What are the advantage of staining the cheek cells?
specimen is clearer and more observable
Relate the shape of frog's red blood cells and frog's egg cell with their respective
function.
RBC is oval its helps transport oxygen to through the frog’s body. WBC is amorphous it helps stores nutrients for growth and developement
Enumerate the shapes of cells studied and indicate the organ where they are found.
Fusiform or spindle shaped - frog stomach ( smooth muscle)
Spherical - frog ovary
Amorphous - wbc
oval - rbc
Whiplike flagella - frog testis

3 dimensional
Inversiom of image of a compound microscope?
Inverted
Inversion of dissecting microscope
Upright direction
Direction of movement of a compound microscope
Opposite direction
Direction of movemen of a dissectinf microscope
Same direction
How does one properly carry the microscope
Hold it with two hands, one at the arm, and one on the base
How does one improve contrast when using a dissecting microscope?
Shift the light source, make it dimmer or brighter, and properly adjust the iris diaphragm
Differentiate chromatin, chromatids, and chromosomes
chromatin are thin, thread like DNA material found in the nucleus when the cell is not dividing. Chromosomes are condensed and coiled chromatin visible during cell division, and chromatids are thick, identical copies of a chromosome joined at the centromere
why is white fish blastula used to demonstrate the different stages of the cell cycle?
the cells divide rapidly
