Study Notes
Plant Shoot System
- Consists of stems, leaves, and flowers.
- Responsible for the growth and development of the plant above ground.
Biennial Plant Life Cycle
- Life cycle lasts for two growing seasons.
- Typically, in the first year, the plant establishes roots and vegetative growth; in the second year, it flowers and produces seeds.
Stem Origin in Plants
- Stems originate from the embryonic shoot of the plant.
- The shoot apical meristem is critical for stem development as it facilitates growth upwards.
Stem Functions
- Supports leaves and reproductive structures, ensuring they are positioned for optimal sunlight.
- Transports water, nutrients, and food between roots and leaves.
Classification of Annual Plants
- Plants that complete their life cycle in one growing season are classified as annuals.
- They germinate, grow, flower, produce seeds, and die all within the same year.
