Protista

Question 1

Is Protist eukaryotic or prokaryotic?

Answer 1

Eukaryotic

Question 2

Is Protist multi or unicellular?

Answer 2

Can be both

Question 3

How did mitochondria appear in Eukaryotes? How is the theory called?

Answer 3

Endosymbiosis theory states that larger organisms engulfed cells that later became a part of the main cell. One provides nutrients for another, while another produces energy for the first one.

Question 4

Do Protists have cell wall?

Answer 4

Some do, but mostly none.

Question 5

What are characteristics of plant-like Protist? Example?

Answer 5

It does photosynthesis (autotroph), but doesn’t have vascular tissue. Example is green algae, diatoms, euglena.

Question 6

What are characteristics of fungi-like Protist? Example?

Answer 6

They’re heterotrophs, but unlike fungi, fungi-like Protists don’t have a cell wall made of chitin. They’re parasitic. Example will be a slime mould.

Question 7

What are characteristics of animal-like Protist? Example?

Answer 7

They are heterotrophs, can be parasitic, and move using pseudopods, cillia, or flagella. Examples are amoebas and plasmodium.

Question 8

How do protists reproduce?

Answer 8

Both sexually and asexually.

Question 9

How do we know that some organelles (e.g mitochondria and chloroplas) were engulfed cells?

Answer 9

They do binary fission, have similar to prokaryotes cell wall, and have their own DNA.
