a. Nucleus
Function: Contains the cell’s genetic material (DNA) and controls cellular activities by regulating gene expression.
Found in: Both plant and animal cells.

b. Rough Endoplasmic Reticulum (RER)
Function: Synthesizes and processes proteins, which are often transported to the Golgi apparatus.
Found in: Both plant and animal cells.
c. Smooth Endoplasmic Reticulum (SER)

Function: Synthesizes lipids, metabolizes carbohydrates, detoxifies drugs and poisons, and stores calcium ions.
Found in: Both plant and animal cells.

d. Golgi Apparatus
Function: Modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
Found in: Both plant and animal cells.

e. Mitochondria

Function: Produces ATP through cellular respiration, providing energy for the cell.
Found in: Both plant and animal cells.

f. Chloroplast
Function: Conducts photosynthesis, converting light energy into chemical energy stored in glucose.
Found in: Plant cells only.

g. Cell Wall
Function: Provides structural support and protection; maintains cell shape.
Found in: Plant cells (and some fungi and bacteria), but not in animal cells.

h. Ribosome
Function: Synthesizes proteins by translating messenger RNA (mRNA).
Found in: Both plant and animal cells.

i. Large Central Vacuole
Function: Stores nutrients and waste products, helps maintain turgor pressure, and contributes to cell growth.
Found in: Plant cells primarily (animal cells have smaller vacuoles).

j. Lysosome
Function: Contains digestive enzymes to break down waste materials and cellular debris.
Found in: Animal cells primarily (plant cells have similar structures called lytic vacuoles).

I hope this helps! Let me know if you have any more questions.
