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 simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series.
Description: The image is a corrected version of an image i made sometime ago. the original quate on the image was "the image describes the parts on a typical plant cell. the image i made myself as resources i used the simple structure here, also the one i found hereand must of the text i could get from here as external source i used another structure found on the book "molecular cell biology ...
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]
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

The onion plant (Allium cepa), also known as the bulb onion [2] or common onion, [3] is the most widely cultivated species of the genus Allium. [4] [5] It was first officially described by Carl Linnaeus in his 1753 work Species Plantarum. [6] Synonyms during its taxonomic history are: [7] [8] Allium cepa var. aggregatum – G. Don
as external source i used another structure found on the book "molecular cell biology" from james darnell, harvey lodish and david baltimore. i tried to convine all in a complete yet simple diagram. i finish it on the 03-feb-05 —LadyofHats 01:12, 3 Feb 2005 (UTC)" Between the changes made are:
