THE CHARACTERISTICS OF LIVING THINGS 4. the ability to reproduce and grow. 5. all living things have limited lifespans 6. respond to their surroundings, is extremely important. THE CHARACTERISTICS OF LIVING THINGS 7. organisms respond to their surroundings, namely, through their ability to move. 8. they are able to repair injuries to themselves, provided the damage is not too severe. 9. they can undergo change over time. We know from discoveries of ancient fossilized organisms that life appeared on earth about three and one-half billion years ago. CLASSIFICATION Classification involves placing organisms that share the same traits into the same groups. KINGDOM MONERA The very simplest living things belong to the Kingdom Monera. microscopic size. There are about 3000 different types, or species All monerans are unicellular they lack a nucleus. can be either autotrophic or heterotrophic. KINGDOM PROTISTA consists of microscopic plant-like and animal-like creatures has about 30,000 species. unicellular They have a nucleus, but lack cell walls. Both Autotrophic and heterotrophic KINGDOM PLANTAE multicellular organisms Plant cells have both a nucleus and a cell wall. Plants are autotrophs and are able to use the sun's energy to make their own food. There are about 285,000 species of plants KINGDOM FUNGI the mushrooms, molds, and yeasts— are also multicellular organisms. However, unlike plants, fungi are heterotrophs and cannot make their own food. There are about 100,000 species of fungi. KINGDOM ANIMALIA over one million species of animals. Animals are heterotrophs and cannot make their own food. Like plants and fungi, animals are multicellular organisms, but animal cells lack cell walls and have just one nucleus. QUIZ: TRUE OR FALSE 1 .Heterotrophs can make their own food. 2. Plants are multicellular organisms. 3. Bacteria are Monerans. 4. Homeostasis means maintaining a balanced internal environment. 5. Mushrooms belong to the Kingdom Protista
