9. What is a seed?
A seed is an embryonic plant enclosed in a
protective outer covering, along with a
food reserve. The formation of the seed is
a part of the process of reproduction in
seed plants, the spermatophytes,
including the gymnosperm and
angiosperm plants.
10. A Seed is primarily of two
types.
The two types are:
Monocotyledonous Seed.
Dicotyledonous Seed.
11. Monocotyledonous Seed.
A monocotyledonous seed has embryos that
possess only one large cotyledon called
scutellum. Generally, the scutellum is shaped
like a shield. It is located laterally towards the
side of the embryo axis.
Wheat, corn, millet, lilies, sugarcane, banana, onions,
ginger, palm, and bamboo.
14. Dicotyledonous Seed.
Dicot seeds(Dicotyledons) are the seeds which
have two embryonic leaves and cotyledons.
They are one of the two groups into which all
the flowering plants were divided.
Examples of Dicot Seeds: Bitter gourd seeds, Castor seeds, Mango seeds,
Neem Seeds, Night Jasmine seeds, Papaya seeds and Tamarind seeds.
18. When a monocot seed
germinates, it produces a
single leaf. It is usually long and
narrow, like the adult leaf. Even
when it is quite a round shape,
there is only one seed leaf in a
monocot. When a dicot
germinates, it produces two
seed leaves.
