Photosynthesis is the process by which living things collect and store energy, and respiration is the process by which living things release that store energy to perform work. The chemical reaction of photosynthesis is t... More » Science Human Anatomy Organs

Photosynthesis is the process where a plant consumes water, carbon dioxide and light energy to produce glucose and oxygen. During cellular respiration, the chemical energy in the glucose molecule converts into a form the... More » Science Biology Cells

Plants do perform cellular respiration. Plants produce energy through both photosynthesis and respiration. However, photosynthesis requires sunlight, so plants respire both day and night in order for their cells to have ... More » Science Biology Botany

During the process of respiration, gases like oxygen are ingested and chemically broken down, or oxidized, to provide energy for the living organism. This process ends with the expulsion of a different gas or byproduct o... More » Science Human Anatomy Organs

Photosynthesis is a process that allows plants to harvest energy in sunlight and store it chemically, by producing sugars. Sugars hold energy in their molecular bonds; when the plant breaks down these bonds, energy is re... More » Science Biology

In prokaryotic cells, respiration occurs in the cytoplasm; in eukaryotic cells, the process begins in the cytoplasm but a majority of the chemical reactions occur in the mitochondria. Respiration is the process of releas... More » Science Human Anatomy Organs

Photosynthesis, the process by which plants convert the sun's energy to glucose, takes place during daylight hours when the plant's leaves are exposed to sunlight. This process only occurs in green plants and in some pro... More » Science Biology Botany
