Fungi
Algae
Bacteria
Plants.
The correct answer is bacteria
Explanation:
This is because there are some bacteria that can convert atmospheric nitrogen into ammonia or nitrates which is absorbed by plants and stored in plants as source of protein, DNA for other organisms after consumption. Some bacteria reside in the root nodules of leguminous plants that convert atmospheric nitrogen to ammonia or nitrates. They are called nitrogen fixing bacteria which include nitrosomonas, Azotobacter. Nitryfing bacteria convert ammonia to nitrites or nitrates.
Mitosis is a type of cell division in which a parent cell divides to form two daughter cells with diploid number of chromosomes. The process takes place in the somatic cells (body cells) and in five steps namely; interphase, prophase, metaphase, anaphase and telophase. In telophase (the last stage of mitosis) the mitotic spindle breaks down and chromatin uncoils. This is essentially the opposite of what happens in prophase. In prophase chromatin condenses into discrete chromosomes visible with alight microscope and the mitotic spindle begins to form.
A dorsiventral (Lat. dorsum, "the back", venter, "the belly") organ is one that, like an ordinary leaf, has two surfaces that differ in appearance and structure from each other. As a synonym for dorsoventral organs, those reaching from the dorsal to the ventral surface, this term has also been used.
