NCERT Class 10 Science Chapter 7 How do Organisms Reproduce? Test Mock Test
This free online test covers Chapter 7, How do Organisms Reproduce?, from the NCERT Class 10 Science textbook. The 29 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.DNA copying during reproduction is accompanied by the creation of additional cellular apparatus because:
- AA DNA copy simply pushed out of the cell would have no organised cellular structure to maintain life processes
- BThe cell must double its size before it can divide
- CCellular apparatus is needed to make the DNA copy in the first place
- DThe two DNA copies would otherwise fuse back into a single molecule
Q2.Variations arise during reproduction because:
- AThe cellular apparatus alters the DNA once the copy has been made
- BCells deliberately introduce changes into the DNA to help the species survive
- CEvery daughter cell receives only half of the parent cell's DNA
- DNo bio-chemical reaction is absolutely reliable, so the process of copying DNA has some variations each time
Q3.The chapter's example of bacteria living in temperate waters that are warmed by global warming is used to show that:
- APopulations without any variation survive changes in their niche best
- BVariation always benefits every individual in the population equally
- CA change in temperature can by itself create new variants in a population
- DVariation is useful for the survival of a species over time, since a few resistant variants can survive a drastic change in the niche
