* Apomixis and Polyembryony

1. The polyembryony commonly occurs in.

(A) tomato
(B) potato
(C) Citrus
(D) turmeric

2. Adventive embryonic in Citrus is due to

(B) integuments
(C) zygotic embryo
(D) fertilized egg

3. In a type of apomixis known as adventive embryonic, embryos develop directly from the

(A) nucellus or integuments
(B) zygote
(C) synergids or antipodals in an embryo sac
(D) accessory embryo sacs in the ovule

4. Apomictic embryos in Citrus arise from

(A) synergids
(B) maternal sporophytic tissue in ovule
(C) antipodal cells
(D) diploid egg

5. common What is between vegetative reproduction and apomixis?

(B) Both bypass the flowering phase
(C) Both occur round the year
(D) Both produce progeny identical to the parent

6. Nucellar polyembryony is reported in species of

(A) Citrus
(B) Gossypium
(C) Triticum
(D) Brassica

7. The hilum is a scar on the

(A) Seed, where funicle was attached
(B) Fruit, where it was attached to the pedicel
(C) Fruit, where style was present
(D) Seed, where micropyle was present

8. Seed formation without fertilization in flowering plants involves the process of

(A) Somatic hybridization
(B) Apomixis
(C) Sporulation
(D) Budding

9. The body of the ovule is fused within the funicle at:
