Photosynthesis is an endergonic reaction. why?

Photosynthesis is an endergonic reaction because the plants are absorbing light energy. It's not heat energy but light energy. So they're absorbing that energy to make new stuff.

Photosynthesis cannot happen without adding energy. The energy from that comes from the sun.

this would be a math

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
