Study Notes
Meristematic Tissue
- Composed of embryonic tissues, essential for plant growth.
Apical Meristem
- Responsible for primary growth, allowing plants to lengthen.
- Located at the tips of roots and shoots (blue areas).
Lateral Meristem
- Facilitates secondary growth, contributing to the increase in thickness of stems and roots.
- Found along the sides of stems and roots (red areas).
Permanent Tissues
- Consist of specialized cells that have ceased dividing.
- Form various plant structures such as leaves, stems, and roots.
- Play key roles in support, transport, and storage.
Types of Permanent Tissues
- Divided into surface, fundamental, and vascular tissues.
Surface Tissues
- Serve to cover and protect the outer surfaces of plant organs.
Fundamental Tissues
- Make up the bulk of the plant; fill the internal spaces of plant organs.
Vascular Tissues
- Complex conducting tissues that facilitate the movement of fluids throughout plants.
- Comprise two main types: xylem and phloem.
Xylem
- Primarily made up of dead cells when mature.
- Responsible for transporting water and dissolved minerals from roots to leaves.
Phloem
- Consists of living cells that transport food, primarily sugars from leaves to other plant parts.
Leaves
- Main organs for photosynthesis, converting sunlight into energy.
Stem
- Elevated structure supporting leaves.
- Conducts water and nutrients between roots and leaves.
- Produces new tissues for growth.
Summary
- Plants feature two primary types of tissues: meristematic (for growth) and permanent (for specialized functions).
- Meristematic tissues give rise to permanent tissues, which differentiate into specialized cells performing functions like photosynthesis and nutrient transport.
