The clear epidermal cells exist in a single layer and do not contain chloroplasts, because the onion fruiting body (bulb) is used for storing energy, not photosynthesis. [3] Each plant cell has a cell wall, cell membrane, cytoplasm, nucleus, and a large vacuole. The nucleus is present at the periphery of the cytoplasm.
English: A reworked version of File:Biological_cell.svg. Diagram of a typical animal cell. Organelles are labelled as follows: Nucleolus; Nucleus; Ribosomes (dots on rough reticulum walls) Vesicle; Rough endoplasmic reticulum; Golgi apparatus (or "Golgi body") Cytoskeleton; Smooth endoplasmic reticulum; Mitochondrion; Vacuole; Cytosol; Lysosome ...
An onion (Allium cepa L., from Latin cepa meaning "onion"), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus Allium. The shallot is a botanical variety of the onion which was classified as a separate species until 2011.

Diagram of the plant cell, with the cell wall in green. Cell walls serve similar purposes in those organisms that possess them. They may give cells rigidity and strength, offering protection against mechanical stress. The chemical composition and mechanical properties of the cell wall are linked with plant cell growth and morphogenesis. [11]
The central and rightmost cell are in interphase, so their DNA is diffuse and the entire nuclei are labelled. The cell on the left is going through mitosis and its chromosomes have condensed. Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell.
Christmas or Hanukkah travel is underway for millions, and the weather may be a factor. For some, snow, rain, even a little ice could disrupt your plans.
Mitosis divides the chromosomes in a cell nucleus.
