Chapter 1 Flashcards
(23 cards)
Multicellular
Having multiple cells
Most living organisms
DNA
Made from genes to form the “Blueprint”
ORGANIZATION and METABOLISM
((AKA: DEOXYRIBONUCLEIC ACID))
Organs
Made from TISSUE,
Makes up ORGAN SYSTEM
EX. Brain, Leaf
Cell
Most basic UNIT of life
Atoms
1
The basic units of matter
Combine to form small MOLECULES
2.1
Smallest part of elements that displays its properties.
Eco-Systems
A COMMUNITY interacting with their Physical environment (Water, land, Climate)
Reproduce
Make another organism like itself
- MULTICELLULAR, Sperm & Eggs
- SINGLE-CELLED, Splits Itself
Development
The stages an offspring undergoes to become an adult.
MULTICELLULAR
Population
All members of one SPECIES in a particular area
Bacteria
Microscopic organisms (widely distributed) Simple structures
Morel
A fungus that digests it’s food externally
Evolution
The way in which POPULATIONS of organisms change over Generations
Molecules
- ATOMS combine to form SMALL
- Within a CELL
- Join to Make up Larger MOLECULES within a cell
Species
A group of similar ORGANISMS that are -capable of inter breeding
Community
All living organisms in an area
Animals & Plants
Metabolic
The chemical change taken place in a CELL for organism to produce energy
Mutations
The obvious difference between SPECIES
—Foundation of Genetic Variation and fuel NATURAL SELECTION
EX: eye color, hair color
Genes
Genetic instructions for REPRODUCTIVE ORGANISMS
Tissue
The product of combing similar CELLS
Make up ORGANS
-MULTI
Adaptation
Modifications that make an ORGANISM, better able to function in a specific environment
Protists
Larger in size
More complex than BACTERIA
Bio-Sphere
All the ECOSYSTEMS on Earth
Behavior
Organism responding to their environment
