Question

Phyllotaxy is the pattern of arrangement of ____________.

• A. sepals
• B. leaves
• C. flowers
• D. fruits

Hint:

Use simple linguistic associations to recall plant morphology definitions instantly: \[ \text{\textbf{Phyllo}-taxy} \rightarrow \text{\textit{Phyllon} = \textbf{Leaf}} \quad \Longrightarrow \quad \text{Arrangement of Leaves} \] \[ \text{In-\textbf{flores}-cence} \rightarrow \text{\textit{Flos} = \textbf{Flower}} \quad \Longrightarrow \quad \text{Arrangement of Flowers} \]

Answer 1

The Correct Option is B

Step 1: Break down the word.
Phyllotaxy comes from phyllo meaning leaf and taxis meaning arrangement.
Step 2: State the definition.
So phyllotaxy is the pattern of arrangement of leaves on the stem or branch.
Step 3: List the leaf patterns.
Leaves may be alternate, opposite, or whorled, which are the three main types of phyllotaxy.
Step 4: Check the term for sepals.
The arrangement of sepals or petals in a bud is called aestivation, not phyllotaxy, so sepals is wrong.
Step 5: Check the term for flowers.
The arrangement of flowers on the floral axis is called inflorescence, so flowers is wrong.
Step 6: Conclude.
Since the word strictly means leaf arrangement, the correct option is leaves.
\[ \boxed{\text{leaves}} \]
