cell ultrastructure

• centrioles


  Structures found in the cytoplasm made of microtubules that produce the spindle fibres during mitosis
• chloroplasts


  Organelles found in plants and algae that are the site of photosynthesis
• cilia


  Small hair-like structures that project from the surface of cells.
• confocal microscopy


  A type of microscopy that uses lasers to scan a specimen point by point to produce an image
• cytoskeleton


  A mesh of protein fibres found in the cytoplasm of eukaryotic cells used for structural support and intracellular transport
• differential staining


  Using multiple different stains to distinguish different parts of a specimen.
• eukaryotic cell


  A type of cell that contains a nucleus along with membrane bound organelles
• flagella


  A whip-like structure found on bacterial cells that is used for cell movement.
• golgi apparatus


  An organelle found in eukaryotic cells that is involved in the modification and packaging of proteins
• light microscope


  A type of microscope that uses a series of lenses to magnify the visible light reflecting off a specimen
• lysosomes


  Membrane-bound vesicles found in the cytoplasm that contain a hydrolytic enzyme called lysozyme
• magnification


  How much bigger an image appears compared to the original object, using I AM triangle
• mitochondrion


  An organelle found in eukaryotic cells that is the site of aerobic respiration
• nuclear envelope


  A double membrane that surrounds the nucleus, has pores
• nucleolus


  A structure found inside the nucleus that contains proteins and RNA and is involved in synthesizing new ribosomes
• nucleus


  An organelle found in eukaryotic cells that stores the genetic information of the cell as chromosomes and is surrounded by a membrane called the nuclear envelope
• plasma membrane


  A semipermeable lipid bilayer studded with proteins that surrounds the cell and many organelles
• prokaryotic cell


  A type of cell that does not contain any membrane bound organelles or a nucleus.
• resolution


  The ability to distinguish two different points in a specimen.
• ribosomes


  Organelles found either free in the cytoplasm or membrane bound that are involved in the synthesis of proteins.
• rough endoplasmic reticulum


  A membrane bound organelle that is involved in the synthesis and packaging of proteins.
• scanning electron microscope


  A type of microscope that passes a beam of electrons over the surface of a specimen to produce an image
• smooth endoplasmic reticulum


  A membrane bound organelle involved in lipid synthesis.
• transmission electron microscope


  A type of microscope that passes a beam of electrons through a sample to produce an image.
