it means “false feet”
pseudopodia
Amoeba belongs to phylum ___
Sarcodina
When conditions such as dryness, coldness, or lack of food arise, amoebas become inactive and withdraw into a round mass called a __
Cyst
How do amoebas reproduce?
Binary Fission
These are complex protozoans
Paramecium
Paramecium belongs to the phylum ___
Ciliophora
Species of Paramecium live mainly in ____
quiet or stagnant ponds
The paramecium cell is shaped like a ___
slipper
How does a paramecium move?
by means of hairlike threads of cytoplasm called cilia.
Trial and error response in the Amoeba
Avoiding Reaction
Euglena belongs to the phylum ___
mastigophora
Several species of Euglena live in ___
ponds and streams
Shape of Euglenas
oval or pear
Euglena swims by means of what?
flagellum
Euglena’s contraction and stretching are caused by specialized ___ in the cell.
contractile fibers
most striking feature of the euglena
presence of many oval chloroplasts spread through the cell
Plasmodium belong to the phylum ___
Sporozoa
This is the organism that causes malaria in human beings and other warm-blooded animals.
Plasmodium
All fungi are alike in one important way:
lack of chlorophyll
This phylum includes the slime molds, which lack cell walls.
phylum myxomycophyta
phylum of fungi that have cell walls
phylum eumycophyta
the alga-like fungi.
Phycomycetes
the sac fungi.
Ascomycetes
the club fungi
Basidiomycetes
the imperfect fungi.
deuteromycetes
All true fungi that cannot be placed in one of these classes are grouped in this class
deuteromycetes
These include such types as molds, mildews, blights, yeasts, mushrooms, and others.
eumycophyta
The bodies of most true fungi are made up of branching filaments called ___
hyphae.
The whole mass of hyphae formed by a fungus
mycelium
These Phycomycetes, like bread mold, have tube-like hyphae without cross walls.
water molds (under Saprolegnia)
Blue-green molds and powdery mildews.
Ascomycetes
In Ascomycetes, molds of the genus ___ often form blue- green growths on oranges, lemons, and other fruits. They also appear on bread, meat, leather, and cloth.
Penicillium
In Ascomycetes, molds of the genus ____ are common on foods, too, forming yellow or black rings.
Aspergillus
Surface hyphae form branches known as
conidiophores.
They get their name from the club-shaped basidium found at the end of certain hyphae.
Basidiomycetes
Enumerate the groups of fungi that make up the class Basidiomycetes.
Rust fungi, smut fungi, mushrooms, and bracket fungi, and puffballs.
They are like giant masses of amoebas and thus, might be classified as animals
Slime Molds (Phylum Myxomycophyta)
they also form sporangia and spores, like fungi.
Slime Molds (Phylum Myxomycophyta)
Slime molds have also been referred to as _____
slime fungi or fungus animals
The body of a slime mold
plasmodium
It is a mass of protoplasm with many nuclei but no cell walls.
plasmodium
It often appears as a slimy network of living matter.
plasmodium
