Chloroplasts are the site of photosynthesis in green plants

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.


how a chloroplast is specialised for photosynthesis?

The leaves are the principal organs in which the process of chlorophyll photosynthesis takes place.

In plants, epidermal cells do not contain chloroplasts (with the exception of guard cells) and so do not photosynthesise.

This process is called photosynthesis. Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis.

Cyanobacteria and plants use photosynthesis to make their own fuel from nothing more than CO2, water, and the sun's rays. Artificial photosynthesis is therefore any process that attempts to mimic nature by chemically storing solar energy inside of a fuel. Artificial photosynthesis also includes any technologies that attempts to replicate any part of the photosynthetic process. The term is often used to describe a variety of technologies, including the photocatalytic splitting of water into hydrogen fuel and oxygen gas, the use of photosynthetic microorganisms for biofuels, or the complete biomimicry of the photosynthetic reaction process to create chemical fuels.

Animals and plants are made of cells

2.4 billion years ago, photosynthetic cyanobacteria, or blue green algae as they are sometimes erroneously called, terraformed our planet into the habitable oasis we have come to call Earth. They absorbed sunlight and carbon dioxide and released oxygen transforming Earth's reducing atmosphere into an oxidative one, shifting the balance of life in favor of more complex oxygen loving organisms like ourselves. Today, another organism is poised to shift that balance in the opposite direction. Humans and their penchant for burning fossil fuels have already unloaded an unprecedented amount of CO2 into the Earth's atmosphere. Since it was photosynthesis that instigated the climate change that gave our ancient aerobic ancestors a chance in the past, it is probably fitting that a little biomimicry could solve the climate and energy woes of today.

C4 photosynthesis incorporates novel leaf anatomy, metabolic specialisations and modified gene expression. C4 plants typically possess a distinctive Kranz leaf anatomy consisting of two photosynthetic cell types. These are bundle sheath (BS) cells that surround the vascular centres, and mesophyll (M) cells that, in turn, surround the BS cells. A more rare form uses compartmentalisation of dimorphic chloroplasts within a single cell type. In C4 leaves, these structural frameworks functionally separate two sets of carboxylation and decarboxylation reactions. Selective expression of key photosynthesis genes in BS and M cells leads to specific accumulation of key photosynthetic enzymes which catalyse different sets of cell‐type‐specific reactions, enabling these plants to assimilate atmospheric CO2 with very high efficiency. For some plants, C4 photosynthesis has facilitated their adaptation to arid conditions, high temperatures and marginal environments. Understanding the basis of this pathway has applications for improvements in agricultural productivity and alternative fuel development.
