Epigeal germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. Bean, cotton, papaya, gourd, castor and onion have germination of this kind.

Hypogeal germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil. Pea, mango, maize, rice, gram and groundnut have germination of this kind. So, the correct answer is 'Pea'.

A. Zea mays (Maize) - hypogeal germination.

B. Helianthus (Sunflower) - epigeal germination.

C. Mangifera (Mango)- hypogeal germination.

D. Pisum (Pea)- hypogeal germination.

So, the correct answer is 'Helianthus'.

Epigeal germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. Bean, cotton, papaya, gourd, castor and onion have germination of this kind.

Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil. Pea, mango, maize, rice, gram and groundnut have germination of this kind. So, the correct answer is 'Castor'.

A. Vivipary :  In plants, vivipary (precocious or premature germination) involves the germination of seeds while still on the parent plant. It is a widespread phenomenon in plants characterized by the lack of seed dormancy. 

C. Monocarpic- flowering only once.

D. Vernalisation- The cooling of seed during germination in order to accelerate flowering when it is planted.

E. Seismonasty is the nastic response of a plant or fungus to touch or vibration.

So, the correct answer is 'Vivipary'.

A. Pods develop underground, an unusual feature known as geocarpy. After fertilization, a short stalk at the base of the ovary (termed a pedicel) elongates to form a thread-like structure known as a "peg". This peg grows down into the soil, and the tip, which contains the ovary, develops into a mature peanut pod.

B. Achene- A small, indehiscent, one seeded fruit developing from a monocarpellary ovary and in which pericarp is hard, leathary and remains free from seed coat. E.g. Mirabilis.

C. Caryopsis- A small, indehiscent, one seeded fruit developing from a monocarpellary ovary and in which pericarp is fused with the seed coat. E.g. Wheat.

D. Drupe- A small, indehiscent, one seeded fruit developing from a monocarpellary ovary and in which pericarp is differentiated into outer,thin epicarp, middle fleshy and fibrous mesocarp and inner hard and stony endocarp. E.g. Mango. So, the correct answer is 'Pod'.

In this type of germination, the epicotyl elongates and the cotyledons remain below the soil. Pea, mango, maize, rice, gram and groundnut have germination of this kind. So, the correct answer is 'Epicotyl'.
