HOW DO ORGANISMS REPRODUCE: Assertion-Reason Type Questions Class 10th Chapter 10 JKBOSE/NCERT
Assertion-Reason Type Questions
Question 1. ASSERTION: Gonorrhoea is a sexually transmitted disease.
REASON: It is caused by the virus.
Answer: False
Explanation: The assertion is true, as gonorrhoea is indeed a sexually transmitted disease. However, the reason is incorrect. Gonorrhoea is caused by the bacterium Neisseria gonorrhoeae, not a virus.
Question 2. ASSERTION: Ovary releases one egg every month.
REASON: The lining of the uterus is always thick and spongy.
Answer: False
Explanation: The assertion is true, as the ovary releases one egg every month during the menstrual cycle. However, the reason is incorrect. The lining of the uterus called the endometrium, undergoes cyclic changes during the menstrual cycle. It becomes thick and spongy in preparation for the potential implantation of a fertilized egg, but if fertilization does not occur, the lining is shed during menstruation.
Question 3. ASSERTION: Plants raised by vegetative propagation can bear flowers and seeds earlier than those produced from seeds.
REASON: Plants which have lost the capacity to bear viable seeds, can propagate through vegetative propagation.
REASON: Plants which have lost the capacity to bear viable seeds can propagate through vegetative propagation.
Answer: True
Explanation: The assertion is true. Plants raised through vegetative propagation, such as through techniques like cuttings or grafting, can indeed bear flowers and seeds earlier than those produced from seeds. The reason is also true, as some plants may have lost the ability to produce viable seeds due to various reasons like genetic modifications, hybridization, or other factors, but they can still be propagated through vegetative means.
Question 4. ASSERTION: In the male reproductive system, the transport of sperm takes place in a fluid which also provides nutrition.
REASON: The secretions of prostate glands and seminal vesicles constitute the semen.
Answer: True
Explanation: The assertion is true. The transport of sperm in the male reproductive system occurs in a fluid called semen. The reason is also true, as semen is composed of sperm cells along with secretions from the prostate glands and seminal vesicles. These secretions provide the necessary fluid and nutrients to support and nourish the sperm.
Question 5. ASSERTION: Amoeba reproduces by binary fission.
REASON: All unicellular organisms reproduce by asexual method
Answer: True
Explanation: The assertion is true. Amoeba, being a unicellular organism, reproduces by binary fission, where the parent cell divides into two daughter cells. The reason is also true, as most unicellular organisms reproduce by asexual methods, such as binary fission, budding, or fragmentation, where offspring are produced without the involvement of gametes or sexual reproduction.
