Similarities and differences between animal and plant cells

Similarities: all have cell membrane, cytoplasm and nucleus.Differences: animal cells have centrosomes, but only lower plants in plants have centrosomes;Plant cells have cell walls, and some cells have chloroplasts and large central vacuoles, which are not found in animal cells.There are plasmodesmata between cells in higher plants.Animal cells do not have plasmodesmata, but desmosomes and adhesive bands.Structure and function of animal cells Animal cells have nucleus, cytoplasm and membrane, no cell wall, vacuoles are not obvious, contain lysosome, animal cell structure has membrane, cytoplasm, organelles, nucleus.Their main role is to control the entry and exit of cells, carry out material conversion, the main place of life activities, control the life activities of cells.Inside the cell are organelles, nuclei, double membranes, and chromosomes made up of DNA and proteins.The rough endoplasmic reticulum has ribosomes attached to its surface, which are involved in protein synthesis and processing, while the smooth endoplasmic reticulum has no ribosomes on its surface, which is involved in lipid synthesis.Morphology and structure of plant cells In plants, different organs have different cell groups. For example, the cells that make up the epidermis of leaves are regular in shape, closely arranged and protective. In cell structure, they include cell walls, membranes, nuclei, cytoplasm, vacuoles but no chloroplasts.The cells that make up the vegetative tissue are irregular in shape and provide nutrients to the plant body, but in structure, mesophyll cells include cell wall, cell membrane, nucleus, cytoplasm, vacuole and chloroplast for photosynthesis.
