Why do plants and animals need water ? need simple answer for grade 6 please.
Answers
Answer:
Plants:
Plants need enough hydration to carry out photosynthesis. They get the water they need from the soil through their roots. The water in plants carries nutrients to other parts of the plant. Some plants such as the water lily need a lot of water, while desert cacti can go for months with outwater. Water keeps the plant firm and upright (turgid). They go flaccid when they go without water and soon, they die.
Some plants such as seaweed and algae absorb carbon dioxide dissolved in water.
Animals:
Animals also need water to carry out cell activity. Some animals drink water regularly to keep hydrated, digest food and build body fluids. Some fishes need saltwater and others need fresh water. Many kinds of fish such as clams and trout get oxygen from water.
Some animals have water as their habitat. Other such as frogs and turtle need water to lay eggs and reproduce. The anaconda snakes, together with many reptiles live in water. Freshwater often carries lots of dissolved nutrients that aquatic organisms depend on. Without water, they will not survive.
Explanation:
Plants: Water is an essential nutrient for plants and comprises up to 95% of a plant's tissue. It is required for a seed to sprout, and as the plant grows, water carries nutrients throughout the plant.
Animals: Animals need fresh water for their bodies to function. They gain water not only through the action of drinking but also from the food they eat. Water is vital for bodily functions such as regulation of temperature, nutrient uptake, removing wastes, body weight, and health.
