Answer:
A Its cells take in water and nutrients
B. Its cells get larger in size
D. The number of cells in its body increases
Explanation:
An organism's growth is characterized by increase. However, this growth is induced at the cellular level because the occurrences in the cell causes the changes in the organism as a whole. The following occurs to the cells of a multicellular organism as it grows:
- Its cells take in water and nutrients: Water and nutrients are vital components for any organism's survival. Hence, the cell of a multicellular organism takes in water and nutrients to carry out certain metabolic processes.
- Its cells get larger in size: As cells in a multicellular organism divides, they also increase in size or volume
- The number of cells in its body increases: Cells increase in number via a process called mitosis. This causes the different parts of the multicellular organism to grow
