Anatomy of Flowering Plants Cheat Sheet

Key Definitions

• Angiosperms: Flowering plants that produce seeds enclosed within a fruit. ✅

• Stamen: Male reproductive part of a flower, consisting of anther and filament. ✅

• Pistil: Female reproductive part of a flower, consisting of stigma, style, and ovary. ✅

• Photosynthesis: Process by which plants convert light energy into chemical energy (glucose). ✅

Important Concepts

Flower Structure

• Complete Flower: Contains all four whorls (sepals, petals, stamens, pistils). ✅

• Incomplete Flower: Lacks one or more whorls. ✅

Plant Tissues

• Meristematic Tissue: Responsible for growth (apical, lateral, and intercalary). ✅

• Permanent Tissue: Differentiated and specialized for specific functions (simple and complex). ✅

Plant Functions

• Transpiration: Loss of water vapor from plant surfaces, mainly through stomata. ✅

• Pollination: Transfer of pollen from anther to stigma, can be biotic (insects) or abiotic (wind). ✅

Key Formulas

• CO2: Carbon dioxide

• H2O: Water

• C6H12O6: Glucose

• O2: Oxygen

Common Mistakes to Avoid

Common Mistake: Confusing stamen with pistil; remember, stamen is male, pistil is female.

Memory Tricks

Tip: "SPLASH" — Sepals, Petals, L stamens, Anthers, Stigma, Hybrids (for flower parts).
