The modern seed plant phyla of ginkgos, cycads, conifers, and gnetophytes are collectively known as gymnosperms.
Phylum is a taxonomic rank below state and above magnificence in the organic class, particularly of animals. In plant life, the corresponding rank is department. instance: Phylum Chordata consists of magnificence Mammalia (mammals), magnificence Aves (birds), magnificence Ascidiacea (sea squirts), and so forth.
At its maximum simplicity, a phylum may be described in ways: as a collection of organisms with a positive degree of morphological or developmental similarity (the phenetic definition), or a collection of organisms with a certain diploma of evolutionary relatedness (the phylogenetic definition).
The phrase become later modified to phylum. There are approximately 35 animal phyla, 12 plant phyla, and seven phyla of fungi. The microorganism, including the archaea, are grouped into roughly 34 phyla, despite the fact that the relationships between these organizations aren't as nicely hooked up.

Option A, When cells undergo meiosis, the cells of sexual reproduction are divided into two parts, the first is the meiotic division that is reductional division, and the second is an equational division because they have the same number of chromosomes of the stem cell And in this situation, there is no duplication of DNA.
Answer:
The suitable option will be - B
Citric acid cycle
Explanation:
The results were -
Glucose: None
CO2: Increase
O2: None
ATP: Increase
NADH: Increase
- We know that the Citric acid cycle is also known as the TCA cycle (tricarboxylic acid cycle) or the Krebs cycle. This cycle occurs in Mitochondria in case of eukaryotes. In this cycle acetyl-CoA is oxidized which comes from carbohydrates, proteins and fats and energy is released in the form of ATP.
- water is also used in this process. NAD+ gets reduced to NADPH. In this system carbon dioxide is produced as a waste byproduct. ATP is produced as the main product. ATP is also used as a source of energy.
Annelids have neither an external or an internal shell. Examples of annelids are
earthworms and leeches.
