During photosynthesis, the light-dependent phase only takes place in the presence of light and the dark phase, also known as the light-independent phase, only takes place in the absence of light.

• True

• False

Which of the following is not an example of a way in which ATP is used? 

• • ATP provides energy for the beating of cilia and flagella, which are the hair-like organelles found in some microorganisms that help with movement or mobility.

• • ATP is used for the breaking down of macromolecules such as nucleic acids, proteins and fats. 

• • ATP is used for active transport or movement of substances across cell membranes. 

• • ATP is used in animals for the contraction of muscle cells.

With low levels of light, a plant cannot photosynthesise, even if there is plenty of water and carbon dioxide available.
