The pyramid of biomass in sea is generally inverted because the biomass of fishes far exceeds that of phytoplankton. Isn’t that a paradox? How would you explain this
Concept/Reason Explanation Standing Crop The standing crop refers to the total biomass of organisms (like phytoplankton) present in an ecosystem at a given moment. In marine ecosystems, the standing crop of phytoplankton is small, but this doesn’t limit their ability to support consumers. Turnover Rate Turnover rate refers to how quickly organisms (like phytoplankton) are
When we say that parenchyma cells are generally isodiametric
Parenchyma Cells – Isodiametric Nature The Cells of the Parenchyma are Generally Isodiametric. Why? When we talk about parenchyma cells, a common description is that they are isodiametric—meaning that their dimensions (length, width, and height) are more or less equal. But why are these cells structured this way, and what purpose does it serve? What

NCERT-As traditional breeding techniques failed to keep pace with demand and to provide sufficiently fast and efficient systems for crop improvement,another technology called tissue culture got developed
Traditional Breeding Limitations and the Rise of Tissue Culture Traditional Breeding Limitations and the Rise of Tissue Culture Traditional breeding techniques, while instrumental in agricultural development, often struggle to keep pace with the growing demand for improved crops. To address these limitations, a revolutionary technology called tissue culture emerged in the 1950s. What is Tissue
Explanation of NCERT EXCERPT – on Sclerenchyma
Sclerenchyma consists of long, narrow cells with thick and lignified cell walls having a few or numerous pits. They are usually dead and withoutprotoplasts. On the basis of variation in form, structure, origin and development, sclerenchyma may be either fibres or sclereids. General defination : Sclerechyma Cells: Parenchyma cells that have developed secondary cell walls.
