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.

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.

Osmosis
Diffusion
Active Transport
