Which of the following statements is not correct about reproduction ?a...
Reproduction is a fundamental process in living organisms that ensures the continuity of a species. It involves the production of offspring, either by sexual or asexual means. However, the statement "Animals reproduce only by sexual mode of reproduction" is incorrect. Animals can reproduce through both sexual and asexual modes of reproduction.
Sexual reproduction, as the name suggests, involves the fusion of male and female gametes to produce offspring. This process leads to genetic variation and the production of unique individuals. It requires the involvement of two parents and results in offspring that inherit a combination of traits from both.
On the other hand, asexual reproduction involves the production of offspring without the involvement of gametes or the fusion of genetic material from two parents. It leads to the production of offspring that are genetically identical or very similar to the parent.
Here's a breakdown of the correct and incorrect statements:
a) Lot of energy is spent in reproduction - This statement is correct. Reproduction requires a significant amount of energy expenditure. Organisms need to allocate resources to produce gametes, find mates, and provide care for offspring.
b) Reproduction creates more individuals - This statement is correct. The primary purpose of reproduction is to produce offspring, thereby increasing the population of a species.
c) Animals reproduce only by sexual mode of reproduction - This statement is incorrect. Animals can reproduce through both sexual and asexual modes of reproduction.
d) Reproduction is not necessary to maintain the life of an individual - This statement is incorrect. While reproduction is not necessary for an individual's survival, it is essential for the survival of a species. Reproduction ensures the continuation of a species over generations.
In conclusion, the correct statement is option 'C': Animals reproduce through both sexual and asexual modes of reproduction.
