Respiration, in which energy is released from carbohydrates for metabolic needs, takes place in plants through a process which can be expressed in a word equation as: glucose + oxygen = energy + carbon dioxide + water. T... More »

During photosynthesis, light energy is converted into chemical energy. The energy is stored in carbohydrate molecules including glucose and starch. More »

Guard cells line the openings of stoma and other organs in plants, opening and closing to moderate the process of respiration. The chief role of guard cells is to prevent an excess loss of water through respiration, allo... More »

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 »

Totipotency refers to a developmental flexibility within plant cells that distinguish them from most animal cells, in that many somatic plant cells can regenerate into entire plants. Two researchers in the 1950s were the... More »

Cellulose makes up most of the tough cell walls surrounding plant cells and enables plants to stand upright, according to Education Portal. It is the major component of plants that makes the branches, stems and leaves ve... More »
