Marine organisms that photosynthesize and provide energy to the food web are called:
photospores
primary producers
endospores
bateriophages
Prokaryotes do not have
DNA
cell walls
membrane bound organelles
ribosomes
Decay bacteria
photosynthesize sugars
chemosynthesize sugars
use pigments to capture sunlight
break down organic matter and release nutrients
Autotrophic prokaryotes produce sugars by
photosynthesis
chemosynthesis
photosynthesis or chemosynthesis
decaying organic matter
Archaea are known as "extremophiles" because
they can live in very deep water
they can live in really hot water
they can live in really salty water
all answers are correct
Where does photosynthesis take place in photosynthetic bacteria?
chloroplasts
cytoplasm
cell membrane
golgi apparatus
Unicellular algae carry out photosynthesize in their
cell membrane
chloroplasts
cell wall
nucleus
Diatoms have a two part cell wall (frustule) made of
cellulose
silica
lipids
glucose
Diatoms appear golden-brown from this extra photosynthetic pigment
chlorophyll
phycocyanin
phycoerythrin
carotenoid
These are the most important temperate and polar open-water primary producers
diatoms
dinoflagellates
cyanobacteria
kelp
Dinoflagellates have a cell wall made of plates composed of
cellulose
silica
lipids
protein
Dinoflagellates are important open-water primary producers in
temperate/cool water
tropical/warm water
polar/cold water
deep/salty water
Protozoans obtain energy from
photosynthesis
ingesting food particles
photosynthesis and ingesting food particles
chemosynthesis
Symbiotic bacteria that produce bioluminescence help deep sea animals
communicate
lure prey
blend in (camoflague)
all answers are correct
Red tides can be toxic because of a toxin released by these unicellular protists
diatoms
dinoflagellates
protozoans
all answers are correct
Forams and radiolarians have feet-like extensions to capture food called
tentacles
nematocysts
pseudopodia
spindles
What Kingdom do seaweeds (multicellular algae) belong?
Plantae
Protista
Animalia
Fungi
What do seaweeds such as giant kelp provide beyond being a food source (primary producer)?
they protect coral reefs
they take salt out of the water
they create a habitat for many organisms
What does chlorophyta mean?
green plant
brown plant
red plant
What accessory pigment makes brown algae usually "yellowish-brown" and allows them to absorb the green wavelength of light in coastal waters?
chlorophyll
fucoxanthin
phycobilins
What accessory pigments do red algae have that make them red/purple and allow some species to live in really deep water?
chlorophyll
fucoxanthin
phycobilins
This gelatinous type of chemical from seaweeds is used in food processing and the manufacturing of many goods:
chlorophyll
carotenoid
phycobilin
phycocolloid
Flowering plants have
true leaves
transport tissue (xylem and phloem)
roots
all answers are correct
Seagrasses are important because:
they provide habitat for many animals
they can protect coral reefs from sediment
they are nurseries for juvenile fish
all answers are correct
Cordgrasses can survive in salt marshes because
they have glands to excrete excess salt
they have thick roots
they can chemosynthesis sulfides in the sediment
Mangroves trees produce
broad-shaped seedlings to drift away on currents
pencil-shaped seedlings to stick in the mud
parachute-seedlings to drift on coastal winds
