What is the function of lysosomes?
Lysosomes digest and break down waste materials and cellular debris.
True or False: The cell membrane is selectively permeable.
True
What is the role of the cytoskeleton?
The cytoskeleton provides structural support and facilitates cell movement.
Fill in the blank: The _______ is involved in the synthesis of lipids.
smooth endoplasmic reticulum
What organelle is responsible for photosynthesis in plant cells?
chloroplast
Multiple Choice: Which structure acts as the cell’s control center?
Nucleus
What is the function of the rough endoplasmic reticulum?
It is involved in protein synthesis and processing.
True or False: Ribosomes can be found floating freely in the cytoplasm.
True
What is the function of vacuoles in plant cells?
Vacuoles store nutrients, waste products, and help maintain turgor pressure.
Fill in the blank: The _______ helps maintain the shape of the cell.
cytoskeleton
What structure regulates what enters and exits the cell?
cell membrane
Multiple Choice: Which organelle is involved in the breakdown of fatty acids?
peroxisomes
What is the primary function of centrioles?
Centrioles assist in cell division by organizing the mitotic spindle.
True or False: All cells have a cell wall.
False
What is the role of the nucleolus?
The nucleolus is responsible for ribosome production.
Fill in the blank: The _______ is the site of ATP production.
mitochondria
What organelle is known as the ‘suicide bag’ of the cell?
lysosome
Multiple Choice: Which structure is involved in the transport of materials within the cell?
vesicles
What is the function of the plasma membrane?
It protects the cell and controls the movement of substances in and out.
True or False: Chloroplasts are found in all types of cells.
False
What is the function of the Golgi apparatus?
The Golgi apparatus modifies, sorts, and packages proteins for secretion.
