Algae produce energy by
photosynthesis.
are an important source of food, iodine, fertilizers, emulsifiers, and stabilizers and gelling agents for jams and culture media.
Algae
are non-photosynthetic, eukaryotic organisms.
Protozoa
one genus of algae, is a very rare cause
of human infections
Prototheca
Protozoa do not have cell walls, but some possess a thickened cell membrane called, which serves
the same purpose – protection.
CYST
A typical protozoan life cycle has two stages
trophozoite and a cyst
is the motile, feeding, dividing stage
trophozoite
is the nonmotile, dormant, survival stage
cyst
The study of fungi is called
mycology
scientists who
study fungi are called
mycologists
Fungal cell walls contain a polysaccharide called
Chitin
Some fungi are unicellular, while others grow as filaments called
hyphae
Hyphae intertwine to form a mass called a
mycelium
There are two general categories of spores
*Sexual spores
*Asexual spores (also called conidia)
Individual yeast cells, also referred to as
- can be observed only using a microscope
blastospores or blastoconidia
