SCIENCE FORM 1 - 2.1 CELL-STRUCTURE, FUNCTIONS AND ORGANISATION

What is the basic unit of all living organisms?

• cell

• molecule

• tissue

• organ

Which organelle is known as the powerhouse of the cell?

• nucleus

• ribosomes

• mitochondria

• lysosomes

What is the function of the cell membrane?

• Provides energy to the cell

• Regulates cell division

• Stores genetic information

• Controls the movement of substances in and out of the cell

What is the main function of the nucleus in a cell?

• Control gene expression and regulate cell activities

• Store nutrients and provide structural support

• Synthesize proteins

• Facilitate cell division

What is the function of the chloroplast in plant cells?

• Water absorption

• Photosynthesis

• Cell division

• Cell respiration

What is the function of the mitochondria in a cell?

• Produces energy (ATP) through cellular respiration

• Synthesizes proteins

• Stores genetic material

• Regulates cell division

What is the difference between plant and animal cells?

• Plant cells have a nucleus, while animal cells do not.

• Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells have centrioles.

• Plant cells have flagella for movement, while animal cells do not.

• Animal cells have a cell wall, while plant cells do not.

Which type of cell has a cell wall: plant cell or animal cell?

• virus cell

• fungi cell

• bacteria cell

• plant cell

What is the function of the cytoplasm in a cell?

• Storage of genetic material

• Site for cellular activities

• Production of energy

• Regulation of cell division

What is the function of the vacuole in plant cells?

• Cell division

• Storage of water, nutrients, and waste products; maintenance of turgor pressure; structural support

• Protein synthesis

• Photosynthesis
