QUIZ 1 | MARINE ORGANISM CLASSIFICATION AND ADAPTATION

What adaptation helps Diatoms to adsorb more sunlight?

• A clear silica membrane that allows light to pass through

• Electromagnetism that attracts helpful UV rays

• Floating mechanisms that keep them close to the surface

• Attaching themselves to plants and stealing their light

What adaptation helps Algae be exposed to maximum sunlight?

• Blades which adsorb sunlight and water to create energy

• Holdfasts which anchor algae to rocks and substrates

• Pneumatocysts which hold air and cause algae to float

• Rhodophyta which is the name for the pigment of red algae

Why do UNICELLULAR marine organisms need sunlight?

• To achieve photosynthesis

• To glow and avoid predators

• To maintain direction in migration

• To stay warm in deep ocean waters

Why do many beach plants have waxy leaves?
