Melissa - Cells, Living & Non-Living things

This term in Science we are learning about Living & Non-living things and Cells. The way cells function, the way they're structured & how they move, where they're located, all of that stuff.

In the cell system of a human, altogether there are 6 cell organelles. A Cell membrane, Cell wall, Nucleus, Cytoplasm, Mitochondria & Vacuole. The structure of most cells are shaped in a Bean form. With curvy outsides, floating around in the liquid of Cytoplasm within the Cell organelle. Cytoplasm is a watery jelly substance that contains chemicals and nutrients inside. The cell organelles are held together by the Cytoplasm which is one of the Cytoplasm's main functions. All cells function a different way and take have different strengths. They lay in all living things, because it takes a big role in keeping us alive.

Living things have 7 characteristics.

  • Movement, every living thing moves. We're either moving ourselves using our brain and mind signals or like plants, are being forced to move by the weather or someone playing around with it. 
  • Respiration, Respiration is burning food to obtain energy which we do when we eat.
  • Sensitivity, when we react to the things around us. Just like the 5 senses us humans have. 
  • Growth, 
  • Reproduction means to create things. Adults create babies & plants create food.
  • Excretion, is the process of waste removal from the body.
  • & Nutrition, When we obtain food in order to grow. 
 Non-Living things show one or two of these but do not show all.
