It is microscopic and is mostly a golden color.
It has a cell wall with silica (note #1 in pic).
Spirogyra with oxygen bubbles from undergoing photosynthesis
It undergoes sexual reproduction
They are isogamists (sexes unknown)
They have spiraling chloroplasts
It is heterogamous
Can tell the difference in sexes
Male gamete- antheridium sperm (#1 in pic)
Female gamete- oogonium egg (#2 in pic)
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.
It undergoes sexual reproduction or conjugation.
It has spiral chloroplast.
They are isogamies- The sexes can not be distinguished.
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.
Their parts: 1) The conjugation tube, 2) The antheridia, & 3) The oogonium
They reproduce asexually
They are isogamic
They have sexual reproduction
1) Conjugation tube
Binary Fission is occurring in the slide.
Has cilia hairlike motion.
