For that reason, chlorophyll a is the most efficient and important pigment involved in photosynthesis. Our results are consistent with those of Nazar et al. There are several kinds of chlorophyll, the most important being chlorophyll "a". The chloroplast, an oval-shaped structure, is divided by membranes into numerous disk-shaped compartments. The thickness of palisade mesophyll has been found to be positively correlated with net photosynthetic rate [ 21 ]. Photosynthesis occurs primarily in the mesophyll, which is the middle layer of a leaf. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. The mesophyll contains cells called chloroplasts, which convert sunlight into a stable chemical energy source the plant can utilize. A leaf may be viewed as a solar collector crammed full of photosynthetic cells. It is also called primary photosynthetic pigment because it performs primary reaction of photosynthesis which involves conversion of light into chemical or elec­trical energy. In previous studies, vegetation indices (VIs) have been demonstrated to monitor LNC non-destructively, but which is influenced by backgrounds, and lacks specificity for nitrogen stress. The leaves of grasses, reeds, and sedges have guard cells shaped like _____. We found that, of the three SA treatments, SA1.0 was most effective in increasing leaf photosynthesis under salt stress. The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf. Which part of a leaf's tissue is specialized for light capture and is the main site of photosynthesis in the leaf? [ 28 ], who found that a foliar spray of 1.0 mM SA concentration mitigated the salt-induced reduction in leaf photosynthesis for two mung bean cultivars. One plant leaf is composed of tens of thousands of cells, and each cell contains 40 to 50 chloroplasts. WHERE PHOTOSYNTHESIS OCCURS Plant photosynthesis occurs in leaves and green stems within specialized cell structures called chloroplasts. Its name is derived from the Greek words χλωρός, khloros ("pale green") and φύλλον, phyllon ("leaf"). Chlorophyll (also chlorophyl) is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Leaf nitrogen content (LNC), an indicator for the amount of photosynthetic proteins, plays an important role to understand plant function and status. The main function of a leaf is to produce food for the plant by photosynthesis. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll "a". Among the leaf anatomical traits, palisade tissue might be the most important to photosynthesis because palisade mesophyll cells are the structural powerhouse of photosynthesis. Palisade Mesophyll. The two most common types of chlorophyll are chlorophyll a, which is a blue-black ester with the chemical formula C 55 H 72 MgN 4 O 5, and chlorophyll b, which is a dark green ester with the formula C 55 H 70 MgN 4 O 6.Other forms of chlorophyll include chlorophyll c1, c2, d, and f. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Hence, it is termed as universal photosynthetic pigment. Chlorophyll a absorbs protons and facilitates the transfer of light energy into food energy with help from accessory pigments, such as chlorophyll b, a molecule with many similar characteristics. Chlorophyll is the name given to a group of green pigment molecules found in plants, algae, and cyanobacteria. Chlorophyll a is found in all photo­synthetic plants except bacteria.
