Chapter 1 Flashcards
Seven properties and precesses are associated with life
1) Order, 2) Reproduction, 3) Growth and Development, 4) Energy Processing, 5) Regulation, 6) Response to the environment, 7) Evolutionary Adaptation.
Biosphere
All of the environments on Earth that support life. (Florida)
Ecosystem
Consists of all the organisms living in a particular area as well as the physical components. (Florida Everglades)
Community
The entire array of organisms in an ecosystem. (All organisms in this wetland ecosystem)
Population
Includes all the individuals of a particular species living in an area. (All Alligators living in the wetlands)
Organism
An individual living thing. (Alligator)
Organ
Made up of several different tissues.(Brain)
Tissue
Each in turn made up of a group of similar cells that perform a specific function. (Nervous tissue)
Cell
is the fundamental unit of life.
Molecule
Is a cluster of small chemical units called atoms held by chemical bonds.
The dynamics of ecosystems include two major processes
1) The recycling of chemicals and 2) The flow of energy
Most basic chemicals necessary for life
Carbon Dioxide, Oxygen, Water, and various minerals.
DNA
is the chemical substance of genes.
Genes
the units of inheritance that transmit information from parents to offspring.
Chromosomes
Genes that are grouped into very long DNA molecules, which control all the activities of a cell.
DNA molecules
made up of two long chains called stands, coiled together into a double helix.
nucleotides
The strands are made up of four kinds of chemical building blocks
Cell Division
DNA is first replicated or coped, the double helix unzips and new complementary strands assemble along the separated strands.
blueprints for making proteins
The DNA of genes
Proteins
serve as the tools that actually build and maintain the cell and carry out its activities.
Genome
is the entire “library” of genetic instructions that an organism inherits.
Bacteria
are the most diverse and widespread prokaryotes.
Archaea
prokaryotes live in Earth;s extreme environments.
Eukarya
all the organisms with eukaryotic cells.
