  • Question 2
    1 / -0
    Select the correct combination of inflorescences.
    Solution
    A. Simple raceme, corymb, and umbel belong to racemose inflorescence. Simple cyme belongs to cymose inflorescence. 
    B. Simple raceme, spadix, spike, and catkin belong to racemose inflorescence.
    C. Cyathium, verticillaster, and hypanthodium belong to cymose inflorescence. Catkin belongs to racemose inflorescence. 
    D. Capitulum, globose head and catkin belong to racemose inflorescence. Verticillaster belongs to cymose inflorescence. 

    So, the correct answer is 'Simple raceme, spadix, spike, catkin'.
  • Question 3
    1 / -0
    Raceme inflorescence occurs in ________
    Solution
    In a raceme a flower develops at the upper angle (axil) between the stem and branch of each leaf along a long, unbranched axis. Each flower is borne on a short stalk, called a pedicel. An example of a raceme is found in the snapdragon (Antirrhinum majus).
    Raceme infloresence occurs in Delonix.
  • Question 4
    1 / -0
    Whorl of small green structures present around the sunflower is?
    Solution
    Capitulum or head bears many sessile and small florets. Main axis becomes flat and called receptacle. Peripheral florets called ray florets are pistillate or neuter and zygomorphic, whereas disc florets are bisexual and actinomorphic. At the base of flowers, a cluster of bracts forms an involucre (a whorl or rosette of bracts surrounding an inflorescence (especially a capitulum) or at the base of an umbel). Example: sunflower.

    So, the correct answer is 'Involucre'.
  • Question 5
    1 / -0
    Spadix inflorescence is characteristic feature of?
    Solution
    The spadix is a spike with a fleshy axis and having both male and female flowers. It is surrounded by large colored bracts called spathe. It is a type of racemose inflorescence. Examples:musa, palm, banana colocasia and alocasia.

    So, the correct answer is 'All of the above'.
  • Question 6
    1 / -0
    Which is nearest to corymb?
    Solution
    • Corymb: a flower cluster whose lower stalks are proportionally longer so that the flowers form a flat or slightly convex head.
    • Umbel: a flower cluster in which stalks of nearly equal length spring from a common center and form a flat or curved surface, characteristic of the parsley family.

    So, the correct answer is 'Umbel'.
  • Question 7
    1 / -0
    Capitulum inflorescence does not occur in?
    Solution
    Capitulum or head bears many sessile and small florets. The main axis becomes flat and called receptacle. Peripheral florets called ray florets are pistillate or neuter and zygomorphic whereas disc florets are bisexual and actinomorphic. It is a type of racemose inflorescence. Examples are dahlia, sunflower, marigold, and Asteraceae family. In China rose, a solitary flower is seen.

    So, the correct answer is 'China-Rose'.
  • Question 8
    1 / -0
    Characteristic bracts associated with spikelet inflorescence of grasses are?
    Solution
    A. Umbel in which the main axis is reduced very much and all flowers appear to be arising from the same point. At the base of flowers, a cluster of bracts forms an involucre. It is a type of racemose inflorescence. The example is hydrocotyle.
    B. Spikelet is a small and special. Flowers are produced in the axil of fertile bracts called lemma. Glume is a bract surrounding spikelet. It is a type of racemose inflorescence. Examples are wheat and grasses.
    C. Capitulum or head bears many sessile and small florets. The main axis becomes flat and called receptacle. It is a type of racemose inflorescence. 
    D. The spadix is a spike with a fleshy axis and having both male and female flowers. It is surrounded by large colored bracts called spathe. It is a type of racemose inflorescence.

    So, the correct answer is 'Glumes'.
  • Question 9
    1 / -0
    Which is not a correct match?
    Solution
    A. Catkin is a pendulous spike in leaf axis which bears unisexual flowers.  It is a type of racemose inflorescence. The example is mulberry.
    B. Capitulum or head bears many sessile and small florets. The main axis becomes flat and called receptacle.  It is a type of racemose inflorescence. The example is the sunflower.
    C. Corymb in which the main axis is short and lower flowers have long pedicels than upper ones so that all the flowers are brought more or less to the same level. It is a type of racemose inflorescence. The example is candytuft.
    D. Raceme in which peduncle has bisexual and pedicellate flowers arranged acropetally.  It is a type of racemose inflorescence. The example is a radish. Wheat is an example of the spikelet in which small and special spike and type of racemose inflorescence.
