Which of the following is the basic structural unit of all living organisms?

• Tissue

• Organ

• Cell

• Organism

Genetic material can be found in what organelle?

• the golgi complex

• the mitochondria

• the nucleus

• the chloroplasts

Stores carbohydrate in the form of glycogen.

• Animal cells

• Plant cells

The illustration shows the movement of substances from blood capillary into a body cell.

Which factor causes the substances to move into the body cell?

• Metabolic energy

• Concentration gradient

• The presence of a completely permeable membrane

• The presence of a cell membrane

The head of a phospholipid is attracted to water, and is referred to as:

• Hydroscopic

• Hydrogenated

• hydrophobic

• Hydrophilic

The diagram shows the movement of molecule P across the plasma membrane through process R with the help of protein molecule.

Choose the statement that is not corresponding with process R or molecule P.

• Process R occurs against the concentration gradient.

• Process R does not need energy to happen.

• Molecule P is most probably glucose molecule as it cannot pass through the phospholipid bilayer directly.

• The movement of molecule P is caused by kinetic energy within the particles itself.

What might happen if a cell did not have any ATP/energy?

• It would not have enough energy to do active transport

• It's cell membrane would break

• The transport proteins would not be needed.

• Diffusion

• Active Transport
