What are protist

Eukaryotes that don't really fit into a group they are widely diverse, many are unicellular but some a re multicellular, most of them are aquatic

Types of protist

Animal like heterotrophs get nutrients by ingesting food also called protoza



Plant like autotrophs get nutrients performing photsynthesis using sunlight to make oxygen and sugars


Called as protophyta



Fungus like protist are also hetertrophs get nutrients by absorbing food

Endosymbiosis in protist

Basically explains the idea that one cell engulfed another cwll, and explains the evolution of eukaryotic cells, and specifically the prescence of chloropladt and mitochondria cells



The theory propses that mitochondria was engylfed first and later a cell that was capable of photosynthesis was engulfed cyanobacteria

Evidence of endosymbiosis

Mitochondira and chlorplast are similar sixe to bacteria



Mitochondria and chloroplast have their own membrane and ribosomes just like prokearyotes such as bacteria homologous



Reproduction


Mitochondria reproduce just like bacteria binary fission and contain ciruclar dna molecules like chromosomes of bacteria

Which two protist ingest food or absorb as chemoautotroph

Ingest amobea


Absorb slime mold

Which protist is a photoautotrpoh

Euglena and macrocstitis

Reproduction

A or sexually

Euglenoids or eglena

Unqiue algae with unique cell covering aka pellicile (alloe the cell to change shape easily as flagella propel cell through water, eyespot is sensitive to loght and helps to propel directiom of movement)and are photoautotrophs.

Paramecium

entire body is covered with cillia, and are heterotrophs capable of both a and sexual reproduction

Phaeophyta

Brown algae are uniqur they have a thallus structure and are equipped with gas bubbles that keep them to the top of surface for photosynthesis, they have accessory pugments which allow to absorb blue and green light

CPR

Chlorophyta


Rhodophyta


Phaeophyta

What is the name of red and green algae

Archaeplastida

What is the chlorophyll name of rhodophytes

Phycoerythrin pigment allows them to absorb blue and green light which penetrates farinto water

Green algae

Live symbiotically with other plants due to its geeen pigment can photosynthesize and give output to their host

How do chlorophytes evolve

Formation of colones as seen in volvox, filamentous forms which contribute to stringy mass known as pond scums


Formatiom of multicellular bodies celldivisin of nucleic with no cyptoplasm

What are the name sof protist whuch are closely related to animals and fungi

Unikonts

Plasmodial slime molds

Formed mass called plasmodium sungle mass of cyptoplasm undivided by plasma membrane. Help distribute oxygen through moist soil function in sexual reproduction

Difference in cellular slime molds

Reproduce asecuall


Commonlymfound on forest floors
