A part of the experiment that no changes are made to.You use the control group as a comparasion.
The branch of biology that deals with microorganisms and their effects on living organisms.

All made up of cells
Chemicals of life (organic compund)
Responding to surroundings
Growth and development
Characteristics of living things (what makes something classified as living)
List all 6
Needs of living things (what do living things need to survive) List all 4
All living things are made up of cells
Cells are the smallest unit of life
All cells come from pre-existing cells
List 3 statements of the Cell Theory
1. In a plant cell only
2. A stiff wall surrounds the cell membrane, giving the cell a rigid boxlike shape
1. Protects the cell and regulates what substances enter and leave the cell
2. In animal cells, form a barrier between the cytoplasm and the environment outside the cell
Chloroplast>In a plant cell only
1. A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food
1. Rod-shaped cell structures that produce most of the energy needed to carry out the cell's function
Endoplasmic Reticulum (ER)
1. A Cell structure that forms a maze of passageays in which protiens and other materials are carried from one part of the cell to another
1. A water-filled sac inside a cell that acts as a storage area
2. Larger in plant cells because they need to store larger amounts of water for times when only a limited supply is available to them
1. A structure in a cell that receives protiens and other newly formed materials from the endoplasmic recticulum, packages them, and distributes them to other parts of the cell
1. A cell structure that contains nucleic acids, the chemicals instructions that direct all the cell's activities
1. material in the cells that contains DNA and carries gentic information
1. A double rod of condensed chromatin; contains DNA that carries genetic information
1. The movement of materials through a cell membrane using energy
2. Needs ATP
3. Movement from low to high concentration
1.The movement of materials through a cell membrane without using energy
2. Does not need ATP
3. Movement from high to low concentration
1. Cells break down simple food molecules such as glucose and release the energy they contain
2. The body's energy molecule is called ATP
The process by which plants and some other organisms capture the energy in sunlight and use it to make food
Three structural difference between DNA and RNA
DNA: ? RNA: ?
DNA: ? RNA: ?
DNA: ? RNA: ?
Darwin's Theory of Natural Selection
4. Survival of the fittest
