Matching Pairs Characteristics Life MatchOnline version In this game you will match the characteristics of life to their description. by Joanna Hillman 1 Energy Processing 2 Sensitivity or Response to Stimuli 3 Adaptation 4 Organisms are highly organized 5 Regulation 6 Growth and Development 7 Homeostasis 8 Evolution 9 Reproduction Organisms are able to maintain internal conditions within a narrow range almost constantly, despite environmental changes Some organisms capture energy from the sun and convert it into chemical energy in food (photosynthesis); others use chemical energy in molecules they take in as food (cellular respiration). Plants can bend toward a source of light, climb on fences and walls, or respond to touch. Tiny bacteria can move toward or away from chemicals. The diversity of life on Earth is a result of mutations, or random changes in hereditary material over time. These mutations allow the possibility for organisms to adapt to a changing environment. An organism that evolves characteristics fit for the environment will have greater reproductive success, subject to the forces of natural selection. As an environment changes, natural selection causes the characteristics of the individuals in a population to track those changes. Genes provide instructions that will direct cellular growth and development, ensuring that a species’ young Single-celled organisms duplicate their DNA, and then divide it equally as the cell prepares to divide to form two new cells. Multicellular organisms often produce specialized reproductive germline cells that will form new individuals. Inside each cell, atoms make up molecules; these in turn make up cell organelles and other cellular inclusions. In multicellular organisms similar cells form tissues. Tissues, in turn, collaborate to create organs (body structures with a distinct function). Organs work together to form organ systems. Even the smallest organisms are complex and require multiple regulatory mechanisms to coordinate internal functions, respond to stimuli, and cope with environmental stresses.
