The kind of organism that he found will be Plant.
The cell structure of plants and animals differ in many ways. The cell structure of plants contains a cell wall, the Central Vacuole, Plastids, Chloroplasts, etc. The cell structure has a rigid and strong layer known as cell wall. This forms the outermost layer of the cell.
The Central Vacuole is found in the structure of matured plants. 30% of volume of the cell will be occupied with this. The organelles that helps plants in the process of photosynthesis is plastids. They contain two important things in it such as ribosomes and DNA. The three main types of plastids found in plant cells are chloroplast, chromoplast and leucoplast.
