Life Processes

a. Metabolism and Excretion b. Responsiveness c. Movement d. Growth e. Differentiation f. Reproduction

a. Metabolism and Excretion ■ Anabolic reactions

– Building reactions – Consume energy

■ Catabolic reactions – Break materials down – Release energy

■ Normal metabolic operations require: – Absorption – Excretion

Homeostasis

b. Responsiveness

■ Also called irritability

■ Adaptability – Longer-lasting changes

c. Movement

■ Internal

■ External

d. Growth

■ Increase in: – Size – Number

Of cells

e. Differentiation

■ Perform specialized functions

f. Reproduction
