  4. D Fig

Correct answer: Mango

Mango is a simple fruit that develops from a single ovary of a single flower. It is a drupe.

Question 4 of 20 Medium

Which type of fruit develops from a multicarpellary syncarpous ovary?

  1. A Simple fruit
  2. B Aggregate fruit
  3. C Multiple fruit
  4. D False fruit

Correct answer: Simple fruit

Simple fruits can develop from a multicarpellary syncarpous ovary. The carpels are fused into one structure.

Question 5 of 20 Medium

Which of the following is an example of an aggregate fruit?

  1. A Watermelon

Which of the following is a multiple fruit?

  1. A Mango
  2. B Pineapple
  3. C Watermelon
  4. D Pea

Correct answer: Pineapple

Pineapple is a multiple fruit formed from an entire inflorescence. Individual flowers fuse together.

Question 7 of 20 Medium

Which part of the pericarp is the innermost layer?

  1. A Epicarp
  2. B Mesocarp
  3. C Endocarp
  4. D Exocarp

Correct answer: Endocarp

The endocarp is the innermost layer of the pericarp. It may be hard as in mango or soft as in tomato.

Question 8 of 20 Medium

Which type of fruit is fleshy throughout the pericarp?

  1. A Drupe
  2. B Berry
  3. C Capsule
  4. D Legume

Correct answer: Berry

In berries, the entire pericarp is fleshy. Examples include tomato and grape.

Question 9 of 20 Medium

  1. A Berry
  2. B Drupe
  3. C Capsule
  4. D Achene

Correct answer: Drupe

Drupes like mango and coconut have a hard endocarp. It protects the seed inside.

Question 10 of 20 Medium

Which type of fruit splits open to release seeds?

  1. A Indehiscent fruit
  2. B Dry indehiscent fruit
  3. C Dry dehiscent fruit
  4. D Aggregate fruit

Correct answer: Dry dehiscent fruit

Dry dehiscent fruits split open at maturity to release seeds. Examples include legumes and capsules.

Question 11 of 20 Medium

Which of the following is an indehiscent fruit?

  1. A Pea
  2. B Capsule
  3. C Achene
  4. D Follicle

Correct answer: Achene

Indehiscent fruits like achene do not split open at maturity. The seed remains enclosed.

Question 12 of 20 Medium

Which fruit is formed without fertilization?

  1. A True fruit
  2. B Parthenocarpic fruit
  3. C Aggregate fruit
  4. D Multiple fruit

Correct answer: Parthenocarpic fruit

Parthenocarpic fruits develop without fertilization. They are usually seedless, like banana.

Question 13 of 20 Medium

Which method of seed dispersal involves wind?

  1. A Hydrochory
  2. B Zoochory
  3. C Anemochory
  4. D Autochory

Correct answer: Anemochory

Anemochory is dispersal by wind. Seeds are light or have wings or hairs for easy transport.

Question 14 of 20 Medium

Which fruit is adapted for water dispersal?

  1. A Coconut
  2. B Mango
  3. C Pea
  4. D Sunflower

Correct answer: Coconut

  1. A Anemochory
  2. B Hydrochory
  3. C Autochory
  4. D Zoochory

Correct answer: Zoochory

Zoochory involves dispersal by animals. Seeds are spread after being eaten or carried.

Question 16 of 20 Medium

Which fruit is classified as a legume?

  1. A Mango
