Every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all organelles. Some organelles are found only in some cell types.

This question is incomplete

Explanation:

However, as described in the question. each cell organelle has specialized function that assists the cell carry-out it's own function as a whole. Cell organelles include cell membrane, smooth and rough endoplasmic reticulum, vacuole, golgi complex, lysosomes, nucleus, mitochondria, chloroplasts among others.

Of these cell organelles, only three were mentioned in the question

Nucleus: This houses the chromosome which stores genetic material. This organelle is found in plant and animal eukaryotic cells. Indeed, eukaryotic organisms are sometimes described as organisms that have well defined nucleus.

Mitochondria: They are found in most plant and animal eukaryotic cells. They are usually referred to as the power house of the cell as they provide energy-rich chemical compounds (called ATP) for the cell's activities.

Chloroplasts: These are cellular structures/organelles that are found only in  green plants - they are cellular machinery for photosynthesis in plants. They also contain the green pigment called chlorophyll which is responsible for the green colour of green plants.

The type of the cell in which the organelles mentioned in the question are listed above.

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
