Monocots

• Monocots are a class of angiosperms (flowering plant)

• They’re diverse, ranging from tiny duckweeds to large palms and climbing vines.

Types of Organisms

Duckweed is a free-floating aquatic plant which grows in both still and running freshwater, such as lakes, rivers, and streams.

Plant whose stem requires support and that climbs by tendrils or twining or creeps along the ground, or the stem of such a plant.

Monocots

• Monocots are primarily tropical. Many exist in other environments as well along in streams and ponds, in coastal marine environments, in deserts and even in the arctic tundra.

Human Uses

• Monocots are perhaps the most important organisms on earth. Some important foods-corn, rice, wheat, and barley- all come from monocots.

• Sugar cane, pineapples, dates, bananas, and many of our familiar tropical foods also come from monocots.

Morphology (body shape)•Includes some of the largest and most familiar groups of plants, including lilies, orchids, agaves, palms, and grasses.

• Monocots compromise about 67,000 species, or ¼ of all flowering plants.

Life CycleAngiosperm life cycle. The dominant sporophyte produces spores that develop into male gametophytes (pollen grains) and female gametophytes (embryo sacs).

Fertilization of the gametes produces a zygote which can germinate into a seed enclosed within a fruit, and eventually grow to be a sporophyte.

Structure of SeedCotyledon: the primary or rudimentary leaf of the embryo of seed plants

Epicotyl: The stem of a seedling or embryo located between the cotyledons and the first true leaves

Radicle: The part of a plant embryo that develops into a root.

Seed Coat: The outer protective covering of a seed.

Endosperm:The nutritive tissue within seeds of flowering plants, surrounding and absorbed by the embryo.
