17
Q

What color are diatoms?

A

Brown, golden-brown, and yellow-brown algae

18
Q

What are diatoms pigments called? And what color does it produce?

A

-fucoxanthin
-Brown, golden-brown, and yellow-brown algae

19
Q

what kind of algae is sea weed?

A

Brown algae

20
Q

What pigment gives brown algae its color?

A

fucoxanthin

21
Q

What are the parts of the brown algae Nereocystis kelp from bottom to top?

A

starting at the bottom is the holdfast, then the stipe, then the batter, and then the blades

22
Q

What is the pigment for red algae called?

A

phycobilins

23
Q

What pigments are green algae involved with?

A

chlorophyll a, b, and carotenoids, beta-carotene, and xanthophylls

24
Q

What kind of organisms are green algae?

A

Unicellular, colonial, and multicellular organisms

25
Q

Blade

A

the flattened analog of a leaf in many seaweeds

26
Q

Coenocytic

A

an organism whos cell(s) contain multiple nuclei

27
Q

colonial

A

An organism actually made up of multiple organisms. in algae, these individual organisms are typically unicellular and they stick to one another by a gelatinous matrix they secrete

28
Q

Eyespot

A

A patch of pigment on a membrane inside a cell that can detect light. these are typically red and found only in motile algae since the cell once it can detect light can swim toward or away from it.

29
Q

Filamentous

A

a organism that is long and thin (sometimes branching) and typically made up of a string of cells

30
Q

Holdfast

A

The branching structure at the base of many seaweeds that holds them to a substate.

31
Q

Motile

A

to have direct mobility

32
Q

Pneumatocyst

A

an air-filled bladder-like organ on many seaweeds that functions for buoyancy to keep the blades afloat in a position to intercept sunlight

33
Q

Protist

A

a eukaryotic organism classified traditionally in the kingdom Protista: lacking the characteristics of members of plant, animal or fungal kingdoms

34
Q

Pyrenoids

A

Centers of carbon dioxide fixation or starch synthesis within the chloroplasts of algae and hornworms, visible because of the density of enzymes in that region. Pyrenoids are not membrane bound organelles, but specialized areas of the chloroplast that contain high levels of enzymes. A pyrenoid typically has several starch grains near it.

35
Q

what is a macroscopic marine alga?

A

seaweed

36
Q

Stipe

A

the stalk between the holdfast and the blades of may seaweeds
