Microscopy‚ Cell Structure and Function Task 2 I: Name and describe the four main types of tissues in animals stating their functions and their location in the body give two examples of each type. The four main types of tissues that you will find in eukaryotes are connective‚ muscle‚ nervous and epithelial tissues; each of which having very different roles. Connective Tissue The first tissue type I am going to look at is the connective tissue. This tissue is found all over the body‚ including
Premium Organelle Cell Eukaryote
Eukaryotic cell‚ most of the DNA is found in the Nucleus. The Nucleus contains three distinct parts‚ the Nuclear envelope‚ the Nucleolus‚ and Chromatin. The Nuclear envelope is a double membrane. Also pore complexes connect the nucleus to the Endoplasmic Reticulum. The Nucleolus doesn’t have a membrane structure. It serves in the production of ribosomes. Lastly‚ Chromatin is material consisting of DNA and proteins. In a Prokaryotic cell‚ the DNA is concentrated in the Nucleoid. The Nucleoid is also not

cytoplasm comprises cytosol‚ the gel-like substance enclosed within the cell membrane – and the organelles – the cell’s internal sub-structures. The air in the factory behaves the same way. It brings vital things like oxygen to the workers. The endoplasmic reticulum (ER) is an organelle of cells that forms an interconnected network around the cell. Its job is to move proteins around the cell. A conveyor belt acts the same way‚ carrying around the necessary materials . The Ribosomes are the protein builders

process regulated by p53 is an intracellular system that involves the break down of cytoplasmic contents within the lysosome. This mechanism is a form of adaptation to cellular stress such as starvation‚ trophic factor deprivation‚ hypoxia‚ endoplasmic reticulum (ER) stress and oxidative stress (Levine & Abrams‚ 2008). Through adaptation‚ it allows the prevention of cell death. There are three types of autophagy: macroautophagy‚ microautophagy‚ and chaperone-mediated autophagy (CMA). They all are involved

pipes produce water that is very important to the house. 4. Golgi apparatus is like a MAIL BOX ... Just like the mail box it processes and packages proteins for delivery to other organelles in the cell after they have been synthesized. 5. Endoplasmic Reticulum is like the KITCHEN ... where we made food and deliver it to family just like the ER where proteins and lipids are being mad. 6. Centriole is like a CLOTHING RACK ... because Centriole organizes cell division and just like the clothing rack

Cytoplasm includes the organelles and the inclusions. Organelles are highly specialized structures and often enclosed in their own membrane within the cytoplasm‚ specialised for specific activities. They include nucleus‚ mitochondria‚ endoplasmic reticulum‚ ribosomes‚ Golgi apparatus‚ lysosomes and cytoskeleton. The organelle with the largest volume is the nucleus‚ which contains the genetic material. (See Figure 1). Cell Inclusions are secretory and storage chemical substances without membranes

albumin and taken up by the hepatic cells. Two nonalbumin proteins‚ isolated from the liver cell cytoplasm and designated Y and Z‚ account for the intracellular binding and transport of bilirubin. The conjugation of bilirubin occurs in the endoplasmic reticulum of the hepatocyte. An enzyme‚ uridyldiphosphate glucuronyl transferase(UDPGT)‚ transfers a glucuronic acid molecule to each of the two proprionic acid side chains in bilirubin‚ converting bilirubin into a diglucuronide ester.
