Plants can die if they are not replanted as they outgrow their pot. The roots need room to grow and spread out in order to get the nutrients the plant needs.
in polysaccharidesthe roots make extended room.
my thoughts are this a plant has a specific volume need for water it can vary based on availability of sunlight and how much room the roots have to grow as well as species type and place of origin. To much water can often kill a plant as surely as not enough. If your plant isn't growing and it is not waterlogged or deprived of sunlight (which it needs to effectively fuel its use of the water and soil nutrients) check if its roots are cramped or the water may have a substance that kills the plant.
They do need space because if they don't the plant doesn't have any room to expand it's roots. So it wouldn't be able to get water and die.
If a plant gets too much water, the plant will rot. water builds up in the soil until there is no room for oxygen, and the roots die. when the roots die, the plant can no longer take up nutrients, and it slowly rots. otherwise a fungal infection will develop and also rot the plant.
to get oxygen for the plant or because there wasn't enough room to grow in the soil
Too much water and it will become root-bound ... the ground surrounding the plant will get moldy and then stricken the plant with diseases. Don't think a plant can get too much sunlight ... there's a difference between "sunlight" and "full sun". Sunlight is somewhat diffused.
yes, if the plants roots doesn't have room to grow they will set crammed into the bottom of the pot, there fore the plant might not absorb all the nutrients it needs
Yes it would. There is of course a maximum size a plant will grow but if it has too little space to expand in size it won't.
it will grow to big so it will need more room to live
A wolf needs to have plant of room to roam free. There is not certain amount of space. They can run hundreds of miles a day.
Neither. Tepid or room temperature water is generally considered the best for house plants. The following URL will take you to an article from The New York Times published in 1878 where the author uses very hot water as an unusual plant remedy. http://query.nytimes.com/gst/abstract.HTML?res=9D03E7D9113FE63BBC4F52DFB4668383669FDE I'm not sure I'd try it on an expensive or much loved plant until I'd experimented a bit.
