Epicotyl has a shoot apex and a few leaf primordial enclosed in a hollow foliar structure called as the:

(1) Coleoptile

(2) Coleorhiza

(3) Scutellum

(4) Perisperm

Identify the different parts of a typical dicot embryo labeled as A, B and C and select the correct option.

Diagram given below shows stages in embryogenesis in a typical dicot (Capsella). Identify structures A to D respectively:

1. Suspensor, Radicle, Plumule, Cotyledons
2. Hypophysis, Radicle, Plumule, Cotyledons
3. Suspensor, Plumule, Radicle, Cotyledons
4. Suspensor, Radicule, Plumule, Hypocotyls

Go through the given diagram of a typical dicot embryo. In which of the following all the 3 parts labelled as A, B, C with their respective functions are correctly identified?

Which of the following is not correct?
(1) As the seed matures, its water content is reduced and seeds become relatively dry(10-15% moisture by mass)

(2) The seed dormancy is the internal or innate inhibition of generation of normal or viable seeds

(3) Embryo in dormant seed shows higher rate of general metabolic rate

(4) Because of dormancy seeds remain viable for longer period and can be stored

The arrangement of the nuclei in a normal embryo sac in the dicot plants is:

1. 2+4+2

2. 3+2+3

3. 2+3+3

4. 3+3+2

In a cereal grain, the single cotyledon of the embryo is represented by:

1. coleorhiza

2. scutellum

3. prophyll

4. coleoptiles
