Cell biology

What is cellular respiration?

• A process that converts sunlight into energy

• A method of photosynthesis in plants

• The process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

• A way for cells to store energy for later use.

What is homeostasis?

• Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes.

• Homeostasis is the ability of an organism to reproduce in varying conditions.

• Homeostasis refers to the way organisms adapt to their environment over time.

• Homeostasis is the method by which organisms obtain energy from food.

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack these features.

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.

• Prokaryotic cells are larger than eukaryotic cells and have more complex structures.

• Eukaryotic cells can only be unicellular, while prokaryotic cells can be multicellular.

What is the role of the cytoplasm?

• The cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site of many metabolic processes.

• The cytoplasm is responsible for the synthesis of proteins only.

• The cytoplasm acts as a barrier to protect the cell from external damage.

• The cytoplasm is primarily involved in the storage of genetic material.

What are the characteristics of all living things?

• Exhibit growth and development, respond to their environment, reproduce, and maintain homeostasis.

• Have the ability to swim and fly.

• Can photosynthesize and produce their own food.

• Are capable of living in extreme temperatures.

What is the function of the cell membrane?

• It provides energy to the cell.

• It regulates what enters and exits the cell, providing protection and structural support.

• It stores genetic information.

• It synthesizes proteins.

What organelle is responsible for breaking down waste in the cell?

• Mitochondria

• Lysosomes

• Ribosomes

• Endoplasmic Reticulum

What is the role of ribosomes in a cell?

• Ribosomes are responsible for energy production in the cell.

• Ribosomes are responsible for protein synthesis by translating messenger RNA (mRNA) into polypeptide chains.

• Ribosomes help in the replication of DNA.

• Ribosomes are involved in the transport of nutrients within the cell.

What is the function of the Golgi apparatus?

• It synthesizes ribosomes in the nucleus.

• It modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

• It produces ATP through cellular respiration.

• It stores genetic information in the form of DNA.

What is a vacuole?

• A type of cell that produces energy

• A sac-like organelle that stores water, food, and other substances within a cell.

• A structure that helps in cell division

• A part of the cell responsible for protein synthesis
