Study Notes
- Plants have three basic organs: roots, stems, and leaves, composed of three kinds of tissues.
- Learning outcome: identify and describe plant organs, tissues, and cells for subsequent lessons.
- Roots anchor plants, absorb water and minerals, and store carbohydrates.
- Modified roots serve additional functions such as structural support, storage, and resource acquisition.
- Stems support leaves and reproductive shoots and distribute water, minerals, and photosynthates throughout the plant.
- Modified stems store carbohydrates and propagate plants asexually.
- Leaves are the main photosynthetic organ and have a diversity of shapes.
- Modified leaves serve various functions such as climbing, defense, storage, and reproduction.
- There are three tissue systems in plants: dermal, vascular, and ground.
- Dermal tissue functions in defense and water loss prevention through the epidermis or periderm.
- Vascular tissue transports water and minerals through xylem and organic nutrients through phloem.
