things are composed of cells? Cell theory What type of microscope would be best for studying the detailed structure of the surface of a plasma membrane? Scanning electron microscope The two basic types of cells are ______ and ______. Prokaryotic . . . eukaryotic When using a light microscope to view a cell you obtained from scraping under your fingernails‚ you notice that the cell lacks a nucleus; therefore‚ you conclude that the cell must be a type of ______ cell. Prokaryotic One

THE ORGANELLES OF EUKARYOTIC CELLS . The difference between Prokaryotic and Eukaryotic Cells is organelles‚ membrane enclosed structures that perform specific duties. The most important of all is the “nucleus‚” this holds the DNA and is surrounded by a double membrane. The Prokaryotic lacks a nucleus which is not partitioned from the other cells by membranes. The region between the nucleus and plasma membrane is called cytoplasm and in the Eukaryotic cell it consists of various organelles

Plants have two different ways to reproduce. The first one is vegetative reproduction. With this type all the plants that have the same parent have the same genetic make-up. This also lets plants pass adaptations on that they have abtained over the years. Plants with good genetic make-up usually spread quickly and take over an area. An example of this would be the dandelion. These plants can sprout from any part of the plant. An example of this is the potato‚ farmers will pick the potatoes and cut

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions

Cell Specialisation All cells are designed to perform a particular job within an organism‚ that is‚ to sustain life. Cells can become specialized to perform a particular function within an organism‚ usually as part of a larger tissue consisting of many of the same cells working together for example muscle cells. The cells combine together for a common purpose. All organisms will contain specialised cells. There are hundreds of types of specialised cells. Below is listed some of the major ones

They comprise both disaccharides and polysaccharides. ▪ Examples are Glucose‚ Galactose and Fructose. o • Isomers • Chemicals that share the same chemical formula but different structures (mirror images) • • Glucose “the blood sugar” • The primary source of energy in all living things • • Galactose • • Fructose “fruit sugar” Isomerization A chemical reaction in which a substance

Transport in Plants Matthew H. 9A 131002 Today I will be discussing our experiment and the basics of transport of minerals and water in plants. Transport in plants are called transpiration. Water evaporates from the leaves which cause a type of suction that draws water from the roots. The water travels up via the vascular bundles. This flow of water is called transpiration stream. Some pressure is created forcing some water out of the cells in into the spaces between the cells. The

Experiment title: Preparation of Biological Materials for Microscopic Examination Objectives: 1. To learn how to use a microscope. 2. To study the cell structure of starch grains‚ onion cells and cheek cells. 3. To differentiate the difference between starch grains‚ onion cells and cheek cells. Introduction: Microscope is an optical instrument use to magnify micro objects that hardly or impossible to be observed by naked eyes‚ so that the objects can be studied. Compound light microscope
