Explain why different parts of a plant need water. Roots need water Leaves need water Stem needs water Flowers need water Word bank: Support, anchor in the ground, make food, wilt.
Answer (1)
Plants need water for several important reasons, and different parts of a plant use water in different ways:
Roots :
Anchor in the ground : Roots absorb water from the soil, which helps anchor the plant securely in the ground by providing it with the necessary moisture to maintain soil contact.
Stem :
Support : Water contributes to turgor pressure, which is the pressure of the cell contents against the cell wall. This pressure helps the stem stay strong and upright, providing structural support to the plant.
Leaves :
Make food : Water is crucial for photosynthesis, the process by which plants make their food. During photosynthesis, water and carbon dioxide are converted into glucose and oxygen with the aid of sunlight.
Flowers :
Prevent wilting : Flowers need water to maintain their structure and prevent wilting. Water helps keep the petals firm and open, allowing the flower to attract pollinators.
In summary, water helps in maintaining plant structure, supporting growth, providing nutrients, and facilitating photosynthesis. It is essential for various physiological processes that keep the plant healthy and functioning.
