The aleurone layer in maize grain is present in peripheral region of endosperm specially rich in

Options

A. lipids
B. auxins
C. proteins
D. starch

Answer

**Step-by-Step Solution:**

1. **Understanding the Aleurone Layer**: The aleurone layer is a single cell thick layer found in the endosperm of monocot seeds, such as maize (corn). It plays a crucial role in the utilization of stored nutrients for the growth of the embryo.

2. **Location of the Aleurone Layer**: In maize grain, the aleurone layer is located in the peripheral region of the endosperm. This means it is situated on the outer edge of the endosperm, surrounding the starchy part of the grain.

3. **Composition of the Aleurone Layer**: The aleurone layer is known to be rich in certain substances. Specifically, it contains proteinaceous aleurone grains. These grains are primarily composed of proteins, which are essential for the growth and development of the embryo.

4. **Conclusion**: Therefore, the aleurone layer in maize grain is especially rich in proteins. This is significant as these proteins provide the necessary nutrients for the germinating seed.

5. **Final Answer**: The aleurone layer in maize grain is present in the peripheral region of the endosperm and is especially rich in proteinaceous aleurone grains.
