Unit 1: Lectures 1-8 Flashcards
Biosphere level
Variety in landscape
ecosystem diversity
Which organelle does cellular respiration
Mitochondria
variety of life
biodiversity
Distinct types of material of which animals and plants are made, consisting of specialized cells and their products
Tissue
Organisms that produce their own nutrients from inorganic substances or from the environment instead of consuming other organisms (producers)
autotrophs
Different types of biodiversity
Genetic
Species
Ecosystem
Group of organisms of the same species living together in a specific geographical location
Population
Organisms that obtain organic food molecules by eating other organisms or their byproducts and that cannot synthesize organic compounds from inorganic material (consumers)
heterotrophs
Molecules that do not have carbon and are normally found in non-living things
inorganic molecules
Synthesis of organic compounds by bacteria or other living organisms using energy derived from reaction involving inorganic molecules, typically in the absence of light
Chemosynthesis
Which organelle does photosynthesis?
Chloroplast
Coordinated activities of multiple organs
System
Flow of information to make proteins
DNA –> RNA –> Protein
What is the purpose of cellular respiration?
Produce ATP using chemicals as initial energy source
7 Properties shared by all living things
Order
Regulation of internal environment
Growth and development
Energy processing
Response to the environment
Reproduction
Evolutionary adaptation
2 or more atoms held together by chemical bonds and are the smallest level of organization
molecule
Cells containing a nucleus and other membrane bound organelles which includes eubacteria and archaebacteria
eukaryotes
At the global level, which areas have the highest and lowest diversity
Highest: equator
Lowest: Poles
The importance of water and hydrogen bonds
Hydrogen bonds make liquid H2O cohesive and adhesive
Hydrogen bonds help to moderate water temperature
Ice is less dense than liquid water
Water is the solvent of life
Cells that lack a nucleus and other membrane bound organelles which includes bacteria, cyanobacteria, and archaea
Prokaryotes
The first level with all living properties
Cell
What level does evoltion occur on?
Population
Biotic components (all living organisms)
Community
Composed of carbon atoms in rings or long chains, to which are attached to other atoms of such elements as hydrogen, oxygen, nitrogen
Organic molecules
Biotic and abiotic components (all living and nonliving organisms)
Ecosystem
Important benefits of human beings arise from healthy functioning ecosystems, notably production of oxygen, soil genesis, and water detoxification
ecosystem service
All environmental supporting life on earth
Biosphere
Group of tissues organized into structures with specific functions
Organ
Why should biodiversity be conserved
Biodiversity provides ecosystems with services such as medical applications, production of goods, production of oxygen, recycling of nutrients, water filtration, and shoreline protection
Roles of biology and technology in society
Biology studies the natural world
Technology applies scientific knowledge for a purpose
Society determines applications and is affected by increase in technology
What is the purpose of photosynthesis?
Produce glucose using the sun as initial energy source
Multiple systems working together
Organisms
Organic vs inorganic molecules
Organic molecules are carbon based while inorganic molecules are not
Population level
Variation of genes among individual species
genetic diversity
Structure with a specific function inside cells
organelle
Community level
Variety of species in a geographic location
species diversity
Diffusion of water across a semipermeable membrane
Osmosis
Smallest level with living properties
Cell
