Structure and Function of Cells

What organelle controls what goes in and out of plant and animal cells?

• Cell Membrane

• Nucleus

• Mitochondria

• Ribosome

What is the function of ribosomes in a cell?

• They are responsible for energy production.

• They are responsible for protein synthesis.

• They are responsible for DNA replication.

• They are responsible for cell division.

What is the gel-like fluid that takes up most of the space inside the cell?

• Cytoplasm

• Nucleus

• Mitochondria

• Endoplasmic Reticulum

In eukaryotic cells, where are chromosomes carrying genetic information found?

• Cytoplasm

• Nucleus

• Ribosome

• Mitochondria

What is cytoplasm?

• The jelly-like substance within the cell membrane that contains organelles.

• The rigid outer layer of a plant cell.

• The control center of the cell that contains DNA.

• The fluid that fills the nucleus of a cell.

What is the function of the vacuole in plant cells?

• Stores nutrients and waste products, and helps maintain turgor pressure.

• Produces energy through photosynthesis.

• Transports materials within the cell.

• Provides structural support to the cell.

What is the role of the Golgi apparatus?

• It modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.

• It produces ATP through cellular respiration.

• It synthesizes ribosomal RNA and assembles ribosomes.

• It is responsible for the detoxification of harmful substances.

What is the function of the cell wall in plant cells?

• Provides structure and support to the cell.

• Regulates the movement of substances in and out of the cell.

• Stores nutrients and waste products.

• Facilitates photosynthesis in the cell.

What is the function of the endoplasmic reticulum?

• It assists in the production of proteins and lipids; the rough ER has ribosomes, while the smooth ER does not.

• It is responsible for energy production in the cell.

• It helps in the digestion of cellular waste.

• It stores genetic information for the cell.

What is the role of the nucleus in a cell?

• It houses the cell's genetic material and controls cellular activities.

• It produces energy for the cell.

• It helps in the synthesis of proteins.

• It regulates the cell's water balance.
