Amphivasal vascular bundles are found in

Options

A. Cycas and Dryopteris
B. Dracaena and Yucca
C. Helianthus and Cucurbita
D. Maize and Wheat

Answer

To answer the question "Amphivasal vascular bundles are found in," we can follow these steps:

### Step 1: Understand the Definition of Amphivasal Vascular Bundles
Amphivasal vascular bundles are a type of vascular bundle where the phloem is located on the inside and is surrounded by xylem. This unique arrangement is different from the more common arrangement where xylem surrounds phloem.

**Hint:** Remember that in amphivasal bundles, phloem is surrounded by xylem, which is the defining characteristic of this type of vascular bundle.

### Step 2: Identify the Plants that Contain Amphivasal Vascular Bundles
From the information provided, we learn that amphivasal vascular bundles are specifically found in certain plants. The transcript mentions that these bundles are found in "drosina" and "eucalyptus."

**Hint:** Focus on the specific examples given in the transcript to identify the plants that exhibit amphivasal vascular bundles.

### Step 3: Conclude the Answer
Based on the information gathered, we can conclude that amphivasal vascular bundles are found in Drosina and Eucalyptus.

**Hint:** When answering questions about specific plant structures, always refer back to the examples provided in your study materials or transcripts.

### Final Answer
Amphivasal vascular bundles are found in Drosina and Eucalyptus.
