3.1 & 3.2 Cell Theory and Cell Organelles

Front

What is the control center of the cell?

Back

Nucleus: The organelle that contains the cell's genetic material and controls its activities.

Front

Where does photosynthesis occur in plant cells?

Back

Chloroplast: The organelle responsible for converting light energy into chemical energy through photosynthesis.

Front

What is the jelly-like substance that fills the cell?

Back

Cytoplasm: The fluid that fills the cell and holds organelles in place, providing shape and support.

Front

What is known as the powerhouse of the cell?

Back

Mitochondria: Organelles that produce energy (ATP) through cellular respiration.

Front

What organelle stores water and nutrients in a cell?

Back

Vacuole: A membrane-bound sac that stores water, food, and waste products.

Front

What is the function of ribosomes?

Back

Ribosomes: Organelles that synthesize proteins by translating messenger RNA.

Front

What is the role of the cell membrane?

Back

Cell Membrane: A protective barrier that regulates what enters and exits the cell.

Front

What is the function of the Golgi body?

Back

Golgi Body: An organelle that modifies, sorts, and packages proteins and lipids for secretion or delivery.

Front

What is the function of the endoplasmic reticulum (ER)?

Back

Endoplasmic Reticulum: A network of membranes involved in protein and lipid synthesis; includes rough (with ribosomes) and smooth (without ribosomes) ER.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells: Simple cells without a nucleus (e.g., bacteria); Eukaryotic cells: Complex cells with a nucleus (e.g., plant and animal cells).
