Study Notes
Living Plants and Food Production
- Plants are classified as living organisms capable of making their own food through a process called photosynthesis.
- Green leaves are pivotal in food production for the plant.
Parts of a Leaf
- Stalk (Petiole): Connects the leaf to the stem, allowing attachment.
- Main Vein (Midrib): Central vein that runs through the middle of a leaf, providing support.
- Leaf Blade (Lamina): The flat, broad part of the leaf essential for capturing sunlight.
- Side Veins: Branch out from the main vein, responsible for transporting water, minerals, and food.
Functions of Leaves
- Leaves serve as the plant's food factories, creating vital nutrients.
- Facilitate breathing in plants through tiny openings known as stomata.
- Contribute to a plant’s overall shape and color.
Stomata
- Stomata (singular: stoma) are tiny pores located on the lower layer of leaves.
- They enable the exchange of gases, allowing carbon dioxide intake and oxygen release, along with excess water vapor.
Photosynthesis Process
- Photosynthesis is the process where green leaves synthesize food using carbon dioxide, water, sunlight, and chlorophyll.
- The term derives from "photo" (light) and "synthesis" (putting together).
Food Production Mechanism
- Roots absorb water and minerals from soil and transport them to leaves via the stem.
- Leaves intake carbon dioxide through stomata while capturing sunlight using chlorophyll.
- Sunlight energy assists in combining water and carbon dioxide, producing glucose, a simple sugar serving as plant food.
- During this process, oxygen is released back into the atmosphere through stomata.
