draw a cells appeared (morphology) in a microscopic field at a total magnification of 100 X
Homework Answers
- Field diameter is the unit measurements in millimetres or micrometers, indicating the field visualized by the eyepiece of the microscope.
- In case of total magnification= = eyepiece in magnification x objective magnification
- 100X objective is oil immersion lens. Total magnification will be (For 10 X eye piece) 100 x 10 =1000x
- Plants cells will be observed as fixed shapes due to cell wall.
- Animal cells will be irregular cells due to lack of cell wall.
- Nucleus is visible indicating eukaryotic cell.
- Chlorophyll pigmentation may be visualized if plant cells are observed without stains (like Elodea).
- Animal cells (like human cheek cells) may be observed using Methylene blue dye.
