Instructions: For the purpose of grading the project you are required to perform the …

1.Organisms that can manufacture their own chemical energy sources are called _____________. 2.________ depend on energy stored in chemical bonds by autotrophs for their food energy. 3.Simple molecules are further broken down in cells in a process called _________, during which energy stored in their chemical bonds is used to …

It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. The cell is the basic structural and functional unit of all known living organisms. Some organisms are unicellular (made of only one cell) while others are multicellular …

All living things are made up of units called cells. A cell, the basic unit of life, is a microscopic structure that forms the basic structural as well as functional unit of living organisms. Cells can be divided into two categories called prokaryotic and eukaryotic cells. Prokaryotic cells are simple …

1.Nucleus – The nucleus generally contains the genetic material for the cell. Because it contains the DNA and chromosomes, which affect the proteins that determine the activities of the cell, the nucleus can be considered to be the cell’s control centre. 2.Cytoplasm – The cytoplasm contains primarily water and protein …

White blood cell (WBC)—A white blood cell is one of the three main types of blood cells. They are produced in the bone marrow and released into the blood. White blood cells are responsible for fighting infection. There are several kinds of white blood cells, including monocytes, lymphocytes, neutrophils, eosinophils, …

Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane), however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability …

Purpose of Experiment: To determine the effect of concentration of reactants on the current produced by a galvanic cell. Hypothesis: The greater the concentration of solution in the two half cells reacting with the two metals to produce current, the greater the flow of current will be produced from the …

These pigments are betalain pigments (not, as often thought, anthocyanins), which they replace in some organisms. They are named after the Beet family of plants (Beta) but are also found in fungi (Fly Agaric – the red, spotted one!). In petals they presumably attract pollinating insects and may be present …
