what are centrioles? 
Structures found in the cytoplasm made of microtubules that produce the spindle fibres during mitosis
What are chloroplasts?
Organelles found in plants and algae that are the site of photosynthesis
What are cilia?
Small hair-like structures that project from the surface of cells
What is confocal microscopy?
A type of microscopy that uses lasers to scan a specimen point by point to produce an image
What is a cytoskeleton?
A mesh of protein fibres found in the cytoplasm of eukaryotic cells used for structural support and intracellular transport.
What is differential staining?
Using multiple different stains to distinguish different parts of a specimen
What is a eukarytoic cell?
A type of cell that contains a nucleus along with membrane bound organelles.
What are flagella?
A whip-like structure found on bacterial cells which is used for movement
What is golgi apparatus?
An organelle found in eukaryotic cells that is involved in the modification and packaging of proteins
What is a light microscope?
A type of microscope that uses a series of lenses to magnify the visible light reflecting off a specimen
What are lysosomes?
Membrane-bound vesicles found in the cytoplasm that contain a hydrolytic enzyme called lysozyme.
What is magnificiation?
how much bigger an image appears compared to the original object
How is image size calculated?
Image size = Actual Size x Magnification
What are the mitochondrion?
Organelles found in eukaryotic cells that are the site of aerobic respiration
What is a nuclear envelope?
A double membrane that surrounds the nucleus
What is a nucleolus?
A structure found inside the nucleus that contains proteins and RNA and is involved in synthesizing new ribosomes.
What is a 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.
What is a plasma membrane?
A semi-permeable lipid bilayer studded with proteins that surrounds the cell and many organelles.
What is resolution?
The ability to distinguish two points in a specimen.
What are ribosomes?
Organelles found either free in the cytoplasm or membrane bound that are involved in the synthesis of proteins.
What is a rough endoplasmic reticulum (RER) ?
A membrane-bound organelle that is involved in the synthesis and packaging of proteins
What is a scanning electron microscope (SEM) ?
A type of microscope that passes a beam of electrons over the surface of a specimen to produce an image.
What is a smooth endoplasmic reticulum (SER) ?
A membrane-bound organelle involved in lipid synthesis
What is a transmission electron microscope (TEM) ?
A type of microscope that passes a beam of electrons through a sample to produce an image
What is a prokaryotic cell?
A type of cell that does not contain any membrane bound organelles or a nucleus.
