The nucleus was the first organelle to be discovered. What is most likely the oldest preserved drawing dates back to the early microscopist Antonie van Leeuwenhoek (1632 – 1723).
The nucleolus is often represented by a spherical or oval shape within the nucleus of a cell, depicted as a dense, dark-staining region. It is primarily associated with the production of ribosomal RNA (rRNA) and the assembly of ribosomes. In diagrams, it is commonly illustrated as a prominent, compact structure surrounded by the lighter staining nucleoplasm of the nucleus.
Mitochondria are commonly referred to as the (eukaryotic) cell's "powerhouse".
Ribosome in a eukaryote is formed in the cytoplasm and definitely not in the nucleolus of the nucleus . There seems to be a confusion between ribosomes and ribosomal sub units . Ribosomal sub units are indeed formed in the ncleolus . yes , agreed . But when some body raises a questions 'Where exactly ribosomes are formed ' ? The answer is - cytoplasm and definitely not nucleolus . What do my friends who read this say !!!
No, a marble is typically spherical in shape. It is not commonly shaped as an oval.
Without access to the specific diagram you're referring to, I can't identify "organelle 1" directly. However, if "organelle 1" is commonly a nucleus, its function is to store genetic information and coordinate cellular activities, such as growth, metabolism, and reproduction. If it refers to another organelle, such as a mitochondrion, it would be responsible for energy production through cellular respiration. Please provide more context or specify the organelle for a more accurate description.

Soccer balls are not always spherical in shape; commonly, the surface of a soccer ball is composed of many hexagonal patches that are slightly ridged.
No, a marble is typically spherical in shape. It is not commonly shaped as an oval.
A piece of glass with one or two spherical surfaces is called a lens. Lenses are commonly used in optics to refract light and focus images.
Micrococcus luteus is a spherical bacterium, typically measuring around 0.5 to 2.5 micrometers in diameter. It is commonly found in soil, water, and air. Its shape is described as cocci, which means it has a round or spherical morphology.
Aspheric lenses have a more complex curved surface compared to spherical lenses, which have a uniform curvature. Aspheric lenses can reduce spherical aberration and distortion, resulting in better image quality and clarity. They also provide a wider field of view and reduce glare and reflections. Spherical lenses, on the other hand, are simpler in design and are more commonly used in eyeglasses.
The tissue with centrally located spherical nuclei is typically simple cuboidal epithelium. This type of epithelium consists of a single layer of cube-shaped cells, each containing a centrally positioned spherical nucleus. It is commonly found in glandular tissues and the lining of kidney tubules, where it plays a role in secretion and absorption.
Opals are generally elliptical in shape, are in some cases pear or spherical. Angular shapes for opals are not commonly seen.

Cyanobacteria are prokaryotes. They lack a membrane-bound nucleus and other organelles commonly found in eukaryotic cells.
