Answer 1

Answer:

(iv)=>(ii)=>(i)=>(iii)

Explanation:

Plumule=>Epicotyl=>Hypocotyl=>Radicle

Answer 2

(d) Plumule - (b) epicotyl - (a) hypocotyl - (c) radicle are the correctly arranged from top to base of a dicot seed.

Explanation:

• Plumule - The primary bud of a plant embryo, consisting of leaves and an epicotyl, which is normally found at the apex of the hypocotyl.
• Epicotyl - The epicotyl is the part of the embryonal axis that is above the cotyledon in a dicot embryo. It comes to an end with the plumule.
• Hypocotyl - The hypocotyl is the part of the embryonal axis that is below the cotyledon in a dicot embryo. It comes to an end with the radicle.
• Radicle - When a seed germinates, the primary root or radicle, is the first organ to develop. It anchors the seedling by growing downward into the earth.
