Agroup of plant cells was exposed to radiation, which damaged the chloroplasts and caused them to lose function. if the mitochondria were unharmed, what would happen to the overall function of the plant cells? a. the cells would not be able to release energy from biomolecules, but would be able to make food. b. the cells would not be able to break down waste, but would be able to replicate dna. c. the cells would not be able to replicate dna, but would be able to break down waste. d. the cells would not be able to make food, but would be able to release energy from biomolecules.

Option D, The cells would not be able to make food, but would be able to release energy from biomolecules.

Explanation: We should first understand roles of these two organelles in plant cell. Chloroplast- its function is to absorb sun's energy and convert the CO2 into glucose. Mitochondria- It makes energy from glucose and other molecules present in plant cell.

So, its obvious if chloroplast is not working, food will not be formed. That's why option A is incorrect. Again, functions mentioned in Option B are also incorrect, as DNA replication takes place inside the nucleus, and waste is broken down by lysosomes. Same is the reason with Option C, so its wrong option. Only Option D describes the functions correctly.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
