Inflorescence - racemose and cymose MCQs with solutions
10 of the 13 published questions on this topic, exactly as they appear in a test. Answers and worked solutions come with your result rather than on this page.
In a racemose inflorescence, what happens to the main axis?
- A. It continues to grow
- B. It terminates in a flower early
- C. It becomes an underground stem
- D. It produces only one flower
Which flowering sequence is typical of a racemose inflorescence?
- A. Older flowers toward the base and younger flowers toward the apex
- B. Younger flowers toward the base and older flowers toward the apex
- C. All flowers develop simultaneously
- D. Only the terminal flower develops
Why is a cymose inflorescence described as determinate?
- A. The main axis ends in a flower and therefore has limited growth
- B. It never produces lateral flowers
- C. Its flowers lack pedicels
- D. The main axis grows indefinitely
In a racemose inflorescence, the main axis generally
- A. continues to grow and bears flowers laterally
- B. ends in a terminal flower early
- C. produces only one flower
- D. never elongates or branches
In racemose inflorescence, .
- A. The main axis terminates in a flower
- B. Flowers are solitary
- C. The growth is limited
- D. Flowers are borne in an acropetal succession
Match the following : Type of flower Example (A) Zygomorphic (I) Mustard (B) Hypogynous (II) Plum (C) Perigynous (III) Cassia (D) Epigynous (IV) Cucumber Select the correct option :
- A. (A)-(I), (B)-(II), (C)-(IV), (D)-(III)
- B. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
- C. (A)-(IV), (B)-(I), (C)-(III), (D)-(II)
- D. (A)-(III), (B)-(I), (C)-(II), (D)-(IV)
Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R : Assertion A : A flower is defined as modified shoot wherein the shoot apical meristem changes to floral meristem. Reason R : Internode of the shoot gets condensed to produce different floral appendages laterally at successive node instead of leaves. In the light of the above statements, choose the correct answer from the options given below :
- A. Both A and R are true but R is NOT the correct explanation of A
- B. A is true but R is false
- C. A is false but R is true
- D. Both A and R are true and R is the correct explanation of A
Ray florets have
- A. Superior ovary
- B. Hypogynous ovary
- C. Half inferior ovary
- D. Inferior ovary
An inflorescence has a terminal flower that opens first, while progressively younger flowers occur toward the base. Which type is indicated?
- A. Cymose
- B. Racemose
- C. Solitary axillary
- D. Spadix only
Inflorescence X has an indefinitely growing main axis with acropetal flower succession. Inflorescence Y terminates in a flower and shows basipetal succession. Which pairing is correct?
- A. X racemose, Y cymose
- B. X cymose, Y racemose
- C. Both racemose
- D. Both cymose
Common mistakes in Inflorescence - racemose and cymose
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Reverses acropetal and basipetal succession.
- Calls the pattern racemose despite the terminal flower ending main-axis growth.
- Uses only flower number and ignores axis growth and sequence of maturation.
