With that said, letâs make a potato battery â¦ Objective. We only need a potato, a couple nails and a piece of wire to make a potato battery. Itâs a fun science project that helps show the way things work in a battery by using everyday items we see around the house. As in the lemon battery the goal is to learn more about electricity, and possibly a few new science terms along the way.
5. Plantae -- multicellular, eucaryotic, rigid cell walls, nutrition by photosynthesis (make their own nutrients converting solar energy into chemical energy in the bonds of sugar molecules; autotrophic).Plants are a major food source for many other organisms.. Fungi - - multicellular, eucaryotic organisms, nutrition by absorption (heterotrophic), cell walls made of chitin digest externally and absorb nutrients, Also play a major role in global recycling.
Within plant cells are chloroplasts (KLAWR-uh-PLASTS), organelles in which the energy from sunlight is used to make sugar. Plants use some of the sugar immediately, to keep their cells functioning. The rest of the sugar is stored in the cells. Animal cells do not contain chloroplasts.As a result, animals are not able to use the energy of the Sun directly. Instead, animals get their energy from food. Much of the food an animal uses for energy comes from the sugar that plant cells have stored.ithin plant cells are chloroplasts (KLAWR-uh-PLASTS), organelles in which the energy from sunlight is used to make sugar.
