The body of a tiger is made of many types of cells, such as muscle cells and nerve cells. All of the tiger’s cells are eukaryotic. What else is true about the tiger’s cells?
The Correct Answer and Explanation is:
Correct Answer:
They have a nucleus and membrane-bound organelles.
Explanation
The body of a tiger, like that of all animals, is composed entirely of eukaryotic cells. This means that each of the tiger’s cells shares certain structural characteristics that distinguish them from prokaryotic cells, such as those found in bacteria.
One of the most defining features of eukaryotic cells is the presence of a nucleus. The nucleus is a membrane-bound organelle that houses the cell’s genetic material (DNA). In the case of a tiger, its DNA contains the instructions necessary for producing proteins, regulating the body’s functions, and passing traits to offspring.
In addition to a nucleus, eukaryotic cells contain a variety of membrane-bound organelles, each of which performs specific functions that are essential for the cell’s survival and for the overall functioning of the organism. These include:
- Mitochondria, often called the “powerhouses” of the cell, which produce energy (ATP) through cellular respiration.
- Endoplasmic reticulum (ER), which helps in the synthesis of proteins (rough ER) and lipids (smooth ER).
- Golgi apparatus, which modifies, packages, and distributes proteins and lipids.
- Lysosomes, which contain digestive enzymes to break down waste materials and cellular debris.
Because a tiger is a multicellular organism, its cells are also specialized. That means different types of cells (like muscle cells, nerve cells, skin cells, etc.) have unique structures and functions, but all maintain the basic features of eukaryotic cells.
In summary, since all of a tiger’s cells are eukaryotic, they contain a nucleus and a variety of membrane-bound organelles. These internal structures enable the cells to carry out complex processes that support the life and activities of the tiger as a highly developed organism.
