What is the function of ribosomes in a cell?

Back

Ribosomes are organelles where proteins are synthesized (made). They are present in all cells.

Front

What is a vesicle and its role in a cell?

Back

A vesicle is an organelle that acts as a 'package' to transport materials from the Golgi apparatus to the outside of the cell.

Front

What is the plasma membrane and its importance?

Back

The plasma membrane controls what goes into and out of the cell, helping to maintain homeostasis. It is made of lipids and is present in all cells.

Front

What is the nucleus and its role in a cell?

Back

The nucleus is an organelle that holds the DNA and is considered the control center of the cell. Prokaryotic cells do not have a nucleus.

Front

What is DNA and its significance in cells?

Back

DNA is the genetic material found inside cells, containing the instructions for the development and functioning of living organisms.

Front

What is the function of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, where energy (ATP) is produced through cellular respiration.

Front

What is the role of lysosomes in a cell?

Back

Lysosomes are organelles that contain enzymes to break down waste materials and cellular debris.

Front

What is the function of the cell wall?

Back

The cell wall provides structural support and protection to plant cells, fungi, and some bacteria, but is not found in animal cells.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

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 it also helps in the transport of materials within the cell.
