8D - Unicellular Organisms

Which of these is a 'life process' carried out by all organisms?

• photosynthesis
• breathing
• fermentation
• respiration

Two kingdoms that contain many unicellular microorganisms are:

• prokaryotes and protoctists.
• animals and plants.
• yeast and fungi.
• viruses and bacteria.

Multicellular organisms need transport systems to carry materials to their cells because:

• diffusion is not fast enough to do this.
• diffraction is not fast enough to do this.
• dissolving is not fast enough to do this.
• dispersion is not fast enough to do this.
