In plant cells, chloroplasts perform photosynthesis, a process that converts light energy from the sun into chemical energy in the form of glucose. Plants can later use this stored chemical energy to carry out activities... More »

Plants use chlorophyll, a green pigment responsible for the color of most plants, to absorb light and produce usable chemical energy through photosynthesis. Carbohydrate molecules are created from water and carbon dioxid... More »

Earth's atmosphere has gone through multiple distinct phases throughout its life, from a hydrogen-rich early period to the modern oxidizing chemistry. The first atmosphere Earth had was chemically very similar to the com... More »

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 »

The mesophyll cells in a plant leaf play a vital role in photosynthesis by enabling the gas exchange portion of the process, and through the actions of their specialized chlorophyll-containing organelles, called chloropl... More »

The primary function of the palisade layer of a leaf is to host most of the chloroplasts in the plant, which is where photosynthesis occurs. The palisade layer is a collection of cylindrical-shaped cells just beneath the... 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 »
