Question

short note on monocotyledonae​

Answer 1

$\huge\bold\purple{Answer:-}$

Monocotyledonae : These plants have single cotyledon in their embryo. They have adventitious root system and stem is rarely branched. Leaves generally have sheathing leaf base and parallel venation while the flowers are generally trimerous.

The vascular bundles are conjoint, collateral and closed type. In Monocots, except few plants secondary growth is absent. e.g. Zea mays (Maize), Sorghum vulgare (Jowar).

Answer 2

monocotyledons (/ˌmɒnəˌkɒtəlˈiːdən/),[d][13][14] commonly referred to as monocots, (Lilianae sensu Chase & Reveal) are flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided, the rest of the flowering plants having two cotyledons and therefore classified as dicotyledons, or dicots. However, molecular phylogenetic research has shown that while the monocots form a monophyletic group or clade (comprising all the descendants of a common ancestor), the dicotyledons do not.
