Materials:
mongo seeds, corn seeds, plastic cups
Procedure:
1. Soak mongo seeds and corn seeds overnight in water.
Carefully remove the seed coat and try to separate them in
halves. Classify them into monocot or dicot.
2. draw and label the parts of a monocot seed and dicot
seed.

5. How are dicots plants distinguish from other plants?

SUMMARY
A seed contains the plant embryo, the cotyledons,
and a seed coat. The seed coat is the end covering.
The cotyledons are also called seed leaves. They
contain endosperm which is the stored food in the
form of starch, sugar and oil. The endosperm
provides energy for the embryo. Seeds are classified
into dicots and monocots.
Given the proper conditions of air , moisture, and
temperature, a seed will develop into a new plant.
The process the seed undertakes from the time it
starts to sprout until it grows into a seedling is called
germination.
