The diagram below represents a plant cell and three different molecules used by the cell. Molecule 1 is able to ENTER the cell using the process of *

1) Diffusion

2) active transport

Answer is Diffusion.

Diffusion is when a molecule travels from a area of higher concentration to an area of lower concentration.

The concentration of Molecule 1 is greater outside the cell as compared to inside.
2 cells inside vs. 4 cells outside

Therefore, Molecule 1 will enter the cell through diffusion.
