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 ...
[178] [179] The characteristic features of plant cells that distinguish them from those of animals and fungi include a primary cell wall composed of the polysaccharides cellulose, hemicellulose and pectin, [180] larger vacuoles than in animal cells and the presence of plastids with unique photosynthetic and biosynthetic functions as in the ...
Discoveries in plant cells since the 1970s started to challenge this definition. Plant vacuoles are found to be much more diverse in structure and function than previously thought. [ 60 ] [ 61 ] Some vacuoles contain their own hydrolytic enzymes and perform the classic lysosomal activity, which is autophagy.
Original - This is a schematic view of an typical animal cell. An animal cell is a form of eukaryotic cell that makes up many tissues in animals. Reason well labeled, encyclopedic, high quality SVG. i am renominating it sepratly because last time it was one of the concern.

In eukaryotes (i.e., animal, plant, fungal, and protist cells), there are two distinct types of cell division: mitosis and meiosis. [59] Mitosis is part of the cell cycle, in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.
Plant cytokinesis differs from animal cytokinesis, partly because of the rigidity of plant cell walls. Instead of plant cells forming a cleavage furrow such as develops between animal daughter cells, a dividing structure known as the cell plate forms in the cytoplasm and grows into a new, doubled cell wall between plant daughter cells.
In fact one systematic review and meta-analysis published in Nutrients in 2021, which compared plant protein versus animal protein when it comes to lean muscle mass, found that there was a ...
Both plants and animals have NLR proteins which seem to have the same biological function – to induce cell death. The N-termini of plant and animal NLRs vary but it seems that both have LRR domains at the C-terminus. [33] A big difference between animal and plant NLRs is in what they recognise. Animal NLRs mainly recognise pathogen-associated ...
