1. Roots: Roots are the underground anchors of a plant. They perform several important functions:
* Anchoring: Roots hold the plant firmly in the ground, preventing it from being blown over by wind or washed away by rain.
* Water and Nutrient Absorption: Roots absorb water and dissolved minerals from the soil, which are essential for the plant's growth and survival.
* Storage: Some plants, like carrots and beets, have specialized roots that store food reserves for later use.
2. Cuticle: The cuticle is a waxy, waterproof layer that covers the leaves and stems of many plants. It plays a crucial role in preventing water loss:
* Reducing Transpiration: The cuticle acts as a barrier, slowing down the rate of water evaporation from the plant's surface, especially in dry environments.
* Protection from Pathogens: The cuticle also helps protect the plant from harmful bacteria, fungi, and other pathogens that could cause disease.
These structures demonstrate how plants have adapted to the challenges of living on land, where water is scarce and the environment can be harsh.
