chloroplast
True or False: The rough endoplasmic reticulum is studded with ribosomes.
True
What is the role of the cell membrane?

B) Lysosome
What is the function of the cytoskeleton?
The cytoskeleton provides structural support and aids in cell movement.
Fill in the blank: The __________ is the site of ATP production in the cell.
mitochondria
True or False: Peroxisomes are involved in the detoxification of harmful substances.
True
What is the function of the vacuole in plant cells?

Fill in the blank: The __________ is a network of protein filaments that helps the cell maintain its shape.
cytoskeleton
True or False: Ribosomes can be found floating freely in the cytoplasm.
True
What is the function of the nucleolus?
The nucleolus is responsible for ribosome production.
Multiple choice: Which organelle modifies proteins after they are synthesized? A) Ribosome B) Golgi apparatus C) Mitochondria
B) Golgi apparatus
What is the role of the plasma membrane?
The plasma membrane regulates what enters and exits the cell and provides protection.
Fill in the blank: The __________ is involved in detoxifying chemicals and metabolizing drugs.
smooth endoplasmic reticulum
True or False: Chloroplasts contain chlorophyll, which is essential for photosynthesis.
True
What is the main function of centrioles?
Centrioles are involved in cell division and the formation of spindle fibers.

C) Mitochondria
What is the function of the cell wall?
The cell wall provides structure and protection to plant cells.
Fill in the blank: The __________ are small membrane-bound sacs that transport substances within the cell.
vesicles
True or False: The Golgi apparatus is involved in the synthesis of ribosomes.
False
What is the function of the rough endoplasmic reticulum?

endoplasmic reticulum
True or False: Plant cells have both chloroplasts and mitochondria.
True
What is the function of the plasma membrane in relation to homeostasis?
The plasma membrane helps maintain homeostasis by controlling the movement of substances into and out of the cell.
