  1. Nucleus
  2. Nucleolus
  3. Cytoplasm
  4. Cell membrane (plasma membrane)
  5. Mitochondrion
  6. Golgi apparatus (Golgi body)
  7. Lysosome
  8. Endoplasmic Reticulum (Rough and Smooth)
  9. Ribosomes
  10. Centrioles

Explanation:

An animal cell is a eukaryotic cell that contains specialized structures called organelles, each with a specific function necessary for the cell’s survival and performance. The nucleus is the control center, housing DNA and directing cell activities. Within the nucleus is the nucleolus, where ribosomal RNA is produced.

The cytoplasm is a jelly-like substance that fills the cell and holds organelles in place. Surrounding the cell is the cell membrane, a selectively permeable barrier that regulates what enters and leaves the cell.

Mitochondria, often called the “powerhouse” of the cell, generate energy through cellular respiration. The endoplasmic reticulum (ER) comes in two forms: rough ER (with ribosomes, involved in protein synthesis) and smooth ER (involved in lipid synthesis and detoxification). Ribosomes, whether free-floating or on the rough ER, are the sites of protein synthesis.

The Golgi apparatus modifies, sorts, and packages proteins for delivery to different parts of the cell or for secretion outside the cell. Lysosomes contain digestive enzymes that break down waste materials, old cell parts, and invading pathogens.

Lastly, centrioles are involved in organizing microtubules during cell division.

Together, these structures work in harmony to maintain cellular function, growth, and reproduction. Understanding these organelles provides insight into how cells operate and how life functions at the microscopic level. The CELLS alive! interactive tools often help visualize these components, making the learning experience more engaging.
