Protozoa

Front 1

Kingdom Protozoa includes Unicellular organisms

Back 1

Greek----> Proto=First

Zoa-Animals

so Protozoa= First Animals

Hint 1

Unicellular means they have one cell, they are single celled but they act as a complete animal, doing all basic things.

Front 2

They are Eukaryotes

Back 2

Meaning (True Nuclei) in Latin

Front 3

It includes four groups

Back 3

1. Ciliophora (Ciliated protozoa)
2. Mastigophora (Flagellated protozoa)
3. Sacrodina (Amoeboid Protozoa)
4. Sporozoa (Spore-forming Protozoa)

Hint 3

According to their locomotary organs.

Front 4

Many live as solitary individuals, while a few live in colonies.

Back 4

Solitary=Alone
Colony=Groups

Front 5

Cytoplasm made of 2 regions

Back 5

1.Ectoplasm: Outer, thin region with gelatinous material.

2.Endoplasm: Inner, more fluid granulated region.

Front 6

Most of the species have one nucleus in the cytoplasm, others have 2 or more.

Back 6

When more than 1 nuclei are present they're either monomorphic (similar) or dimorphic (not similar)

Hint 6

Monomorphic= One kind/type

Dimorphic=Two kinds/types

Front 7

Respiration and excretion are mainly carried out by diffusion through the body surface or through the contractile vacuoles in the cytoplasm.

Back 7

Contractile vacuoles control the osmo-regulation and volume-regulation of the body and they are usually found in organisms that live in fresh water.

Front 8

They reproduce sexually or asexully

Back 8

two groups reproduce sexually and asexually, the other two groups reproduce only asexually.

Front 9

Some are parasitic and others are free living.

Back 9

Free living in water (Both salt or fresh water) or in damp soil.

Front 10

Some form a cyst under unfavorable conditions and secret a tough protective membrane around itself, however under favorable conditions, the organism excyst and become active.

Back 10

Encystment: Forming a cyst

Excystment: When the organism excyst.
