Question

Which of the following have two seeds leaves?
A.Rice
B.Maize
C.Green gram
D.None of these

Answer 1

Hint:The cotyledon the first leaf produced by the plant. Cotyledons are not considered as the true leaves but are called seed leaves since they are actually part of the seed and the embryo of the plant. Plants whose embryos have a single cotyledon are grouped as monocots and embryos with two cotyledons are grouped as dicots.

Complete answer:Cotyledons are defined as the embryonic leaf structures which give rise to plumule and radical which in turn give rise to the shoot and root of the plant. These are generally present in seed-bearing plants.
The prominent role of cotyledons or seed leaves is to provide nutrition to the germinating seed until the true leaves of the plant do not start synthesizing their own food through photosynthesis.
Maize and rice are monocots having one seed leaf or cotyledon in their seeds. Green grams are dicotyledons and have two seed leaves in their seeds.
So the correct answer is (option C), green gram.

Additional information:
In monocots, the petals are in multiples of 3, whereas in dicots the petals are in multiples of 4 or 5.
In monocots, fibrous roots are seen whereas in dicots taproots are seen.

Note:Dicots have two seed halves inside the seed coat. They are usually rounded and fat because they contain the endosperm to feed the embryo plant when a monocot seed germinates it produces a single leaf. It is usually long and narrow like the adult leaf.
