1 CRCT STUDY GUIDE 7TH GRADE LIFE SCIENCE

2 Investigate the diversity of living organisms; Compare scientifically.
CLASSIFICATION Investigate the diversity of living organisms; Compare scientifically.

3 Physical Characteristics ! !
CLASSIFICATION DICHOTOMOUS KEY SIX KINGDOMS Physical Characteristics ! !

4 ECOLOGY Examine the dependence of organisms on one another and their environment.

5 Changes in environmental conditions can affect survival of species.
ECOLOGY FOOD WEB SYMBIOSIS . . . Changes in environmental conditions can affect survival of species.

6 BIOMES Describe the characteristics of terrestrial biomes & aquatic communities.

7 TELL HOW THEY ARE DIFFERENT !
BIOMES TELL HOW THEY ARE DIFFERENT ! Tropical rain forest, savanna, temperate, desert, taiga, mountain.

8 CELLS Describe the structure and function of cells; Explain that cells take in nutrients.

9 CELLS PARTS OF THE CELL - - cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria

10 HUMAN BODY SYSTEMS Cells are organized & serve the needs cells have for oxygen, food, and waste removal.

11 HUMAN BODY SYSTEMS DIGESTION, RESPIRATION, REPRODUCTION, CIRCULATION, EXCRETION, MOVEMENT, CONTROL, COORDINATION, PROTECTION FROM DISEASE.

12 GENETICS Recognize how biological traits are passed on to successive generations.

13 HEREDITY = DNA GENES & CHROMOSOMES SELECTIVE BREEDING
GENETICS HEREDITY = DNA GENES & CHROMOSOMES SELECTIVE BREEDING

14 EVOLUTION Examine evolution through inherited characteristics that promote ‘survival of the fittest’.

15 ADAPTATION NATURAL SELECTION CHANGES OVER TIME
