What is the function of ribosomes in a cell?

• To store genetic information

• The function of ribosomes in a cell is to make proteins.

• To generate energy for cellular processes

• To transport nutrients within the cell

How do plant cells differ from animal cells in terms of shape?

• Plant cells have a rigid, rectangular shape and a cell wall. Animal cells have varied, often round shapes and no cell wall.

• Plant cells are round and flexible; animal cells are rigid and rectangular.

• Plant cells are oval-shaped; animal cells are square-shaped.

• Both plant and animal cells have the same irregular shape.

What is the main function of the cell membrane?

• To synthesize proteins.

• The main function of the cell membrane is to control the movement of substances in and out of the cell.

• To provide energy for cellular processes.

• To store genetic information.

What is the function of the vacuole in plant cells?

• The vacuole stores substances and maintains turgor pressure in plant cells.

• The vacuole helps in cell division.

• The vacuole is responsible for photosynthesis.

• The vacuole produces energy for the cell.
