Excretion - The removal from organisms of toxic materials, the waste products of metabolism and the substances in excess of requirements. DO NOT GET CONFUSED WITH EGESTION. THAT IS POO.
What is the description of Nutrition?
Nutrition - The taking in of materials for energy, growth and development . All organisms, including plants and bacteria require nutrients for their survival. Humans consume nutrients through eating whereas animals consume nutrients through diffusion and osmosis.
What are the 5 main classification kingdoms?
Animals- multicellular, do have a nucleus, reproduce sexually
Plants- multicellular, do have a nucleus, reproduce asexually, photosynthesise.
Fungi- Uni or multicellular, do have a nucleus, feed of others.
Prokaryotes- Unicellular, don’t have a nucleus, has a cell wall.
Protoctists- Unicellular, do have a nucleus, reproduce sexually and asexually, photosynthesise.
