Chloroplast cell.
Cytoplasm is a clear substance that is gel-like in the cell membrane but is on the outside of the nucleus. It contains mostly water with the addition of enzymes, organelles, salts and organic molecules. Cytoplasm will liquefy when it is stirred or agitated. It is often referred to as cytosol, meaning "substance of the cell."

The chloroplast is the site of food synthesis for plant cells, by a mechanism known as photosynthesis. Chloroplasts contain chlorophyll, a green pigment that absorbs light energy from the sun for photosynthesis. The plant cells which contain chloroplasts are usually parenchyma cells, though chloroplasts can also be found in collenchyma tissue. A plant cell which contains chloroplasts is known as a chlorenchyma cell. A typical chlorenchyma cell of a land plant contains about 10 to 100 chloroplasts.
Figure 1 Not all cells of a leaf carry out photosynthesis. Cells within the middle layer of a leaf have chloroplasts, which contain the photosynthetic apparatus. (credit Zephyris; wikimedia) The gas exchange of carbon dioxide and oxygen occurs through small, regulated openings called stomata. Figure 2 Tomato leaf stomate (singular of stomata).Animal cells do not have a cell wall. When looking under a microscope, the cell wall is an easy way to distinguish plant cells. Chloroplasts . Plants are autotrophs; they produce energy from sunlight through the process of photosynthesis, for which they use cell organelles called chloroplasts. Animal cells do not have chloroplasts. Chloroplasts are tiny plant powerhouses that capture light energy to produce the starches and sugars that fuel plant growth.
