Plant tissues Flashcards
- Derived from shoot and root apical meristems
- Composed of primary tissues
- Constitutes the herbaceous parts of a plant
Primary Plant Body (Herbaceous Body)
Plant that never becomes woody nor covered with bark; often lives for < 1 year; consists only of a primary plant body
Herb
- Derived from meristems other than apical meristems
- Composed of secondary tissues: wood and bark
- Constitutes the woody, bark-covered parts of a plant
Secondary Plant Body (Woody Body)
consists only of primary tissues.
Has primary tissues at its root and tips
Secondary tissues arise inside the primary tissues
Woody plant
group of cells that perform specific function
Tissues
Classification based on stage of development
Embryonic / meristematic
Permanent
▪ Simple (only one type of cell)
▪ Complex (different types of cells group together into tissue)
Based on composition
tissues where the cells are in themitotic state
Meristematic
Actively dividing development
meristematic
– cells are stable, no longer dividing
- It is differentiated into 2 types
Permanent
Types of permanents
Simple permanent tissue
Complex permanent tissue
Types of Simple Permanent Tissue
Parenchyma Tissue
Collenchyma Tissue
Sclerenchyma Tissue
Types of complex Permanent Tissue
▪ Xylem (transport water)
▪ Phloem (transport food)
- composed of one type of cells
- differentiates into dermal or protective and ground or fundamental
- Classified based on the nature of cell wall
Simple permanent tissue
- composed of different kinds of cells but perform similar function
Complex permanent tissue
