Amoeba
The amoeba is a protozoan that belongs to the Kingdom Protista. The name ameba comes from the Greek word amoible, which means change. (Amoeba is also spelled ameba.) Protists are microscopic unicellular organisms that don't fit into the other kingdoms. Some protozans are considered plant-like while others are considered animal-like.
AMOEBA
There are two types of cytoplasm in the ameba, the darker cytoplasm toward the interior of the protozan is called endoplasm, and the clearer cytoplasm that is found near the cell membrane is called ectoplasm.
AMOEBA
Also visible in the ameba is the nucleus, which contains the ameba's DNA. In order to reproduce the ameba goes through mitotic division, where the nucleus duplicates its genetic material and the cytoplasm splits into two new daughter cells, each identical to the original parent.
AMOEBA
During unfavorable conditions, the ameba can create a cyst, this hardwalled body can exist for a long period of time until conditions become favorable again. At this point it opens up and the ameba emerges.
