What to know Roots anchor a plant and absorb water and nutrients. Stems support leaves and flowers. Stem tissues transport water and nutrients through the plant. 🔎 Think like a scientist Colored water moving up a celery stem can make the transport pathway visible.

Leaves, Flowers, and Seeds Learning goal: Connect plant structures to food production and reproduction.
What to know Leaves use sunlight, air, and water to help the plant make food. Flowers help many plants reproduce. Seeds can grow into new plants when conditions are suitable. 🔎 Think like a scientist A leaf captures light while roots supply water; these parts work together rather than acting alone.

What to know Stems commonly grow toward light. Roots commonly grow downward in response to gravity. A plant response can be tested with repeated observations over time. 🔎 Think like a scientist Turn a potted seedling sideways and record changes: roots tend downward while the stem bends upward and toward light.

What to know Temperature can affect growth and water loss. Compare similar plants while changing one condition. Use records rather than a single glance to identify a response. 🔎 Think like a scientist Measure matching plants kept at safe, different temperatures while keeping water, soil, and light alike.
