Study Notes
Plant Tissues
- Plant tissues are categorized as meristematic or permanent.
- Meristematic tissues are based on the "capacity to divide".
- Permanent tissues are based on the "capacity to not divide".
- Meristematic tissues are further categorized into primary and secondary.
- Primary meristems are further categorized into apical and intercalary.
- Secondary meristems are further categorized into lateral.
- Apical meristems are located at the tips of roots and shoots and increase the length of roots and stems.
- Intercalary meristems are located between the nodes and leaf blades of monocots and allow for rapid regrowth after herbivory.
- Lateral meristems are on the sides of stems and roots and increase stem and root diameter.
Apical Meristems
- Procambium is part of apical meristem and develops into vascular tissues (xylem and phloem).
Intercalary Meristems
- Intercalary meristems are a type of primary meristematic tissue.
- These tissues are located at the bases of nodes and leaf blades.
- They are important for growth in the length of monocot plants to recover from herbivory.
Lateral Meristems
- Lateral meristems cause secondary growth in plants in the dicot class.
- Secondary growth increases the diameter of stems and roots.
- Vascular cambium and cork cambium are types of lateral meristem.
Apical vs Intercalary vs Lateral Meristem
- Apical meristems are at the tips of the stems and roots and increase length.
- Intercalary meristems are between nodes of stems and the base of leaves and increase the length between nodes.
- Lateral meristems increase the diameter of stems and roots.
