Secondary growth is characteristic of dicotyledonous angiosperms and gymnosperms. Riccia, Funaria, and Selaginella do not exhibit secondary growth.

Mango is a dicotyledonous plant. Coconut, sugarcane, and banana are monocots.

Dicotyledons are characterized by the presence of a tap root system, whereas monocots typically have fibrous root systems.

Double fertilization is a unique process exclusive to angiosperms, involving the fusion of one male gamete with the egg and another with the polar nuclei.

Angiosperms have the greatest extent of adaptation to various environments, allowing them to dominate almost all terrestrial ecosystems.

Monocots typically have floral parts in multiples of 3 (trimerous), not 4 or 5. Multiples of 4 or 5 are characteristic of dicots.

A rose is a dicot, characterized by net venation and floral parts in multiples of 4 or 5. Palms, orchids, and bananas are all monocots.

Double fertilization is a unique characteristic of angiosperms, not gymnosperms. Gymnosperms produce seeds but do not undergo double fertilization.

Triploid endosperm is formed by the fusion of one male gamete with two polar nuclei, a process known as triple fusion, which is exclusive to angiosperms.

Monocots have closed vascular bundles (lacking cambium). Open vascular bundles, which allow for secondary growth, are characteristic of dicots.
