Introduction
An angiosperm (flowering plant) can either be monocotyledonous (a monocot) or dicotyledonous (a dicot) according to the number of embryonic seed leaves (cotyledons) in the seed. In the case of a monocot, there is only one photosynthetic cotyledon present in the seed, and in the case of a dicot, there are two photosynthetic cotyledons present in the seed, hence the name. The cotyledons of a dicot may also emerge and show above the ground when the seed germinates.
This assignment will further identify the two types of angiosperm using characteristics of the internal and external structure, as well as through the use of samples of each type of flowering plant.
Monocotyledonous plant
The scientific name for a monocotyledon is liliopsida. A flowering plant characterized by having one photosynthetic embryonic seed leaf or cotyledons in the seed. Monocotyledonous plants can also be identified:-
• When flowers grow, as the petals are formed in multiples of three (trimerous).
• Each pollen grain of a monocotyledonous plant has one pore.
• In the stem of a monocot, the vascular bundles are scattered.
• The monocot roots are fibrous roots.
• In monocots, the leaves have parallel venation.
Dicotyledonous plant
The scientific name for a dicotyledon is Magnoliopsida. A flowering
