EstherMtz2 https://padlet.com/EstherMtz2/4ibuh9jomsyu/wish/206087570 A cell is the basic unit of life that every living organism has or is made up of.]]> 2017-11-13 03:52:29 UTC https://padlet.com/EstherMtz2/4ibuh9jomsyu/wish/206087570 What is the difference between eukaryote and prokaryote? EstherMtz2 https://padlet.com/EstherMtz2/4ibuh9jomsyu/wish/206087666 A eukaryotic cell is a cell that has membrane bound organelles and a nucleus. These are usually the plant and animal cells. A prokaryotic cell is commonly found in bacteria. Prokaryotes have no nucleus nor membrane bound organelles. They usually have cilia and flagella's to move around.

EstherMtz2 https://padlet.com/EstherMtz2/4ibuh9jomsyu/wish/206087840 Both plant and animal cells are very different, but very similar as well. Plant cells are only found within plants and have organelles that animal cells do not have such as, chloroplasts, cell walls, and one central large vacuole. On the other hand, an animal cell contains centrioles that plant cells do not have. Centrioles are organelles that help assist cell division as well as the formation of spindle fibers which help separate chromosomes during cell division (meiosis)

  • Cohesion:
    • This property allows water molecules to stick together just like how they stick together in drinking water.
  • Adhesion:
    • This property allows water molecules to attach and stick to other surfaces like plastic or glass..
  • Capillary Action:
    • This property allows water to get into the pores of a paper towel and move up, against gravity..
  • Polarity:
    • This property allows water to have positive and negative charges. This makes it able to attract to polar molecules and surfaces.
  • Surface Tension:
    • This property allows a water strider to walk on the top layer of water without falling in because of the tightness on the top layer of water due to cohesion.
