Exploring Cell Structures

What is the function of the cell membrane?

• The cell membrane provides energy for cellular processes.

• The cell membrane stores genetic information.

• The cell membrane acts as a site for protein synthesis.

• The cell membrane regulates the movement of substances in and out of the cell.

Name one organelle found in the cytoplasm.

• chloroplast

• ribosome

• nucleus

• mitochondrion

What is the role of the nucleus in a cell?

• The nucleus produces energy for the cell.

• The nucleus transports nutrients within the cell.

• The nucleus controls cell activities and stores genetic information.

• The nucleus is responsible for protein synthesis.

Describe the function of mitochondria.

• Mitochondria convert nutrients into energy (ATP) through cellular respiration.

• Mitochondria store genetic information for the cell.

• Mitochondria regulate cell division and growth.

• Mitochondria are responsible for protein synthesis.

What is the purpose of ribosomes in a cell?

• To transport nutrients within the cell

• The purpose of ribosomes in a cell is to synthesize proteins.

• To produce energy for the cell

• To store genetic information

How do lysosomes contribute to cellular health?

• Lysosomes produce energy for the cell.

• Lysosomes store genetic information.

• Lysosomes are responsible for protein synthesis.

• Lysosomes contribute to cellular health by degrading waste and recycling cellular components.

What is the difference between rough and smooth endoplasmic reticulum?

• The rough endoplasmic reticulum is found only in plant cells, while the smooth endoplasmic reticulum is found only in animal cells.

• The rough endoplasmic reticulum has ribosomes and synthesizes proteins, while the smooth endoplasmic reticulum lacks ribosomes and synthesizes lipids.

• Both rough and smooth endoplasmic reticulum are identical in function and structure.

• The rough endoplasmic reticulum is involved in DNA replication, while the smooth endoplasmic reticulum is not.

What is the function of the Golgi apparatus?

• The Golgi apparatus is responsible for DNA replication.

• The Golgi apparatus detoxifies harmful substances.

• The Golgi apparatus functions to modify, sort, and package proteins and lipids.

• The Golgi apparatus generates ATP for energy.

Explain the role of chloroplasts in plant cells.

• Chloroplasts enable photosynthesis in plant cells, converting light energy into chemical energy.

• Chloroplasts store water for plant cells.

• Chloroplasts provide structural support to plant cells.

• Chloroplasts are responsible for cellular respiration.

What is the significance of the cytoskeleton in a cell?

• The cytoskeleton is significant for maintaining cell shape, providing structural support, enabling intracellular transport, and facilitating cell division.

• The cytoskeleton helps in the synthesis of proteins.

• The cytoskeleton is responsible for energy production in the cell.

• The cytoskeleton is involved in the storage of genetic material.
