Question

one of the species that are responsible for harmful algal blooms are *
diatoms
angiosperms
symbiodinium
dinoflagellates

select all the following structures that angiosperms have. (there is three)
flowers
leaves
roots
stems

Explanation:

• First question: Dinoflagellates are known to cause harmful algal blooms. Diatoms are important in marine ecosystems but not typically associated with harmful blooms. Angiosperms are flowering plants (not algae). Symbiodinium is a genus within dinoflagellates but the more general term for the group causing harmful blooms is dinoflagellates.
• Second question: Angiosperms (flowering plants) have flowers (their reproductive structures), leaves (for photosynthesis), roots (for anchorage and water/nutrient uptake), and stems (for support and transport).

Answer:

• First question: Dinoflagellates
• Second question: Flowers, Leaves, Roots, Stems
