Plant cells vs animal cells?


there several differences,
1. plant cells have cell wall made of cellulose (peptidoglycan in prokaryotes.) re-inforce cell , prevents plasmolysis in hypotonic environement. infact, hydraulic turgor pressure creates rigidity, along wall structure. flexibility of cell walls seen when plants wilt, stems , leaves begin droop, or in seaweeds bend in water currents. animal cell has no cell wall , burst when imersed in hypotonic solution.
2. plants have central vacoule, called tonoplast, helps mantain turgor, controls movement of molecules between cytosol , sap, stores useful material , digests waste proteins , organelles.
3. cell communication between plant occurs through called "plasmodesmata," these microscopic channels linking cells. these occur in form of "gap junctions" in animal cells. simular not identicle.
4. plants cells contain organelles collectively known plastids, notably chloroplasts contain chlorophyll , biochemical systems light harvesting , photosynthesis, amyloplasts specialized starch storage, elaioplasts specialized fat storage , chromoplasts specialized synthesis , storage of pigments
5. plant cells stationary, animal cells not
6. animal cells have called centrioles orients microtuble spindle formation during mitosis. orients direction of cell division. plant cells have no such organelles.
7. cytokinesis in plant cells occurs via. cell wall formation between 2 daughter cells following telophase. accomplished formation of cellulose on endoplasmic reticulum , deposited along th called "cell plate" during cytokinesis. process ocurrs via cleavage furrow in animal cells contractile ring composed of actin , myosin form , "pinches" 2 cells appart. contractile machinery opperates in muscle tissue.
8. most, not plant cell sperm lack flagella present on animal spermatoyctes.

SOMEONE WITH COMPUTER KNOWLEDGE PLEASE HELP ME!?

Is there any website which would tell the history if we provide the second name or surname?
