Presentation transcript:

Lab Practical Know the following slides Be able to identify the type of cell Plant cell or animal cell

Onion Cells Iodine stain to see cells No chloroplasts Grow underground Visible nucleus Nucleolus inside nucleus

Elodea Cells No stain Live plants Green circles are chloroplasts

Cheek Cells Methylene Blue stain Blue circle inside is nucleus Irregular shape because lack of cell wall

Adipose Cells Large irregular shape Store fat

Skeletal Muscle Cells Dark lines inside of cells Extra mitochondria for energy Extra ribosomes for protein Tons of microfilaments and microtubules

Red Blood Cells Circular No nucleus and no mitochondria Heart pumps Extra room to store oxygen

Sickle Red Blood Cells Irregular Shaped Can’t store as much oxygen Cause blood clots

Which of the following scientists is not credited with the cell theory? 10 Rudolf Virchow Matthias Schleiden Robert Hooke Theodore Schwann 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Short Answer Part of Test Capacity to show two points that are close together as separate Sketch a letter under the compound light microscope Three parts of the cell theory T-chart comparing TEM and SEM Draw a picture of the cell membrane and label Diagram of osmotic solution
