Mississippi Science BOT.1.1
The Standard
- BOT.1
- Students will investigate the morphology, anatomy, and physiology of plants.
Analyze models (3-D, paper, and/or computer-based) to distinguish the basic morphology of the plant kingdom, with attention to structures and their related functions. Use cladograms or phylogenetic trees to identify evolutionary features that distinguish the plant kingdom from other kingdoms.

What This Standard Means
What Students Need to Do
- Use plant and cell models to name parts and explain their jobs. Trace traits on a cladogram to compare mosses, ferns, seed plants, green algae, and fungi.
What Mastery Looks Like
- Students identify chloroplasts as sites of photosynthesis and cellulose cell walls as support. They explain the jobs of roots, stems, and leaves where those parts occur. On a cladogram, they place protected embryos before mosses and seeds after ferns branch off.
Common Misconceptions
- Students may call moss rhizoids roots or assume every plant makes seeds and flowers. They may read a cladogram as a ladder, or think chloroplasts alone separate land plants from green algae.
How to Assess It
- Give students sketches of a moss and sunflower beside a cladogram of green algae, mosses, ferns, and sunflowers. Ask them to label one structure and its job on each plant, then mark where protected embryos first appear.
Lesson moves
Ways to Teach It
Build paper models of moss and bean plants; label rhizoids or roots, photosynthetic parts, and reproductive structures with their jobs.
Show a cladogram of fungi, green algae, mosses, ferns, and sunflowers; ask why mosses and sunflowers share embryos but not seeds.
Play a trait-card sort: place cuticle, vascular tissue, seeds, and flowers on the first matching branch of a plant cladogram.
Compare a pinecone and a cut apple, then identify where seeds form and why only the apple has fruit.
