Plants cells have many things in common with each other. Plant cells have a fairly large vacuole. They also have a cell wall. This protects them from harmful substances. They all have a goo-like substance in them called chloroplast. The chloroplast captures sunlight in the process of photosynthesis.f you have ever seen a plant cell you will notice that the cell is mostly green.
