Procedure 3 Esamining Celllar Dverty wth Microson The structure of different cell types can vary drastically. Cells differ not only in size and shape but also in the types and prevalence of organelles in the cell In this activity you will examine prepared microscope dlides of red blood cells, sperm cells, and skeletal muscle cells. Use the techniques you learned in low power, and advance to high power for each slide. Note that sperm cells can be difficult to find, so an oil inmersion ens is helpful to find the tiny cells. Draw, colos and label the cellular structures and organelles that you se on each slide You may wish to look at Figures 5.9 ip. 116) for red blood cells, 5.10A (p. 122) for skeletal ouscle, and 27,.1s (p.724) or sperm cells Unit 3: Begin your observation on Cytology UNIT A 4 79

Explanation / Answer

sperm cells - these are specialised cells having a head neck and a tail

head-it contains the genetic information carried by the cell

neck - it contains mitochondria required for production of enery

tail - serves the purpose of propagation

size of cell- it is about 50micrometers

smooth muscle cell-these are fuaiform shaped cells serving the gunction of contraction and relaxation to digest food in stomach and intestines. lack striations.

size- nearly 10 micrometers
