Eukaryotes or eukaryotic cells
have a cell nucleus and organelles enclosed within membranes. Eukaryotes can be
unicellular or multicellular. Most complex life forms are eukaryotes. In
contrast, prokaryotes don’t have a nucleus and don’t have things like mitochondria
or chloroplasts. Their DNA, proteins, and metabolites swim freely in the
cytoplasm and not enclosed in organelles.

Answer:
The correct answer is peas have characteristics that have two forms.
Gregor Mendel used pea plant <em>Pisum sativum </em>as a model plant for his experiments. There are many applications behind his choice, one of which is observable characteristics with contrasting traits.
Pea plant has many observable characteristics which exist in two forms for example:
- Plant size (tall or dwarf)
- Pea color (green or yellow)
- Pod shape (yellow or green)
- Flower color (purple or white)
- Pea shape (round or wrinkled)
Other benefits were like: short life cycle, it produces a good number of offspring in a cross, easy to breed or cross-pollinate, hybrids were liable, bisexual flowers which makes it easy to produce true-breeding etc.
