CB1 Cell Structure

• Total magnification is the power of the eyepiece multiplied by the power of the objective lens
• A stain is a chemical used to show the cell components more clearly under a microscope
• A coverslip is used to keep the specimen flat when preparing a slide
• A micrometer is 1/1000th of a millimeter
• Plant cells typically contain: nucleus, membrane, cytoplasm, cellulose cell wall, vacuole, mitochondria, chloroplasts, ribosomes
• Animal cells typically contain: nucleus, membrane, cytoplasm, mitochondria, ribosomes
• Fungal cells typically contain: nucleus, membrane, cytoplasm, cell wall, vacuole, mitochondria, ribosomes
• Bacterial cells typically contain: membrane, cytoplasm, cell wall, one circular chromosome, several plasmids, ribosomes
• The cell wall supports the cell
• Mitochondria are the site of some chemical reactions for aerobic respiration
• Chloroplasts are the site of photosynthesis
• The cell membrane controls what moves into / out of the cell
• Cytoplasm is the site of many of the cell’s chemical reactions
• A vacuole contains a sugary solution called sap
• Ribosomes are the site of protein synthesis
• Plasmids are circular pieces of DNA
• How many micrometers are in a millimeter?

  1000 micrometers in 1 millimetre
• What does a plant cell typically contain

  Nucleus, cell membrane, cell wall, vacuole, cytoplasm, ribosomes, mitochondria, chloroplast
• What does a animal cell typically contain?

  Nucleus, cell membrane, cytoplasm, ribosomes, mitochondria
• What does a fungal cell typically contain

  Nucleus, cell membrane, cell wall, cytoplasm, ribosomes, mitochondria, vacuol
• What does a bacterial cell typically contain

  DNA molecule, plasmids, cell membrane, cytoplasm
• What is function of the cell wall


  It protects the cell and gives it structure
• What is the difference between a plant cell wall and bacterial and fungal cell walls

  Plant cell walls are made of cellulose while fungal and bacterial are made of something else.
• What is the function of the mitochondria

  It is the site of aerobic respiration and some chemicals reactions
• What is the function of the chloroplast

  It is the site of photosynthesis
• What is the function of the cell membrane

  The cell membrane controls what moves into the cell and what comes out
• What is the function of the cytoplasm

  It is the site of most chemicals reaction within the cell.
• What is the function of the vacuole

  The vacuole contains the sugary cell sap.
• What is the function of the ribosomes

  It is the site of protein synthesis.
• What are plasmids


  Plasmids are small circular pierces of DNA
