Germination is hypogeal in

  1. Cotton

  2. Pea

  3. Castor

  4. Bean
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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'.

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'.

Multiple choice biology seeds - structure and germination germination seed germination the flower

In some halophytes, seeds germinate within fruits while attached to parent plant. The phenomenon is

  1. Vivipary

  2. Monocrapic

  3. Vernalisation

  4. Seismonasty

  5. Both A and B
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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'.

Fruit of peanut is

  1. Pod

  2. Achene

  3. Caryopsis

  4. Drupe
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

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'.

Terminator gene

  1. Helps in terminating flowering

  2. Helps in terminating seed germination

  3. Used in hybridisation

  4. None of the above.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Terminator genes are genetic modifications designed to prevent seeds from germinating in subsequent generations, effectively forcing farmers to buy new seeds.

In hypogeal germination, plumule comes out of ground due to elongation of

  1. Hypocotyl

  2. Epicotyl

  3. Cotyledons

  4. Both A and B
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

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'.

Which of the following comes first out of the soil in the bean seed?

  1. Hypocotyl

  2. Radicle

  3. Leaf foliage

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
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.
So the correct option is 'Hypocotyl'.
