Foundations of Biology

What is the function of the cell membrane?

• Stores energy for the cell

• Helps the cell move around

• Provides color to the cell

• Regulates what enters and leaves the cell, provides protection and support, and allows for cell communication.

Which organelle is responsible for protein synthesis?

• ribosome

• endoplasmic reticulum

• nucleus

• mitochondria

What is the function of the mitochondria?

• Producing energy through cellular respiration

• Storing genetic material

• Producing glucose through photosynthesis

• Regulating cell division

What is the main function of the nucleus?

• Produce energy for the cell

• Synthesize proteins for the cell

• Regulate cell shape and movement

• Control cell activities and store genetic material

What is the function of the Golgi apparatus?

• Storing genetic information

• Regulating cell growth

• Producing energy for the cell

• Modifying, sorting, and packaging proteins and lipids

What is passive transport in cells?

• The process of cell division

• Movement of substances across cell membranes without the need for energy input

• Movement of substances across cell membranes with the need for energy input

• Transport of substances within the cell nucleus

Give an example of passive transport in cells.

• Diffusion

• Active transport

• Osmosis

• Endocytosis

What is active transport in cells?

• The movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

• The movement of molecules across a cell membrane through osmosis.

• The movement of molecules across a cell membrane without the use of energy.

• The movement of molecules across a cell membrane from a region of higher concentration to a region of lower concentration, requiring energy.

Give an example of active transport in cells.

• Facilitated diffusion

• Sodium-potassium pump

• Osmosis

• Simple diffusion

What is the function of the endoplasmic reticulum?

• Storage of genetic material

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

• Regulation of cell division

• Energy production in the cell
