Question:

PRACTICAL: (Microscopy) Plant / Animal Cell

Author: Muhammad Hassan 11B1



Answer:

1) Add a drop of water to clean slide 2) Peel off epidermal tissue from this layer / Remove cells from inside cheek with cotton bud 3) Use tweezers - place epidermal tissue into water on slide / Smear cotton bud onto slide 4) Add drop of iodine solution / Methylene blue (it's a stain & will make cell parts more obvious) 5) Place cover slip gently with forceps, avoid air bubbles (they'll obstruct view of your specimen)
