Plant cells use the sugar molecules produced by photosynthesis for two purposes. Some of the sugar molecules are used to synthesize other organic molecules like amino acids and cellulose so the plant can grow. Other sugar molecules and oxygen are used for to make which provides the energy for many biological processes.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.
