3 0

Answer:

Photosynthetic cotyledons remain on the plant until the first true leaves appear and can begin to perform photosynthesis. This is generally just a few days and then the seed leaves fall off. They remain to help direct the energy stored in the seed to new growth, but once the plant is self-sufficient, they are no longer needed.

4. but it is known that MOST enzyme assisted reactions ARE reversible.

so option 4 is true.
