Transcript Microscopes, Cells, and Cell Transport

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
