Chapter 1 Flashcards
Order
Small components to larger components to make complex unit.
Evolutionary adaptation
Ability to change from generation to next adapt and pass down genes.
Regulation
Homeostasis maintain internal environment, regardless of external environment
Energy process
Turns sugar to useful energy through metabolism and make ATP.
Growth and development
Grow in size or in numbers.
Response to environment
Response to stimuli from environment. Immediate response.
Reproduction
To make offsprings.
The biosphere
Consist of everything in planet earth.
Ecosystem
Desert, tundra, rain forest, grass lands, and coral reefs.
Communities
Array of organisms inhabiting a particular ecosystem.
Population
Specific species living within a specific area.
Organisms
Individual living things.
Organs and organ systems
Organ: the heart
System: respiratory system (2 or more organs working with one common goal)
Tissues
A group of cell working together performing a specialized function.
Cells
Smaller unit that represents life.
Organelles
Mitochondria, Golgi body, lysosomes etc
Molecules
A chemical structure consisting of two or more units called an atom
Taxonomy
The branch of biology that names and classifies species, formalizes the ordering of species into groups of increasing breadth, based on the degree to which they share characteristics.
Taxonomy mnemonic
Species, genus, family, order, class, phylum, kingdom, domain.
King David & Phillip came over from great Spain.
3 domains of life and their kingdoms
Bacteria, Archaea, and Eukarya
Plantae, fungi, protists
Domain bacteria characteristics
Prokaryotes, diverse and widespread, no membrane bound nucleus, single cell, no membrane bound organelles.
Domain archaea characteristics
Prokaryotes, extremophiles, single cell, no membrane bound nucleus, no membrane bound organelles.
Domain Eukarya characteristics
Eukaryotic cells, bigger, more complex, has membrane bound nucleus, membrane bound organelles, mostly multi cell (exception for others)
Charles Darwin
Studied natural selection ; wrote: the origins of species.
