Explanation:

1. The cell - wall (J) is the thick surface structure that gives shape, support and protection to plant cells.
2. The nucleus (A) is the control center of the cell, directing all cell activities and involved in cell division.
3. Mitochondria (M) release energy for cell functions and are known as the powerhouse of the cell.
4. Ribosomes (C) are the "factories" for building proteins.
5. The endoplasmic reticulum (O) is like "roadways" for moving materials throughout the cell.
6. The nucleolus (K) manufactures ribosome parts (proteins and RNA).
7. Cytoplasm (N) is the sticky, semi - fluid material inside a living cell in which other cell organelles are suspended.
8. Lysosomes (G) contain digestive enzymes.
9. The nuclear membrane (L) encloses the cell's genetic material.
10. Vacuoles (D) are storehouses for excess water, food, wastes, etc.
11. Chloroplasts (B) are the green organelles of plant cells where photosynthesis takes place.
12. Golgi bodies (F) package useful materials and secrete them to the outside of the cell.
13. Chromatin (I) are strands within the nucleus which form chromosomes.
14. The cell membrane (H) holds the contents of the cell together.
15. DNA (E) is the hereditary material that carries the genetic code.
