Answer:

Green algae is divided into chlorophyte and chlorophyte. It possess chlorophyll a and b.

Bryophytes includes the liverworts, mosses and hornworts. It is know tracheaophytes I.e. is not vascular without extensive transport system, it needs water to reproduce sexually. It's Gametophyte is dominant and stomata are absent. (Hornworts possess stomata; it's related to tracheaophytes.

Ferns have vascular tissue, xylem and pholem, stem, root, leaves, dominant sporophyte. It's sporophyte possess rhizomes and fronds plus sporingia aldo called sori. Ferns are seedless vascular plants.

Gymnosperms includes the conifers, cycad e.t.c. It has its ovules resting on a scale. The ovules later develop into the seed. These seeds are naked as there are not enclosed in the chambers.

Angiosperms have flowers and fruits and show diuble fertilization. This is a  huge clade that consists of all flowering plants. Unlike Gymnosperms

lozanna [386]

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.
