During meiosis I, homologous chromosomes line up side by side and may shuffle genetic material between themselves.
<h3>What is Meiosis?</h3>
- In sexually reproducing organisms, meiosis is a unique type of cell division of germ cells that results in the production of gametes, such as sperm or egg cells.
- Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome.
- Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.
- It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
- By halving the same, it keeps the chromosomal count constant.
<h3>What is chromosome?</h3>
- A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code.
- Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.

<span>Deuteromycota are the imperfect fungi. Sexual reproduction has never been observed in them. Penicillium does not seem to have an actual sexual phase, and therefore, it is calssified under Deteromycota. It is multicellular and have erect hyphae, which possess the asexual conidiophores</span>
Stem cells can give rise to specialized cells. When unspecialized stem cells give rise to specialized cells, the process is called differentiation. While differentiating, the cell usually goes through several stages, becoming more specialized at each step. Scientists are just beginning to understand the signals inside and outside cells that trigger each step of the differentiation process.

Answer:
Bacteria has prokaryotic cells i. e. no true nucleus or membrane around the nucleus. They lack mitochondria, ribosome, lysosomes, endoplasmic reticulum, golgi bodies and cell wall.
Explanation:
Prokaryotes are the organisms which have no true nucleus while eukaryotes have true nucleus. True nucleus means that the membrane is present around the nucleus. Many organelles are also absent in prokaryotic cell which are present in eukaryotic cells.
