Study Set Content:
distance between the objective lens and the coverslip
working distance
The circle you see as you look into the microscope
Field of view
How to change the light in the microscope
adjust the light from the rheostat knob or adjusting the iris diaphragm
to focus the light onto the specimen
Condenser lens
controls the amount of light reaching the specimen.
Iris Diaphragm
The thickness of the visible plane of the material that is in focus under a particular magnification
Depth of field
N/C
Area of nucleus/ Area of cell- Area of nucleus
The use of lens that bend the light differently or refract
Oil immersion lens
The nucleus is bounded by the
nuclear envelope
allow the movement of materials into or out of the nucleus
Nuclear pores
consists of 2 asters which are point of radiating fibers at each end(pole) of the cell and centrioles in the middle of the asters
Mitotic apparatus
energy in motion and the driving force of movement of atoms and molecules
Kinetic energy
collective collisions of many molecules striking a larger structure and causing it to move
Brownian motion
who discovered brownian motion
Robert Brown
difference between the two concentrations is known as
concentration gradient
If the particles become uniformly dispersed it is in
equilibrium
The liquid portion of the solution
solvent
dissolved portion
solute
More concentration of solutes
hypertonic
Less concentration of solutes
hypotonic
