Document Summary
All living things are composed of one or more cells. The cell is the smallest entity that retains properties of life. Function is to regulate movement of substances via selectively semi-permeable (picking: while always allow water and oxygen in. Double layer made up of fat molecules (lipids); protein and carbohydrates. Material that all organelles in cells are suspended by: there is no cytoplasm in the nucleus. Store nutrients and waste until ready for disposal. Nuclear membrane has pores that allows passage of rna and other materials. Two types of cells: eukaryotic (plant or animal, prokaryotic (no nucleus) (bacteria) (oldest) --> no membrance bound organelles much smaller than a eukaryotic cell. Power house : converts energy for cellular respiration. Energy released and stored as form of atp (adenosine triphosphate) Energy is not made; here sugar is broken down releasing energy. Has 2 separate membranes: smooth outer membrane, folded inner membrane (finger-like projections in inner membrane called cristea, speeds up cellular respiration)
