CELL MEMBRANE compare to other cells?

plant , animal cells both eukaryotes there differences.

plant cell walls composed of following carbohydrates:

1. cellulose
2. hemicelluloses,
3. pectin
4. lignin,

these carbohydrates secreted protoplast on outside of cell membrane. contrasts cell walls of fungi (which made of chitin, , of bacteria, made of peptidoglycan. rigid layer outside of cell membrane provides cell structural support, protection, , filtering mechanism

there specialized cell cell communication pathways known plasmodesmata, pores in primary cell wall through plasmalemma , endoplasmic reticulum of adjacent cells continuous

inside of cell wall membrane known tonoplast maintains cells turgor, controls movement of molecules between cytosol , sap, , stores useful material , digests waste proteins , organelles.

while animal cells part have ability move on own; plant cells stationary.

animal cell membranes cell membrane surrounds cells , semi-permeable, controlling movement of substances in , out of cells.[2] contains wide variety of biological molecules, proteins , lipids, involved in variety of cellular processes such cell adhesion, ion channel conductance , cell signaling. plasma membrane serves attachment point intracellular cytoskeleton and, if present, extracellular cell wall.

cell membrane surrounds protoplasm of cell and, in animal cells, physically separates intracellular components extracellular environment, thereby serving function similar of skin. in fungi, bacteria, , plants, additional cell wall forms outermost boundary; however, cell wall plays mechanical support role rather role selective boundary[citation needed]. cell membrane plays role in anchoring cytoskeleton provide shape cell, , in attaching extracellular matrix group cells in formation of tissues. barrier differentially permeable , able regulate enters , exits cell, facilitating transport of materials needed survival. movement of substances across membrane can either passive, occurring without input of cellular energy, or active, requiring cell expend energy in moving it. membrane maintains cell potential.
specific proteins embedded in cell membrane can act molecular signals allow cells communicate each other. protein receptors found ubiquitously , function receive signals both environment , other cells. these signals transduced , passed in different form cell. example, hormone binding receptor open ion channel in receptor , allow calcium ions flow cell. other proteins on surface of cell membrane serve "markers" identify cell other cells. interaction of these markers respective receptors forms basis of cell-cell interaction in immune system.
lot of information site, but, if go "www.en.wikipedia.org/wiki/cell_membrane... pictures , diagrams idea of going on.

what cell membrane other cells dont? or have others dont?
answer in detail if u can, answer useful.

if u dont know know other cells or have others dont, u can answer in way.
