Biology
All Cells
Are enclosed by a membrane
Ecology
Both organisms and their environments are affected by the interactions between them
Structure and function
Closely related in organisms EX: a leaf is thin and flat, maximizing the capture of light by chloroplasts
Prokaryotic Cell
DNA, No Nucleus, Membrane
Ecology
Every organism interacts with its environment, including nonliving factors and other organisms
Nature does not easily change that which works.
Important Fact about nature
Metaboliz, Respond, Grow, Reproduce, Evolve
MR. GREy
Eukaryotic Cell
Membrane, Cytoplasm, Organelles, Nucleus Contains DNA
Characteristics of Life
Metabolize, Respond, Grow, Reproduce, Evolve
Work
Requires a source of energy
Light, Chemical, Kinetic, or Thermal
The different forms of energy
Biology
The study of life
Biological Organization
The study of life can be divided into different levels
DNA
The substance of genes
All Cells
Use DNA as their genetic information
Evolution
accounts for the unity and diversity of life
Emergent properties
characterize nonbiological entities. -EX; a functioning bicycle emerges only when all of the necessary parts connect in the correct way
Chromosomes
contain most of a cell's genetic material in the form of DNA (deoxyribonucleic acid)
Way energy flows through an ecosystem
entering as light and exiting as heat
Emergent Properties
result from the arrangement and interaction of parts within a system in an unpredictable manner
The Ability of Cells to Divide
the basis of all reproduction, growth, and repair of multicellular organisms
Cells
the lowest level of organization that can perform all activities required for life
Evolution
the process of change that has transformed life on Earth
Genes
the units of inheritance that transmit information from parents to offspring
Evolution
unifies biology at different scales of size throughout the history of life on Earth
