Echinodermeta is a phylum of marine invertebrates which includes starfishes, sea urchins, brittlestars, crinoids, and sea cucumbers. They have fivefold radial symmetry, a calcareous skeleton, and tube feet operated by fluid pressure.

Dicotyledonae (Dicots) consists of plants having seeds with two cotyledons and the plants are called dicotyledonous plants.
Example: Mango, neem, sunflower.
Monocotyledonae (Monocots) consists of plants having seeds with one cotyledon and the plants are called monocotyledonous plants.
Example: Grasses, sugarcane, maize and wheat.
