testa is the seed coat...however i hope somebody tells you what is peri carp cuz its not coming to my mind right now...

pericarp is the fruit wall!..but i dont ctually understand the diff b/w dem..

 

[Spidey21]

well the fruit wall and the seed coat ... whats the similarity?? they are both different things...one is the cover of the seed and the other is the cover for the fruit...
just read once more from your text book, i think then you will get it...
Suggestion : Read the whole chapter..

the problem is testa isn't explained in ma book!..nut still thanku!

NUT??? LOL...didnt get that part...why dont you check on google?? and i think this should help you understand that Testa and Pericarp are the coats of Seed and the fruit respectively...

sorry i misspelled!..i wanted to write but and nt "nut"...lol......well thanku i already understood it!..

Well i kind of forgot the question can u tell me the year again but why dont u check the ms for this it tells u all answers !

now i think i will have to answer your question...

 

[Spidey21]

pericarp is the fruit wall!..but i dont ctually understand the diff b/w dem..

the best answer i got from the book was that
Testa is the protective layer (coat) for the seed and Pericarp is the protective layer for the fruit...

what is the difference between testa and pericarp?

testa is the SEED COAT but pericarp is the Fruit's wall or outer layer

wat is the action of bipolar npn transistor as an electrically operated switch? nd by the way WAT IS A TRANSISTOR? plz help

Pericarp is the fruit wall like the mangoes outer covering !

thankyou!!..

same question here!..:/

wat is the action of bipolar npn transistor as an electrically operated switch? nd by the way WAT IS A TRANSISTOR? plz help

is this included in our syllabus? anyway i have answered what i found out during studying below

npn is a normal transistor. it actually has three connections, the base(showed by connection with straight line), the collector(not marked), and the output (marked by an arrow). the simple working is like this that if the base voltage is high, the transistor becomes active (like a switch is on), and if the base voltage is low, the transistor becomes deactivated ( like a switch is off).

hope my post helped you!

Well i think it is but its part of that optional part which i guess no one does,they just read it for being on safe side

well my teacher taught about NPN transistors and PNP transistors , p-type semi conductors and n-type semi conductors...!

what is difference between insect pollinated flower and wind pollinated flower

well i just found out dat ds npn transistor is very explained in abott!..so y dont u read through it?..its quiet nicely explained there!..

 

[fatikhalid]

what is difference between insect pollinated flower and wind pollinated flower

in an insect pollinated flower the insects help to pollinate the flower by transfering the pollen grains from one flower to another or from the anthers of the same plant to the stigmas of the same plant whereas in a wind pollinated flower the wind helps to transfer pollens from one plant to another

i hope it helped!..

PNP isn't included in our syllabus!
