Biology Chapter 1 Flashcards
What is Biology?
Biology is the scientific study of life
Organization
How we group things together within the field of biology
Eukaryotic
Contains membrane bound organelles
Aka: Nucleus
These cells contain compartments
Prokaryotic
Do not contain membrane bound organelles
Aka: No Nucleus
Sperm cell
Contains Nuclei DNA
Egg cell
Contain Nuclei DNA
Fertilized Egg
DNA from both parents
Embryo’s cells
Copies of inherited DNA
Offspring
Traits inherited from both parents
Gene expression
The process by which DNA genes directs the synthesis of proteins or RNAs that perform functions in the cell
DNA
Is the blueprint
RNA
Is a copy of the blueprint that is sent to all the workers so they can build the ship
The protein
Is the ship the end product it is what the instructions told you to build
Crystalline
Are Lens cells tightly packed with transparent proteins
Crystalline gene
Is DNA transcription to mRNA translation to chain of amino acids protein folding to Protein
Energy
Life only exist because of the transfer of energy between organisms
The sun
Provides energy to earth
Plants
Use the suns energy to create chemical energy
Animals
Feed on producers and other consumers to acquire energy
Ecosystems
Organisms within an ecosystem interact with sunlight
Feedback
The output or product of a process regulates that very process/ is a method of regulation
Positive feedback
The product of a process promotes the process to continue
Negative feedback
The product of the process stops or deceases the process
Evolution
Species are descendants of ancestral species that were different from the present day species
