Transcript
Classification:
2 types of cells: Prokaryotes (bacteria), Eukaryotes (plants & animals)
Mammals: breathe air, give birth to live young
Genus-group of species; when a scientist discovers a new species, it is placed with the
species with which it shares the most characteristics
Structure and Function of Living Organisms: From Cells to Organisms
Cells: smallest, or lowest, level of organization of the human body
Organelles/parts: nucleus, cytoplasm, mitochondria, vacuoles, ribosomes,
endoplasmic reticulum, Golgi body, cell membrane (plants: chloplasts, cell
wall)
Diffusion, Osmosis (water), Division (mitosis, meiosis)
Tissues: 4 types-nerve, muscle, epithelial, connective (where are red blood cells made?)
Organs
Organ systems: What are the main parts and functions?
Digestive-digestion, absorption, elimination of waste
Circulatory-transport—waste (carbon dioxide), needed materials
(nutrients, oxygen)
Skeletal-support & structure
Respiratory-Oxygen/Carbon dioxide between air and lungs
Nervous system
(Where does the digestive system connect to the circulatory system?)
(Where does the Respiratory system connect to the circulatory system?)
Properties and Change of Matter: Atoms and Molecules
Atoms, element, molecules, compounds
Inheritance, Variation, and Adaptation: Heredity
Traits, genetics---Punnett Square (Pp xPp), Genotype, Phenotype, reproduction,
variation, diversity
Ecosystems: Flow of Energy through Ecosystems
Biotic, Abiotic
Populations, Communities
Producers, consumers, decomposers
Photosynthesis, Respiration
Pathway of energy through a living system: light energy-chemical energy-heat
Limiting factors-food/water, space, climate
Carrying Capacity-maximum population an ecosystem can support
Adaptation- any heritable characteristic that an organism possesses that improves its ability to
survive and reproduce in its environment
Scientific Inquiry
Question, Variables (manipulated, responding, controlled), Hypothesis, Procedure, Data
Collection (Observation & Recording), Data Analysis, Drawing and writing a conclusion
