Flour, water, salt, and yeast are mixed, given time to react, and then baked. the product is a brown loaf of bread with many tiny holes from air bubbles. compare the properties of the products and the reactants.

The difference between reactants and product is in terms of Consistency, Porosity , Colour ,  Texture

Explanation:

There are following changes in the properties of the products and the reactants.

a) Consistency - The mixture of reactant was in the form of semi solid while the product i.e the baked cake is in the form of solid.

b) Porosity - The baked bread is comparatively more porous in structure as compared to the reactants.

c) Colour - Mixture of reactant are of light  color while product is dark brown in color

d) Texture - the texture of mixture of reactant is smooth while that of baked bread is partially rough.

d. organisms have cells with different shapes and functions.
