Arisha's cells movie

  1. 1. Welcome to see presentation on cells
  2. 5. Eukaryotic cell A  eukaryote  (pronounced  /juːˈkæriɒt/  or  /juːˈkærioʊt/ ) is an  organism  whose  cells  contain complex structures inside the  membranes . The defining membrane-bound structure that sets eukaryotic cells apart from  prokaryotic  cells is the  nucleus , or  nuclear envelope , within which the genetic material is carried. [1] [2] [3]  The presence of a nucleus gives eukaryotes their name, which comes from the  Greek   ευ  (eu, "good", "noble" & "true") and  κάρυον  (karyon, "nut" & "kernel"). Most eukaryotic cells also contain other membrane-bound  organelles  such as  mitochondria , chloroplasts  and the  Golgi apparatus . Almost all  species  of large organisms are eukaryotes, including  animals ,  plants  and  fungi , although most species of eukaryotic  protists  are microorganisms .
  3. 6. Prokaryotic cell The prokaryotes are divided into two domains: the  bacteria  and the  archaea . Archaea were recognized as a  domain of life  in 1990. These organisms were originally thought to live only in inhospitable conditions such as extremes of  temperature ,  pH , and radiation  but have since been found in all types of  habitats .
  4. 10. DNA
  5. 11. Deoxyribonucleic acid (DNA) is a  nucleic acid  that contains the  genetic  instructions used in the development and functioning of all known living  organisms  and some  viruses . The main role of DNA molecules  is the long-term storage of  information . DNA is often compared to a set of  blueprints  or a recipe, or a  code , since it contains the instructions needed to construct other components of  cells , such as proteins  and  RNA  molecules. The DNA segments that carry this genetic information are called  genes , but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.
