What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What organelle is known as the powerhouse of the cell?

Back

Mitochondria are known as the powerhouse of the cell because they produce ATP, the energy currency of the cell.

Front

What process occurs in mitochondria?

Back

Cellular respiration occurs in mitochondria, where food is broken down to produce energy.

Front

What is cytoplasm?

Back

Cytoplasm is a gelatinous substance that fills the cell and contains organelles, providing a medium for biochemical reactions.

Front

What is the role of chloroplasts?

Back

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

Front

What is the function of lysosomes?

Back

Lysosomes contain digestive enzymes that break down waste materials and cellular debris.

Front

What is the structure of a cell membrane?

Back

The cell membrane is a phospholipid bilayer with embedded proteins that controls the movement of substances in and out of the cell.

Front

What is the nucleus?

Back

The nucleus is the organelle that contains the cell's genetic material (DNA) and regulates gene expression.

Front

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

Back

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

Front

What are vesicles?

Back

Vesicles are small membrane-bound sacs that transport materials within the cell and to the cell membrane for secretion.
