How Do Plants Make Food? How Photosynthesis Works?

Answer 1

# n plants, photosynthesis is used to convert light energy from sunlight into chemical energy (glucose). Carbon dioxide, water, and light are used to make glucose, oxygen, and water.
# Photosynthesis is not a single chemical reaction, but rather a set of chemical reactions. The overall reaction is:
6CO2 + 12H2O + light -> C6H12O6 + 6O2 + 6H2O
# The reactions of photosynthesis can be categorized as light-dependent reactions and dark reactions.
# Chlorophyll is a key molecule for photosynthesis, though other cartenoid pigments also participate.

# There are four (4) types of chlorophyll: a, b, c, and d. Although we normally think of plants as having chlorophyll and performing photosynthesis, many microorganisms use this molecule, including some prokaryotic cells. In plants, chlorophyll is found in a special structure, which is called a chloroplast.
# The reactions for photosynthesis take place in different areas of the chloroplast. The chloroplast has three membranes (inner, outer, thylakoid) and is divided into three compartments (stroma, thylakoid space, inter-membrane space). Dark reactions occur in the stroma. Light reactions occur the thylakoid membranes.
# There is more than one form of photosynthesis. In addition, other organisms convert energy into food using non-photosynthetic reactions (e.g. lithotroph and methanogen bacteria)..

Answer 2

Plants make food by the process of photosynthesis
In plant cell there is a pigment called chlorophyll which helps in photosynthesis

Answer 3

plants make food by the process of photo synthesis.
Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of glucose from sunlight, carbon dioxide and water, with oxygen as a waste product.

Photosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows.[1]




6 CO2(gas) + 6 H2O(liquid) + photons → C6H12O6(aqueous) + 6 O2(gas)
carbon dioxide + water + light energy → glucose + oxygen
Photosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of glucose.

In the light-dependent reactions one molecule of the pigment chlorophyll absorbs one photon and loses one electron. This electron excites pheophytin allowing the start of a flow of electrons down an electron transport chain that leads to the ultimate reduction of NADP into NADPH. In addition, it serves to create a proton gradient across the chloroplast membrane; its dissipation is used by ATP Synthase for the concomitant synthesis of ATP. The chlorophyll molecule regains the lost electron by taking one from a water molecule through a process called photolysis, that releases oxygen gas as a waste product.

In the Light-independent or dark reactions the enzyme RuBisCO captures CO2 from the atmosphere and in a process that requires the newly formed NADPH, called the Calvin-Benson cycle releases three-carbon sugars which are later combined to form glucose.

Photosynthesis may simply be defined as the conversion of light energy into chemical energy by living organisms. It is affected by its surroundings and the rate of photosynthesis is affected by the concentration of carbon dioxide, light intensity and the temperature.

Answer 4

flora receives their foodstuff by an progressed procedure called photosynthesis by ability of replacing photograph voltaic to sugar.. it receives switched over in the chloroplast... i'm in center college.. desire this helps.

Answer 5

photosyntthesis is known as that the plant makes their food is presence of sun rays and water in earth.
