Answer:
The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
Explanation:
A mutation is any change, whether big or small, that occurs to the nucleotide sequence of a gene in a cell as caused by mistake during replication or induced by a mutation causing substance. These mutation-causing substances are called MUTAGEN.
A MUTAGEN is any substance that causes genetic mutation in an organism's cell. These changes in the nucleotide sequence can affect one or more phenotypic characteristics of the affected organism, which is also passed to offsprings because it is a genetic change.
Hence, a plant cell exposed to this mutagen will be induced to mutate.
Hence, the cells changing after being exposed to the chemical, which is also passed to the next generation of cells best provides explanation that the chemical is a MUTAGEN.
Explanation:
The molecule is the smallest unit of the substance that retains its characteristic properties. The macromolecule is such a unit but is considerably larger than the ordinary molecule, which usually has a diameter of less than 10 angstroms (10−6 mm).
Answer:
The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

To create a mysterious mood.
Answer and Explanation:
12. The water has a lower osmotic pressure than the cell sap of the root hairs. Due to the osmotic difference water is drawn by osmosis across the cell wall and cell membrane into root hairs. Water moves by osmosis into adjacent cortex cells and their osmotic pressure is lowered drawing water by osmosis. Water passes to the successive cortex cells and through the endodermis to the xylem vessels. At the leaves, the xylem passes into the petiole and then into the veins of the leaf. Water leaves the veins and enters the cells of the spongy and palisade layers.
13. Food and other manufactured material are translocated by the phloem. They enter the sieve elements through plasmodesmata connecting them to adjacent companion cells which are sites of high metabolic activity. The manufactured food are translocated through sieve tube along the cytoplasmic strands.
