1. Multiple choice questions.


Q1. Which one of the following pairs is correct regarding different types of tissues and their function?


  • (a) Collenchyma – Mechanical support to growing parts
  • (b) Parenchyma – Conduction of food
  • (c) Sclerenchyma – Photosynthesis
  • (d) Meristem – Storage of food

Answer: (a) Collenchyma – Mechanical support to growing parts


Q2. In which part of the flower is the ovule found?


  • (a) Stigma
  • (b) Style
  • (c) Ovary
  • (d) Anther

Answer: (c) Ovary


Q3. Which tissue is responsible for the transportation of water in plants?


  • (a) Phloem
  • (b) Xylem
  • (c) Collenchyma
  • (d) Parenchyma

Answer: (b) Xylem


Q4. Identify the correct inflorescence type for the following description: The main axis continues to grow and the flowers are borne laterally in acropetal succession.


  • (a) Racemose
  • (b) Cymose
  • (c) Capitulum
  • (d) Cyathium

Answer: (a) Racemose


Q5. Which animal tissue forms the inner lining of the digestive tract?


  • (a) Connective tissue
  • (b) Muscular tissue
  • (c) Epithelial tissue
  • (d) Nervous tissue

Answer: (c) Epithelial tissue


2. Very Short Answer (VSA).


Q1. Define parenchyma tissue in plants.


Answer: Parenchyma is a simple permanent tissue in plants, made of living thin-walled cells. It performs photosynthesis, storage, and secretion.


Q2. What is the function of stomata?


Answer: Stomata regulate the exchange of gases and control transpiration by opening and closing their pores in the epidermis of leaves.


Q3. Name the male reproductive organ in a frog.


Answer: The male reproductive organ in frog is the testis, which produces sperm cells.


Q4. What is a racemose inflorescence?


Answer: Racemose inflorescence is where the main axis continues to grow and flowers develop laterally in acropetal succession.


Q5. Mention one feature of malvaceae family.


Answer: Plants in the Malvaceae family often have mucilaginous sap and monadelphous stamens (filaments united into a tube).


3. Short Answer Questions.


Q1. Describe the different types of animal tissues found in frogs, mentioning their main functions.


Answer: Frogs possess four main animal tissues: epithelial (lining and protection), connective (support, e.g., bone and cartilage), muscular (movement), and nervous (control and coordination). Each tissue type has specialized cells suited for its function, enabling vital processes like contraction, defense, and impulse conduction.


Q2. Explain the process of secondary growth in dicot stems.


Answer: Secondary growth in dicot stems involves the formation of secondary vascular tissues by the vascular cambium. This increases stem thickness, producing secondary xylem (wood) on the inside and secondary phloem on the outside, strengthening the plant and allowing increased transport and support.


Q3. State the differences between monocot and dicot root anatomy.


Answer: Monocot roots have large pith, many xylem and phloem bundles (polyarch), and no secondary growth. Dicot roots have less developed pith, few vascular bundles (tetrarch, pentarch), and undergo secondary growth due to the presence of cambium.


Q4. Write the main morphological features of the Cruciferae family and give one example.


Answer: Cruciferae have herbaceous habit, alternate or radical leaves, tetradynamous stamens, cruciform corolla and siliquae fruit. Example: Brassica (mustard).


Q5. Describe the structure and function of sclerenchyma tissue.


Answer: Sclerenchyma consists of dead, thick-walled cells with lignified walls. They provide mechanical support to plants, found in hard parts like seed coats, nutshells, and fibers.


4. True or False Questions.


Q1. In monocot stems, vascular bundles are closed and scattered.


Answer: True


Q2. Xylem transports food from leaves to other parts.


Answer: False


Q3. In frogs, the respiratory system consists of lungs, skin, and buccal cavity.


Answer: True


Q4. Leguminoceae family plants have a zygomorphic flower symmetry.


Answer: True


Q5. Collenchyma tissue consists of dead cells only.


Answer: False


3. Fill in the Blanks Questions.


Q1. The tissue responsible for the conduction of organic food in plants is __________.


Answer: Phloem


Q2. The main function of root hairs is __________.


Answer: Absorption of water and minerals


Q3. The connective tissue which stores fat in animals is called __________ tissue.


Answer: Adipose


Q4. In frogs, blood is transported through __________ system.


Answer: Circulatory


Q5. __________ inflorescence has the main axis ending in a flower and further growth is continued by lateral branches.


Answer: Cymose

FAQs on Structural Organisation In Animals And Plants Important Questions for NEET Biology - 2026

1. What are the most important NEET questions from 'Structural Organisation In Animals And Plants'?

NEET often asks about tissues, morphology of flowering plants, and anatomy of systems in animals like frogs. Focus on questions about tissue types, modifications of roots, stems, and leaves, as well as practical aspects, including identification and functions of plant and animal parts.

2. Which chapter areas see frequent assertion-reason or statement-based NEET questions?

Assertion-reason types are commonly asked on differences between plant tissue types, plant modifications, and characteristics of animal tissues or frog anatomy. Practice distinguishing functions and features to answer these effectively.

3. How should I revise NEET MCQs on plant morphology and modifications for this chapter?

Start by categorizing MCQs by root, stem, and leaf modifications. Use diagrams where possible and practice matching column or diagram-based MCQs. Summarize each part’s function as you revise.

4. What practice tips help with exam-focused questions about animal tissues and frog anatomy?

First, memorize key points on simple vs. complex tissues and frog body systems (digestive, circulatory, etc.). Quiz yourself on structure-function relationships. For each system, list the main organs and their roles briefly.

5. Are family classification and examples important for NEET chapter-wise practice?

Yes, NEET often asks MCQs on plant families like Malvaceae, Leguminosae, Cruciferae. Know their characteristic features and example species. Making a table of important families and their unique features is very helpful for revision.

6. How are diagram-based NEET questions framed from this chapter?

Expect diagrams of plant tissues, modified structures, and frog internal organs. Usually, you’ll need to label parts or match features to names. Practice drawing simple diagrams and identify the labelled structures after revising each section.

7. What common mistakes do students make while answering NEET important questions from this topic?

The major pitfalls are mixing up tissue types, confusing plant tissue locations, and missing differences between plant and animal systems. Review definitions, practice matching questions, and regularly test yourself with sample MCQs to avoid these errors.
