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.

The birth of 100 cockroaches to a population of 1,000 would represent a birth rate. Similarly, the death of 50 cockroaches in a population of 1,000 would be a death rate, d, per individual per week. Calculate the rate of change in a population per unit time ?
