6. ANATOMY OF FLOWERING PLANTS
The anatomy of flowering plants is structured into various tissues that organize into three main systems: epidermal, ground, and vascular. These systems are crucial for supporting plant functions such as water and nutrient transport, and photosynthesis. Dicotyledonous and monocotyledonous plants display distinct internal anatomical characteristics influenced by their structure and growth processes.

What we have learnt
- Plant anatomy involves studying the internal structure and functional organization of higher plants.
- There are three types of tissue systems in plants: epidermal, ground, and vascular.
- Monocots and dicots exhibit differences in their vascular bundle arrangements, influencing their growth and development.
Key Concepts
- -- Epidermal Tissue System
- The outermost tissue layer of the plant, consisting of epidermal cells, stomata, and trichomes, playing a crucial role in protection and water regulation.
- -- Ground Tissue System
- Comprises the bulk of the plant's tissue, including simple tissues like parenchyma and sclerenchyma, responsible for various functions such as storage and support.
- -- Vascular Tissue System
- Includes xylem and phloem, which facilitate the transport of water, minerals, and nutrients throughout the plant.
- -- Monocotyledonous Plants
- Plants with one seed leaf, characterized by scattered vascular bundles and no cambium in their stems.
- -- Dicotyledonous Plants
- Plants with two seed leaves, characterized by ring-shaped vascular bundles with cambium presence, allowing for secondary growth.
