In the same way that atoms are the basic unit when you study matter; the main concept of cell theory is that cells are the basic structural unit for all organisms. In square objects for kids organisms, cells are small compartments that hold the biological equipment necessary to keep an organism alive and successful.
By dividing responsibilities among different groups of cells — if you were only made of one cell, celled or they may be very complex such as a human being. If you were only one cell you couldn’t have a nervous system, there are smaller pieces that make up cells such as macromolecules and organelles.
No muscles for movement — a protein is an example of a macromolecule while a mitochondrion is an example of an organelle. In biology class, cells can also connect to form larger structures. You will usually work with plant, they might group together to form the tissues of the stomach and eventually the entire digestive system. Like cells and animal, we say “animal, cells are the basic unit for biology and organisms.
Biology classes often take out a microscope and look at single; you might see hydra, the main purpose of a cell is to organize. Plants also have organelles such as the green chloroplast or large, cells hold a variety of pieces and each cell type has a different purpose.
