Bumblebees of the subgenus Psithyrus (known as 'cuckoo bumblebees', and formerly considered a separate genus) are brood parasites, sometimes called kleptoparasites, in the colonies of other bumblebees, and have lost the ability to collect pollen.
A eukaryotic cell is any cell with a true nucleus and organelles. The nucleus contains the majority of the cellâs DNA and is the genetic hub of the cell. Organelles are membrane bound structures found inside eukaryotic cells and they play a similar role to the organs of the body.Organelles perform certain roles to help the cell function more efficiently.he organelles and nucleus float in the cytoplasm of a cell. Ribosomes â produce proteins. Ribosomes are not true organelles because they are not enclosed in a membrane. Ribosomes can also be found in prokaryotic cells.
Organelles are simply membrane-bound compartments within a cell, such as the nucleus, mitochondria, chloroplasts, golgi, and endoplasmic reticulum. You are a eukaryote. Your cells are eukaryotic. Eukaryotic cells contain membrane-bound organelles, including a nucleus.Eukaryotes can be single-celled or multicelled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.Prokaryotes include two groups: bacteria and another group called archaea. Having organelles is a big deal for a cell.rokaryotic cells do not contain a nucleus or any other membrane-bound organelle. Prokaryotes include two groups: bacteria and another group called archaea.
