SEEDS Flashcards
The structure that develops from the ovule after fertilization
Seeds
Parts of the Seed
Seed Coats
Endosperm
Embryo
The covering of the Seed
Made up of the testa derived from the outer integument and the tegmen from the inner integument
Seed Coats
Associated with the seed coat are:
Hilum
Micropyle
Raphe
Scar on the Seed Coat
Hilum
Small Opening near the Hilum
Micropyle
Ridge located on the Testa
Raphe
Derives from the primary endosperm cell and contains the stored food of the seed
Endosperm
This is the young plant inside the seed with the following parts: Cotyledon, Epicotyl, and Hypocotyl
Embryo
Embryo is the young plant inside the seed with the following parts:
Cotyledon
Epicotyl
Hypocotyl
One or two seeded leaves
Cotyledon
Part of the embryo above the point of attachment of the cotyledons; its growing tip, the plumule, constitutes the first bud
Epicotyl
Part of the embryo below the point of attachment of the cotyledons; its growing tip, the radicle give rise to the primary root
Hypocotyl
Types of Seed based on the location of the stored food
Endospermic Seeds(Albuminous Seeds)
Non-endospermic Seeds(Exalbuminous Seeds)
Endosperm is present for food storage
Endospermic/Albuminous Seeds
