Study Notes
Plant Habit
- Plant habit refers to the general growth form of a plant
- Herbaceous (herb) plants have no woody tissue
- Examples of herbaceous plants include beans and irises
Leaf Arrangement
- Opposite clusters of leaves can give the appearance of a whorl or verticel due to overcrowding
- Verticels are arranged in a racemose manner
Epidermal Cells
- Cutine and other waxy polymers are deposited on the free surface of epidermal cells, forming a structure called cuticle
Cell Wall Composition
- Pectins have more links with cellulose than hemicellulose with cellulose
- Pectins help to hydrate the primary cell wall
Tissue Development
- Leaf primordia arise from the eumeristem
- Procambium and cortical ground tissue also arise from this region
