Seeds and Growing Plants Parts of a plant Function of plant parts Parts of a flower What are seeds? Parts of a seed – seed coat • Why do seeds have a seed coat? Why do seeds have a seed coat? Why are seeds so different? Shape Size Colour Texture Seed coat texture • Cactus seed under a powerful microscope Parts of a seed – Inside the seed Parts of a seed First leaves Epicotyle = stem What do seeds need to GERMINATE? Oxygen - Growth Sun - Energy for PHOTOSYNTHESIS Temperature – Cold? Hot? Warm? Water - Photosynthesis and growth GERMINATION What is germination? Steps: 1. Seed coat breaks 2. Radicle becomes ROOT 3. Hypocotyl and epicotyl become the STEM 4. First leaves grow = PHOTOSYNTHESIS First leaves PARTS OF A SEED - INSIDE Plants need NUTRIENTS Carbon Hydrogen Oxygen Soil nutrients Soil nutrients Nitrogen – Growth, photosynthesis Phosphorus – photosynthesis, flowering Potassium – build proteins, prevent disease Calcium – Strong cells Magnesium – Photosynthesis Sulfur - build proteins and produce food Soil quality - pH pH=7
