Flashcards
Seed Coat
Seed Coat
The outer protective layer of a seed, which helps to protect the embryo and endosperm from damage and drying out.
Embryo
Embryo
The young plant that develops from a fertilized egg, containing the future roots, stem, and leaves.
Endosperm
Endosperm
The nutritive tissue in a seed that provides food for the developing embryo.

Study Notes
Seed Structure
- A seed typically consists of a seed coat, an embryo, and an endosperm.
- The seed coat provides protection for the developing embryo and endosperm.
- The embryo is the rudimentary plant that will develop into a new seedling.
- The endosperm is a nutritive tissue that provides nourishment to the developing embryo.
- The three-part structure is a common characteristic of many seed plants contributing to their evolutionary success.
- Seed coat often comprises multiple layers; variations in structure and composition between species.
- The embryo, containing the rudimentary shoot and root, plays a pivotal role in germination.
- The endosperm stores nutrients which facilitate embryonic growth prior to photosynthesis.
- In some seeds, the endosperm is fully utilized by the embryo before germination, while in others, it remains substantial.
