Just read it. Okay?

1. SEEDS

2. A seed is the ripened ovule which consists
of the following parts:
1. testa – the seed coat or outer covering which is
partly impervious to water
2. endosperm – the nutritive tissue within the seeds
that stores food (if it is absent the cotyledon stores
the food)
3. embryo – the baby plant within the seed, it is
made up of cotyledon, epicotyl and hypocotyl

3. 4. Cotyledon – primary leaf of the embryo
5. Epicotyl – the part of the embryo that gives rise
to a shoot
6. Radicle – the primary root developing in a seed
7. Hypocotyl – the part of the embryo that is made
up of meristematic cells

5. Seed Dispersal – the spread or dissemination of
fruits and seeds to distant places. There are
several agents that help in this process
1. Wind
a. Wings – appendages which thin, flat and
membranous
ex: malunggay, samara
b. Hairs – either in one or two tufts or all
over the body
ex: talahib, cotton, amorseco, milkweed
c. Papery seeds – very light and paper-like

8. 2. Animals
hooks, barbs, spines, stiff hairs, sticky glands
birds are very effective
3. Water
air spaces, corky floats
