2. PROTOZOA
Proto=firstZoa= animal
Protozoa-eukaryotic organisms that consist of one cell
Size: 1um-500um
It can do all biology function
Extremely diverse
Protoplasm contain cytoplasm and one/more nucleus
Cytoplasm divided 2 layer:
i) ectoplasm –movement (pseudopodia), to eat, respiration
and protection
ii) endoplasm –as digestion system ( particle, vacuole and
lysozyme) and osmoregulator

4. Structure of an Amoeba
Unicellular animal with pseudopodsthat lives in fresh or
saltwater.
Pseudopodium-part of the amoeba used for locomotion.
Ectoplasm-vitreous superficial layer of an amoeba.
Endoplasm-central part of an amoeba.
Cell membrane-membrane covering an amoeba.
Contractile vacuole-cavity of the amoeba that is able to
contract.
Food vacuole-cavity of the amoeba responsible for
digestion.
Nucleus-central organelle for an amoeba.
Digestive vacuole-cavity of the amoeba responsible for
digestion.
