Compare and contrast the functions of a land plant’s root and shoot systems.

Step 1 of 2

Shoot System:

The shoot system of a land plant consists of stems, leaves, buds, flowers, and fruits. Stems serve as the framework for upright growth, supporting and positioning leaves and flowers for optimal light exposure and pollination. Leaves are the primary photosynthetic organs that increase the plant's surface area, allowing for greater sunlight capture and facilitating the production of carbohydrates through photosynthesis. Buds are undeveloped or dormant shoots that have the potential to extend the shoot system or give rise to new branching shoots. Flowers and fruits are reproductive structures of flowering plants involved in the production of seeds and the process of sexual reproduction. Additionally, certain parts of the shoot system can store carbohydrates synthesized during photosynthesis, providing a reserve of energy for future growth and development.

Root System:

The root system of a land plant typically grows below the ground. Its main functions are anchoring the plant in the soil and absorbing water and dissolved minerals from the soil. Roots also play a role in structurally supporting the plant's aboveground parts, especially in larger and more complex plants. Through their extensive network of roots, plants can access water and nutrients necessary for growth and survival. The root system may also store carbohydrates, similar to certain parts of the shoot system, providing energy for the plant's metabolic processes.
