Study Notes
- Plants make their own food through photosynthesis, where they use sunlight to produce glucose, their main source of nutrition for growth and function.
- Roots of plants absorb water from the soil, which travels through xylem tissue to the leaves, while leaves take in carbon dioxide from the air through stomata.
- Photosynthesis occurs in cells like Palisade and spongy cells in the leaves, which contain chloroplasts with chlorophyll, the green pigment that traps sunlight energy for chemical energy.
- Chlorophyll splits water molecules into hydrogen and oxygen atoms, using the chemical energy to create glucose from hydrogen and carbon dioxide, providing food for the plant's growth.
- Plants release oxygen as a byproduct of photosynthesis, which is essential for humans as we inhale oxygen and exhale carbon dioxide, showing the important partnership between plants and humans.
