Cells are the basic units of structure and function in living things
A microscope is an instrument that makes small objects look larger.
The cell theory states the following:
*All living things are composed of cells.
*Cells are the basic units of structure and function in living things.
*All cells are produced from other cells.
A tiny cell structure that carries out a specific function within the cell
A plant's cell wall helps to protect and support the cell.
The cell membrane controls what substances come into and out of a cell.
the nucleus is like cell's control center, directing all of the cell's activities.
The region between the cell membrane and the nucleus; in organisms without a nucleus, the region located inside the cell membrane.
Mitochondria are known as the "powerhouses" of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions.
A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
A small grain-like structure in the cytoplasm of a cell where proteins are made.
A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.
A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.
A sac inside a cell that acts as a storage area.
A small, round cell structure containing chemicals that break down large food particles into smaller ones.
An element is any substance that cannot be broken down into simpler substances.
Two or more elements that are chemically combined.
Energy-rich organic compound, such as a sugar or a starch, that is made of the elements carbon, hydrogen, and oxygen.
Energy-rich organic compound, such as a fat, oil, or wax, that is made of carbon, hydrogen, and oxygen.
Large organic molecule made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
A small molecule that is linked chemically to other amino acids to form proteins.
A type of protein that speeds up a chemical reaction in a living thing.
Deoxyribonucleic acid; the genetic material that carries information about an organism and is passed from parent to offspring.
Ribonucleic acid; a nucleic acid that plays an important role in the production of proteins.
A property of cell membranes that allows some substances to pass through, while others cannot.
Diffusion is the main method by which small molecules move across the cell membrane.
The diffusion of water molecules through a selectively permeable membrane.
The movement of materials through a cell membrane without using energy.
The movement of materials through a cell membrane using cellular energy.
