I am going to say A because a cell makes up matter of the tree so when it duplicates it makes the tree taller..
Please tell me if this is correct or not.. thanks!!
Explanation:
Chromosomes carry DNA which is the genetic material of that organism.
WHILE.
Chromatids help the cell to duplicate and in turn aid in cell division.
I HOPE THIS HELPS
M, G1, S, and G2. M is mitosis and followed by cytokinesis. S phase is the period when DNA replication occurs.
