🌱Stems are organs composed of different tissue types and serve as the foundational element for plants.
💪Stems provide support for plants, allowing them to grow vertically and horizontally.
💧Stems have a vascular column that transports water and nutrients throughout the plant.
🍃Stems consist of nodes and internodes, with leaves attached to the nodes.
🌳Stems differ in structure between herbaceous and woody plants.
What are the main functions of plant stems?
—Plant stems provide support, transport water and nutrients, and protect against water loss and infections.
What is the difference between herbaceous and woody stems?
—Herbaceous stems do not grow much thicker over time, while woody stems grow taller and add girth each year.
What is the role of the vascular column in stems?
—The vascular column transports water and nutrients throughout the plant.
Why are leaves attached to nodes on stems?
—Leaves are attached to nodes on stems to allow for photosynthesis and gas exchange.
How do stems provide support for plants?
—Stems grow vertically, making plants taller, and horizontally, providing increased girth.
