What the Plant Growth and Development Exemplar Covers

The Exemplar tests the same chapter as the textbook but at a higher level of difficulty. Its questions probe common traps in the phases of growth, the plant growth regulators, and the responses of photoperiodism and vernalisation. Because Chapter 13 pairs each hormone with its effect, the Exemplar spends its questions checking whether students can match a growth regulator to its role, tell differentiation from dedifferentiation, and read a growth curve and its rate correctly.

• Growth, the phases and rate of growth, arithmetic and geometric growth, and the sigmoid growth curve.
• Differentiation, dedifferentiation and redifferentiation, development, and the ideas of plasticity.
• The five plant growth regulators (auxins, gibberellins, cytokinins, ethylene and abscisic acid), photoperiodism, vernalisation and seed dormancy.

Why Practise the Exemplar for This Chapter

The Exemplar bridges the gap between the NCERT textbook and the level of a competitive exam. For plant growth, its questions are close to the style asked in NEET and CUET, where a single detail about apical dominance or the hormone behind bolting can decide a mark. Because Chapter 13 is a set of hormone-effect pairs and responses, the Exemplar is where students find the tricky assertion-reason sets and the well-framed MCQs that a plain reading of the textbook rarely throws up.

• Higher-order questions that the textbook exercises do not cover.
• Assertion-reason sets that sharpen your grip on plant growth regulators.
• MCQs on photoperiodism, vernalisation and growth phases at exam level.

How to Use the Exemplar for Plant Growth and Development

Attempt the Exemplar only after you have finished the NCERT textbook chapter and its back exercises. Treat it as your second, harder pass over the chapter. Because much of this chapter is hormones paired with their effects, students gain the most by making a table of each regulator and its role rather than only marking the option, so the pairings stay fixed in memory for the exam.

• Solve the MCQs first to test recall, then move to assertion-reason.
• Attempt each short and long answer fully before checking the Exemplar Solutions.
• Mark the questions you got wrong and redo them after two days.
• Keep a table of the five plant growth regulators and their functions handy while you practise.

Use the Exemplar with the textbook PDF, the solved answers, the revision notes and the formula sheet for the same chapter. Working across all the resources gives students the definitions, the practice and the higher-order questions they need for both the CBSE board exam and NEET.

Student Feedback on the Plant Growth and Development Exemplar

More than 10,000 Class 11 students used these Collegedunia NCERT resources during the 2026 boards and NEET preparation. Their feedback shaped how we present this chapter, and the message on Chapter 13 was consistent: the Exemplar is what turns a set of hormone-effect pairs into exam-ready recall.

• Students rated the assertion-reason sets as the most useful part for fixing plant growth regulators.
• Many said the Exemplar MCQs on photoperiodism and vernalisation matched the NEET questions they later saw.
• Students preparing for CUET found the short-answer terms a fast way to revise the whole chapter.
