How is plant cell cytokinesis different from animal cell cytokinesis?

#Unit 5. Developmental Biology
  1. The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins.

  2. Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

  3. The structural proteins of plant cells separate the two cells; in animal cells, a cell membrane separates the two daughter cells.

  4. Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase.

Sucrose is split into its two monosaccharide units—glucose and fructose—which can readily enter the glycolytic pathway. Two pathways for the splitting of sucrose are known in plants, both of which take part in the use of sucrose from phloem unloading; Invertase pathway and sucrose synthase pathway, some statements are given about these pathways, which of the following is incorrect?
