1. Oxygen is not needed by the plant for photosynthesis.
It is a by-product of photosynthesis. Instead Carbondioxide is needed.
2. The glucose produced does not stay solely in the plant, part of it is used up by the plant while others stores in edible parts of the plant that men use as food.
3. The light energy converts H2O to 4H+ and 4OH- needed in the synthesis of carbohydrate and release of Oxygen.
In mitosis (I think it is this process) the 46 chromosomes in cell A replicate themselves, so there are 92 in total in cell B. Then the chromosomes are pulled apart and the cell splits into 2 daughter cells, leaving 46 chromosomes in each.
As earth’s temperatures increase with climate change, the polar ice caps melt and the sea levels rise, leaving islands like Australia at risk of flooding and partial, permanent underwater submersion.
