8 Limits to Cell Size - Blue Agar Simulation Lab p. 59
Cell size is limited by S.A./V. ratio,
since cells need large surface area to take in nutrients and excrete wastes.
Make agar "cells" with pH indicator brom cresol green
= basic; clear/yellow
- PROCEDURE FOR PREPARING CELL MODELS
agar "cells": 10, 30, 50, 70 mm.
- PROCEDURE FOR FEEDING CELL MODELS p. 60
agar "cells" in 0.3 N H2SO4 (Sulfuric Acid) for 7 minutes.
