The genetic material in the cell. Composed of C, H, O, N, P, and some S. It is shaped like a ladder with crosspieces on the ends and rods connecting them.
This is what carries the information from the chromosome to the ribosomes where proteins are made. It is a single strand.
Mitosis is the processes of taking old cells and making them into two new daughter cells that are exactly like the original. The purposes of mitosis are to remake old cells, the organism can add new cells to get bigger and if a cell is injured or damaged.
These are protiens that speed up or slow down the chemical processes in cells. It controlls the speed and activity the cell is doing.
Also known as amino acids. They are a part of the cell membrain and make up many of the organells in the cell membrain.
Complex molecules composed of Carbon, Hydrogen, Oxygen, Nitrogen, and Phospourus. Carry all the information necessary for an organism to carry out reproduction.
The organelles in an animal cell to which the spindle fibers attach just before mitosis occurs. Plant cells do not have centrioles, because the spindle fibers attach directly to the cell wall.
The middle structure of a double chromosome that attaches the two halves of the chromosome together.
Cells that have a membrane around the nucleus and other membrane-bound organelles. All organisms, other than bacteria, are eukaryotic
food chain (web)
The circle of life where one type of organism depends upon another for nutrients or raw
One-celled organisms, like bacteria, simply split in half and make two cells out of one. Each daughter cell is exactly like the parent cell, genetically.
An organism that cannot produces it's own food. It uses the energy from the autotrophs it eats to reun cell processes.
A process that only autotrophs and plants do. 6 Carbon molecules, 6 Hydrogen molecules and water (H2O) enter the organim and prodouces 1 glucose molecule (C6H12O6) and 6 Oxygen molecues.
A process that all organisms do. It's the exact oppostire if Photosynthesis. 1 glucose molecule (C6H12O6) and 6 Oxygen molecues enter the organism and produces 6 Carbon molecules, 6 Hydrogen molecules and water (H2O).
One of the by-products of fermentation in the human body. When the human body is
exercising and cannot breathe in oxygen fast enough, the body carries out fermentation to produce energy. This releases less energy and produces lactic acid which causes muscles to become sore.
ethyl alcohol (ethanol)
another by-product of fermentation in yeast and some other simple organisms. When they carry out fermentation, the alcohol and carbon dioxide are produced. Beer and wine makers, and bakers use yeast to make their product,
Selectively permiable means that smaller particles can go throug, but bigger particles cannot. An example of this would be all cell membrains.
The cell membrain is a barrier composed of protiens and lipids. It is selectvely permiable and only lets in particles that can hlep the cell.
the organelle that breaks down glucose to release the energy needed for the
cell to survive
The organelle within the nucleus that specifically governs the cells ability and timing for reproduction.
The process of diffusion of water. It moves from a higher concentration to a lower concentration.
