What are the adaptations of a water hyacinth?
The primary adaptation of the water hyacinth,Eichhoria crassipes , is its hollow bulbous stem below each leaf. These allow the plants to float, keeping the leaves and flowers above the water so they don't rot. The water hyacinth mainly reproduces through stolons. This adaptation allows for a single plant to produce approximately 3,000 new plants in as little as 50 days or cover 600 square meters in as little as a year. Also, the water hyacinth seeds are adapted to be dispersed by birds and can remain viable for up to 20 years.The water hyacinth has other adaptations that allow it to grow and spread rapidly in freshwater. Its swollen leaf stalks are hollow and filled with air. This allows it to be the only large aquatic herb that floats unattached from the bottom of its water source. The roots remain underwater in a thick mat, allowing the plant to obtain enough sunlight for photosynthetic processes. They have also adapted to withstand extreme temperatures, high pH levels and even toxic water.Water hyacinths are extremely tolerant of heavy metals and can contain large amounts of them. This makes the plant a possible resource for bio-cleaning industrial waste. They have also been well known to remove toxic materials such as cyanide from water.
I study a lot, but I always forget almost all that I've studied. What should I do?
This used to happen to me and I was considered average student, I too believed I'll forget what I read bcoz I had poor memoryBut in real life I had great memory for details and remembered everything, when it comes to paying attention to girls and closed ones How can this be??You can only remember which is important to you, so everyone has a same ability when it comes to memory, brain discards which you feel is not important and if it's not revised !!1.Revision is the key - ‘don't worry if your friends remembers reading it only once' They are just storing it to short-term memoryIf there was one thing which changed me from failed student to above average is revision ( It's worth giving your mind test that you really remember or not before attempting to remember in exam hall ) so revise well beforeRevise as soon as you learn and revise before exam2.(learn about memory graphs)** Best tip I can give is**3) Everything in 1 single sheet - You can't go through all the stuffs in last moments, but if you can manage the skill to write it in single paper all the things you have studied(You'll improve this skill with time)This is the only thing I go through before going to examThis is example of the sheet how I doTake a sheet of double sheet paper fold it into 4parts you'll have 8parts to fill now, break down everything into mnemonics story and diagrams4)MnemonicsThis technique becomes fun with practice5)Memory palace...Lot more to tell !!!But I think this is enough ,I got exams tomorrow so..I think others answers would have covered everything what I may have leftFinal tip for you and me- stop wasting time here, go study !!
