🌱 Plants can be avascular or have vascular tissue for distributing water and nutrients.
⏳ Vascular tissue in plants, called xylem and phloem, developed around 400 million years ago.
🌿 Xylem and phloem are hollow tubes that transport water and nutrients in plants.
🌱 Xylem and phloem are vascular bundles in a leaf that transport water and nutrients to the plant.
🌿 The xylem and phloem have different structures and functions.
💦 The xylem is responsible for transporting water.
🌱 The xylem transports water and minerals from the roots to the rest of the plant.
🌿 The phloem distributes organic compounds produced in the leaves to different parts of the plant.
☀️ Photosynthesis allows the plant to create organic molecules from carbon dioxide, water, and sunlight.
Phloem allows the flow of water, minerals, and organic compounds in both directions within a plant.
Phloem is made up of live cells, while xylem is made up of dead cells.
A cross section of a leaf reveals the concentrated vascular tissue in the central part, surrounded by layers of epidermis cells and spongy parenchyma.
🌱 The xylem transports water and minerals from the roots to other parts of the plant.
🍃 The phloem transports organic molecules made in the photosynthetic parts of the plant to other parts as needed.
🌿 The xylem and phloem are located in the central region of a leaf and in the central part of a plant root respectively.
🌱 Phloem channels transport water and organic compounds.
