Revision:Eukaryotic Cells
From The Student RoomTSR Wiki > Study Help > Subjects and Revision > Revision Notes > Biology > Eukaryotic Cells Draw a diagram to show the ultrastructure of a generalised animal cell as seen in a electron micrograph
State one function of each of these organelles: ribosomes, rough endoplasmic reticulum (rER), lysosomes, Golgi apparatus, mitochondrion and nucleusRibosomes: Main site for protein synthesis. Rough endoplasmic reticulum: Is the part of the ER which is decorated/studded with ribosomes. The proteins that are made goes in to the ER and then are sent out in the cell. Lysosomes: Uses hydrolytic enzymes to produce macromolecules. Golgi apparatus: Modifies the products received from the rER and then are transported to parts of the membrane. Mitochondrion: the site for cellular respiration. Nucleus: Contains the inherited information and controls the function and genotype of the cell.
Compare prokaryotic and eukaryotic cells
Describe three differences between plant and animal cellsPlant cells has a cell wall, chloroplast and vacoule whereas an animal cell does not.
State the composition and function of the plant cellThe plant cell wall contain cellulose microfibrils which help the cell to maintain its shape.
