12 Cell MembraneA protective barrier that encloses a cell and acts as a barrier between the inside of a cell and the cells environment.
13 CytoplasmThe jelly-like fluid found inside of cells that the organelles “float” in.
14 OrganellesSmall bodies in a cell’s cytoplasm that are specialized to perform specific functions.
15 NucleusThe Organelle that contains the cells DNA (the genetic material) and is the control center of the cell.
16 RibosomeThe organelle in which amino acids are hooked together to make proteins.
17 Endoplasmic Reticulum The organelle that makes lipids, breaks down drugs and other substances, and packages proteins for Golgi complex.They also help to transport things throughout the cell. (serve as a delivery system)
18 MitochondriaThe organelle that breaks down food molecules to make ATP (energy) needed to power the various processes in the cell.
19 ChloroplastThe organelle that uses the energy of sunlight to make food in a process called photosynthesis.The food is called glucose.Found in plant cells.
20 Golgi ComplexThe organelle that processes and transports proteins and other materials out of the cell.
21 VesicleA small sac that surrounds material to be moved into or out of a cell.
22 VacuoleThe organelle that stores water and other materials.
23 LysosomeThe organelle that digests food particles, waste, cell parts, and foreign invaders.
24 Cell WallA rigid/stiff structure that surrounds the cell membrane of plants, algae and prokaryotic cells and provides support.
25 The Organization of (multi-cellular) Living Things Cells – The smallest unit that can perform all life processes. (The building blocks of life)Tissue – A group of similar cells that can perform a common function.Organ – a collection of tissues that carry out a specialized function of the body.Organ System – A group of organs that work together to perform body functionsOrganism – A complete living thing
30 Structure and Function Structure – The arrangement of parts of an organism (what it is made up of and how it is put together)Function – the special, normal, or proper activity of an organ or part (it’s job or purpose)
31 Unicellular –vs- Multi-cellular organisms Unicellular Organisms are made up of only one cellMulti-cellular Organisms are made of many cells
32 Benefits of being Multicellular Larger Size – Large organisms are prey for fewer predatorsLonger Life – Life span is not limited to the life span of a single cellSpecialization – Each type of cell has a particular job so the organism is more efficient.
