Kernel is
(a) Whole seed
(b) Seed without seed coats
(c) Embryo excluding endosperm
(d) Seed excluding covering and embryo

Options

A. Whole seed
B. Seed without seed coats
C. Embryo excluding endosperm
D. Seed excluding covering and embryo

Answer

To determine what a "kernel" is, let's analyze the options provided step by step:

1. **Understanding the Definition of Kernel**: The kernel is defined as the innermost edible part of a seed. It includes important structures that are vital for the seed's development.

2. **Evaluating Each Option**:
- **Option (a) Whole seed**: This option suggests that the kernel is the entire seed. Since the kernel includes all edible parts, this is a strong candidate.
- **Option (b) Seed without seed coats**: This option implies that the kernel excludes the seed coat. However, the kernel is typically considered to include the edible parts that are protected by the seed coat, making this option incorrect.
- **Option (c) Embryo excluding endosperm**: This option states that the kernel is just the embryo without the endosperm. However, the kernel usually includes both the embryo and the endosperm, so this option is also incorrect.
- **Option (d) Seed excluding covering and embryo**: This option suggests that the kernel excludes both the seed covering and the embryo, which contradicts the definition of a kernel as it should include the edible parts, making this option incorrect as well.

3. **Conclusion**: Based on the analysis, the most accurate definition of a kernel aligns with option (a) "Whole seed". Therefore, the correct answer is **(a) Whole seed**.
