Additional Resources to Improve Your Preparation

1. Practise Quizzes and Sample Questions
   Regular quizzes help you gauge your progress. Here is a quick sample quiz covering a few basic Biology concepts:

Sample Quiz

• Which organelle is known as the ‘powerhouse of the cell’?
  A. Golgi apparatus
  B. Nucleus
  C. Mitochondria
  D. Ribosome
  Answer: C. Mitochondria
  Explanation: Mitochondria generate ATP, the energy currency of the cell.

• Which among the following is not a greenhouse gas?
  A. Carbon dioxide
  B. Methane
  C. Water vapour
  D. Hydrogen gas
  Answer: D. Hydrogen gas
  Explanation: Hydrogen gas does not trap heat in the atmosphere like CO2, CH4, and H2O vapour do.

• Which process refers to the loss of water vapour from the aerial parts of plants?
  A. Transpiration
  B. Photosynthesis
  C. Respiration
  D. Excretion
  Answer: A. Transpiration
  Explanation: Transpiration primarily occurs through the stomata in leaves.

2. Attempting such questions regularly will help you work towards 100 biology questions and answers, ensuring thorough revision and practice.

3. Simple Mnemonic to Remember Taxonomy Levels
   One commonly used mnemonic for the hierarchical classification (Kingdom, Phylum, Class, Order, Family, Genus, Species) is:

“King Philip Came Over For Great Soup.”

• King → Kingdom

• Philip → Phylum

• Came → Class

• Over → Order

• For → Family

• Great → Genus

• Soup → Species

4. Using such memory aids can make complex Biology concepts easier to recall during exams.

5. Tips for Effective MCQ Practice

• Read the question carefully and understand what is being asked.

• Eliminate wrong options.

• Review your textbook or class notes for detailed explanations of each concept.

• Practise NEET biology MCQ chapter-wise if you are preparing for NEET or similar entrance tests.

• Look for NEET biology MCQ with answers to identify where you make mistakes and rectify them immediately.
