The Five Divisions of Plantae
From algae to flowering plants.
Sort each plant or feature into its division.
Sorted 0/10
All items sorted — check each bin.
Free play — sort every item into the bin it belongs in; each correct drop tells you why. Switch to when you're ready to test yourself.
Read the divisions as a story of escaping water: no vascular tissue → no vascular tissue → vascular but spores → seeds → seeds inside fruits.
What this lesson covers
Challenges to clear
- Fill the Gymnospermae bin correctly.
- Sort every item.
- Fill the Pteridophyta box — the first plants with vascular tissue, still tied to water.
The task
Sort each plant or feature into its division.
What this lesson covers
- Thallophyta — Algae: Spirogyra and Ulothrix (Simple algae with no true root, stem or leaf.); Body is a thallus with no vascular tissue (The simplest plant body — often just a filament or sheet.)
- Bryophyta — Amphibians of the plant world: Moss and Marchantia (They need water for the sperm to swim to the egg.); Anchored by rhizoids; still no true vascular tissue (Which is why they stay small and live in damp places.)
- Pteridophyta — Ferns: Ferns and horsetails (The first plants with proper xylem and phloem.); First plants with true vascular tissue, but they reproduce by spores (Vascular tissue let them grow tall; spores still tie them to moisture.)
- Gymnospermae — Naked seeds: Pine, cycas and deodar (They bear cones, not flowers or fruits.); Seeds are borne exposed, not enclosed in a fruit (Gymno- means naked — there is no ovary to become a fruit.)
- Angiospermae — Flowering plants: Mango, rice and hibiscus (The largest and most successful group of plants.); Seeds enclosed in a fruit, formed from the ovary (Angio- means vessel — the seed is protected inside a fruit.)
Hint
Read the divisions as a story of escaping water: no vascular tissue → no vascular tissue → vascular but spores → seeds → seeds inside fruits.
