1 Cell Theory Levels of Organization Cell Parts - Homeostasis
2 Homeostasis - maintenance of internal stable conditions in a constantly changing environment that are necessary for life's functions
3 Maintaining Homeostasis Get energy from food Plant Cells Photosynthesis to make sugar then the Mitochondria to convert the sugar to energy Animal Cells Get sugar from the food we eat then the Mitochondria to convert the sugar to energy Exchange material into and out of the cell via cell membrane Bring in nutrients and oxygen Get rid of wastes removed carbon dioxide from cell after cellular respiration Removed unwanted or unneeded chemicals Cell Division Growth and Repair Cell division to create more cells for multicellular organisms Reproduction Unicellular organisms to make offspring via Mitosis Multicellular organisms make sex cells via Meiosis

20 Station 1 1. What are the levels of organization in order from smallest to largest? Atoms, elements, molecules, compounds, cells, tissue, organ, organ system, organism 2. What is the pattern in the levels of organization? The patterns in the levels of organization is the smaller levels make up the larger levels. Ex: atoms make up elements Atoms and elements make up molecules

Compounds are made up of different elements While molecules are made up of the same elements. 2. Compound = different elements= CO 2 3. Molecule= same elements = O 2
22 Station 3 1. What are the three postulates of the Cell Theory. 1. The three parts of the cell theory are 1. Cells make up all living things 2. Cells come from other cells 3. Cells are the basic (smallest) unit of life 2. Can the information in the Cell Theory explain metal? Explain. 1. Information in the cell theory can not explain metal because metal is not alive.
23 Station 4 1. Define homeostasis. 1. Homeostasis is the process of keeping stable / balanced internal conditions. 2. A biotic factor is a worm or llama. An abiotic factor is the sun or rocks. Define biotic factor. Define abiotic factor. 1. A biotic factor is living things 2. An abiotic factor is non-living things
24 Station 5 1. How do the cells in a person s body help them in homeostasis? 1. A person s cells help maintain homeostasis by 1. removing waste 2. reproducing and making more cells 3. breaking down glucose to make energy 2. What organelles are involved in removing waste from the cell? 1. Organelles involved in removing waste are vacuole (store waste) and cell membrane (allows to exit) 3. Why do cells need to remove waste? 1. Cells have to remove waste because it can clogged up the cell and act as a poison.
25 Station 6 Location - Organelle Process Purpose Chloroplast Photosynthesis Use sun, water, and CO2 to make food ( sugar, glucose) for the cell Mitochondria Cellular Respiration Convert glucose to energy
26 Station 7 1. What is the function of the Stoma? 1. Stomas bring in CO2 and release Oxygen and water. 2. How is transpiration in plants similar to respiration in animals? 1. Both transpiration and respiration is the release of gases and water.
27 Station 8 1. Why is photosynthesis only found in plants? 1. Plants have to make their food (sugar / glucose) to get energy and photosynthesis is the process that makes the food. 2. How are the following terms related? Mitochondria, carbon dioxide, photosynthesis Photosynthesis makes glucose, and oxygen which is used in the mitochondria to make energy for the cell and release CO2
28 Station 9 1. What process creates energy for the cell? 1. Cellular respiration 2. How could the cytoplasm and vacuoles be similar? 1. Both are used in exocytosis 2. The cytoplasm stores and holds things together in the cell, vacuoles stores things inside it self
29 Station What is the function of the ribosomes? 1. Make proteins 2. What is the function of the nucleus? 1. Controls the cell 3. What is the function of cell membrane? 1. Lets things in and out
