a cell. It is usually associated with a specific chromosomal site and involved in ribosomal RNA synthesis and the formation of ribosomes. | Ribosomes | Ribosomes are cell organelles that consist of RNA and proteins. They are responsible for assembling the proteins of the cell. | Golgi apparatus | a cell structure mainly devoted to processing the proteins synthesized in the endoplasmic reticulum (ER). | Mitochondrion | which is to generate large quantities of energy in the form of

the environment, cytoplasm that surrounds the chemicals and structures of a cell (example paramecium), as well as the small size of cells so the surface area and volume are proportional to each other to help maximize the efficiency of the cells. 6. In eukaryotic cell there is a nucleus present versus only the presence of genetic material in prokaryotic cells (example in cheek cell). Eukaryotic cells also have membrane bound organelles which allow compartmentalization within cells allowing eukaryotic

Structures Nucleus- The nucleaus is a membrane bound strcture. It is the command centre of most cells and is usually most prominent feature within a cell. Cytoplasm - Cytoplasm is the substance that fills the cell. It is a jelly-like substance and it is made up of eighty percent water and is usually clear and colourless. Cytoplasm is a thick gel-like substance. Mitochondria - They are made of two membranes. The outer membrane covers the organelle and

and Plant Cell Structures Instructions: Your lab report will consist of the completed tables. Label each structure of the plant and animal cell with its description and function in the tables provided. When your lab report is complete, post it in Submitted Assignment files. 1. Animal Cell: Observe the diagram showing the components of an animal cell. Using the textbook and virtual library resources, fill in the following table: Animal Cell Number | Cell Structure | Description

cell membrane aids in the protection of the cell, as it helps to control the movement of particles that pass in and out of the cell. The structure of the phospholipid is made up of hydrophilic heads and hydrophobic tails. Cytoplasm – The cytoplasm is a gel-like substance that is clear in colour made up of 80% water and also contains enzymes, salts, organelles and other organic molecules. It consists of all the contents outside of the nucleus and is encased within the cell membrane. The cytoplasm

the carbon dioxide needs to be removed from the cells. The active transport pumps shut down the plasma membranes of Josephs heart. C. All intracellular organelles have membranes as part of their strtucture, such as the endoplasmic reticulum, Golgi apparatus, mitochondria, and the nucleus. The breakdown of the membranes of these structures affect the function of Josephs heart cells. If the mitochondria membrane becomes damaged it cannot produce ATP. Some of the channels in the plasma membrane

Complex organisms-multicellular The cell was discovered by Reginald Hooke in between 1635-1703 • He used a slice cork under the microscope to discover and saw empty spaces, which he called cells Cells are the basic unit of life. • For any structure to be called a cell it will have to have 3 or 4 basic features o (animal) round, plasma membrane (outside), nucleus (middle of the cell), cytoplasm (in btwn the nucleus and the plasma membrane) have 3 components. Be able to draw this. o (plant)
