cytokinesis in plant cells involves the formation of
spindle fibers.
centrioles.
replicated chromosomes.
a cell plate.

Explanation:

To solve this, we analyze each option:

• Spindle fibers are involved in chromosome separation during mitosis (not specific to plant cytokinesis).
• Centrioles are absent in most plant cells and not part of plant cytokinesis.
• Replicated chromosomes are part of mitosis (nuclear division), not cytokinesis (cytoplasmic division).
• During plant cytokinesis, a cell plate forms, which develops into the cell wall separating the two daughter cells.

Answer:

D. a cell plate.
