Answer
a)K - seed coat / testa;
L - Cotyledon;
M - hypocotyls;
Rej. Wrong spelling
b)i)Epigeal germination;
ii)-protects plumule or shoot tip by penetrating through the soil in a curved manner;
-pulls the cotyledons out of the soil;
iii)It carries out photosynthesis providing food to the shoot and radical; (before the foliage leaves start to photosynthesis)
c) Absorption of water and mineral salts;
d) Hypogeal germination;
