Mississippi Science BOT.1.3

ScienceGrades 9–12Botany

The Standard

BOT.1: Students will investigate the morphology, anatomy, and physiology of plants.

Describe the relationship between the structure and purpose of plant organs (e.g., roots, stems, and leaves).

2026 Mississippi College- and Career-Readiness Standards for Science · Plant Morphology, Cell Structure, and Function

Teacher's field guide

What Students Need to Do: Students connect features of roots, stems, and leaves to the jobs they do. They explain how water moves through a plant and how broad leaves help it collect light.
What Mastery Looks Like: A student can explain how root hairs take in water, stem tubes carry it, and broad leaves catch light. They can predict why leaves wilt when roots are damaged.
Common Misconceptions: Some students think roots eat soil, rather than absorb water and dissolved minerals. Others think stems only hold plants upright or that leaves take in most of a plant's water from rain.
How to Assess It: Exit ticket: Sketch a root, stem, and leaf. Label one feature on each, explain its job, and predict what happens to the leaves if the stem is crushed.

Lesson moves

Give pairs a bean seedling and hand lens; have them sketch branching roots, the stem, and broad leaves and label each part's job.
Ask: Why do leaves spread out aboveground while roots branch underground? Have students answer using light and water.
Put root hairs, stem tubes, and broad leaf blades on cards; teams match each feature to absorption, transport, or light capture.
Show a cut flower; ask students why florists trim its stem before placing it in water.
