Chloroplasts are the sites of photosynthesis in plants

Some parts of the flower are directly involved in fertilization and seed production.

is both a reactant &product of photosynthesis

It is evident from these absorption and output plots that only the red and blue ends of the part of the are used by plants in photosynthesis. The reflection and transmission of the middle of the spectrum gives the leaves their green visual color.

The following equation sums up the photosynthesis reaction:

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.


Through the process of photosynthesis, sun light is absorbed by plants and converted into chemical energy. Using that chemical energy, the plants are then able to absorb carbon dioxide from the atmosphere and turn it into food for themselves. A beneficial byproduct of that food production is oxygen, which humans need in order to breathe. Photosynthesis will occur in plants, algaes, and different species of bacteria, and organisms that can perform photosynthesis are referred to as photoautotrophs, meaning they can create their own food. Photosynthesis is vital to life on Earth as it helps maintain normal levels of oxygen in the air which is necessary for survival of most species.


Plants make their own food thru the process of photosynthesis

Animals eat food to get their energy. But green plants don't. Instead they make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise.

Do all parts of plants carry out photosynthesis? - Quora

In leafy plants, the process of photosynthesis occurs largely in the leaves. Because of this, all the necessary ingredients need to be present in the leaves for the reaction to take place. Carbon dioxide is absorbed into the leaves from the air, water is routed from the roots to the leaves, and sunlight is absorbed into the leaves through chlorophyll. Chlorophyll is a green pigment inside plant cells called chloroplasts - which also have several other structures within them. Chloroplasts are important because they are where photosynthesis takes place.

Photosynthesis can be carried out by any green parts of the plant

Current understanding is that the earliest photosynthetic organisms were aquatic bacteria, some of which are still around today. One of these, halobacterium halobium, grows in extremely salty water. It makes use of the bacteriorhodopsin pigment. The chlorophyll system developed to use the available light, as if it developed in strata below the purple bacteria and had to use what it could get.

Effect of light intensity on photosynthesis ..

But what about the development of land plants? Why did they stay green? The thoughts are that they had plenty of light and were not pressured to develop more efficient light gathering. That is, the light was not the limiting resource in photosynthesis for plants.

Comparative photosynthesis of sun and shade plants.

Photosynthesis and all associated reactions take place at the molecular level. These microscopic reactions involve several molecules aside from chlorophyll. Some of the other molecules are water (H2O), carbon dioxide (CO2), oxygen (O2), and glucose (C6H12O6). All of the components are necessary and the absence of any one of them causes the entire process to fail. For example, if there is no water available to the plant roots, they will begin to turn brown and die, effectively stopping photosynthesis. Oxygen and glucose are not used in photosynthesis, but are byproducts of the reaction. Oxygen is released into the air, and glucose is stored inside the plant cells.
