Plant cells have some specialized properties that make them distinct from animal cells. Plant cells with visible chloroplasts. The root cap (the cells at the tip of the root) have some specialized cells called statocyte (stat = position, and cyte = cell). A plant cell which contains chloroplasts is known as a chlorenchyma cell. The organelles are only found in plant cells and some protists such as algae. The main idea is that there are not a fixed number of chloroplasts in elodea cell. The chloroplast is located throughout the cytoplasm of the cells of plant leaves and other parts depending on the type of plant. D. A plant cell can become a blood cell. The number of chloroplasts in plant cells differs for unicellular and plant leaf cells. When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy found in compounds such as ATP and NADPH. A cross section of a leaf, showing chloroplasts in its mesophyll cells. This color change is due to the plant. 2011, Sage et al. Also read: Golgi Apparatus.
