The gel like fluid in a cell is CYTOPLASM. The CHLOROPLAST is the part of only an plant cell that make the plants food through photosynthesis. It captures light and uses it to make the plants food. Chlorophyll is a green pigment in the cell that makes the stem and leaves of plants green.
Neither animal cells or plants cells have something called "chloroplasium". Both kinds of cells have "cytoplasm" which is the jelly-like substance that fills the inside of the cell and in which many of the chemical reactions that keep the cell alive take place. Plants cells also have "chloroplasts" which are the organelles in which photosynthesis takes place; and they are filled with "chlorophyll" this is the chemical which is essential to photosynthesis and gives plants their green colour. I think you are getting confused with one of the other terms maybe?
