Characteristics of Life: Living things __________, or increase their size. | Grow. |
Characteristics of Life: Living things __________ to changes in the environment. | Respond. |
Characteristics of Life: Living things _____________ to make offspring. | Reproduce. |
Activities by which an organism obtains materials from its environment and prepares them for its use, provides us with energy, growth, and reparation of cells. | Nutrition. |
Autotrophic. | The organism makes its own food, typically through photosynthesis. |
The organism is unable to synthesize organic material from inorganic substances. | Heterotrophic. |
Explain photosynthesis. | Light energy is transformed into chemical energy, then CO2+ H2O , then C6H12O6+O2 (glucose). |
Life Function: Ingestion. | Taking in of food. |
Life Function: Digestion. | Breakdown of food. |
Life Function: Egestion. | The removal of indigestible or undigested food materials, or feces. |
Absorption of materials into the organism and the distribution/circulation of materials within the organism. | Life Function: Transport. |
What are some things that living things transport throughout the body? | Oxygen, water, carbon dioxide, nutrients, minerals, hormones, enzymes, and wastes. |
Chemical processes by which an organism obtains energy from materials in order to obtain its life functions. | Life Function: Respiration. |
With oxygen. | Aerobic. |
Without oxygen. | Anaerobic. |
Two types of anaerobic fermentation. | Lactic acid fermentation and alcohol fermentation. |
ATP. | Adenosine triphosphate, energy from food that can be used by cells. |
The removal of metabolic waste products as a result of metabolic activities. | Life Function: Excretion. |
Examples of excretion. | Carbon dioxide, nitrogenous wastes, urea, water, mineral salts, sweating perspiration. |
The control and coordination of the various activities of an organism, including response to stimuli and cell to cell communication | Life Function: Regulation. |
The chemical activities by which an organism builds larger molecules from smaller ones, simple to complex. | Synthesis. |
Process by which living organisms increase in size through cell division, un-specialized cells become specialized. | Growth. |
Production of new offspring. | Life Function: Reproduction. |
Asexual reproduction. | Mitosis. |
Type of sell division involved with sexual reproduction. | Meiosis. |
All the chemical processes by which an organism carries on its life functions and maintains life. | Life Function: Metabolism. |
Maintenance of a stable, balanced internal environment, all life functions are working properly. | Life Function: Homeostasis. |
