Study of Life
How can you tell if an organism is dead?
It doesn’t have the 8 characteristics.
What are the 8 characteristics of life?
Made of cells, reproduction, genetic code, Growth & Development, use of energy and materials, response to environment, maintenance of internal balance, evolution
Cells
Smallest unit of life that are a collection of living matter separated from its surroundings by a barrier (it’s classified as either unicellular or multicellular)
Unicellular
An organism that has one cell
Multicellular
An organism that has more than one cell
Reproduction
Living organisms producing their offspring of the same kind
Asexual Reproduction
Offspring has only one parent (typically cloning)
Sexual reproduction
Cells from two different parents unite to produce the offspring
DNA
determines all of the traits of an organism
Development
division of cells that’ll keep multiplying which helps the cells change shape and structure to become different cells
Energy
is needed for growth, development, and reproduction
Metabolism
a process by which organisms builds up or breaks down materials
Stimuli
Any detectable change in an organism’s internal or external environment that causes it to react
Homeostasis
Same/Steady
Evolution
The long process of an organism changing over time
Virus
Composed of a core of DNA or RNA surrounded by a protein code
How do Virus’ reproduce?
ONLY by infecting living cells to reproduce more viruses
Genetic code of Virus’
DNA/RNA
Are virus’ able grow and develop?
No, they don’t have the cellular machinary to do it
Do Virus’s obtain and use energy?
No, they don’t have cellular machinery to perform metabolism
Do Virus’ respond to the environment?
No, they lack the response to immediately react to stimuli
Are Virus’ able to evolve?
Yes because they have high mutation rates
