The seed of a teakwood tree (Tectona grandis) is a small, brown, oval-shaped structure, typically about 1 centimeter in length. Inside the seed, there is an embryo, which is the early stage of a plant's development that will eventually grow into a mature tree. The seed also contains endosperm, a nutrient-rich tissue that provides nourishment to the developing embryo. Teakwood tree seeds are known for their high oil content, which helps protect the embryo from drying out and provides energy for germination.
Inside a teakwood tree seed, you would find several components crucial for its growth and development:

Seed Coat: The outer covering of the seed, protecting the inner contents from damage and dehydration.

Embryo: The embryo is the young, undeveloped plant inside the seed. It consists of the embryonic axis (the future stem and root) and one or two cotyledons (seed leaves) that contain stored food reserves.

Endosperm: This is a tissue rich in starch and other nutrients that surrounds the embryo and provides nourishment for its initial growth until it can establish roots and begin photosynthesis.

Storage Reserves: Teakwood tree seeds contain stored nutrients, primarily in the form of oils and carbohydrates, which the embryo uses during germination until it can produce its own food through photosynthesis.

Radicle: This is the embryonic root of the plant, which emerges first during germination and develops into the primary root system of the mature tree.
