What is the function of the nucleus in a cell?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression.

Front

What is the cell theory?

Back

The cell theory states that: 1) All living organisms are composed of cells, 2) Cells are the basic unit of life, 3) All cells arise from pre-existing cells.

Front

What is the role of the cell membrane?

Back

The cell membrane is a selectively permeable barrier that controls what enters and leaves the cell, maintaining homeostasis.

Front

What is the site of protein synthesis in a cell?

Back

Ribosomes are the sites of protein synthesis, where amino acids are assembled into proteins.

Front

What is the function of lysosomes?

Back

Lysosomes contain digestive enzymes that break down worn-out parts of the cell and help in waste disposal.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, generating ATP through cellular respiration.

Front

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

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), and in the transport of materials within the cell.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the role of the cytoskeleton?

Back

The cytoskeleton provides structural support to the cell, helps in cell movement, and plays a role in intracellular transport.
