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
