Key ideas in Phycology: The World of Algae
- Land plants need roots, veins, and stems to draw water up from the soil and distribute it through dry air
- Submerged algae absorb water, dissolved gases, and minerals directly through virtually all of their external surface cells
- Because aquatic algae are bathed in liquid, they have no need for internal vascular plumbing
- Giant kelp is a macroalga that relies on flexible tissues, not rigid woody support
- Small, gas-filled bladders along the kelp float its fronds toward sunlight at the ocean surface
- Water's natural buoyancy supports the alga's weight instead of a stiff trunk
- Single-celled microalgae like Chlamydomonas are microscopic drifters invisible to the naked eye individually
- Medium macroalgae like sea lettuce form multi-cellular leafy sheets a few inches to a foot across
- Giant kelp can grow into towering marine seaweeds spanning well over one hundred feet
- Certain microalgae live entirely on land rather than in ponds or oceans
- Terrestrial algae survive dry periods by going dormant, then revive when wetted by morning dew, fog, or rain
- Common sightings include thin green powdery stains on tree bark, stone walkways, and bricks
- Land plants inherited their characteristic green pigments directly from green algal ancestors
- All land plants descended from ancient freshwater green algae that adapted to living above water
- While land plants evolved complex tissues to handle dry land, their underlying photosynthetic machinery remains shared with green algae
- Seaweeds are categorized into three major groups: green, brown, and red
