Morphology of Flowering Plants
- It is the branch of biology which deals with the study of external structures of plants and animals.
- A plant consists of a root system (underground part) and a shoot system (above the ground parts).
- Roots are the parts of the root system; and stem, leaves, flowers, and fruits are parts of the shoot system.
- It helps in anchoring plant and absorbing water and minerals.
- Developed from the radicle part of a cotyledon
- It consists of a region of meristematic activity covered by a root cap, a region of elongation, and a region of maturation having root hairs.
- Types of roots system:
1. Tap root system
- It consists of a primary root that grows deep inside the soil.
- It also bears lateral roots referred to as secondary and tertiary roots.
- Example- Dicotyledons (mustard)
- 2.Fibrous root system
- Primary root is short-lived and is replaced by a large number of secondary roots.
- Example- Monocotyledons (wheat)
- 3. Adventitious roots
- Roots arise from parts other than the radicle.
