(Hint: those buried deep in the cell probably do different things than those closer to the cell membrane). Structure does not affect function of the cells‚ cells have a particular structure that enables them to carry out their function in the best way. 2. Draw a labeled diagram of a small section of the plasma membrane and briefly describe its structure and function. 3. Describe the difference between the animal and plant cells. Plant Cells have cell walls‚ which makes them appear rectangular

Skin is the largest organ in the human body. It is made up of three layers‚ the epidermis‚ dermis and the hypodermis. The epidermis is the outer layer of skin that keeps out harmful germs and bacteria but keeps in the vital fluids that humans need to survive. The dermis is the inner layer of skin that contains blood vessels‚ nerves‚ hair follicles‚ oil‚ and sweat glands Until the late twentieth century‚ skin grafts were constructed from the patient’s own skin.

Cell wall is a fairly rigid‚ protective and supportive layer surrounding the cell external to plasma membrane of plants‚ bacteria‚ archaea‚ fungi and algae. It is absent in animals and most protists. It was first observed by Robert Hooke in 1665. It is not an entirely rigid structure as the cell wall expands due to the growth of the cell. It varies in thickness from o.1mm to I0mm.in most of the cells‚ cell wall is present from the very beginning to the last‚ but in slime molds (myxomycetes)

Skin cancer is the most common malignancy class that human can develop. The most common types are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Your skin grows really fast and has a ton of skin cells in every inch of your body. Your body is always doing its job of making new skin cells and also getting rid of old ones. You don’t see when the skin is falling off‚ but the skin you see now will be gone in about a month because it makes sure to get rid of the old skin and reproduce.

Cellulitis is a common skin infection caused by bacteria. Causes Staphylococcus and streptococcus bacteria are the most common causes of cellulitis. The skin normally has many types of bacteria living on it. When there is a break in the skin‚ however‚ bacteria can enter the body and cause infection and inflammation. The skin tissues in the infected area become red‚ hot‚ irritated‚ and painful. Risk factors for cellulitis include: • Cracks or peeling skin between the toes • History

How do skin receptors’ distribution change one’s reaction to pain in different areas of your body? Aim: Our senses are responsible for receiving information in the outside environment and sending it to our central nervous system‚ where this information is then interpreted. Organs such as the skin‚ known as sense organs‚ have specific neurons named receptors‚ which are each responsible for responding to specific types of stimulus. The receptors responsible for identifying our sense of touch are distributed
