Which is the main part of the plant that carries out photosynthesis

We have identified that chloroplasts are the site of photosynthesis in plants to convert the light energy into chemical energy by the process of photosynthesis.

In plants, plastidsmay differentiate into several forms, depending upon which functionthey needto play in the cell.

2014 leaf is organ in plant specially for photosynthesis.

· Though all green parts of the plant are capable of performing photosynthesis, the leaves are the most suitable organ of the process. The cells of the leaves contain special organelle called as chloroplasts, which are the main site of photosynthesis. These are the plastids which contain light absorbing green pigments chlorophyll.

Photosynthesis takes place inside plant cells in small things called chloroplasts

· Chloroplast is the site of photosynthesis. A typical chloroplast of higher plants is discoid shaped. It is a double membrane bound organelle containing chlorophyll, carotenoid, xanthophyll, cytochrome, DNA, RNA, Mn etc.

Nucleus: this contains genetic make (the DNA), which controls the activities of the cell.

Chlorophyll absorbs the light energy needed to make photosynthesis happen. It is important to note that not all the color wavelengths of light are absorbed. Plants mostly absorb red and blue wavelengths — they do not absorb light from the green range.

The leaves and stem together form the shoot

Unlike C-3 plants, cacti possess a crassulacean acid metabolism (CAM) physiology that can alter the pattern of carbon uptake and affect plant growth under artificial environmental conditions, especially in tissue culture. In vitro-derived plantlets of Coryphantha minima grew 7-fold larger than plants cultured under similar ex vitro conditions. Growth regulators incorporated into the culture media during shoot proliferation stage of micropropagation had a strong influence on this increased growth. Other important factors that contributed to increased growth under in vitro conditions were high relative humidity and sugar in the culture medium. An analysis of gas exchange and daily fluctuations of malic acid levels revealed an increase in net photosynthetic rate, in terms of carbon assimilation, by in vitro plants compared with that of ex vitro plants. This stimulated photosynthesis in the presence of an external carbon source was unexpected but apparently true for cacti exhibiting CAM physiology. Unlike CAM plants grown in ex vitro conditions, net CO2 uptake by in vitro-cultured cacti occurred continuously in the light as well as the dark. Once regenerated, cacti were transferred to ex vitro conditions where the normal CAM pathway resumed with a concomitant reduction in growth and CO2 uptake. These results showed that growth of cacti can be considerably accelerated by in vitro culture.
