One imaju ulogu proizvođača te proizvode 80% kisika na Zemlji.
Neke alge stvaraju velike podvodne šume i sklonište brojnim drugim morskim organizmima, ali danas ću pisati o crvenim algama.]]> 2022-11-16 16:20:56 UTC https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386890548 anabrezovic3 https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386892574 2022-11-16 16:22:08 UTC https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386892574 anabrezovic3 https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386898735 Crvene alge su uglavnom višestanične, što znači da se nazače na više različitih mjesta na Zemlji.
Većinom žive u toplim morima i prićvršćene su na stijene, ali mogu biti prićvršćene i na morsko tlo.
Crvene alge zahvaljujući svojim pigmentima mogu iskorištavati svjetlost kratkih valnih duljina koja prodire do dubine preko 200 m te ih to čini algama koje žive na najvećim dubinama od svih skupina algi.]]> 2022-11-16 16:25:42 UTC https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386898735 anabrezovic3 https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386899529 2022-11-16 16:26:11 UTC https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386899529 anabrezovic3 https://padlet.com/anabrezovic3/orjcywacyabchzhx/wish/2386902626 Postoje, naravno razne vrste crvenih alga, kao što su npr.
