Answer:
Amoeba are unicellular eukaryotes found in aquatic environments. The organelle that is found in amoeba are nucleus, contractile vacuole and food vacuole and organelle found in plant cells are nucleus, endoplasmic reticulum, Golgi apparatus, vacuole, chloroplast, mitochondria, peroxisomes.
The organelles that are common in amoeba and plant cells are nucleus and vacuole. Both plant and amoeba have a membrane-bound nucleus in which their genetic material is packed.
The role of the vacuole in plant cell and amoeba is that it maintains the proper osmotic pressure in the cell and prevent cell from bursting. It also helps in the collection of waste material and its disposal.
