 Golden brown algae
 It Floats
 Surfaces of fresh water as well as salt
 Covered by two shells of silica that fit together like a pill box (glass)

Notes: Kingdom Protista Characteristics

part 1

Did you know that the members of the Kingdom Protista are the simplest of the Eukaryotes.
Protists actually lack characteristics.... shared by plants, fungi, and animals. BUT they are NOT .... Bacteria.

known as a "Left - Over" organism.

Protista Classification

  • To be evolved 1.7 billion years ago
  • The Eukaryotic contains membrane bound nuclei and membrane bound organelles.
  • UNICELLULAR
  • they mostly live in aquatic habitats:

o Ponds

o Drops of water in soil

o Digestive tracts of animals

· Some can function as Parasites

· May have qualities of both animals and plants

o Did you know…. That some protists can make their own food through photosynthesis; phytoplankton is autotrophic. Others take their food from an outside source; zooplankton is heterotrophic.

o “Animal- like” protista
