Q2. Which of the following is correct about growth pattern in plants and animal cells?

  1. (a) Animal cells growth is due to meristematic tissues.
  2. (b) Plant cell growth is more uniform in comparison to animal cells.
  3. (c) Plants have a specific growth region containing dividing tissues.
  4. (d) Both follow same growth pattern.
Answer & solution

Answer: (c) Plants have a specific growth region containing dividing tissues.

Correct Answer:
Correct Answer: Option 3 – Plants have a specific growth region containing dividing tissues.
Explanation:
Unlike animals, plants havelocalized regions of growth(calledmeristematic tissue) at the tips of roots and shoots, where active cell division occurs throughout the plant's life. In contrast, animal growth occurs relatively uniformly across the body and stops after a certain stage, without such fixed dividing regions.
Important Facts:
• Meristematic tissue is exclusive to plants, not animals.
• Plant growth is often described as 'indeterminate' (continues throughout life) at these meristems.
• Animal cell growth involves cell division throughout the body during development, not confined to specific zones.

Q3. Which of the following explains why epithelial tissue cells are tightly packed with very little space between them?

  1. (a) To form a continuous barrier and regulate permeability
  2. (b) To enhance secretion functions of the tissue
  3. (c) To allow rapid cell division in the tissue
  4. (d) To increase the overall strength of the tissue
Answer & solution

Answer: (a) To form a continuous barrier and regulate permeability

Correct Answer:
Correct Answer: Option 1 – To form a continuous barrier and regulate permeability
Explanation:
Epithelial tissue cells are packed tightly with almost no intercellular space between them because their main function is tocover and protectbody surfaces and line cavities/organs, forming a continuous, unbroken sheet/barrier. This tight packing allows the tissue toregulate what passes through it(selective permeability) — for example, protecting underlying tissues from pathogens, injury, and desiccation while controlling absorption and secretion at specific sites.

RRB Group D 2025-26 – 18 August 2026 Shift 3 · Connective tissue (blood, bone, cartilage, ligament, tendon)

Q8. A football player tears a structure that connects muscles to bones during practice. Which structure is most likely damaged?

  1. (a) Tendon
  2. (b) Ligament
  3. (c) Nerve
  4. (d) Cartilage
Answer & solution

Answer: (a) Tendon

Concept: Connective Tissues — Tendon vs Ligament
• Tendon: connectsmuscle to bone; transmits the force of muscle contraction to move the bone.
• Ligament: connectsbone to boneat a joint, providing stability.
• Nerve: transmits electrical impulses, not a mechanical connector.
• Cartilage: a flexible connective tissue found at joints/ends of bones, not a muscle-bone connector.
Since the injury described involves the structure connecting muscle to bone, it is the tendon that is torn.

  2. (b) Lignin
  3. (c) Suberin
  4. (d) Cellulose
Answer & solution

Answer: (c) Suberin

Correct Answer: Suberin — Option (c)
Cork cells (part of the periderm/bark of older plant stems and roots) have their cell walls impregnated with Suberin, a complex waxy, hydrophobic polymer. Suberin makes cork cells completely impermeable to water and gases. Once the cell wall is suberized, the cell contents die and the cell becomes an air-filled, dead protective layer. This is why cork is used as a sealant (e.g., bottle stoppers).
Option (a) Cutin — Incorrect: Cutin is found in the cuticle of the leaf epidermis, not in cork cells.
Option (b) Lignin — Incorrect: Lignin provides mechanical strength to xylem cells but does not make cork cells impermeable.

The correct answer is 3 (Option 2). Meristematic tissue is classified into three types based on position: (1) Apical meristem – present at the tips of roots and shoots, responsible for primary growth; (2) Lateral meristem – present on the sides, responsible for increase in girth (e.g., cambium); (3) Intercalary meristem – present at the base of internodes, responsible for elongation. Option 1 (2 types) and Options 3 and 4 (4 or 5 types) are incorrect.
SSC MTS 2025 – 5 February 2026 Shift 3 · Meristematic tissues

Q89. _____ is present at the growing tips of stems and roots and increases the length of the stem and the root.

  1. (a) Apical meristem
  2. (b) Parenchyma tissue
  3. (c) Intercalary meristem
  4. (d) Lateral meristem
Answer & solution

Answer: (a) Apical meristem

Correct Answer: Apical meristem
Apical meristem is a type of meristematic tissue (actively dividing cells) located at the growing tips (apex) of stems and roots. It is responsible for primary growth - the increase in the length of the plant. Root apical meristem increases root length and shoot apical meristem increases stem length.
Why other options are wrong:
Parenchyma tissue - A permanent tissue; not a meristem; fills spaces in the plant body.
Intercalary meristem - Located near nodes (internodes) in grasses; not at tips.
Lateral meristem - Located on the sides of stems/roots; responsible for increase in girth (secondary growth), not length.
SSC MTS 2025 – 5 February 2026 Shift 3 · Meristematic tissues

Q90. In which part of the plant is the intercalary meristem typically located?

  1. (a) At the root tip
  2. (b) Near the node
  3. (c) In the leaves
  4. (d) At the base of the flower
Answer & solution

Answer: (b) Near the node

Correct Answer: Near the node
Intercalary meristem is located at the base of internodes or near the nodes (leaf attachment points) in grasses and other monocots. It allows grasses to regrow rapidly after being cut or grazed, since the growing region is at the base rather than the tip.
Why other options are wrong:
Root tip - The root tip contains the apical meristem, not intercalary meristem.
In the leaves - Leaves do not contain intercalary meristem.
At the base of flower - Flowers do not have intercalary meristem.

Q91. Which of the following is a characteristic feature of meristematic tissues in plants?

  1. (a) Dead cells that provide mechanical support
  2. (b) Absence of nucleus and presence of lignified walls
  3. (c) Large vacuoles and thick cell walls
  4. (d) Actively dividing cells with dense cytoplasm and prominent nuclei
Answer & solution

Answer: (d) Actively dividing cells with dense cytoplasm and prominent nuclei

The correct answer is option 4. Meristematic tissues are composed of actively dividing cells that are responsible for plant growth. These cells have dense cytoplasm, thin cell walls, small or absent vacuoles, and prominent nuclei . Their constant division adds new cells, enabling plants to grow in length (apical meristem), thickness (lateral meristem), and secondary structures. In contrast, dead cells with lignified walls and large vacuoles are features of permanent tissues like xylem and sclerenchyma, not meristematic tissues.
SSC CHSL Tier-1 2025 – 26 November 2025 Shift 2 · Permanent plant tissues (simple and complex)
