Apparatus is involved in processing and packaging cellular materials, not cell movement, genetic storage, or energy production.

Explanation

The Golgi Apparatus is involved in processing and packaging cellular materials, not cell movement, genetic storage, or energy production.

7. What is the role of mitochondria in a cell?

The mitochondria is responsible for cell division.

The mitochondria aids in transporting materials within the cell.

The mitochondria helps in storing genetic information in the cell.

Mitochondria are known as the powerhouse of the cell as they generate energy through the process of cellular respiration. They are not involved in cell division, storing genetic information, or transporting materials within the cell.

Explanation

Mitochondria are known as the powerhouse of the cell as they generate energy through the process of cellular respiration. They are not involved in cell division, storing genetic information, or transporting materials within the cell.

8. What is the central organelle in a eukaryotic cell that contains the genetic material?

D.

Lysosomes are membrane-bound organelles that contain digestive enzymes. They are responsible for breaking down cellular waste materials, pathogens, and other unnecessary components in the cell.

Explanation

Lysosomes are membrane-bound organelles that contain digestive enzymes. They are responsible for breaking down cellular waste materials, pathogens, and other unnecessary components in the cell.

10. What is the function of the Cytoplasm?

C. It regulates cell division.

D. It controls the movement of substances into and out of the cell.

B

A. It stores genetic information.

The cytoplasm is a jelly-like substance that fills the cell and serves as the site for many metabolic reactions such as protein synthesis and energy production.

Explanation

The cytoplasm is a jelly-like substance that fills the cell and serves as the site for many metabolic reactions such as protein synthesis and energy production.

11. What is the function of centrioles?

B. DNA replication

C

A. Energy production

D. Cell wall synthesis

Centrioles primarily play a role in cell division by organizing the microtubules of the spindle apparatus.

Explanation
