In which of the following would you find retained endospermic tissue even after the formation of the seed ?

Options

A. Gram
B. groundnut
C. Castor
D. Bean

Answer

To solve the question, "In which of the following would you find retained endospermic tissue even after the formation of the seed?", we can follow these steps:

### Step 1: Understand the Types of Seeds
Seeds can be classified into two categories based on the presence of endosperm after the formation of the seed:
- **Endospermic seeds (Albuminous seeds)**: These seeds retain the endosperm even after the seed has formed.
- **Non-endospermic seeds (Exalbuminous seeds)**: These seeds do not retain endosperm as it is consumed during the formation of the embryo.

### Step 2: Identify Examples of Each Type
- **Endospermic seeds**: Examples include castor, coconut, and maize. These seeds have retained endosperm.
- **Non-endospermic seeds**: Examples include gram, groundnut, and beans. In these seeds, the endosperm is completely consumed during embryo development.

### Step 3: Analyze the Options
Now, we need to determine which option corresponds to the endospermic seeds. The question specifically asks for seeds that retain endospermic tissue after seed formation.

### Step 4: Select the Correct Answer
From the examples provided:
- Castor is an endospermic seed, meaning it retains endospermic tissue.
- Other examples like gram, groundnut, and beans are non-endospermic seeds, meaning they do not retain endosperm.

Thus, the correct answer to the question is **castor**.

### Final Answer
The retained endospermic tissue is found in **castor** seeds.
