Morphology of Flowering Plants

Q1.In a racemose inflorescence, the youngest flowers are at the top and the oldest at the base (acropetal succession). If a researcher removes the growing tip, what would you expect compared to a cymose inflorescence where the tip naturally becomes a flower?

• ARacemose would stop producing new flowers; cymose would be unaffected since its tip already became a flower
• BBoth would continue producing flowers normally
• CCymose would start growing indefinitely
• DRacemose would switch to basipetal order

Q2.In racemose inflorescence, the main axis:

• ATerminates in a flower
• BContinues to grow and flowers are borne laterally
• CBears only a single flower
• DDoes not bear any flowers

Q3.Drupes develop from which type of ovary?

• AMulticarpellary syncarpous inferior ovary
• BMonocarpellary superior ovary
• CBicarpellary inferior ovary
• DPentacarpellary superior ovary

Q4.Epipetalous stamens are those which are attached to:

• AThe sepals
• BThe petals
• CThe ovary
• DThe receptacle

Q5.A botanist examines a plant and finds single leaves at each node on one side, then the other, in alternating fashion. Another plant has whorls of four leaves per node. Which phyllotaxy types are these, and which plant is an example of the second?

• AAlternate and whorled; Alstonia
• BOpposite and alternate; China rose
• CWhorled and opposite; Calotropis
• DAlternate and opposite; Guava
