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 |
