The wordprokaryote comes from the Greek πρό (pro) "before" and κάρυον (karyon) "nut or kernel". Prokaryotes can be divided into two domains, archaea and bacteria.]]> 2017-06-21 13:30:03 UTC https://padlet.com/vmvalck/2g5gve2c4263/wish/177100178 vmvalck https://padlet.com/vmvalck/2g5gve2c4263/wish/177100224 All animals and plants are made of cells. Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant cells also have a cell wall, and often have chloroplasts and a permanent vacuole.]]> 2017-06-21 13:30:35 UTC https://padlet.com/vmvalck/2g5gve2c4263/wish/177100224 vmvalck https://padlet.com/vmvalck/2g5gve2c4263/wish/177100250 Animal cells are eukaryotic cells, or cells with a membrane-bound nucleus. Unlike prokaryotic cells, DNA in animal cells is housed within the nucleus. In addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. Organelles have a wide range of responsibilities that include everything from producing hormones and enzymes to providing energy for animal cells.]]> 2017-06-21 13:30:50 UTC https://padlet.com/vmvalck/2g5gve2c4263/wish/177100250
