Unless a plant is specifically adapted to stand in water (example: mangrove), it can besubject to over watering and be damaged or even die.

Normally the soil consists of sand or stone particles, organic components (such as hums or decayed vegetable material) and open air pore spaces. The nature of the soil is determined by the type and size of the mixture of the components. For example a clay soil at one extreme and a sandy soil at the other extreme.

From this mixture of soil components the plant is able to absorb nutrients, water and importantly oxygen.

When the soil becomes waterlogged or is over watered, the empty spaces containing air (and oxygen) are filled with water, and the oxygen forced from the soil.

As there is no oxygen in the soil, the root system becomes damaged (as plant cells required oxygen to metabolise). The root cells begin to break down and decompose. As Osmosis is the primary mechanism through which water, nutrients and oxygen are absorbed into the plant cannot occur (as the root cell membranes have become damaged or no longer exist) food, oxygen and water can no longer be taken up by the plant. In reality reverse osmosis occurs and plant nutrients begin to move from the damaged plant into the soil. This results in the characteristic yellowing of the basal leaves of the plant if it is over watered. The lower leaves are affected first as they are closer to the soil.

If the water logging of the soil is only for a short period the plant may be damaged, but may be able to recover, if the water logging is over a long period of time the plant will normally die.

As mentioned before certain plants are able to stand in water (such as mangroves), but these normally rely on aerial roots to provide oxygen to the plant.

What happens when plants transpire too much water?

When plants transpire too much water, they can become dehydrated and wilt. This can lead to stunted growth, reduced photosynthesis, and even death in severe cases.


What do you think would happen if there is too much water or sunlight?

If there is too much water, it can lead to waterlogging, root rot, and nutrient leaching in plants, which can ultimately cause plant stress or death. Similarly, excessive sunlight can lead to sunburn, leaf scorch, or wilting in plants due to increased transpiration and dehydration. Both scenarios can negatively impact plant health and growth.


What would happen if plant get too much water?

When a plant loses too much water the stomata close and oxygen and other substances cannot enter or leave the plant. The cells themselves will become plasmolyzed, whereby the cell membrane pulls away from the cell wall.


Does sunlight affects plans growth or does it needmore water?

Plants need sunlight and water to grow. It will die without water, and it will die without sunlight, it is just a matter of time. Different plants need different amounts of water and sunlight. What is not enough water for a rose may be too much water for a cactus. Likewise, what is not enough sunlight for a rose, may be too much sunlight for a rhododendrum. A plant with too little sunlight will not grow to it´s full height, and a plant with too little water will not grow to it´s full height either.


Will salt harm your plants?

Yes, too much salt can harm plants by drawing water out of their roots through osmosis. This can lead to dehydration and nutrient imbalances. It's important to monitor salt levels in soil to prevent damage to plants.
