What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

Which cell part is NOT found in all cells?

Back

Cell Wall is not found in all cells; it is present in plant cells, fungi, and some bacteria, but absent in animal cells.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts, which contain chlorophyll that captures light energy.

Front

What organelle is unique to plant cells and is involved in storage and maintaining turgor pressure?

Back

Vacuole is unique to plant cells and helps in storage of substances and maintaining turgor pressure.

Front

What is the structure that controls the movement of substances in and out of the cell?

Back

The Cell Membrane is a double layer of phospholipids that controls the movement of substances in and out of the cell.

Front

What is the powerhouse of the cell?

Back

Mitochondria are known as the powerhouse of the cell because they produce ATP through cellular respiration.

Front

What is the role of the nucleus in a cell?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.

Front

What is the function of chloroplasts?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

What is the function of lysosomes?

Back

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

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.
