Exocytosis is a means of membrane transportation that expels the intracellular material out of the cell. The transport of the substance is mediated by the vesicles that eliminate the cell debris and releases specific proteins, enzymes, hormones etc. outside the cell. It is a type of active transport mechanism that makes the use of ATP. …
Cheese production also refers to as “Caseiculture”. It makes the use of raw materials, bacterial culture along with rennet to process the end-product, i.e. cheese. Cheese comes in different varieties by the difference in ingredients and the processing of cheese. Cheesemaking can accomplish by using milk, either in a raw or pasteurized form. Depending upon …
Mesophytes represent the group of plants that can neither grow in the complete aquatic habitat nor the scarcity of water or dry conditions. These are the land plants that show features similar to both hydrophytes and xerophytes. These grow under favourable conditions, where the concentration of water and temperature are not too much high and …
Adaptations in hydrophyte are of three kinds, ecological, physiological and anatomical. For the survival in an aquatic habitat, hydrophytes modify its structures like leaves, stem, roots and the physiology of the cells to adapt themselves according to the different aquatic habitats like freshwater, marine water, lakes, ponds etc. The adaptations in hydrophyte depend upon the …
Hydrophytes represent a group of plants that are the part of the aquatic ecosystem, where most of the plants live in water or the soil saturated with water. The higher plants of hydrophytes have been evolved from the mesophytes. These sometimes refer as “Macrophytes” and are the common components of wetland. These plants live in …
Difference between hypogynous and epigynous flower is mainly due to the following factors, namely the position of an ovary and attachment of perianth and androecium. Position of the ovary: An ovary is a flower’s female reproductive structure that constitutes Gynoecium along with stigma and style. A hypogynous flower consists of a superior ovary, whereas epigynous flower …

Corolla in plants is a second whorl that completes the perianth together with the layer of the calyx. It generally comprises several petals whose primary function is similar to the role of calyx that is to protect the flower reproductive structures. Corolla is also a sterile part of the flower. It can be tubular, funnel-shaped, wheel-shaped …
Calyx in plants merely refers as an outermost whorl that is sterile or non-reproductive structure constituting perianth. Group of sepals unitedly refer as the calyx. Thus, sepals are nothing but the modified leaves that account for the formation of the flower’s outermost whorl. It can be regular or irregular in size and shape, and the …
Phytochrome in plants is a soluble protein pigment that carry out photomorphogenic growth. It is present almost in all eukaryotic plants and was first discovered by a scientist named Sterling Hendricks and Herry Borthwick in the year 1940-1960. A term phytochrome was also given by Warren Butler. In the year 1983, Peter and Clark were …
Photoperiodism can merely define as the potential of the plant to incite flowering relative to the changes in the photoperiod. Thus, photoperiod is a light duration or the length of day and night, while the photoperiodism is the effect of light duration in the growth of a plant. Depending upon the photoperiodic effect on flowering, the …
