(26 cards)
What is the function of the nucleus in a cell?
The nucleus acts as the control center of the cell, housing genetic material and regulating gene expression.
True or False: Mitochondria are known as the powerhouse of the cell.
True
What structure is responsible for producing proteins in a cell?
Ribosomes
Fill in the blank: The __________ is a semi-permeable membrane that surrounds the cell.
cell membrane
What is the primary function of the endoplasmic reticulum?
To synthesize proteins and lipids.
Which organelle is involved in energy production?
Mitochondria
What is the role of the Golgi apparatus?
To modify, sort, and package proteins and lipids for secretion or use within the cell.
True or False: Plant cells have chloroplasts, while animal cells do not.
True
What structure provides support and rigidity to plant cells?
Cell wall
What is the function of lysosomes?
To digest and break down waste materials and cellular debris.
Multiple Choice: Which of the following is NOT found in animal cells? A) Chloroplasts B) Mitochondria C) Nucleus D) Ribosomes
A) Chloroplasts
What is the function of the cytoplasm?

cytoskeleton
What do we call the fluid-filled sac found in plant cells that stores substances?
Vacuole
True or False: The rough endoplasmic reticulum is studded with ribosomes.
True
What is the primary function of chloroplasts?
To conduct photosynthesis and convert solar energy into chemical energy.
