On what grounds can a tomato be classified as a dicotyledonous plant? How do plants of the Solanaceous family differ from the pink family?

In dicotyledonous plants, the leaf venation is reticulate, the root system is pivotal, the cotyledons in the seed are 2.

If we look at the leaves of a tomato, we will see that the veins on the leaf are reticulated, which means that the root system is pivotal and the number of cotyledons in the seed is 2.

In plants of the Rosaceae family, the flower consists of 5 non-accrete sepals and 5 non-accrete petals, many stamens and pistils (some have 1 pistil). The fruit is an apple, a drupe.

Solanaceae, in contrast to Rosaceae, have 5 fused sepals and 5 fused petals into a tube; 5 stamens and 1 pistil. Fruits – a berry, a box.
