8th Grade Cell Organelles and Functions

Which organelle is responsible for photosynthesis?

• Mitochondria

• Chloroplast

• Nucleus

• Ribosome

Which organelle is found in both plant and animal cells and produces energy?

• Chloroplast

• Mitochondria

• Cell wall

• Vacuole

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

• It stores nutrients.

• It provides structural support and protection.

• It synthesizes proteins.

• It transports materials within the cell.

Which organelle is the "control center" of the cell?

• Endoplasmic reticulum

• Golgi apparatus

• Nucleus

• Lysosome

Which structure is found in plant cells but not in animal cells?

• Cell membrane

• Nucleus

• Cell wall

• Mitochondria

How do vacuoles in plant cells differ from those in animal cells?

• Plant vacuoles are smaller and more numerous.

• Plant vacuoles are larger and help maintain cell structure.

• Animal vacuoles are larger and store pigments.

• Animal vacuoles are involved in photosynthesis.

What is the role of the cell membrane in cells?

• It provides structural support.

• It regulates the movement of substances in and out of the cell.

• It synthesizes proteins.

• It stores genetic information.

Which organelle produces ATP?

• Chloroplast

• Mitochondria

• Nucleus

• Golgi apparatus

What is the difference between chloroplasts and mitochondria?

• Both are involved in photosynthesis.

• Chloroplasts convert light energy into chemical energy, while mitochondria convert chemical energy into usable energy.

• Both are involved in cellular respiration.

• Chloroplasts store genetic information, while mitochondria synthesize proteins.

Which organelle maintains the shape and structure of plant cells?

• Cell membrane

• Cell wall

• Nucleus

• Ribosome
