when the cell divides.

1. material outside the nucleus and

inside the plasma membrane.

1. modifies and packages proteins.
2. contain enzymes that digest

nonusable materials within the cell.

1. non-functioning units.

Explanation:

1. Ribosomes (C, D) are made of protein and RNA.
2. Plasma Membrane (E) is a phospholipid bilayer with hydrophilic heads and hydrophobic tails.
3. Smooth Endoplasmic Reticulum (A) functions in drug detoxification.
4. Smooth Endoplasmic Reticulum (A) is the site for forming cellular membrane building materials.
5. Ribosomes (C, D) are sites of protein synthesis.
6. Nucleoli (G) are sites of ribosome production.
7. Nuclear Membrane (H) has nuclear pores for material exchange.
8. Peroxisomes (F) break down free radicals.
9. Mitochondria (I) carry out oxygen - using food - breakdown reactions.
10. Microvilli (J) are finger - like for absorption surface area increase.
11. Chromatin (O) condenses to form chromosomes during cell division.
12. Cytoplasm (N) is the material outside the nucleus and inside the plasma membrane.
13. Golgi Apparatus (M) modifies and packages proteins.
14. Lysosomes (K) contain enzymes for digesting nonusable materials.
15. Inclusions (L) are non - functioning units.
