What organelle forms the spindle in animal cells? - Answers
WebThe spindle apparatus consists of spindle fibres, motor proteins, chromosomes, and, in some cells, structures called asters. In animal cells, spindle fibres are produced from cylindrical microtubules called centrioles. Centrioles form asters and asters generate spindle fibres during the cell cycle. So, the correct word is 'centriole'. WebIn most animal cells, a network of actin filaments is found in the region of cytoplasm at the very edge of the cell. This network, which is linked to the plasma membrane by special connector proteins, gives the cell shape and structure 2 , 3 ^{2,3} 2 , 3 start superscript, 2, comma, 3, end superscript . portcath hickmans
