• Task 2: seed germination (polyembryonic) Citrus(siam) and
mango(arumanis)
1. Papaya seeds 2.
Tomato seeds 3.
Castor seeds 4. Red
bean seeds 5. Corn
seeds 6. Orchid seeds
• Today's task: look for it, tomorrow you have to plant it. Just use sand so
it's easy to see the roots. Then observed
cotyledons thicken and store reserve substances for young plant seeds.
Such seeds are called exalbuminous seeds. In other plants, such as Ricinus
and Gramineae, the endosperm tissue is still present when the seed
germinates. Seeds that have food reserves in the form of endosperm or
perisperm are called albuminous seeds .
That integument will become the seed coat. Seen in corn kernels. Actually,
corn is a kareopsis fruit. Because the pericarp or skin of the fruit is thin and
attached to the seed coat. Seeds (albuminous) generally consist of seed
coat, embryo, endosperm. Seeds (albuminous) are seeds which when ripe
have food reserves in the form of endosperm or perisperm. In red beans
there are cotyledons and
Seed: a zygote is a means of sexual reproduction. If vegetative is reproduction
without fertilization. Seeds develop from fertilized ovules (ovules). Inside the
ovule there is an embryo sac with an ovum which, if it has been fertilized,
will develop an embryo. So the fertilized ovum becomes a zygote, the zygote
becomes an embryo. then the other is the polar body or biological nucleus
of the secondary institution which is fertilized by sperm to become the
endosperm. Endosperm is the storage tissue in seeds that provides food for
embryos and young plant seeds. In certain plants, for example Pisum,
Phaseolus, Glycine and Arachis, the entire endosperm tissue is digested by
the developing embryo. In general, in the seeds of such plants,
The ovum is a structure consisting of integument and covering the nucellus
and the embryo sac which is connected to the mother through the funiculus
(talipusar) which is attached to the placenta.
next 3 weeks
• Task 3 : Corn & red bean sprouts
If the nucellus which has an embryo sac after fertilization there is a nucellus
which is still there, it is completely lost because it feeds for the development
of the embryo sac. If so, the part of the embryo sac or the one with the
nucellus will grow and develop attached to the integument.
• Soak overnight so it's easy to open the skin. • Plant
from now on corn & red beans • For germination: corn
and red beans • Plant 1 1 1 1 every day until day 14.
Remove the 14th day and then sort and construct.
