Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte
Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)
Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition
Mitosis-both (mitosis occurres in spores)
Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
Im almost certain the answer is D but theres a chance I might be wrong
Answer:
The correct answer is b. I and II
Explanation:
Sexual reproduction is present in higher forms of life and absent in prokaryotes like bacteria. Sexual reproduction results in greater evolutionary changes due to the fusion of two different gametes from two different individuals of a species.
Therefore sexual reproduction helps in increased genetic diversity in higher forms of life. In prokaryotes like bacteria, genetic diversity is maintained and increased through DNA transfer from one bacterial cell to another with the help of a process known as horizontal gene transfer.
Bacteria have sex pilli which is used to introduce the genes to the other bacteria. By this process, they increase their genetic diversity and evolve continuously. So the correct is b. I and II.
<h2>Answer:</h2>
It is a true statement.
Explanation:
The plan cell wall is composed of 3 layers or 3 types of walls:
- Primary cell wall.
- Secondary cell wall.
- Middle lamella.
Between primary and secondary there is middle lamella.
These layer make it a laminated two layer structure.
