The two main multi-subunit membrane protein complexes differ in their absorbing wavelength, where the photosystem I or PS 1 absorbs the longer wavelength of light which is 700 nm while photosystem II or PS 2 absorbs the shorter wavelength of light 680 nm. Secondly, each photosystem is replenished by the electrons, after the loss of an electron, but the sources are different where PS II gets it electrons from water while PS I gains electrons from the PS II through an electron transport … [Read more...]

The part of the plant which is present above the surface of the soil is called Stems, while Roots is the part of the plant which is present below the soil surface. Secondly stems arises from the plumule and roots from the radical of the embryo. Most importantly stems possess leaves, but roots do not. A common flowering plant (vascular plants) possess a well-defined root and shoot system. These are an essential part of the plant and bears many morphological and anatomical differences. Though … [Read more...]

Vascular plants or tracheophytes are known for their proper organization of the systems, and bearing flowers, green leaves, stems, roots, woods, and branches, on the contrary, Non-vascular plants or bryophytes do not perfectly fit with these features. Examples of Conifers, Ferns, flowering, and non-flowering plants are examples of vascular plants, while Mosses, Liverworts, and Hornworts are examples of non-vascular plants. But most importantly the difference lies in the presence of the … [Read more...]

Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage. Collenchyma cells are known for providing mechanical support to the plants, by protecting the delicate inner part of the plant. Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant. Likewise the humans, who have bones to support their body structure, plants also have certain specialized tissues which help them, by providing … [Read more...]

The process of transfers of pollen grains from anthers to the stigma of a flower, but when this process is between the flowers of the same plant than the term is called as self-pollination, while when the transfers are between the flowers of the different plant of same species is called as cross-pollination. Secondly, pure line progeny is obtained in the self-pollination. The target of every living organisms is to create their young ones and transfer their characters to them. Pollination is … [Read more...]

By comparing the typical examples of the plants and trees like Mango, Guava and Rose, Coriander, we will able to differentiate the simple, and the compound leaves easily. As in simple leaves, there is only single leaf blade and incision, which are so light that does not divide the leaf blade, but in compound leaves the incision is so deep that the leaf blades are divided into leaflets. Each one of us is aware of the importance of plants in an atmosphere as well as for living beings. Even the … [Read more...]

Cellular respiration takes place in the every living organisms, as it is the simple process of converting oxygen and glucose into carbon dioxide and water and ultimately producing energy for the cells of the body. On the contrary, photosynthesis occurs in green plants, which contain chlorophyll and uses sunlight and water to convert it into energy. These are the two reciprocal process, with the same aim of obtaining energy but by using different methods, different sources and thus giving out … [Read more...]

In a plant, the veins of the leaf blade or lamina exhibiting the parallel pattern from the base to the tip is known as the parallel venation, on the contrary, when the veins of the leaf blade or lamina in the plants exhibit the web like or net-like pattern on both side of the midrib is known as the reticulate venation. In a leaf, the arrangement of veins is called as venation. The venation architecture is enormously distributed among the diverse species of the plants. The venation has its … [Read more...]

Mitochondria are known for generating energy for the cell in the form of ATP (adenosine triphosphate) by using nutrients and oxygen. The chloroplast is present in green plants and few algae, they are known as the place, where the process of photosynthesis occurs. In the cell of the eukaryotes, there are only three organelles, which are bounded by the double membrane structure - the nucleus, the mitochondria, and the chloroplast. There is the higher level of diversity on the surface of the … [Read more...]
