• The characteristics of life are the ability to move, respire, grow, excrete, reproduce, metabolize, and be responsive to the environment
• Characteristics of life


  • Move
  • Respire
  • Grow

  • Reproduce
  • Metabolize
  • Be responsive to the environment
• Breathe


  To take in and use oxygen
• Grow


  To increase in size
• Reproduce


  To produce again
• Metabolize


  The chemical reactions in the body cells that change food into energy
• Move


  To change place or position
• Responsive to environment


  Tailored to meet each thing's developmental levels, needs, cultures
• Microscopes


  • 3 Objective lens
  • Scanning magnifications
• Animal cells


  • Low power 10x
  • High power 40x
• Nucleus


  Contains the chromosomes
• Nuclear Envelope


  A double membrane that protects the nucleus of a eukaryotic cell from the cytoplasm
• Nucleolus


  Makes part to help build one of the most important workers for the cell, the ribosomes
• Cytoplasm


  The jelly-like liquid that fills the inside of a cell
• Golgi Apparatus


  An organelle that acts as the packaging center of the cell
• Mitochondrion


  Organelles, or cell parts, often referred to as the powerhouse of cells
• Cell membrane


  A thin, tough wall surrounding the cell
• Endoplasmic reticulum (ER)


  A collection of tubes that make, package, and transport proteins and fats
• Lysosome


  Important organelles that help break down, or digest, certain materials inside the cell
• Ribosome


  A small organelle involved in the process of making Protein
• Plant cell


  • Cell wall
  • Peroxisome
  • Chloroplast
  • Amyloplast
  • Vacuole
  • Cytoskeleton
• Cell wall


  A strong, protective structure that surrounds a plant cell
• Peroxisome


  Small vesicles found around the cell
• Chloroplast


  Small, but critical structures inside of plant cells
• Amyloplast


  A colourless plastic that forms and stores starch
• Vacuole


  A storage area for the cell
• Cytoskeleton


  Maintains or changes the shape of the cell
• Epidermal cells


  • Part of the outer layer of an organism
  • Control the opening and closing of pores (called stomata), thereby regulating gas exchange and water loss in the plant
• Guard cells


  • The closing pores cells that control the opening and closing of stomata
• Palisade mesophyll cells


  • Live right underneath the upper surface of the leaves
  • Have abundant chloroplasts to help absorb sunlight for photosynthesis
• Blood cells


  • Carry fresh oxygen all over the body
• White blood cells


  • Protect you against illness and disease
• Muscle cells


  • The contractile cells in the mature muscle of an animal
• Nerve cells (neurons)


  • Carry electrical messages around the body
• Skin cells


  • Your skin is made up of trillions of cells that continually reproduce, replacing damaged, worn-out cells with new ones
