🗑
|
||||
| if the zooflagekllate is a protist they might live in... | mutualism
🗑
|
||||
| mutualism | where one organism lives closely with another helping each other to live
🗑

🗑
|
||||
| macronucleus | the larger nucleus that controls the functions of the cell
🗑
|
||||
| micronucleus | smaller nucleus that passes genetic info to another paramecium during sexual reproduction
🗑
|
||||
| what are water molds? | decomposers or parasites
🗑
|
||||
| heterotrophs that can't move are.. | spore-forming protists
🗑

🗑
|
||||
| binary fission | single celled protist divides into 2
🗑
|
||||
| multiple fission | make more than 2 offspring from one parent
🗑
|
||||
| what uses sexual reproduction? | paramecia
🗑
|
||||

🗑
|
||||
| Can protist reproduce both ways? | yes, some alternate between generations while some depend on environment (like slime mold)
🗑
