- A Quick Look at Phytoremediation. Phytoremediation is the direct use of living green plants for in situ, or in place, removal, degradation, or containment of contaminants in soils, sludges, sediments, surface water and groundwater. Phytoremediation is: 1  A low cost, solar energy driven cleanup technique.

Exocytosis: Definition & Examples Exocytosis Definition. Exocytosis is a process by which a cell transports secretory products through the cytoplasm to the plasma membrane.Secretory products are packaged into transport vesicles (membrane-bound spheres).nstead, fusion with the plasma membrane and secretion of vesicle contents into the extracellular environment happens automatically. This constant flow of secretory product is also called constitutive exocytosis because secretion from the vesicles is not controlled. The first figure illustrates the differences.

Flocculation refers to the separation of a solution and most commonly, this word is used to describe the removal of a sediment from a fluid. In addition to occurring naturally, it can also be forced through agitation or the addition of flocculating agents.

deforestation Deforestation is the clearing of trees, transforming a forest into cleared land. The first step in turning the wilderness into a shopping center is deforestation. You can see the word forest in deforestation. The prefix de- means remove and the suffix -ation signals the act or state of. So deforestation is the act of removing a forest. First, the trees are chopped down, the wood shipped around the world for making products. Then the land is made smooth enough for homes, businesses, or farming. Today, in many places, laws limit the amount of deforestation.

What is phagocytosis? what is pinocytosis? PINOCYTOSIS In cellular biology, pinocytosis (cell-drinking) is a form of endocytosis, a process in which small particles are taken in by a cell by splitting into smaller particles. The particles then form small vesicles which subsequently fuse with lysosomes to hydrolyze, or to break down, the particles.inocytosis is primarily used for the absorption of extracellular fluids (ECF), and in contrast to phagocytosis, generates very small vesicles. Unlike receptor-mediated endocytosis, pinocytosis is unspecific in the substances that it transports. The cell takes in surrounding fluids, including all solutes present.

- Efferent arterioles of glomeruli in the outer cortex form the peritubular plexus which surrounds proximal and distal tubules. Efferent arterioles of glomeruli in the deeper cortex contribute to the adjacent peritubular plexus and also form the vasa recta which accompany the loop of Henle into the medulla.

What is bioremediation? Bioremediation. Remediate means to solve a problem, and bio-remediate means to use biological organisms to solve an environmental problem such as contaminated soil or groundwater. In a non-polluted environment, bacteria, fungi, protists, and other microorganisms are constantly at work breaking down organic matter.

Difference between Pinocytosis and Phagocytosis Pinocytosis is the absorption of liquids, whereas phagocytosis is the absorption of solid objects which are essentially food for the cell. Almost all cells perform pinocytosis, however phagocytosis is performed only by specialized cells that protect tissues by engulfing bacteria, cell debris, and other abnormal materials.
