#SCPH28 | Zoology
  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.

In areas of permafrost, stands of black spruce are frequently observed in the landscape, while other tree species are noticeably absent. Often these stands are referred to as "drunken forests" because many of the black spruce often "lean over" (that is, they are displaced from their normal vertical alignment). What is the most likely explanation for the unusual growth of these forests in this marginal habitat?
