Roots
Plants take in water and nutrients such as nitrogen, phosphorus, and potassium through their roots. These essential substances are absorbed by the plant to support growth and development.
Plants take in water, minerals, and sunlight from their surroundings for photosynthesis. They also absorb carbon dioxide from the air.
Water and minerals
The rainwater contains minerals from the clouds, walls of rainwater tanks etc, thy just do. But water from a tap (unless bore water) Has no minerals in them and is clean and has no minerals.
Roots of plants absorb water and minerals from the soil through a process called osmosis. This allows plants to take up essential nutrients needed for growth and function. Water and minerals are then transported through the plant's vascular system to different parts of the plant.
Plants take in minerals through their roots.
To take minerals from the soil.
plant take in 400ml of water in a day.
Most plants cannot grow in saltwater because the high concentration of salt can dehydrate the plant and inhibit its ability to take up water. On the other hand, distilled water lacks essential minerals that plants need for growth, so they would also struggle to thrive in distilled water. Plants typically grow best in fresh water that contains a balanced amount of nutrients and minerals.
Ocean plants, like seaweed and phytoplankton, obtain nutrition through a process called photosynthesis. They use sunlight, carbon dioxide dissolved in water, and nutrients present in the seawater to produce energy. Additionally, some ocean plants can absorb nutrients directly from the water around them.
Soil and water help a plant grow because when the roots take up the water from the soil,some of it's minerals have dissolved in the water giving the plant nutrients. Water also helps the plants make food using the process photosynthesis.
