Three dimensional shapes are shapes with height, width, and depth. In contrast, two dimensional shapes only have height and width, or length and width.
Shapes which can be measured in 3 directions are called three-dimensional shapes. These shapes are also called solids. Length, width, and height (or depth or thickness) are the three measurements of the three-dimensional shapes. These are the part of three-dimensional geometry.
In geometry three-dimensional shapes are solid figures or objects or shapes that have three dimensions length, width, and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth. A cube and cuboid are examples of three-dimensional objects, as they have length, width, and height.
The difference is that two-dimensional shapes have a length and a width while three-dimensional shapes have a length, width, and depth. While some examples of two-dimensional shapes are circle, rectangle, and triangle, example of three-dimensional figures are a sphere, cuboid, and a pyramid.
The sun and the moon are spheres... and maybe mountains are cones?
shapes of prokaryotes
Bacillius, Spirillius and Cocci.
Since you asked about the main organelle, singular, I will have to say....The membrane bound nucleus that eukaryotes have and prokaryotes do not.
Round , rod and spiral .
Transformers come in many shapes. Cylindrical, square, and rectangular are three of the main shapes of transformers.
The most common prokaryotes are bacteria. These refers to organisms that are usually single-celled and mainly are in spherical, helical and rod shapes.
There are three main differences between prokaryotes and eukaryotes. Prokaryotes lack a cell nucleus while eukaryotes are made up of cells that all contain a membrane bound nucleus. While prokaryotes have a single cell make-up, eukaryotes have multiple cells. Prokaryotes has DNA without any real structure, while eukaryotes has a well structured DNA system that is organized into chromosomes.
Archeobactetia
Prokaryotes are organisms that are usually small single cells but some have multi-cells. Prokaryotic cells are archaea and bacteria with shapes that depend on species.
There are three main shapes for simple leaves: ovate (egg-shaped), lanceolate (long and narrow), and elliptical (oval). These shapes can vary slightly depending on the species, but most simple leaves can be categorized into one of these three shapes.
There are the the spiral, elliptical, and irregular galaxy formations.
cylindrical shape doesn't describe for the bacterial cell shapes
