One of the stages in seed germination is the Activation-Imbibition of water. Arrange the process accordingly starting from the water imbibition by seed. I. Seed become hydrate. II. Synthesis of new enzyme. III. Enzyme activity begin immediately. IV. Water soften seed coat to hydrate protoplasm.

A	I, II, III and IV
B	II, III, I and IV
C	I, IV, III and II
D	II, I, III and IV

Explanation:

Detailed explanation-1: -Imbibition: water fills the seed. The water activates enzymes that begin the plant’s growth. The seed grows a root to access water underground. The seed grows shoots that grow towards the sun. The shoots grow leaves and begin photmorphogenesis.

Detailed explanation-2: -The imbibition of water by seeds before germination can be divided into three phases: rapid uptake of water (phase I), phase of enhanced water uptake (phase II), and uptake of water along with the initiation of growth (phase III).

Detailed explanation-3: -Such five changes or steps occurring during seed germination are: (1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators and (5) Development of Embryo Axis into Seedling.
