Basically the seed contains 2 parts, the testa, which is the seed coat that protects the seed and cotelydon, which is the inside of the seed, containing the radical and plumle.
for seed to germinate, we need 3 basic conditions,
warmth, it is the suitable temperature for seed germination, it can influence the activity of enzymes. providing a optimum temperature
water, to soften down the testa so that the shoot can break out from the testa
and oxygen, for aerobic respiration
.
If these conditions are absent, the seed may be in the state of dormancy. where is won't germinate until it meets the suitable conduction.
after that, the enzyme will digest the nutrient inside the seed and provide amino acid, which is necessary to seed germination. and meanwhile the aerobic respiration provides energy, so that the plumlecan shoot out, and be the shoot of the plant.
and then until it grows leaves, it'll start to complete photosynthesis, instead of using the nutrients inside the cotelydon.
It would most likely die because it needs nitrogen , sunlight , and water , basic things that you can't exactly find in space....
Answer:
It depends on the graphics you have but:
Explanation:
The theory of one colonization and then radiation should see as only one group on your phylogeny, all branches come from a single point.
Now, convergent evolution means that in different islands the same morphologic pattern is seen BUT not come from the same ancestor. This means that the morphologic pattern was built under the island conditions and NOT as colonization from another island
If there is one colonization and then radiation all islands have to have their own phylogeny and same morphs on each phylogeny to be convergent.
It depends on which forms they come in.
Answer:
b-las hojas
Explanation:
Fotosíntesis: Se realiza en las hojas que se orientan hacia la luz. La clorofila atrapa la luz del sol.
