Biology 8th Grade: Cell Structure and Function

What is the basic unit of life?

• cell

• atom

• organism

• molecule

Name the organelle known as the 'powerhouse' of the cell.

• nucleus

• endoplasmic reticulum

• ribosomes

• mitochondria

What is the function of the cell membrane?

• Produce proteins for the cell

• Store energy for the cell

• Regulate what enters and leaves the cell, provide protection and support, and allow for cell communication.

• Regulate temperature within the cell

What is the function of the nucleus in a cell?

• Control center of the cell

• Waste storage

• Energy production

• Cell wall formation

Name the organelle responsible for protein synthesis.

• chloroplast

• ribosome

• mitochondria

• nucleus

What is the function of the mitochondria in a cell?

• Produces energy through cellular respiration

• Produces glucose through photosynthesis

• Regulates cell division

• Stores genetic information

What is the difference between plant and animal cells?

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

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

• Plant cells have a cell wall and chloroplasts, while animal cells do not.

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

What is the function of the endoplasmic reticulum in a cell?

• Energy production in the cell

• Regulation of cell division

• Protein and lipid synthesis, and transportation of molecules within the cell

• Storage of genetic material

What is the function of the Golgi apparatus in a cell?

• Storing genetic information

• Regulating cell division

• Modifying, sorting, and packaging proteins and lipids

• Generating energy for the cell

Explain the process of osmosis in a cell.

• Osmosis is the movement of oxygen molecules into the cell

• Water molecules move from an area of higher concentration to an area of lower concentration

• Water molecules move from an area of lower concentration to an area of higher concentration

• Osmosis only occurs in plant cells, not animal cells
