Answer: yes, seeds need water to grow. The seed in order to grow will go through various stages and it cannot happen without water.
Step-by-step explanation:
1. Germination: When a seed is exposed to water, it absorbs the moisture and swells up. This triggers a process called germination, where the seed starts to grow into a new plant.
2. Activation of enzymes: Water is essential for activating enzymes present in the seed. Enzymes are responsible for breaking down stored food in the seed into usable forms. Without water, these enzymes cannot function properly, and the seed will not be able to obtain the necessary nutrients for growth.
3. Transportation of nutrients: Water acts as a medium for transporting nutrients from the soil to the growing seedling. Through a process called osmosis, water moves into the seed, carrying along dissolved minerals and nutrients that are needed for growth.
4. Cell expansion: Water is vital for cell expansion and elongation. As the seed germinates and the root emerges, cells in the growing plant need water to increase in size and lengthen. This helps the plant establish a strong root system and enables it to take up water and nutrients from the soil.
5. Photosynthesis: Water is a key component in the process of photosynthesis, where plants convert sunlight into energy. During photosynthesis, water molecules are split, providing hydrogen atoms that are used in the production of glucose, the main source of energy for plants. Without water, photosynthesis cannot occur, hindering the growth of the plant.
In conclusion, seeds need water to grow because it triggers germination, activates enzymes, transports nutrients, enables cell expansion, and facilitates photosynthesis. Without water, the seed will not be able to sprout and develop into a healthy plant.
