Plant Parts Notes Basic Parts of a plant • Roots • Stem • Leaves • Flower • Fruit • Seed Roots • Anchor and support plants • Absorb and conduct water and minerals • Store products of photosynthesis • Winter survival of perennials (carbohydrates, sugars, proteins) Stem • Framework for leaves, flowers and seeds • Continuation of vascular system carrying water and minerals from the soil, and sugars manufactured in leaves throughout the plant. • Green stems also manufacture food (photosynthesis). • Food storage Leaves • To compete for light for photosynthesis, i.e., the manufacture of sugars • Evapotranspiration from the leaves is what moves water and nutrients up from the roots. • Small openings on the leaf, known as stomata, regulate moisture and gas exchange (water and carbon dioxide) and temperature (cooling effect as water vapor escapes through stomata). Flower • Reproduction, beginning with pollination and fertilization. • Advertisement and rewards to lure a pollinator. Fruit • Reproduction Seed • Propagation
