Biology Chapter 9 : Topic 5

Parthenogenesis

1 / 15

Parthenogenesis is a process in which:

A) Two gametes fuse to form zygote

B) Buds form on parent body

C) Spores are produced in fungi

D) An egg develops into a new organism without fertilization

2 / 15

Parthenogenesis is considered asexual reproduction because:

A) It produces genetic variation

B) It always involves two organisms

C) It involves fertilization

D) It produces offspring from a single parent without gamete fusion

3 / 15

Which of the following organisms commonly show parthenogenesis?

A) Honeybee

B) Hydra

C) Fern

D) Amoeba

4 / 15

In parthenogenesis, the offspring are generally:

A) Produced from unfertilized egg cells

B) Genetically identical to both parents

C) Produced without any genetic material

D) Always genetically different

5 / 15

Which statement best supports parthenogenesis as asexual reproduction?

A) It always produces seeds

B) It does not involve fusion of gametes

C) It involves meiosis and fertilization

D) It requires two parents

6 / 15

The male honeybee (drone) is produced by:

A) Budding

B) Fertilized egg

C) Spore formation

D) Parthenogenesis

7 / 15

Parthenogenesis differs from sexual reproduction because it:

A) Does not involve male gametes

B) Increases variation

C) Requires fertilization

D) Always involves two parents

8 / 15

Which of the following is NOT involved in parthenogenesis?

A) Fertilization

B) Embryo development

C) Egg cell

D) Single parent

9 / 15

Parthenogenesis can be best described as:

A) Formation of spores

B) Asexual development of embryo from an unfertilized egg

C) Sexual reproduction with variation

D) Budding in yeast

10 / 15

Which is a key feature of parthenogenesis?

A) Development from unfertilized egg

B) Always produces identical twins

C) Occurs only in plants

D) Requires sperm and egg fusion

11 / 15

Why is parthenogenesis classified as asexual reproduction?

A) Because it involves meiosis and fertilization

B) Because a new organism arises from a single parent without fertilization

C) Because it always involves spores

D) Because it produces seeds

12 / 15

In parthenogenesis, genetic variation is generally:

A) Always maximum

B) Unrelated to reproduction

C) Very high

D) Completely absent or very low

13 / 15

Which of the following best distinguishes parthenogenesis from budding?

A) Parthenogenesis occurs in Hydra only

B) Budding occurs in bees

C) Parthenogenesis involves eggs, budding involves outgrowths

D) Both involve fertilization

14 / 15

Parthenogenesis is important in nature because it:

A) Requires two parents for survival

B) Produces only spores

C) Prevents reproduction

D) Allows reproduction without fertilization in certain conditions

15 / 15

Which statement best rationalizes parthenogenesis as asexual reproduction?

A) It occurs only in plants

B) It requires male and female gametes

C) It produces offspring from unfertilized egg without gamete fusion

D) It always increases variation
