Unit 7 P1 P1 TASK ONE Anatomy and physiology of a cell Name of parts of a cell | Anatomy(structures) | Physiology (function) | Nucleus | The nuclear envelope is a double membrane. Is has 4 phospholipid layers. It is also has large pores through which materials pass back and forth. | The nucleus regulates all cell activity. It does this by controlling the enzymes present. The chromatin is composed of DNA. DNA contains the information for the production of proteins. | Mitochondria | Mitochondria have two membranes (not one as in other organelles). The outer membrane covers the organelle and contains it. The inner membrane folds over many times (cristae). | The mitochondria provides energy for the cell. | Plasma membrane | Plasma…show more content…
Rough ER transports these proteins to the regions in the cell where it is needed. | Ribosomes | A ribosome is composed of two parts known as the large and small subunits. Each of these is a combination of protein and a type of RNA known as rRNA. | the main thing they do is that they arrange the strands of the amino acids for use of the other parts of the cell and ultimately the body. | Goigi Apparatus | The main function of the Golgi apparatus is to be responsible for handling the macromolecules that are required for proper cell functioning | It packages and ships molecules made in the ER. | Lysosome | Lysosomes are spherical bag like structures that are bound by a single layer membrane, however, the lysosome shape and size may vary to some extent in different organisms. The lysosome size ranges between 0.1 to 1.2μm. | Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. | P1 tasks 2 Organs | Anatomy | Physiology…show more content…
| Pancreas is able to produce the right chemicals at the right times in the right quantities in order to properly digest the food we eat. | Kidneys | Paired organs in the abdomen. | They prodouce urine. | Bladder | Near the pelvis | It stores urine | Uterus | In abdomen | They pass urine from the bladder to urethra | Ovaries | In the pelvis | They produced eggs (ovaries and hormones. | Liver | The liver is the second largest organ in the human body (after the skin) and the largest gland | It is located on the right side of the abdomen (to the right of the stomach) behind the lower ribs and below the lungs. | Intestines | Stomach alimentary canal,anus, | It digests foods | uterus | Below the pelvis | It passes urine. | P2 .Reproduction systems. Male * Penis-For removing waste fluids from the male body (urine). For insertion of sperm (in semen) with the female to produce offspring, so continues the cycle of human life. * Prostate- The function of the prostate gland is to secrete proteins and hormones that are added to the ejaculatory fluid produced by the seminal
