Q

It proposes that smaller prokaryotes entered into a symbiotic relationship with a larger prokaryote for protection. In return, the smaller prokaryote provided the ability to produce energy or motility for the larger organism. This relationship would have given the “new” organism an evolutionary advantage over the existing prokaryotes. This advantage led to the evolution of the Domain Eukarya and eventually over hundreds of millions of years to the Kingdoms Fungi, Plantae, and Animalia.

Q

supporting evidence for the endosymbiotic hypothesis

A

Mitochondria, Chloroplasts, Flagella

17
Q

These are Bi-flagellated organisms. Most of these organisms are Mixotrophic. (They can photosynthesize and also are heterotrophic.) They have a red eye spot that helps in detecting sunlight.

A

Euglenozoa

18
Q

These organisms contain small air –filled chambers called alveoli.

A

Alveolata

19
Q

Most are phytoplankton.

Example - Red Tide (These are toxic to most mollusks, fish, and humans.)

A

Dinoflagellate (type of Alveolata)

20
Q

Produce a yellow-brown, energy rich oil. Have a strong outer shell composed of silica. (They look like stained glass.) Important phytoplankton. (In food chains, they are major producers.)

A

Diatoms

21
Q

A.K.A. Sea weed or kelp. Produce a brown, light absorbing pigment that contains Iodine

A

Phaeophyta

22
Q

Most move using Pseudopodia “oozing”. (“pseudo” means “false”; “poda” means “foot”) These catch and eat other organisms, just like animals. Ex. Amoebas

A

Animal-like Protists (protozoa)

23
Q

Most are free-living organisms and have no “real shape”.

A

Amoebas

24
Q

These feed on decaying organisms as they are decomposers.

A

Fungus-like Protists (Mycetozoa)

25
Q

These organisms perform photosynthesis, just like plants.

A

Plant-like protists
