(Marque todo lo que se aplica sobre las Diatoms)

Dinoflagellates are similar to plants because...

(Dinoflagellates son similares a las plantas porque...)

• They don't move or eat other organisms.

• They photosynthesize and have similar cell walls.

• They reproduce sexually.

• They have no similarities, actually.

Would you rather be reborn as a Diatom or a Dinoflagellate? (Prefieres renacer como una Diatom o Dinoflagellate?)

• Diatom, because I like to float and take it easy.

• Diatom, because I want to support whole ecosystems!

• Dinoflagellate, because I want to move around.

• Dinoflagellate, because I want to glow.

Why did diatoms evolve to release oil inside themselves?

(¿Por qué evolucionaron las diatoms para liberar aceite en su interior?)

• Oil makes them darker, letting them hide.

• Oil makes them taste bad to predators.

• Oil helps them float toward the surface.

• Oil is a byproduct of respiration.

(¿Por qué son importantes diatoms y dinoflagellates en un ecosistema?)

• They provide much of the energy for other organisms.

• They keep the water perfectly clear.

• They absorb toxins and chemicals, so that other animals don't have to.

• They're not actually very important.

• Have an spot that detects light.

• Have two flagellum that they use to move.

• Reproduce mostly sexually.

• Have cell walls made of cellulose.

A large "bloom" of diatoms in the water is called a _____.

(Una gran "floración" de diatoms en el agua se llama _____).

What's are some similarities between diatoms and dinoflagellates?

(¿Cuáles son algunas similitudes entre las diatoms y los dinoflagellates?)

• Both are microscopic.

• Both are usually beneficial, but can be harmful during "blooms."

• Both are heterotrophic.

• Both have evolved ways to move toward light to photosynthesize.

• Mr. Hellmer loves both deeply.

Why do you think dinoflagellates evolved two flagella instead of one?

(¿Por qué crees que los dinoflagellates desarrollaron dos flagelos en lugar de uno?)

• So they can move twice as fast.

• In case one breaks.

• So that they can turn and move more easily.

• Two is always better than one.
