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.

#Unit 1. Molecules and their Interaction Relevant to Biology

As atom "A" approaches, the electrons of atom "B" will be attracted by the positive end of atom "A". As a result, the electrons of atom "B" will migrate to the left side and make the left side slightly negative. This phenomenon can be explained by
