An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.

Here, the areolar tissue is located underneath the epithelial tissue. The main functions of areolar tissue are to support the organs present in the abdominal cavity, filling the space between muscle fibres, wraps around blood and lymph vessels as a protective layer etc. They also help organs to resist stretching and tearing forces

Stomata must open to allow the gas exchange of carbon dioxide and oxygen for efficient photosynthesis (see Photorespiration ), and light thus typically triggers stomatal opening. When stomata are open, however, water vapor is lost to the external environment, increasing the rate of transpiration.

In Excel got functions? No? You need the insert function dialog box. How do you get it? When you want to insert a blank imbedded excel object in a word document you can Got functions? No? You need the insert function dialog box. How do you get it? What do we call a computer program that organizes data in rows and columns of cells?

In this article we will discuss about:- 1. Meaning of Mitochondria 2. Shape and Size of Mitochondria 3. Structure 4. Autonomy 5. Functions. Meaning of Mitochondria: Mitochondria are cell organelles of aerobic eukaryotes which take part in oxidative phosphorylation and Krebs cycle of aerobic respiration.

Vacuole (plants) Quick look: A vacuole is a membrane-enclosed fluid filled sac found in the cells of plants including fungi. Vacuoles can be large organelles occupying between 30% and 90% of a cell by volume. Vacuoles appear to have three main functions, they: contribute to the rigidity of the plant using water to develop hydrostatic pressure.

chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.

Introduction. Mitochondria are integral to normal cellular function as they are responsible for energy production in eukaryotes, including the synthesis of phospholipids and heme, calcium homeostasis, apoptotic activation and cell death. 1,2 Alterations in mitochondrial function often associate with disease states including endocrine related disorders such as diabetes mellitus, reflecting the.

The nucleus is the command centre of a cell. This is because it contains the genetic material of the cell. Therefore, it consists of a number of structural elements which facilitate its functions. The nucleus of a cell has a spherical shape. A nucleus diagram is very useful for studying its structure. Its structure consists of the following.

Mitochondria play a critical role in the generation of metabolic energy in eukaryotic cells. As reviewed in Chapter 2, they are responsible for most of the useful energy derived from the breakdown of carbohydrates and fatty acids, which is converted to ATP by the process of oxidative phosphorylation.
