The difference between light reaction and the dark reaction is mainly due to the following properties: The demand for light: A light reaction demands a source of light energy for breaking down water into oxygen, while a dark reaction does not need a light source. Site of occurrence: A light reaction occurs within the thylakoid […]

Chlorophyll in plants refers to a pigment molecule that imparts a green colour to the leaves and stems by absorbing a red and blue spectrum of light. The term chlorophyll has originated from the Greek terms “Khloros” (green) and “Phyllon” (leaf). It plays a fundamental role in photosynthesis by allowing plants to absorb light energy

The difference between root and stem is due to the following properties: Origination: Roots originate from the radicle through the germination of seed, whereas shoots originate from the plumule of the developing embryo. Arrangement of vascular bundles: In roots, the vascular bundles reside within the central core, while shoots have dispersed vascular bundles. Presence of

Chloroplast in a plant cell exists as a membrane-bound cell organelle and contain chlorophyll pigments that are absent in the animal cells. The study of chloroplast was first carried by a scientist named Hugo Von Mohl in the year 1837. After his study, it was found that the chloroplasts were the type of plastids and

The difference between chlorophyll and chloroplast is due to the following factors like location and involvement in photosynthesis. Existence: Chlorophylls exist as the primary photosynthetic pigments inside the chloroplast. Conversely, chloroplasts exist as the photosynthetic cell organelles in a plant cell and possess a membranous structure that resembles mitochondria. Involvement in photosynthesis: Chlorophyll mainly absorbs

The root system remains subterranean or underground the soil in the case of vascular plants. Therefore, it provides strength and rigidity to the growing shoot system against adverse conditions. Some of the trees (like a banyan tree, bonsai tree etc.) have their root system over the ground that refers to aerial roots. Unlike stems, roots

Stomata in plants appear as minute pores, primarily in the epidermis layer of the leaf surface and rarely in some of the herbaceous stems. It was originated from the Greek word stoma (means mouth) to relate it with the term “stomatal pore”. A stoma is a singular form, whereas a high number of stoma is termed

Transpiration in plants is a process of water loss (in the form of water vapours) into the atmosphere from the leaf surface and stems. Plants undergo transpiration primarily to access carbon dioxide needed for photosynthesis and to cool themselves. As the plants are immobile, they manage their water needs by the two fundamental processes like
