Study Notes
Epidermis and Stomata
- The main function of the dermal tissue or epidermis in herbaceous plants is to protect the plant from water loss and pathogens.
- Stomata in the epidermis of leaves allow for gas exchange, specifically CO2 uptake and O2 release, during photosynthesis.
- Guard cells in the epidermis of leaves regulate stomatal opening and closing, controlling gas exchange and water loss.
Photosynthesis and Mesophyll
- Photosynthesis primarily occurs in the mesophyll tissue of a leaf, specifically in the chloroplasts.
- The main function of the ground tissue or mesophyll in a plant leaf is to carry out photosynthesis.
- Palisade tissue within the mesophyll is specialized for photosynthesis, with tightly packed chloroplasts to maximize light absorption.
Xylem and Phloem
- Xylem tissue is responsible for the transfer of water and dissolved minerals up from the roots to the stem and leaves.
- Phloem tissue is responsible for moving sucrose and other dissolved sugars throughout the plant.
- Root pressure is responsible for pushing water up the xylem from the roots to the leaves.
Transportation and Pressure
- Cohesion tension, where water molecules pull on adjacent molecules, aids in the transport of water in plants.
- Transpiration pull, a type of pressure, forces fluids up the xylem from higher pressure in the roots towards lower pressure in the leaves.
Chloroplasts and Spongy Tissue
- Chloroplasts are found in the largest amount in the mesophyll tissue of a leaf.
- Spongy tissue is located in the interior of the leaf, allowing for gas exchange and photosynthesis.
Phloem Functions
- Phloem takes sucrose and other dissolved sugars from the leaves to be transported throughout the plant.
