They get their water from the water in the soil! The roots carry it up to the leaves so the leaves can convert it into food.
a cactus holds water the most
It will most likely grow.
plant competitions is when a plant competes with another plant over who is tallest, who has the most water.
The roots of a plant typically absorb the most water from the soil. Water is taken up by the root hairs and transported throughout the plant to support various physiological processes. Transport tissues like xylem help move water from the roots to the rest of the plant.
The water is all the same and will keep the plant alive the additives are what matter most.
Depends on what you do with the water. If it is boiling when you pour it over the plant it will most likely scald and kill it. If it is boiling and you water the plant with it, you will damage the roots and the plant will die. However, if you wait until it cools and then water the plant with it there will be little change to the plant.
The roots
The most important features for a desert plant would be the ability to collect and store water and the ability to reduce water loss .
Most of the water in plants is lost through a process called transpiration, which is the evaporation of water from the plant's leaves through small pores called stomata. This loss of water helps to maintain the plant's internal water pressure and transport nutrients throughout the plant.
most of it (98%) will go through the plant the rest will be used in photosynthesis
Water and sunlight
Unless you plant is one that is adapted to brackish water or a seaweed, salt water will kill it. Sugar in the water will also kill most plant roots (though a very small quantity will help cut flowers last longer). Conversely, without water your plant will eventually die, so the answer is that tap water will help your plant.
