Plant cells form, of course, all types of plants and roots, butalso form vegetables and fruits and grains. Any organisms that areplants are made up of plant cells. They all belong to the kingdomPlantae. Organisms such as animals, bacteria, etc. are not made upof plant cells. The reason why this is is because plant cells haveorganelles called chloroplasts which help the plant tophotosynthesize. Photosynthesis allows plants to make their ownfood, which is what sets them apart from other organisms. Someexamples of these are flowers, grass, trees, corn, wheat, vines,weeds, and shrubs.
