Characteristics of Living Things chapter 3
The Cell Theory 1. All living things are made of cells 2. Cells are the basic unit of structure and function 3. All cells come from pre-existing cells
Life Processes 1. Nutrition - molecules used during respiration to create energy 2. Transportation - movement around a cell 3. Synthesis - smaller molecules are put together to create a larger molecule 4. Respiration - producing energy for cell processes 5. Excretion - removal of waste 6. Regulation - control of all cell processes 7. Reproduction - creation of new organisms
Types of Organisms Multicellular Unicellular (Single Celled)
Parts of a Cell Nucleus - controls the cell functions Cell Membrane - controls what goes into and out of the cell Chloroplast - center for photosynthesis in plants Cell Wall - Protects plant cells only Cytoplasm - liquid of the cell, allows movement of molecules Vacuole - stores water and nutrients
