Plant Life
Cycle
Rima : Assalamu’alaikum
warahmatullahi wabarakatuh. Alhamdulillahi robbil allamin, wabihi nasta’inu ala
umuri dunya wadin, wa sholatu wa salamu ala asrofil anbia’i walmursali, wa’ala
alihi wa sohbihi aj’main, ama ba’du.
All thanks and grateful we give to Illahi robbi,
who has bless us so we can gather here now. Shalawat and salam hopefully always
we give to our lord Habibbana wanabiana Muhammad SAW, to his family and his
best friends, also us as his people who isya Allah obey his rules.
In this
opportunity, we from group 3 will explain about plant life cycle. I’m Rima as
the moderator and they are Isna, Ana, and Angela as the explainer. First
explanation will be explained by Isna.
Isna : I
will explain to all of you about how a plant grows. A plant’s life cycle starts
from a seed. When a seed gets enough water and the conditions is just right, there
will grow a small root downwards. After some time, the stem will grow upward
and become a sprout. The sprout will grow like the plant where it came from.
From the stem, there will grow leaves and flowers that will form more seeds. The
life cycle of the plant will begin again.
Now you have known about how a plant grows. Next
explanation will be explained by Ana.
Ana : Now
I will explain about how a plant can make a new seed. To make a new seed, one
or more plants need female gametophyte and male gametophyte. Plants get female
gametophyte from pistil. Inside it, there’s an ovule that has megaspore. Then it
will become an egg. Male gametophyte obtained from the anther. It will perform
meiosis and become microspores. The microspores also become pollen. Then, the
egg from pistil will meet the pollen. They will fertilize and become a zygote.
The zygote will grow up and become a new seed. Inside it, there’s an embryo.
Do you want to know the detail of the process?
Let Angela explain that part to you.
Angela : Last
explanation is about the detail of how the female gametophyte meets the male
gametophyte. Female gametophyte or egg is waiting pollen on the ovary. Pollen
can get there by the help of wind or insects like bees. Then the pollen
germinated and goes to the pollen tube toward the ovary. After that, the pollen
meets the egg and the nuclear fusion within embryo sac. There will be formed
zygote from two nuclei and endosperm nucleus that has three nuclei. The
endosperm itself contains some nutrition and minerals that the embryo needs
while it isn’t unite again with the main plant.
That’s all that I can explain to you.
*** QUESTION AND ASK SESSION ***
Rima : That’s
all that we can deliver to all of you. We’re apologizing if there’s any mistake.
Hopefully our group’s explanation about Plant Life Cycle can increase your
insight. Thank you for your attention.
