Cellular extensions also known as cytoplasmic protrusions and cytoplasmic processes are those structures that project from different cells, in the body, or in other organisms. Many of the extensions are cytoplasmic protrusions such as the axon and dendrite of a neuron , known also as cytoplasmic processes.
Resource availability is essential for the unimpeded growth of a population. Examples of resources organisms use are food, water, shelter, sunlight, and nutrients.[1][2] Ideally, when resources in the habitat are unlimited, each species can fully realize its innate potential to grow in number, as Charles Darwin observed while developing his theory of natural selection.
Convergent extension has been primarily studied in frogs and fish due to their large embryo size and their development outside of a maternal host (in egg clutches in the water, as opposed to in a uterus). [1] Within frogs and fish, however, there exist fundamental differences in how convergent extension is achieved.
Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. [1] Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism).
However, a new study published by scientists at the University of Chicago argues that the increase in human lifespan induced by modern medicine may be reaching its biological limit. In other words ...
For example, enzymes that digest carbohydrates called glycosidases are present at high concentrations on the surface of enterocyte microvilli. Thus, microvilli not only increase the cellular surface area for absorption, they also increase the number of digestive enzymes that can be present on the cell surface.
Cell division, growth, and proliferation. Cell proliferation is the process by which a cell grows and divides to produce two daughter cells. [1] [2] [3] [4] Cell ...
