Cells

  • Living - Things made of cells that carry on life functions.

     

    Organism – It is a living thing.

     

    Dead - Things made of cells that no longer carry on life functions.

     

    Nonliving - Things not made of cells, just atoms.

     

    Cells - They are the basic units of living things.  They provide structure (shape) and help the organism carry on life functions to sustain life.

     

    Cell Wall - Gives the cell shape & protects what’s inside.

     

    Cell Membrane - Controls what goes in or out of a cell.

     

    Cytoplasm - The liquid that fills the cell.

     

    Nucleus - Stores chromosomes and controls the cell.

     

    Chromosome - Stores genetic information.

     

    Mitochondria - Does cell respiration to change food into energy.

     

    Ribosome - Makes cell parts (proteins).

     

    Vacuole - Stores food water or waste products.

     

    Lysosome - Makes digestive fluids to digest foods.

     

    Multi-cellular - these are living things with more than one cell.  Animals, plants & fungi are always examples.

     

    Tissue - Groups of cells that help perform the same function. Bone or muscle tissue are examples.

     

    Organ - Several tissues working together to perform a function.  Femur and heart are examples.

     

    Organ System - Several organs working to perform a function.  Skeletal and circulatory systems are examples.

     

    Life Functions – Processes that all living things do.

     

    Growth – The life processes that cause an organism to increase in size.

     

    Development – The process of orderly change in living things that is sometimes called a life cycle.

     

    Metamorphosis - Life stages of an animal such as an insect or frog.

     

    Reproduction – Asexual or sexual processes that create new cells or organisms.

     

    Dynamic Equilibrium or Homeostasis - The condition & processes to maintain an internal chemical balance.

     

    Releasing Energy for Use – The process where organisms take in food (or the nutrients to make their own in photosynthesis) and then do cell respiration to meet their energy needs.

     

     Respond to Change – Organisms go through physical or behavioral changes as the environment changes (stimuli).

     

    Evolution – The processes that cause species to change over many generations as the environment changes.

     

    Field of View – The circle of light as seen through a microscope or telescope.
