-
Describe the relationship between what is actually seen on the microscope slide and the orientation of the image viewed through the microscope.
It's the opposite.
-
Describe the consequences when moving from scanning, to low, and to high power.
Increased magnification, narrowing of depth of field
-
Describe the meaning of the term parfocal.
Increase in magnification power does not change of the position of the specimen.
-
nucleus
Houses the genetic code, which dictates protein synthesis, playing an essential role in other cell activities such as cell transport, metabolism, and growth.
-
cell (plasma) membrane
Serves as the boundary of the cell, maintains its integrity; protein molecules embedded in membrane perform various functions.
-
cytoplasm
Gelatinous substance made up of organized subunits called organelles.
-
nucleolus
Part of the nucleus; plays an essential role in the formation of ribosomes.
-
chromatin
Threadlike form of DNA, makes up the genetic material of the nucleus
-
microvilli
Border made up of epithelial cells in the small intestine; increases the surface area for the absorption of nutrients.
-
cilia
Hairlike projections of cells
-
flagellum
Single projection extending from the cell surface, similar to a cilium, only example in humans is the "tail" of the male sperm.
-
organelle
any of the many cell "organs" such as mitochondrion or ribosomes
-
ribosome
Organelle in the cytoplasm of cells that synthesizes protein; sometimes called a "protein factory"
-
rough endoplasmic reticulum
An organelle that forms a network of tubules and vesicles within a cell (contains ribosomes)
-
smooth endoplasmic reticulum
Region of endoplasmic reticulum system that does not contain ribosomes
-
Golgi apparatus
Organelle consisting of small sacks stacked on one another near the nucleus that makes carbohydrate compounds, combines them with protein molecules and packages them for distribution throughout the cell.
-
lysosome
Membranous organelle containing enzymes that can dissolve most cellular compounds, also known as the digestive bags of the cell.
-
peroxisome
Organelles that detoxify harmful substances that have entered the cell
-
mitochondria
Organelle in which ATP generation occurs; often called the "powerhouse" of the cell
-
centriole
One of a pair of tiny cylinders in the centrosome of a cell; believed to be involved with the spindle fibers formed during mitosis
-
microtubule
Component of the cell's cytoskeleton, provides cell structure; also involved in intracellular transport.
-
microfilament
Tough, flexible filaments that provide support and structure to the cell; also involved in cell mobility.
