Answer:
reactions
Explanation:
Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.
Similarities: both originated from “protists” and they have similar cell structures.
Differences: plants use photosynthesis to make food, while fungi cannot. Fungi does not possess chlorophyll, which is a key part of the photosynthesis process for plants.
