A young plant's stem is green and actively photosynthesizing. As the plant matures, what transformation is most likely to occur in the stem?
A young plant's stem is green and actively photosynthesizing. As the plant matures, what transformation is most likely to occur in the stem?
- It will become woody and dark brown, reducing photosynthetic activity. (correct)
- It will begin to attract pollinators through vibrant color changes.
- It will remain green and continue photosynthesis indefinitely.
- It will develop specialized water-absorbing cells similar to root hairs.

Study Notes
- The stem is the ascending axis of a plant
- Stems bear branches, leaves, flowers, and fruits
- Stems originate from the plumule of a germinating seed's embryo
- Stems have nodes, where leaves are attached
- Internodes are the regions between two nodes on a stem
- Stems have buds that can be either terminal (at the tip) or axillary (in the leaf axil)
- Young stems are typically green, maturing into woody, dark brown structures
- Stems spread out branches to hold leaves, flowers, and fruits
- Stems transport water, minerals, and photosynthates (products of photosynthesis)
- Some stems store food
- Some stems provide support and protection to the plant
- Some stems facilitate vegetative propagation (asexual reproduction)
