1. Taproots: A type of root modification in which the main root grows deep into the soil. This helps the plant to reach water and nutrients deep in the ground and stabilize the plant in harsh weather conditions.
2. Adventitious roots: These are roots that grow from above ground parts of the plant such as stems or leaves. They help plants in waterlogged environments by providing additional support to the plant.
3. Buttress roots: These are thick, above-ground roots that provide additional support to the plant in areas with low soil fertility and erosion-prone soils. The roots form a strong network around the base of the plant.
4. Storage roots: These roots store water and nutrients for the plant to use during periods of drought or if the soil is poor in nutrients. Examples of plants with storage roots are sweet potatoes and carrots.
5. Prop roots: This modification involves roots growing from the stem of the plant and down into the ground for additional support. It is commonly seen in plants growing in areas with high winds and strong currents.
6. Pneumatophores: These are aerial roots that grow from the waterlogged soil in mangrove swamps. They help the plant to obtain oxygen from the air because the roots are immersed in water.
7. Contractile roots: These roots are modified to contract and pull the plant deeper into the soil. This happens when the soil is dry or when the plant is lifted above ground. The roots help the plant to anchor itself and reach deeper into the soil for water and nutrients.
Name all root modifications that allow plants to adapt in limiting and damaging conditions. Name each modification and it’s adaptive function
