Chapter 24, Problem 44A

Interpretation Introduction

Interpretation: The names of the three organelles found in eukaryotic cells and their functions have been described.

Concept introduction: Eukaryotic cells include organelles that are bound by membranes. This kind of cell is found in both plants and animals.

Answer to Problem 44A

The three organelles of eukaryotic cells and their functions are as follows:

1. Nucleus: The nucleus contains DNA and directs the cell's activities.
2. Lysosomes: Lysosomes contain digestive enzymes capable of breaking down molecules.
3. Endoplasmic reticulum: The endoplasmic reticulum carries nutrients and other substances throughout the cell.

Explanation of Solution

Organelles are bounded by a membrane found inside eukaryotic cells, where they are responsible for carrying out specialized tasks that are essential to the cell's continued existence. The three organelles found in eukaryotic cells are the nucleus, the lysosomes, and the endoplasmic reticulum.

The functions that organelles found in eukaryotic cells perform are as follows:

1. Nucleus: The genetic material, DNA, is stored in the nucleus, and the nucleus is also responsible for directing the activities of the cell.
2. Lysosomes: Lysosomes are organelles containing digestive enzymes responsible for the breakdown of substances.
3. Endoplasmic reticulum: The endoplasmic reticulum (ER) is responsible for transporting various materials and nutrients throughout the cell.

Conclusion

The three organelles of eukaryotic cells and their functions are as follows:

1. Nucleus: The nucleus contains DNA and directs the cell's activities.
2. Lysosomes: Lysosomes contain digestive enzymes capable of breaking down molecules.
3. Endoplasmic reticulum: The endoplasmic reticulum carries nutrients and other substances throughout the cell.
