Compare and contrast the structure and function of the three simple tissue types: parenchyma, collenchyma, and sclerenchyma.

Parenchyma cells refer to plant cells in the leaf that are usually alive at maturity. They have cell walls that are thin and flexible. They generally have a central vacuole that is large. They have a polyhedral arrangement. They are involved in carrying out photosynthesis, storage functions, and other metabolic functions. Most of these cells have the potential to undergo differentiation generating other cell types in certain conditions. For instance, when the plant is injured and there is a need for repairing and replacing organs. Their large central vacuoles enable them to store water, regulate intake of ions and ...

Abstract

The following summary discusses the cooling techniques of atomic vapor in several different ways. Additionally, it tends to relate the evolution of experiments that are used in studying shallow layered fluids. Starting with the atomic condensates, the method is known as trapping. However, it exists in many ways from the laser system to the Bose-Einstein methods. The methods of cooling are different due to the evolutionary progress made by science. The use of laser beams includes the study of light forces on atoms which lead to either an absorption or emission of a photon. While the contraction of matter ...
