They are covered by a hardened seed coat called a testa.
They contain a diploid embryo or zygote.
They are nourished by a single (monocotyledonous) or double (dicoltyledonous) tissue; this/ these cotyledon(s) become the first primary leaves on germination.
Seeds are contained in the ovary (or fruit) until ripe (although there are few exceptions).
Seed can remain viable (for germination) from anywhere between 30 days and 100 years - there is a recent example of a 30,000 frozen seed (Siberia) being sucessfuly germinated (Feb 2012)

What are two characteristics of a seed help an embryo survive harsh conditions?
Inside a seed is a food supply for the developing plant embryo. The outside of a seed is a protective coat. This allows a seed to survive cold weather or a lack of water. A seed can remain dormant for months, or even years, while waiting for the right growing conditions.
What are the characteristics and significance of long seed pods on trees?
Long seed pods on trees are elongated structures that contain seeds. These pods are significant because they help in seed dispersal, allowing the tree to reproduce and spread its seeds over a wider area. Additionally, the length of the seed pods can vary depending on the tree species, with some trees having longer pods to aid in dispersal by wind or animals.
