They can range in size from just a few inches tall to more than 12 feet in the case of the tree ferns. Some types of ferns are tropical. Others quite hardy. Their versatility aside, ferns are valuable in the home and garden because they prefer shade. In the landscape, ferns bring fresh green life to those hard-to-design dim corners.
Prokaryotic cells have various shapes; the four basic shapes are: Cocci - spherical Bacilli - rod shaped Spirochaete - spiral shaped Vibrio - comma shaped.
Prokaryotes are primitive cells, without a nucleus or membrane bound organelles, has DNA located in a nuclear area, but the DNA is not bound inside the nucleus as in Eukaryotes. Prokaryotes have ribosomes, although the ribosomes are slightly more primitive than Eukaryotic cells.illions of years after the development of archaea and bacteria, the ancestors of todayâs eukaryotes split off from the archaea. So although archaea physically resemble bacteria, they are actually more closely related to us! In a eukaryote, the DNA is located in the nucleus of the cell.
