Introduction The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in

ONION EPIDERMIS INTRODUCTION An eukaryote is an organism whose cells contain a nucleus and other structures (organelles) enclosed within membranes. Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole a water-filled volume enclosed by a membrane known as the tonoplast which maintains the cell’s turgor (provide structural support) and controls movement of molecules between the cytosol
