photosintesis
The process of photosynthesis occurs inside the plant cell.With the help of photosynthesis plant cells make their food.Without photosynthesis plant cells will function very poorly.
Photosynthesis is the process whereby a green plant gains energy. To do so, it uses solar energy (absorbed through the leaves) combined with nutrients from the soil, water and carbondioxide. This allows the plant to bond and store energy, and produces oxygen as a result.
"When you needed was there" is bad grammar. It has to include the word "me" or "he" or "she" or "us" or "them" as in "When you needed me, I was there" or "When you needed her, she was there" or "When you needed him, he was there", or "When you needed us, we were there" or "When you needed them, they were there" in order to make sense.
