Characteristics Of Life Quiz 1 Flashcards
What is organization?
Organization is a sign of life when all living things are composed of molecules to organize to cells
EX} atoms to molecule to cells
What is energy?
Living things need energy to function and survive. Energy can be stored for transferring and storing energy in the cell
What is replication?
This is a goal of cells, cells replicate and arise from other cells
EX}DNA, GENES,HEREDITARY
What are cells?
Cells make up an organism and are the most basic unit of life
What is information?
Information is the process of organisms encoded and processed and passed on
What is biology? Why is it important to study?
Biology is the study of life it is important to study because we obtain knowledge of life works and what is considered life
What is a characteristic of life?
A characteristic of life is the continual maintenance of complex structure
What is evolution?
Is a change in the characteristics of a population overtime.
What is growth development?
It is something that defines life where organisms adapt evolve mature to survive.
What is homeostasis?
Stable chemical and physical conditions in an organism’s cells, tissues, and organs
Can be achieved by: matching conditions of a stable external environment or by active physiological processes
What is the response to environment?
Adaptation
What is an organism?
Any living entity that contains one or more cells
characteristics are as follows: having organization, energy, replication, growth and development, information, evolution, homeostasis, cells.
Why is the cell the smallest unit of life?
The cell is the smallest unit of life because it is the most fundamental building block of every living organism.
What is a prokaryote?
A organism lacking a nucleus and containing relatively few organelles or cytoskeleton components
What is a eukaryote?
An organisms whose cells contain a nucleus, numerous membrane organelles and extensive cytoskeleton
What is adenosine triphosphate?
When hydrolyzed USED TO STORE AND TRANSFER CHEMICAL ENERGY
MOLECULE consisting up of an adenine base, a sugar, and 3 phosphate groups that have high potential energy (ATP)
How is energy important to life?
Energy helps cells/life to stay alive, grow, and reproduce
What is metabolism?
Balance of catabolic and anabolic reactions
Is the activity where cells acquire and use energy as they make and break apart organic compounds
What is anabolism?
Process of chemical receptions that build larger molecules out of smaller molecules and atoms
SMALL to LARGE
What is catabolism?
process that breaks larger molecules into smaller ones
requires an input of energy
LARGE TO SMALL
What is the theory of evolution what does it state?
- Most organisms can produce numerous offspring, but environmental factors limit the number that actually survive and reproduce.
- heritable variations allow some individuals to compete more successfully than others for food, mates, and space
- Successful individuals pass the favorable characteristics to offsprings
- Favorable traits become more common in next generation and less successful become uncommon
- Process of natural selection result in evolutionary change
- Include genetic flow, mutations, genetic drift
What is DNA?
DNA molecules contain instructions for making a new organism
Blue print of life
What is the cell theory?
-most basic unit of life
- all living things one made up of one or more cells
- cells can only come from other cells-
How is the cell theory and the theory of evolution related?
(Relationship between the cell and common ancestry)
Together cell theory and the try of evolution unity in belief that:
1. The cell is the fundamental structural unit in all organisms 2. All species are related by common ancestry and have changed through time in response to natural selection
