Algae

Front 1

how do algae differ from plants?
3 ways

Back 1

algae have no true roots, stems, leaves
-algae lack tissue differentiation
-reproductive structures form gametes in single-celled gametangia or gamete chambers

Front 2

unicellular algae-

Back 2

single cell; aquatic organisms that compose the photoplankton a population or photosynthetic organsims that form food chain

Front 3

colonial algae

Back 3

structure: grooves of cells acting in a coordinated manner; move feed and reproduce efficiently

Front 4

filamentous algae-

Back 4

slender, rod shaped thallus composed of rows of cells joined end to end
grows towards sunlight @ waters surface

Front 5

multicellular algae-

Back 5

zoospore-

Back 7

flagellated spore that develops within the parental cell

Front 8

zygospore-

Back 8

protective structure that results when the wall surrounding ta zygote thickens

Front 9

antheridium-

Back 9

a reproductive structure that produces sperm

Front 10

oogonium

Back 10

unicellular gametangium that produces eggs

Front 11

alternation of generations-

Back 11

sex life cycle in plants and algae involving 2 or more phases

Front 12

Gametophyte-

Back 12
