Target: match chloroplast and large vacuole functions to the photosynthetic leaf model, and avoid blanket claims about plants and animals. Prepare: Cards C/D and organelle jobs.
- Launch · 2 min. Show the fictional Leaf mesophyll inventory. Ask which listed structure connects to photosynthesis.
- Model · 4 min. Match chloroplast to photosynthesis and large central vacuole to water balance in many plant cells. Mitochondria are also on this plant card; plants do not lack them.
- Guided reading · 5 min. Contrast the Human intestinal lining model: no chloroplast appears in its complete comparison inventory, but nucleus, mitochondria and ribosomes do. Discuss why a root or other nonphotosynthetic plant cell need not have chloroplasts.
- Practice route · 7 min. Choose Day 4 route; write a corrected caption for the two card inventories using one plant-specific teaching example and two shared eukaryotic features.
- Audit · 4 min. Peer searches for “all plant cells” or “animals never have vacuoles” and narrows both claims.
- Exit · 3 min. “Do plant cells need mitochondria?” Key for these models: the photosynthetic leaf card has both chloroplasts and mitochondria; photosynthesis and respiration are different processes.
