It has a cell wall with silica (note #1 in pic).

chlorophyta
Protista
Chlorophyta
Spirogyra with oxygen bubbles from undergoing photosynthesis
It undergoes sexual reproduction
They are isogamists (sexes unknown)
They have spiraling chloroplasts

chlorophyta
Protista
Chlorophyta
Oedogonium
It is heterogamous
Can tell the difference in sexes
Male gamete- antheridium sperm (#1 in pic)
Female gamete- oogonium egg (#2 in pic)


phaeophyta
Protista
Phaeophyta
Brown Algae Fucus
Some parts they have are: the hold fast, stipe, thallus, air bladder, conceptacles, and receptacles.
The swollen ends are called receptacles.
Receptacles contain the conceptacles, represented by little dots on the end.
Inside the conceptacles are the antheridium and oogonium.

chlorophyta
Protista
Chlorophyta
Spirogyra
It undergoes sexual reproduction or conjugation.
It has spiral chloroplast.
They are isogamies- The sexes can not be distinguished.

algae
Protista
Algae
It is found in damp shaded environments.
They are formed from spores.

The adult algae are non-motile.
They have chlorophyll (photosynthesis)
They are autotrophic
Varieties of sizes.
