During photosynthesis, plants take in water and carbon dioxide and absorb light energy. Plants use the light energy captured by chlorophyll to help form glucose molecules. Glucose molecules store energy.To use this energy,a plant cell needs its mitochondria to break down the glucose.This process of breaking down food molecules to get energy is called cellular respiration.During cellular respiration,cells use oxygen to break down food molecules.Like all cells, plant cells then use the energy from food to do work

Inside our body, millions of nephrons in the kidney filter wastes in 2 steps. Each nephron has a glomerulus and a tubule. Waste filtering undergoes 2 steps:
First, fluid and waste pass through the glomerulus but, proteins, blood cells, and other large molecules are prevented from passing through. Second, the filtered fluid passes through the tubule wherein the filtered wastes are removed; minerals are sent back to the body, and the remaining output becomes urine.
