Chapter 1 Flashcards
Adaptations
Traits that make an organisms survival chances greater
Aerobic
extracting energy with O2
Anerobic
extracting energy without O2
Archaea
singled celled organism-no organelles-no nucleus
Bacteria
single celled organisms-no organelles-no nucleus
Binomial Nomenclature
the unique two part name of a species, written as: genus-species
Biology
Study of Life
biome
major ecosystem that encompass a large geographic area with distinct physical features and communities
Biosphere
Global ecosystem, encompasses all biomes
Community
All populations in a given area
DNA
The molecule that carries the code for life, made up of long strands of nucleotides
Ecosystem
The living and non living parts of an area
eukaryotes
single or multi celled organisms, have nucleus and organelles, arose from archaea, domain eukarya
Gene
Segments of DNA that code for a specific protein
Genome
All the DNA in a single organism
Metabolism
The sum of chemical reactions in an organism
Nucleic Acids
Large molecules that store and express genetic information
Nucleotide
The basic structures that form Nucleic acids
Nucleus
The membrane bound structure that holds the chromosomes, which hold DNA
Organ
structure made of tissues designed to carry out a specific function
Organ System
Organs connected physically or chemically that work together
Photosynthesis
The process of converting sunlight into usable energy
Prokaryotes
Single celled-no nucleus-no organelles, domain bacteria and archaea
Population
A group of organisms of the same species that can breed with each other
Protein
Biomolecules made up of amino acids
Protists
Eukarya based organisms that are not plants, animals, or fungi
tissue
collection of specialized cells that function to make a specific task more efficient
4 Kingdoms
Protista, Fungi, Animalia, Plantae
3 Domains
Archaea, Bacteria, Eukarya
How do we know if something is alive?
Uses energy-can reproduce grow and develop, cellular organization, maintains internal consistency, Evolves
Life order (atom-biosphere)

Homeostasis
the process by which a cell or organism maintains an internal consistency
