Question

Answer

The cotyledon of the maize grain is technically called the scutellum. The term comes from the Latin term scutum which means shield. The scutellum is thin with a high surface area that allows for the easy absorption of the nutrients from the endosperm as the seed grows. It is a modified cotyledon or seed leaf. In old maize seeds as the endosperm loses the ability to provide the needed nutrients to the embryo, the scutellum appears to give the needed nutrients for the growth of the embryo.
Hence, the correct answer is option 'C'.

Answer

Answer

Maize is a monocot and  cotyledon of monocot plants are called scutellum

Answer

The cotyledon of maize grain is technically called the scutellum. The scutellum is an important part of the seed that plays a crucial role in the germination and early growth of the plant. Let's delve into the details of the scutellum and its functions.

Scutellum - The Cotyledon of Maize Grain
The cotyledon is the primary embryonic leaf found in the seed of a flowering plant. In the case of maize grain, the cotyledon is known as the scutellum. The scutellum is located on one side of the embryo and is usually large and shield-shaped.

Functions of the Scutellum
1. Nutrient Absorption: The scutellum is responsible for absorbing nutrients from the endosperm, a tissue that surrounds the embryo. The endosperm is rich in starch and proteins, which serve as the main source of energy and nutrients for the developing plant. The scutellum takes up these nutrients and transports them to the growing embryo.

2. Enzyme Secretion: The scutellum secretes enzymes called amylases. Amylases break down the stored starch in the endosperm into simple sugars, such as glucose and maltose. These sugars are then transported to the growing embryo to provide energy for its development.

3. Absorption of Water: The scutellum also helps in the absorption of water from the surrounding environment. It absorbs water and transfers it to the embryo, ensuring proper hydration for germination and early growth.

4. Protection: The scutellum acts as a protective covering for the delicate embryo within the seed. It shields the embryo from mechanical damage and helps maintain its viability during unfavorable conditions.

Conclusion
In conclusion, the cotyledon of maize grain is called the scutellum. It plays a vital role in nutrient absorption, enzyme secretion, water absorption, and protection of the embryo. Understanding the functions of the scutellum is crucial to comprehend the germination and early growth processes of maize plants.
