When does plants start to photosynthesis

During photosynthesis, a plant translates , water and light into . I assume the carbon is further used for the growing process. I wonder how the plant grows before the time where photosynthesis is possible, i.e. before there are even leaves, in which photosynthesis occurs.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

hope this !

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
