The answer to this question might change based on a fairly important variable that is not listed in the question. The question states that the cell is a eurkaryotic cell, but the question does not specify whether or not the cell is a plant or an animal cell. This would be helpful to know because the size of the vacuoles changes between the two cell types, and the inclusion of chloroplasts might be necessary. The other small variable to take note of is that some of the organelles do vary in size. For example, a nucleus is generally between 5 and 10 micrometers, and a mitochondria can range from 1 to 10 micrometers. A lysosome is around 2 micrometers. The endoplasmic reticulum is built in layers, and each layer is about a half micrometer in thickness. The golgi can range in size as well, but sources generally show it around 1 to 2 micrometers. A chloroplast is around 5 micrometers, and the nucleolus is around 1 to 2 micrometers. Ribosomes are definitely the smallest. They are about .025 micrometers.
