column b - functions
a. controls what enters and leaves the cell; provides protection and support.
b. contains enzymes that break down waste and worn - out cell parts.
c. site of protein synthesis.
d. jelly - like fluid where organelles are suspended.
e. tail - like, provides movement.
f. stores water, nutrients, and waste products.
g. converts sunlight into chemical energy (photosynthesis).
h. organizes cell division in animal cells.
i. modifies, sorts, and packages proteins for transport.
j. provides structure and protection for plant cells; made of cellulose.
k. short hairs, provide movement.
l. powerhouse of the cell; produces energy (atp) from food.
m. contains genetic material (dna); controls cell activities.
n. makes ribosomes.
o. transports materials throughout the cell; can be rough or smooth.

Explanation:

1. Nucleus: It contains genetic material (DNA) and controls cell activities, so it matches with M.
2. Mitochondria: Known as the powerhouse of the cell, it produces energy (ATP) from food, so it matches with L.
3. Ribosomes: They are the site of protein synthesis, so they match with C.
4. Endoplasmic Reticulum (ER): Transports materials throughout the cell (can be rough or smooth), so it matches with O.
5. Golgi Apparatus: Modifies, sorts, and packages proteins for transport, so it matches with I.
6. Lysosomes: Contain enzymes that break down waste and worn - out cell parts, so they match with B.
7. Cell Membrane: Controls what enters and leaves the cell; provides protection and support, so it matches with A.
8. Cytoplasm: Jelly - like fluid where organelles are suspended, so it matches with D.
9. Chloroplasts (plants only): Converts sunlight into chemical energy (photosynthesis), so they match with G.
10. Vacuole: Stores water, nutrients, and waste products, so it matches with F.
11. Cell Wall (plants only): Provides structure and protection for plant cells; made of cellulose, so it matches with J.
12. Nucleolus: Makes ribosomes, so it matches with N.
13. Cilia: Short hairs, provide movement, so they match with K.
14. Flagella: Tail - like, provides movement, so they match with E.
15. Centrioles (animals only): Organizes cell division in animal cells, so they match with H.
