Chromosomes have hereditary function that are capable of self-duplication and they have thread-like structures seen inside the nucleus of plant and animal. In plants, they go through a cycle called alteration of generation that has multicellular stages. One is sporophyte that is a diploid, and the other is gametophyte with a haploid.
Moreover, spores are produce through meiosis so it go through a process of chromosome reduction in order to create a haploid spores. While, gametes undergo mitosis and the structure is already a haploid, which means that the number of chromosomes will not change in order to produce haploid. In this case, the plant have both spores and gametes and the similarities is that, they are both singles celled and a haploid. Therefore, the number of the chromosome in the gametophyte generation is also 32.
Used by American pioneers living in the Great Plains in the 19th century. The emigrants traveled by wagon in search of fertile land in Oregon's Willamette Valley.
Answer:
The bulging eyes of most frogs allow them to see in front, to the sides, and partially behind them. The eyes help push the food down its throat. Eyes positioned atop the head give frogs a field of vision of almost 180 degrees. This peripheral vision helps them spot predators and prey.
