Difference Between Chlorophyll and Chloroplast

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 …

Stomata in Plants

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

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 …

Respiration in Plants

Respiration in plants refers to a process in which a plant utilizes atmospheric oxygen to oxidize glucose and other respiratory substrates like fats or proteins. Respiratory substrates are high energy biomolecules that produce energy, carbon dioxide, and water due to the C-C bond breaks. Plants undergo cellular respiration in the presence or absence of light. …

Germination of Plant

Germination of a plant refers to a phenomenon in which a seed germinates to form a new seeding or plant. The germination process results in the emergence of the radicle (primary root) and plumule (primary shoot). Before germination, the seed remains dormant in the soil. Then, under favourable conditions (optimum temperature, oxygen, light, water etc.), a …

Anther

The anther is a part of the flower’s male reproductive system or stamen. It carries the reproductive structures or the male gametes (pollen grains), which germinate and cause the fertilization of an ovule. A male reproductive part of a flower typically consists of two elements (filament and anther). A filament appears as a long, slender …
