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

fractionation and electron microscopy. Each main component has its own‚ individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane‚ nucleus‚ cytoplasm‚ mitochondria‚ lysosomes‚ Golgi bodies‚ centrioles‚ endoplasmic reticulum (both smooth and rough) and ribosomes. The cell membrane - The cell membrane is also known as the plasma membrane and is located on the surface of all typical animal cells‚ it is covered by a double

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

Bio 93 Review Sheet: 1. Understand all the THEMES presented in the introductory lecture (lec 1). 2. What is an open system? Energy in and out‚ comes in and leaves as heat 3. What are the 4 most important elements in the human body? C‚ O‚ N‚ H 4. Draw the periodic square for Helium. How many valence electrons does it have? How do you figure this out using the periodic table? Two valence e-‚ 23He‚ all the way right full shell only holds two electrons 5. What is an isotope? How are they used

of its moisture. Tetrahymena Can you see the ink moving into the cells? Is it enclosed within the vacuoles? What are the distributions of the ink and carmine food vacuoles in each cell? How many food vacuoles of each type are in each cell? I did not actually see the ink “moving” into the cells‚ however it was extremely noticeable that once it did “move” the location of it was inside the vacuoles of

Cell wall- it is found outside the cell membrane‚ it is made up of cellulose. It protects and gives shape to the cell. It is freely permeable to water‚ gases and dissolved substances. (ii) A large central vacuole- it is a space filled with cell sap. The vacuole is often called sap vacuole and is surrounded by a membrane. It helps to maintain the shape of the cell. (iii) Chloroplasts- these are small structures lying in the cytoplasm. They contain the green

Animal and plant cells both transport protein into and out of cells through endoplasmic reticulum and have vacuoles where food‚ water‚ and nutrients are stored as well as provide stability for a plant. Three Differences Along with the similarities‚ there are also differences between animal cells and plant cells. Plant cells contain chloroplast to help make

How does the Paramecium regulate its water content? The Paramecium regulates its water content through their contractile vacuoles which excrete excess water. The excess water is collected into a contractile vacuole which swells and finally expels water through an opening in the cell membrane. Q 7. How does the Paramecium ingest food particles? Describe the process from detection to ingestion. The Paramecium ingests
