unicellular algae description
- contain chlorophyll and carry out photosynthesis = autotrophic
- accessory pigments help absorb light, give algae a variety of colours
euglenophytes
=krásnoočka
- autotrophs when sunny
- heterotrophs when dark
- unicellular
- found mostly in fresh water
- some have flagellum
chrysophytes
= zlativky
= golden algae, fresh water
- with flagella
- facultatively heterotrophic (lack of light)
- forms: free swimming, filamentous, colonial
diatoms
= rozsivky
- unicellular
- glasslike cell walls
- used in toothpastes, scouring products, and as filters (swimming pools)
dinoflagellates
= obrněnky
- unicellular
- covered in stiff plates
- have 2 flagella
- may glow in the dark
- found in the ocean
multicellular algae description
- relatively simple aquatic organisms
- able to photosynthesis (produce oxygen)
- dont have leaves, roots, flowers. vascular tissue - have phyla
- live in damp places (fresh and saline water), but can endure dryness and other conditions in symbiosis with a fungus as lichen
- contain chlorophyll-a and other photosynthetic pigments

multicellular algae are
relatively simple aquatic organisms
multicellular algae are able to
photosynthesize - produce oxygen
multicellular algae dont have
roots, flowers, vascular tissue - have phyla
multicellular algae live in
damp places(fresh and saline water), but can endure dryness and other conditions in symbiosis with a fungus as lichen
damp places
slightly wet, moist - vlhký
multicellular algae contain
chlorophyll-a and other photosynthetic pigments
importance of algae
- free floating phytoplankton provide the food base for most marine food chains
- some are used as human food
- harvested for useful substances such as agar or fertilizer
fertilizer
hnojivo
the study of marine algae
phycology or algology
symbiosis
- algae that enter into symbiosis with fungus are called lichens
- the stony corals which construct coral riffs formed a symbiotic partnership with single-celled algae called zooxanthellae
reproduction of algae
sexually and asexually
asexual reproduction of algae
by fragmentation and by spores (motile and non-motile)
sexual reproduction of algae
by the fusion of gametes
forms of reproduction of algae
isogamy, anisogamy, oogamy
isogamy
equal-sized motile gametes
anisogamy
motile gametes, different sizes
oogamy
small motile male gamete, large non-motile female gamete
life cycle
eukaryotic algae groups
chromophyta, rhodophyta, chlorophyta
chromophyta
brown algae
rhodophyta
red algae
chlorophyta
green algae
Chromophyta are mostly
Marine algae, including many seaweeds
Chromophyta contain
The pigment fucoxanthin - greenish-brown colour
Chromophyta storage material
Laminarin
Chromophyta usage
Eaten by Japanese, stabilisers in ice cream, toothpastes
Chromophyta examples
Seaweed, kelp
Seaweed, kelp
= chaluha
- multicellular, the most complex, developed anatomy of all the algae
Rhodophyta
- mostly multicellular, marine algae, including seaweeds
- most of the coralline algae
- traditional part of European and Asian cuisine (vitamins, proteins)
- used to make other products like agar, food additives
- can occur down to 200 metres
- contain the pigment phycoerythrin = reflects red light and absorbs blue light
- floridean starch - storage material (energy)
- typically live attached to surfaces rather then floating
Rhodophyta mostly
Multicellular, marine algae, including seaweeds
Rhodophyta examples
Coralline algae
Rhodophyta usage
- traditional part of European and Asian cuisine (vitamins, proteins)
- used to make agar and food additives
