Biology Cell Types Vocabulary and Exploration

Instructions: Look around your environment (home, yard, or community). Identify three things you think are alive and three things you think are not alive. For each, explain why you placed it in that category. Use at least two characteristics (example: grows, reproduces, uses energy, responds to environment, etc.). Alive 1. Tree 2. Dog Not Alive Why did you place it in that category? It grows moves, hears, sees and can reproduce 3. Cat 4. 5. 6. moves, hears, sees and can reproduce Water Bottle Rock Chair It does not grow, reproduce, or use energy It does not grow or reproduce It does not grow or reproduce Choose one example you aren’t sure about (for instance: a seed, mold, or something very small). Write a short explanation of why you’re uncertain. Seed – I’m not sure if a seed is alive because it doesn’t move or grow right away. But when you plant it and give it water, it starts to grow, so it might be alive. Keyword ATP bacteria Carbon dioxide cell Cellular respiration Compound light microscope eukaryote multicellular Information Molecule that stores and provides energy for cells Single-celled organisms; some are helpful, some harmful Memory Clue The cell uses ATP to do its work and stay alive. Some bacteria help us digest food. Plants take in carbon dioxide to make their food. Every living thing is made of at least The basic unit of all living things one cell. Process cells use to break down food and make Cellular respiration gives cells the energy energy they need. A tool that magnifies tiny objects like cells using I saw plant cells using a compound light light microscope. Humans are made of eukaryote cells Cells that have a nucleus and organelles with a nucleus. Organism made of more than one cell A dog is a multicellular organism. Gas used by plants during photosynthesis muscle neuron organelle photosynthesis prokaryote protist Red blood cell Root hair cell tissue unicellular White blood cell Your muscle contracts when you lift something. A neuron sends messages from your A nerve cell that sends signals through the body brain to your hand. The mitochondrion is an organelle that Small part of a cell that does a specific job makes energy. Process plants use to make food from sunlight, Plants use photosynthesis to make water, and carbon dioxide sugar. A prokaryote has no nucleus, just freeA simple cell without a nucleus floating DNA. A pond has protist creatures like Mostly single-celled organisms that live in water amoebas. A red blood cell moves oxygen to every Cell that carries oxygen throughout the body part of you. Plant cell that absorbs water and nutrients from The root hair cell helps the plant drink the soil water. A group of similar cells working together Muscle tissue helps you run and jump. An organism made of only one cell Bacteria are unicellular organisms. A white blood cell protects your body A blood cell that fights infections and diseases from germs. A type of tissue that helps the body move
