What does a macronucleus do?
it controls a paramenciums metabolism
What does a micronucleus do?
it controls a paramenciums reproduction
How do paramencia feed?
they have an oral groove that is lined with cilia. These cilia sweep food into the gullet through the oral pore. undigested food is expelled through the anal pore.
Paramecia can engage in what and how is it different from bacteria?
conjegation and it's different cause the exchange is mutual.
What are the two types of vacuoles?
Food and contractile
what does the food vacuole do?
it holds and stores food while it is being digested
what does the contractile vacuole do?
it regulates the amount of water in the cell
what is alternation of generation?
it is where different generations alternate between different modes of reproduction
The majority of photosynthesis on earth is done by what?
Phytoplankton.
What is it called when algae reproduce so rapidly that they take over their habitat?
Algal Bloom
Define algal bloom
when algae reproduce so rapidly that they take over their habitat.
Why are green algae called green algae?
Because they have the pigment chlorophyll in them.
What are diatoms?
Different species from phylum chrysophyta.
What is diatomaceous earth?
the cell wall remains of many dead diatoms clumped together.
What is the poisoneous water around some dinoflagellates called?
Red tides
What is in the cell walls of phylum phaeophyta called and what is it used for?
Alginic acid and it is used to make a thickening agent in some foods.
