Question

The events in pollen-pistil interaction are given below (i) Pollen grain germinates to form pollen tube (ii) Pollen tube enters the ovule through micropyle (iii) Pollen grain reaches the stigma (iv) Pollen tube grows through the tissues of stigma and style and reaches the ovary The sequential order of their occurence is (A) (iii) → (i) → (iv) → (ii) (B) (ii) → (iv) → (iii) → (i) (C) (iii) → (iv) → (ii) → (i) (D) (ii) → (iii) → (i) →(iv)

Tardigrade Admin · Accepted Answer

Correct answer is (a) (iii) → (i) → (iv) → (ii)

$(iii) \to (i) \to (i v) \to (ii)$

$(ii) \to (i v) \to (iii) \to (i)$

$(iii) \to (i v) \to (ii) \to (i)$

$(ii) \to (iii) \to (i) \to (i v)$

Correct answer is (a) $(iii) \to (i) \to (i v) \to (ii)$

(iii)→(i)→(iv)→(ii)

(ii)→(iv)→(iii)→(i)

(iii)→(iv)→(ii)→(i)

(ii)→(iii)→(i)→(iv)

Correct answer is (a) (iii)→(i)→(iv)→(ii)

$(iii) \to (i) \to (i v) \to (ii)$

$(ii) \to (i v) \to (iii) \to (i)$

$(iii) \to (i v) \to (ii) \to (i)$

$(ii) \to (iii) \to (i) \to (i v)$

Correct answer is (a) $(iii) \to (i) \to (i v) \to (ii)$
