organization, growth. metabolism, homeostasis, stimuli response, reproduction, evolution

properties of life

organization

living things are highly organizaed and consists of one or more cells

cells

basic unit of life

tissues

group of cells

organ

group of tissue

organ system

group of organs

prokaryotic

cells with no nucleus

eukaryotic

cells with nucleus

muscle tissue

tissue used for movement

nervous tissue

tissue used for signal

epithelial tissue

tissue used for cover

growth and development

growth by increasing cell number, size, and changing structure and form

metamorphosis

drastic physical changes as organism grow

metabolism

chemical reaction that allow organisms to obtain energy for

growth, reproduction, and maintaining internal balance.

catabolism

breakdown of complex to simple molecules

anabolism

uses energy to make or repair cells and other components

homeostasis

Regulating a stable internal environment between interdependent elements via physiological processes

stimuli response

responses to a stimulus, either light, temperature, sound, touch

This responsiveness helps us survive and adapt to our surroundings

reproduction

all living things have the ability to reproduce

ensures the continuation of the species

sexual

reproduction with a combination of genetic material from two parents

asexual

reproduction involving a single parent

evolution

specis can change over generation

changes improve their chances of survival
