Cell Organelles Flashcards
What is the function of the nucleus in a cell?
The nucleus stores the cell’s genetic material and coordinates activities such as growth, metabolism, and reproduction.
True or False: Ribosomes are responsible for protein synthesis.
True
Fill in the blank: The __________ is known as the powerhouse of the cell.
mitochondria
What is the primary function of the endoplasmic reticulum?
The endoplasmic reticulum is involved in the synthesis of proteins and lipids.
Which organelle is responsible for modifying, sorting, and packaging proteins?
Golgi apparatus
What structure is selectively permeable and surrounds the cell?
Cell membrane
True or False: Lysosomes contain enzymes that break down waste materials and cellular debris.
True
Which organelle is responsible for maintaining the cell’s shape and providing structural support?
Cytoskeleton
Fill in the blank: The __________ is a jelly-like substance that fills the interior of the cell.
cytoplasm
What is the function of the vacuole in plant cells?
The vacuole stores nutrients, waste products, and helps maintain turgor pressure.
Which organelle is involved in detoxifying harmful substances in the cell?
Smooth endoplasmic reticulum
True or False: The cell wall is found in both plant and animal cells.
False
What structure contains the cell’s genetic material?
Nucleus
Which type of ribosomes are found on the rough endoplasmic reticulum?
Bound ribosomes
Fill in the blank: The __________ is involved in the production of ATP.
mitochondria
What is the primary function of peroxisomes?
Peroxisomes break down fatty acids and detoxify harmful byproducts of metabolism.
Which organelle is responsible for the synthesis of lipids?
Smooth endoplasmic reticulum
True or False: Centrioles are involved in cell division.
True
What is the main function of the plasma membrane?
The plasma membrane regulates the movement of substances in and out of the cell.
Which organelle is involved in the degradation of cellular waste?
Lysosome
Fill in the blank: The __________ is a network of protein filaments that helps the cell maintain its shape.
cytoskeleton
What is the role of the nucleolus?
The nucleolus is involved in the production of ribosomes.
Which organelle is responsible for packaging and shipping proteins?
Golgi apparatus
True or False: Chloroplasts contain chlorophyll, which is essential for photosynthesis.
True
