what structures do you see in elodea that indicate that they are plant cells?

Back 26

Chloroplast, cytoplasm, cell wall

Front 27

Difference between animal and plant cells

Back 27

Plant- chloroplast, cytoplasm, cell wall

animal only have one membrane and cant produce their own food.

Front 28

what are the advantages of studying a live specimens

Back 28

studying patterns and behavior, reproduction, growth, hunting patterns, sleeping patterns, awareness of surrounding, motion, locomotion, protection, metamorphosis and economic relations.

Back 31

distinguish two points as being the same when you reach the point where you can't tell which is different.

Front 32

Back 32

deals with the light intensity

Front 33

Contrast

Back 33

biological stains help improve contrast

Front 34

Condenser lens

focus the light beam. Thin or thick.

Front 35

Objectives

Back 35

low- 4x

med- 10x

high-40x

Front 36

Parfocal

Back 36

focus remains when you change magnifications. always start at a low magnification

Front 37

Back 37

when you change objectives the object is still centered.

Back 60

random motion of molecules. Every molecule has motion. caused by heat. is a passive process ( means no work was involved)
