Algae: Structure and Survival
Explore the fascinating biology of seaweeds and microalgae. Learn essential phycological terms and discover how these photosynthetic wonders harness light, manage nutrients, and reshape aquatic ecosystems.
Like Duolingo, but for Algae: Structure and Survival. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Deciphering the Algal Body and Algal Physiology in Action. It starts from scratch.

Key ideas in Algae: Structure and Survival
- Seaweeds lack internal veins and plumbing systems
- The entire plant-like algal body is called a thallus
- Almost every cell in the algal body absorbs moisture and nutrients directly from the surrounding water
- Holdfasts serve strictly as mechanical anchors to keep algae from drifting away
- Holdfasts do not absorb water or minerals like true plant roots do
- Nutrient uptake occurs directly through exposed tissue surfaces
- A stipe acts like a flexible stem that bends with ocean waves without snapping
- Blades act like leaves, offering wide surface area to catch sunlight
- A holdfast grips the substrate
- Kelp needs sunlight near the water surface to survive
- Gas-filled air bladders provide the buoyancy needed to float blades upward
- These flotation bulbs are called pneumatocysts
- Seaweeds are traditionally grouped into red, brown, and green categories based on their visible color
- Each broad group's visible color comes from unique accessory pigment suites masking or accentuating chlorophyll
- Scientific names directly reflect color terms: Chlorophyta means green, Phaeophyta means dusky brown, and Rhodophyta means red
- Water filters out long, low-energy red wavelengths within the top few meters of the surface
