Levels of Organization in Living Things
All living things are made of these
What are cells?
The process by which plants make their own food by converting light into chemical energy.
What is photosynthesis?
Results in an exact copy of an organism.
What is asexual reproduction?
Scientific explanation of how and why a phenomenon like evolution occurs.
What is a theory?
Number of organisms of the same species in a particular area.
What is a population?
Groups of similar cells form these in multi-cellular organisms.
What are tissues?
The reactants of cellular respiration.
What are oxygen and glucose?
Results in greater variation among offspring.
What is sexual reproduction?
Theory of evolution explains this.
How the genetic composition of species' populations change over generations.
The different populations of living things that live together in the same ecosystem are called this.
What is a community?
Organ system that moves oxygen into our bodies and removes carbon dioxide.
What is the respiratory system?
The reactants of photosynthesis.
What are carbon dioxide & water?
A permanent change in the DNA sequence that makes up a gene of an organism.
What is a mutation?
Mutations that are beneficial are called this.
What are adaptations?
What are abiotic factors?
The powerhouse of the cell.
What are mitochondria?
What is the product of cellular respiration (that cells use for energy)?
ATP - adenosine triphosphate
X shaped structures inside the cell's nucleus which are made up of long molecules of DNA.
What are chromosomes?
Helps species adapt and survive changes in the environment.
What is genetic variation?
Three types of species interactions in which at least one species benefits.
What are mutualism, commensalism, and parasatism?
Two organelles in plant but not animal cells.
What are chloroplasts and cell walls?
The 2 in H2O or CO2 or the 6 and 12 in C6H12O6
What are the number of atoms of each element of the molecules that react in photosynthesis & respiration?
Different forms of a gene.
What are alleles?
Four key pieces of evidence that support the theory of evolution.
What are comparative anatomy, DNA, embryology, and fossils?
Model used to show energy flow as well as the complex interactions between species in ecosystems.
What are food webs?
