Which type of cell would bacteria be?
Is bacteria considered a cell?
Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA.
Why do platelets have no nucleus?
Activated platelets are round with projections. Like red blood cells, platelets are derived from myeloid stem cells. Some of these stem cells develop into megakaryoblasts, which give rise to cells called megakaryocytes in the bone marrow. Because they are not cells, platelets don’t have their own nuclei.
What are the two major types of eukaryotes?
Eukaryotic cells may be classified into two groups based on the number of cells that make an individual organism: (1) unicellular eukaryotic cells and (2) multicellular eukaryotic cells.
What are eukaryotes examples?
Eukaryote refers to any of the single-celled or multicellular organisms whose cell contains a distinct, membrane-bound nucleus. Organisms such as animals, plants, fungi, and protists are examples of eukaryotes because their cells are organized into compartmentalized structures called organelles, such as the nucleus.
Are humans prokaryotic or eukaryotic?
Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. This means that all human cells—including those found in the brain, the heart, the muscles, and so on—are also eukaryotic.
Are humans considered eukaryotic?
The nucleus is often referred to as the control center, or brain, of the cell and contains the DNA, or genetic material. Cells that contain these features (ie, cytoskeleton, organelles surrounded by cytoplasm and nucleus surrounded by nuclear envelope) are called eukaryotic cells. Human cells are eukaryotic cells.
