Answer

To answer the question "Remnant endosperm" is commonly found in the seed of which family, we can follow these steps:

### Step 1: Understand the Concept of Endosperm
- The endosperm is a tissue that provides nourishment to the developing embryo in seeds. It is formed as a result of a process called triple fusion during double fertilization in flowering plants.

### Step 2: Identify the Nature of Remnant Endosperm
- After the embryo develops, some seeds retain a small amount of endosperm, known as remnant endosperm. This remnant serves as additional nourishment for the seedling after germination.

### Step 3: Determine Which Plant Families Exhibit Remnant Endosperm
- It is important to know which plant families commonly have seeds with remnant endosperm. The video mentions that this is particularly common in the family Arecaceae (palmyra or palm family).

### Step 4: Provide Examples
- The video gives examples of plants within the Arecaceae family that exhibit remnant endosperm, such as Erikanat and Passiflora.

### Step 5: Conclude with the Correct Answer
- Based on the information provided, the correct answer to the question is that remnant endosperm is commonly found in seeds of the Arecaceae family.

### Final Answer:
Remnant endosperm is commonly found in seeds of the Arecaceae family.
