Question 1 of 17 Medium

Which of the following is a characteristic feature of monocot stems?

  1. A Scattered vascular bundles
  2. B Vascular bundles arranged in a ring
  3. C Presence of secondary growth
  4. D Presence of cambium

Correct answer: Scattered vascular bundles

In monocot stems, vascular bundles are scattered throughout the ground tissue. This arrangement is called atactostele.

Question 2 of 17 Medium

Which of the following is typical of dicot stems?

  1. A Scattered vascular bundles
  2. B Closed vascular bundles
  3. C Absence of cambium
  4. D Vascular bundles in a ring

Correct answer: Vascular bundles in a ring

Dicot stems have vascular bundles arranged in a ring. This allows for the presence of cambium and secondary growth.

Question 3 of 17 Medium

Which type of root system is commonly found in dicots?

  1. A Tap root system
  2. B Fibrous root system
  3. C Adventitious roots
  4. D Aerial roots

Correct answer: Tap root system

Dicot plants typically have a tap root system. It consists of a primary root and its lateral branches.

Question 4 of 17 Medium

Which type of root system is commonly found in monocots?

  1. A Fibrous root system
  2. B Tap root system
  3. C Prop root system
  4. D Buttress root system

Correct answer: Fibrous root system

Monocots usually have a fibrous root system. It consists of many thin roots arising from the base of the stem.

Question 5 of 17 Medium

Which feature distinguishes monocot leaves from dicot leaves?

  1. A Parallel venation
  2. B Reticulate venation
  3. C Broad lamina
  4. D Petiole present

Correct answer: Parallel venation

Monocot leaves typically show parallel venation. Dicot leaves usually have reticulate venation.

Question 6 of 17 Medium

Which type of venation is seen in dicot leaves?

  1. A Reticulate
  2. B Parallel
  3. C Dichotomous
  4. D Circular

Correct answer: Reticulate

Dicot leaves have reticulate venation, where veins form a network. This is a key identifying feature.

Question 7 of 17 Medium

Which of the following is true for dicot vascular bundles?

  1. A Closed bundles
  2. B Lack cambium
  3. C Scattered bundles
  4. D Open with cambium

Correct answer: Open with cambium

Dicot vascular bundles are open due to the presence of cambium. This enables secondary growth.

Question 8 of 17 Medium

Which of the following is absent in monocot stems?

  1. A Xylem
  2. B Phloem
  3. C Vascular bundles
  4. D Cambium

Correct answer: Cambium

Monocot stems lack cambium. Therefore, they do not show secondary growth.

Question 9 of 17 Medium

Which type of pith is found in dicot stems?

  1. A Completely absent from the stem
  2. B Small or absent
  3. C Well-developed central pith
  4. D Scattered pith

Correct answer: Well-developed central pith

Dicot stems have a well-developed central pith. It is surrounded by vascular bundles arranged in a ring.

Question 10 of 17 Medium

In monocot stems, ground tissue is:

  1. A Differentiated into cortex and pith
  2. B Undifferentiated
  3. C Absent
  4. D Only cortex present

Correct answer: Undifferentiated

Monocot stems have undifferentiated ground tissue. It is not clearly divided into cortex and pith.

Question 11 of 17 Medium

Which of the following features is typical of dicot roots?

  1. A Polyarch xylem
  2. B Few xylem bundles
  3. C Large pith
  4. D Scattered vascular bundles

Correct answer: Few xylem bundles

Dicot roots have fewer xylem bundles, often arranged in a star shape. The pith is small or absent.

Question 12 of 17 Medium

Which of the following is a feature of monocot roots?

  1. A Small pith
  2. B Star-shaped xylem
  3. C Large pith
  4. D Few xylem bundles

Correct answer: Large pith

Monocot roots have a large central pith. The vascular bundles are numerous and arranged in a ring.

Question 13 of 17 Medium

Which type of xylem arrangement is seen in dicot roots?

  1. A Polyarch
  2. B Radial with few arms
  3. C Scattered
  4. D Circular, multi-armed pattern

Correct answer: Radial with few arms

Dicot roots have radial xylem arrangement with a few arms. It often appears star-shaped.

Question 14 of 17 Medium

Which type of xylem arrangement is common in monocot roots?

  1. A Diarch
  2. B Triarch
  3. C Polyarch
  4. D Tetrarch

Correct answer: Polyarch

Monocot roots have polyarch xylem, meaning many xylem strands. This is a distinguishing feature.

Question 15 of 17 Medium

Which of the following is a key anatomical difference between monocot and dicot stems?

  1. A Presence of epidermis
  2. B Overall presence of vascular bundles
  3. C Arrangement of vascular bundles
  4. D Presence of xylem tissue

Correct answer: Arrangement of vascular bundles

The arrangement of vascular bundles differs: scattered in monocots and in a ring in dicots. This is a major distinguishing feature.

Question 16 of 17 Medium

Which of the following plants shows secondary growth?

  1. A Barley
  2. B Sorghum
  3. C Sunflower
  4. D Sugarcane

Correct answer: Sunflower

Sunflower is a dicot and shows secondary growth due to the presence of cambium. Monocots generally lack this ability.

Question 17 of 17 Medium

Which type of leaf anatomy is typical of dicots?

  1. A Isobilateral
  2. B Dorsiventral
  3. C Parallel
  4. D Symmetrical

Correct answer: Dorsiventral

Dicot leaves are dorsiventral, with distinct upper and lower surfaces. This helps in efficient photosynthesis.
