Life Cycle Of Angiospermae Flashcards
How many lifecycles does phylum angiospermae have?
7
What is the first step in the life cycle of phylum angiospermae?
Microgametophytes (pollen grains) develop from microspores with athens
What is the second step in the life cycle of phylum angiospermae?
Megametophytes develop from megaspores with an ovule
In the second part of the angiospermae life cycle. How many antipodal cells it has?
3
In the second part of the angiospermae life cycle. How many synergids do they have?
2
What does the synergids do in the angiospermae life cycle?
It guards the micopyle (where the sperm tube enters the female gametophyte)
In the second step of the life cycle of angiospermae. What does the central cell has?
It has 2 polar nuclei fertilized to form endosperm
In the second step of the life cycle of angiospermae. How many egg cells does it have? And what does it do?
It has 1 egg cell and it is fertilized to form the zygote
What is the third step in the life cycle of phylum angiospermae?
The sperm from the pollen grain more in the sperm into the female gametophyte through micropyle
What is the fourth step in the life cycle of phylum angiospermae?
One sperm fertilizes the central cell to produce triploid endosperm
What is the five step in the life cycle of phylum angiospermae?
Another sperm fertilizes the egg nucleus to form the zygote
What is the sixth step in the life cycle of phylum angiospermae?
Female gametophyte which is found in an ovule will develop into a seed
What is the seventh step in the life cycle of phylum angiospermae?
The ovary will develop into a fruit
