Understanding Cell Structure and Functions - Grade 10 Biology Quiz

Cytoplasm is a jelly-like substance that fills the inside of cells and surrounds the organelles. It plays a crucial role in various cellular processes such as metabolism and provides a medium for the organelles to function within the cell.

The nucleus serves as the command centre of the cell, containing genetic information and controlling cell activities.

The cell wall is responsible for providing structural support and protection to the cell by surrounding the cell membrane and maintaining the cell's shape. It also helps regulate the osmotic pressure of the cell and prevents it from bursting or collapsing.

The nucleolus is a suborganelle within the nucleus of a cell that is primarily involved in producing ribosomes, not energy production, DNA storage, or waste breakdown.

Plant cells have unique structures like the cell wall, chloroplast, and vacuole which are not found in animal cells. The incorrect answers, nucleus, mitochondria, and lysosome, are found in both plant and animal cells.

Centrosomes are only found in animal cells and play a role in cell division.

The cell membrane primarily acts as a barrier to control the movement of molecules in and out of the cell, maintaining homeostasis.
