Study Notes
Seed Definition
- Seeds are mature fertilized ovules containing an embryo; these are responsible for forming new plants upon germination.
Seed Transport
- Seeds are transported by animals, wind, and water.
Seed Germination
- When favorable conditions exist, water and oxygen penetrate the seed coat and the embryo grows.
Macroscopical Seed Characteristics
- Shape: Elongated, ovate, flattened, rounded base, pointed apex.
- Color: Dark brown.
- Odour: Odourless when whole, oily when crushed.
- Taste: Mucilaginous, oily.
- Surface: Finely pitted, smooth, shiny testa (seed coat).
- Type of Ovule: Anatropous ovule (Raphe extended half the seed circumference as a yellow shiny line).
Seed Transverse Section
- Testa: Outer and inner integuments.
- Outer integument: Forms the epidermis and hypodermis.
- Inner integument: Forms the scleride layer, hyaline layer, and pigment layer.
- Endosperm: Contains nutrients for the developing embryo.
- Embryo: Young plant inside the seed containing radicle (root), plumule (shoot), and cotyledons (seed leaves).
Cross Layer in Seed
- Contains fragments of elongated, lignified sclerenchymatous cells.
- These cells are crossed by thin-walled elongated cells on one side and rounded, thick-walled cells on the other side.
Medicinal Uses of Linseed
- Constipation: Increases bowel movements.
- Type 2 Diabetes: Slightly improves blood sugar control.
