Prokaryotes: the simplest and oldest form of life, single celled, start of live/where all life came from, they can live in any environment on Earth, bacteria are the only prokaryotes. They DO NOT have a nucleus. Tails help them move along with little hairs around the cell. No organelles, they have circular chromosomes, they're unicellular or colonial, they have a cell wall and cell membrane.
Eukaryotes: Have a nucleus as well as organelles, linear chromosomes, have a cell wall (plants&fungus), have a cell membrane.
If two homozygous plants with contrasting traits are crossed, the
expected genotypes for the offspring will be heterozygous. The
dominant trait would be expressed, but they'd be carriers for the
recessive trait.
