Is It a Living Organism? Take out a sheet of paper and number it 1-30 Is It a Living Organism? • The following slides show 30 examples of living and nonliving things. • Based on the characteristics of life your group came up with, decide if each example represents a living organism. • If the object shown is a living organism, write “Yes.” • If the object shown is nonliving, write “No.” Tree 1 Rock 2 Slime mold 3 Fire 4 River (the flowing water) 5 Wind 6 Rabbit 7 Cloud 8 Coral 9 Feather 10 Grass 11 Seed 12 Egg (unfertilized) 13 Zygote 14 Spore 15 Bacteria 16 White Blood Cell 17 Molecule 18 Shelf Fungus 19 Sun 20 Probiotic Yogurt 21 Potato 22 Leaf 23 Chloroplast 24 Butterfly 25 Pupa 26 Fossil 27 Hibernating Bear 28 Virus 29 Mitochondria 30 Answers to Is it a living organism? Characteristics of Living Things 1. 2. 3. 4. 5. 6. 7. 8. Living things are based on a universal genetic code. Living things grow and develop. Living things respond to their environment. Living things are made up of cells. Living things reproduce Living things maintain a stable internal environment. Living things get and use material and energy. Taken as a group, living things evolve. Tree 1 Yes Rock 2 No Slime mold 3 Yes Fire 4 No River 5 No Wind 6 No Rabbit 7 Yes Cloud 8 No Coral 9 Yes Feathers are produced by living cells located in small pit-like follicles in a bird’s outer skin layer. 10 Feather As it’s produced keratin is protruded straight out from the skin follicle, enlarging the feather. No Grass 11 Yes Seed Seeds may lay dormant for years before conditions become favorable for germination. 12 Yes Chicken Egg (unfertilized) The yellow yolk is not the egg, but food for the egg. The egg is a tiny single haploid cell found in the egg white. The unfertilized egg is not capable of reproducing or evolving. 13 No Zygote 14 Yes Spore Spores are usually haploid and unicellular. Once conditions are favorable, the spore can develop into a new organism which produces gametes. 15 Spores are part of the life cycle of a diploid organism. They are every bit a living organism as the organism that produces them. Yes Bacteria 16 Yes White Blood Cell 17 Yes Molecule 18 No Shelf Fungus 19 Yes Sun 20 No While yogurt contains live cultures of bacteria, the yogurt itself is not alive. 21 Probiotic Yogurt No Potato One potato can yield many plants. Just cut it into pieces so that each piece contains a bud. Place a potato piece cutside down in a hole, cover it with dirt and apply water. In time, a potato plant will grow. 22 Yes Leaf Many leaves can be cut at the stem and placed back into soil to grow new roots. This is known as propagation. In some cases, the stem isn’t even needed. 23 Yes Chloroplast 24 There is evidence that the ancestor of chloroplasts was once a free-living cyanobacterium that formed a symbiotic relationship with another cell. This merger is believed to have happened about 1 billion years ago. No Butterfly 25 Yes Pupa 26 Yes Fossil Fossils are a remnant or trace of an organism of a past geological age embedded and preserved in the earth’s crust or some natural material. 27 No Hibernating Bear 28 Yes Virus Although viruses have genes and can evolve, they do not have a cellular structure. In addition, viruses do not have their own metabolism, and require a host cell to make new products. 29 No Mitochondria 30 There is evidence that the ancestor of mitochondria was once a free-living bacterium that formed a symbiotic relationship with another cell. This merger is believed to have happened about 2.5 billion years ago. No
