Properties of life

Properties of life

ordered systems, response to stimuli, reproduction, adaptation, growth and development, homeostasis, metabolism, and evolution.

Ordered systems

Increasing complexity and size: organelles, cells, tissue, organs, organ systems, organism, population, community, ecosystem, biosphere.

Response to stimuli

Living things react to environment either towards (positive) or away (negative)

Chemotaxis

response to chemicals

phototaxis

response to light

Reproduction

the ability to create offspring; asexual or sexual

Adaptation to environment

Organisms more likely to survive and thrive will pass on those traits to their offspring

Grow and develop

organisms acquire resources and increase in size over time

Homeostasis

a living organism’s ability to maintain a stable internal environment using internal mechanisms.

Metabolism

all living things consume energy by converting sugar to ATP then use the sugar via cellular respiration

Evolution

Change over time in living population to better survive in the environment
