Plant cells are fairly consistent across species in shape and build. The vacuole will appear as a large water-filled sac that takes up the vast majority of the cell. Due to the plant's inability to search for food or water sources on its own, plant cells require a large storage space to store what materials they can find, which is the vacuole that takes up 60%-70% of the space inside of the cell.
Chromosomes are the DNA structures that all eukaryotic cells have in their nuclei. Plant cells are no different and their chromosomes can be found as small x-shaped structures stored inside of their nucleus just inside of the nuclear membrane. This may also be seen as chromatin, which is one half of a chromosome before it has been replicated.
The cytoplasm is the jelly-like fluid that fills the rest of the cell. The organelles float and move around inside the cytoplasm and pass around materials through it. This is also where proteins are made, waste products and nutrients can be found being sent from organelle to organelle, and most general activities happen.
Linked below are some good diagrams.
