The cell membrane is a flexible structure that surrounds both plant and animal cells. The arrangement of molecules within the ce
ll membrane makes it semi-permeable. That is, the cell membrane allows some substances to easily diffuse into and out of the cell, but it prevents the diffusion of other substances. Plant and animal cell diagram
The cell wall is a rigid structure that surrounds plant cells. The materials found in the cell wall protect the plant cells and give plants structural support.
Plant cells are also able to become longer as they grow. ... Cell elongation does not occur in animals. The cells of multicellular animals and plants must also differentiate , so that its cells develop features that enable them to fulfil specific roles. Cells that have differentiated have become specialised.
Similarly to their eukaryotic counterparts, bacterial chromosomes perform the complex task of efficiently compacting DNA while supporting gene regulation and proper DNA segregation. Chromosomes are thus shaped at multiple scales by a large number of proteins and DNA enzymes
