Study Notes
Plant Tissue Systems
- The dermal tissue system protects the plant from water loss, regulates gas exchange, and provides mechanical support.
Plant Transport System
- The vascular tissue system is responsible for transporting water, nutrients, and sugars throughout the plant.
Stomata Function
- Stomata contribute to plant physiology by regulating gas exchange, allowing for CO2 uptake and O2 release, and controlling water loss through transpiration.
Root Functions
- The root system is responsible for anchoring the plant, absorbing water and ions, conducting water to shoots, and storing energy for future use.
Modified Roots
- Modified roots like pneumatophores play a key role in plants growing in aquatic environments, allowing for gas exchange and oxygen uptake from the air.
Plant Morphology
- The morphology of roots and leaves contributes to plant growth by increasing the surface area for absorption and uptake of water and nutrients, and facilitating photosynthesis.
Primary Growth
- Primary growth in plants occurs through the activity of apical meristems, resulting in an increase in plant length.
Water Transport
- Water transport in plants is influenced by factors such as transpiration, root pressure, and capillary action.
Translocation
- Translocation in plants refers to the movement of sugars and other organic compounds from sources to sinks, typically from leaves to roots, fruits, and flowers.
Muscle Tissue
- There is no smooth muscle tissue found in the gastrointestinal tract of animals.
Epithelial Tissue
- Epithelial tissue forms the lining of organs and glands, and is involved in functions such as absorption, secretion, and protection.
Homeostasis
- Homeostasis in animals involves the regulation of internal environment, but it is not a mechanism that can be used to control external environmental factors.

Description
Explore the importance of surface area to volume relationships in plants, focusing on roots' absorption of water and nutrients, as well as leaves' absorption of light. Understand how the morphology of roots and leaves contributes to higher absorption efficiency. Learn about the various functions of root systems, such as anchoring the plant, water absorption, and conducting water to shoots. Discover different types of modified roots like anchor roots, prop roots, pneumatophores, and storage roots.
