The cell theory states that all living things are made of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells.
Formed by joining many small molecules together.
Nucleic acids are macromolecules that form when long chains of molecules called nucleotides join together.
Proteins are long chains of amino acid molecules.
A lipid is a large macromolecule that does not dissolve in water.
One sugar molecule, two sugar molecules, or a long chain of sugar molecules make up carbohydrates.
The cell membrane is a flexible covering that protects the inside of a cell from the environment outside a cell.
A cell wall is a stiff structure outside the cell membrane.
A fluid inside a cell that contains salts and other molecules.
The cytoskeleton is a network of threadlike proteind that are joined together.
Every eukaryotic cell has other structures, called organelles, which have specialized functions. Most organelles are surrounded by membranes.
The nucleus is the part of a eukaryotic cell that directs cell activites and contains genetic information stored in DNA.
Chloroplasts are membrane-bound organelles that use light energy and make food, a sugar called glucose, from water and carbon dioxide in a process known as photosynthesis.
Passive transports is the movement of substances through a cell membrane without using the cell's energy.
Diffusion is the movement of substances from an area of higher concentration to an area of lower concentration.
Osmosis us the diffusion of water molecules only through a membrane.
When molecules pass through a cell membrane using special proteins called transport proteins.
Active transport is the movement of substances through a cell membrane only by using the cell's energy.
The process during which a cell takes in a substance by surrounding it with the cell membrane.
The process during which a cell's vesicles release their contents outside the cell.
Series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP.
The process by which glucose, a sugar, is broken down into smaller molecules.
The reaction that eukaryotic and prokaryotic cell can use to obtain energy from food when oxygen levels are low.
A series of chemical reactions that convert light energy, water, and CO2 into the food-energy molecule glucose and give off oxygen.
