In botany, a hilum (pronounced /ˈhaɪləm/) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). On a bean seed, the hilum is called the "eye".

The Hilum of a Seed
The hilum is a scar found on the seed of a plant. It is the point where the seed was attached to the fruit or ovary wall. This scar is formed during the process of seed maturation and is an important feature of a seed. It provides a connection between the seed and the parent plant, allowing the transfer of nutrients and water.
Function of the Hilum
The hilum has several important functions in a seed:
1. Attachment Point: The hilum serves as the attachment point for various structures during seed development. These structures include the funicle, micropyle, and chalaza.
2. Nutrient Transfer: The hilum is responsible for the transfer of nutrients from the parent plant to the developing seed. It is through this scar that nutrients, such as sugars and minerals, are transported to the seed to support its growth and development.
3. Water Uptake: The hilum also plays a role in water uptake by the seed. It allows water to enter the seed through the micropyle, which is a small opening located near the hilum. Water absorption is crucial for seed germination and the initiation of plant growth.
The Role of the Funicle
The funicle is a structure that connects the seed to the ovary wall. It is an elongated stalk-like structure that is attached to the hilum. The funicle is responsible for transporting nutrients and water from the parent plant to the developing seed.
Connection between the Hilum and Funicle
The hilum and funicle are closely related as the hilum is the scar left behind when the funicle detaches from the seed. The funicle serves as the connection between the seed and the parent plant, while the hilum is the mark left behind after the detachment.
Therefore, the correct answer to the given question is option 'B' - The hilum is a scar on the seed, where the funicle was attached.
