Bio Chapter One

Cellular Organization

All organisms consist of one or more cells. Each cell is bounded by membranes that separates the organism from its surrondings.

Characteristics of Living Organisms:

Cellular Organization, Ordered Complexity, Sensitivity, Growth Development & Reproduction, Energy Utilization, Homeostasis, Evolutionary Adaptation

Ordered Complexity

All living things are complex and highly ordered, your cells contain many complex molecular systems.

Sensitivity

All organisms respond to stimuli. Human’s pupils dilate when in the sun and plants grow towards sources of light

Energy Utilization

All organisms take in energy and use it to perform work.

Homeostasis

All organisms maintain relatively constant internal conditions that are difficult from their environment.

Evolutionary Adaptation

All organisms interact with other organisms and nonliving things for their survival and therefore, organisms as a whole adapt to their environments.

Cellular Level

Atoms are bound together to make molecules, which are assembled into organelles.

Organism Level

Tissues are groups of simillar cells bound together, which form organs, which form
