Science 8 Vocab - Pages 29-31 - Cell Structure and Function

What is the role of the nucleus in a cell?

• It stores nutrients and toxins.

• It is responsible for photosynthesis.

• It controls the cell's activities and stores DNA.

• It surrounds the cell membrane and provides shape.

What does the cell membrane do?

• Provides protection and regulates the movement of substances in and out of the cell.

• Converts light energy into chemical energy.

• Stores waste products like harmful toxins.

• Surrounds the nucleus and holds DNA.

Which cell structure is only found in plant cells and provides shape?

• Cytoplasm

• Cell Wall

• Nucleus

• Vacuole

Match the following organelle functions with their descriptions.

• Function of lysosomes.

• To convert light energy into chemical energy via photosynthesis.

• Function of the cytoskeleton.

• To protect the organelles and hold them in place.

• Function of chloroplasts.

• To take in waste products and eliminate them.

• Function of mitochondria.

• To provide energy by breaking down glucose.

Match the following cellular functions with what vacuoles store and eliminate:

• Genetic material and nourishment

• Energy molecules like glucose

• Photosynthesis energy storage

What is the function of the cytoplasm?

• To store DNA and control cell activities.

• To hold organelles in place and protect them from damage.

• To regulate the movement of nutrients and toxins.

• To eliminate waste products like harmful toxins.

What is the role of the nucleolus?

• It controls all of the cell’s activities.

• It makes the cell’s ribosomes.

• It converts light energy into chemical energy.

• It transports proteins throughout the cell.

Match the following cell organelles with their functions.

• Lysosome

Match the following cell components with their functions.

• Mitochondria

• They are responsible for making ribosomes.

• Vesicles

• They are sacs that transport materials in the cell.

• Nucleolus

• They convert glucose into energy.

• Cytoskeleton

• They provide the cell with shape.
