Characteristics of Life Video (ameoba sisters) Characteristics of Life: 1)All organisms are made of cells some organisms are UNICELLULAR (one cell big) and some organisms are MULTICELLULAR (made up of many cells) The organizational levels (hierarchy) from least complex to most complex are: Cell- Tissue- Organ- Organ System- Organism 2) Organisms reproduce to pass on genetic materials (DNA). Asexual Reproduction: One parent creates identical offspring Sexual Reproduction: Two parents combine genetic material to make one unique offspring 3) Organisms Grow and develop over their life cycle. 4) Organisms use energy. Autotroph/Producer: Makes their own food Heterotroph/Consumer: Eats another organism for energy 5) Organisms respond to their external and internal environment. Homeostasis: Responding to a change in the internal environment to maintain balance inside an organism. Ex: sweating when your body is hot 6) Population of organisms adapt to their environment over time. Organisms must posses ALL of the characteristics of life...but they do NOT have to have them all at the same time. (Babies don't have the ability to reproduce but they are still alive) Scientific Method Notes and Vocab: How to make an experiment valid: -Large Sample Size Control Group Experimental Group Repeated Trials 1 independent variable 1 depdendent vararible Keep other variables constant Repeatable Procedures Flash Cards: write the bold words/definitions on flashcards Independent Variable: What is changed by the experimenter in the experimental group The variable the experimenter is changing to see how it affects the dependent variable. Ex: How does the amount of sunlight affect plant growth. The amount of sunlight is the independent variable Dependent Variable: What is measured in the experimental and control group The variable that is measured by the investigator to see how it changes because of the change in the independent variable. DATA. Ex: How does the amount of sunlight affect plant growth...plant growth is the dependent variable. Control Group: A group that is tested as a comparison to the experimental group. Group where you DO NOT change the independent variable, but still measure the dependent variable. This allows you to compare results with the experimental group. Ex: Does a medicine help decrease the # of asthma attacks in asthma patients. The control group is the group of patients who DO NOT receive the medicine. The data collected is the number of asthma attacks these patients have. Experimental Group: Group that is tested to see the affect on the independent variable Group where you change the independent variable and measure the dependent variable. Ex: Does a medicine help decrease the # of asthma attacks in asthma patients. Experimental group are the people who receive the medicine. The data collected is the number of asthma attacks they have while on the medicine. Constant (Controlled Variable): the factors that stay the same between the control group and experimental groups Concentration: The amount of solute in a solvent Solute: a substance being dissolved; ex: the salt in salt water Solvent: a substance that dissolves the solute; ex: water in salt water Solution: the mixture made when a solute dissolves in a solvent; ex: salt water Osmosis : Osmosis is the movement of water from high to low concentration. The reason why salt harms plants and animals is that the water moves out of the cells of the plants and animals. Some plants that live in marshes have adaptations where they store salt inside their cells. This adaptation allows them to have a higher salt concentration inside their cell than in the surrounding water and the water moves into their cells. Diffusion: The movement of any molecule from high to low concentration |
