Processes of life un unicellular organisms (mnemonic device)

Biology

Metabolism

All of the enzyme-catalysed reactions

Reproduction

Production of offspring

Sensitivity

React to stimuli in the environment with various responses

Homeostasis

Maintaining a sable internal environment

Excretion

Removal of waste products

Nutrition

Getting the nutrients required for growth/maintanance

Growth

Increasing in size or number of cells

Unicellular Organism

1 cell is responsible for all functions promoting of life

Multicellular Organism

cells specialize and carry out their respective functions so that the organism as a whole can carry out functions of life.

Paramecium (unicellular)

contractile vacuole; remove excess water, cilia; movement responding to stimulus, food vacuole; enclosure holding food, cytoplasm; metabolic reactions, nucleus; DNA

Chlamydomonas (unicellular)

Flagella; movement responding to stimulus, Nucleus; DNA, Chloroplast; nutrition (photosynthesis), contracile vacuole; remove excess water, eye spot; sense light
