Survival Words
Excretion is how multi-cellular organisms remove waste.
Respiration is how organisms to exchange oxygen and CO2 with their environment. Cellular respiration is where cells get energy by reacting oxygen with glucose.
Feeding/Digestion is how heterotrophs get and absorb food/energy.
Reproduction is how organisms copy themselves.
Circulation works with the respiratory system to distribute oxygen and remove waste.
Homeostasis is process of maintaining a stable body environment, like temperature.
Eubacteria & Archaebacteria are two groups of different microbes in the Protista.
Protista is the kingdom with micro organisms.
Plantae is the classification of all the plants.
Invertebrates are animals with no spinal structure.
Vertebrates are animals with a spinal structure.
Critical Questions
What do all living things need to do to survive? They need some type of food to maintain body energy, which may involve eating and digesting. All living things need to be able to reproduce. They need to be able to grow and develop in an environment. All organisms need to be able to exchange gases, which could involve breathing air. Finally, they need to be able to dispose waste, more complex organisms using the process of excretion. Our exercise on Comparing Anatomy helped to understand what all living things need to survive. We can use this knowledge to help make sure our surrounding environment remains healthy for other species to survive.
What are some commonalities and differences among living things? Living things include plants and animals. The plants are part of the Plantae kingdom. Some animals are vertebrates or invertebrates. The smaller organisms are classified as Protista, which is split by two groups, Eubacteria and Archaebacteria. Organisms differ in the way they do excretion, respiration, circulation, and reproduction. Organisms are the same in their basic needs to survive. Our Comparing Anatomy worksheets helped understand the commonalities and differences.
