Bacteria typically have simpler shapes such as rods, spheres, or spirals, whereas protists have a more diverse range of shapes including spheres, rods, spirals, filaments, and various other forms. Protists exhibit a wider variety of shapes due to their more complex cellular structures and functions compared to bacteria.
Archaea bacteria has a similar cell organization to regular bacteria. They are simple, single cell organisms. Like other bacteria, they have no cell nucleus. They are around 5 micro meters long.
Unicellular
Prokaryotic cells have various shapes; the four basic shapes are:Cocci - sphericalBacilli - rod shapedSpirochaete - spiral shapedVibrio - comma shaped
a tight chain
Viruses are not cells and are not made of cells: they are small entities that reproduce inside of cells.Viruses have many different shapes and forms. They tend to resemble spirals, spheres, and various types of three-dimensional polygons.The internal structure of a virus is a strand of RNA surrounded by a protein shell.
No, not all bacteria have a spiral shape. Bacteria come in various shapes such as spheres (cocci), rods (bacilli), and spirals (spirilla). The shape of a bacterium is determined by its cell wall structure and genetic makeup.
because of the varying shapes of the nucleus, which is usually lobed into three segments.
Its called BACCILLI the circular shapeds are COCCI(pronouced cox-i) and the spirals are spirilla
The nucleus of the cell contains the genome.
Bacteria are microscopic organisms that can have various shapes, such as spheres (cocci), rods (bacilli), or spirals. They can appear individually or in chains or clusters. Bacteria can be seen under a microscope, but they are too small to be visible with the naked eye.
the nucleus is the brain of the cell.
