The mitochondria
An organelle is a structure that is found within a cell and serves a specific function.
The pigment chlorophyll is contained within the organelle called the chloroplast.
A nucleolus
A chloroplast is an example of an organelle. Chloroplasts are found in plant cells.
The nucleus is an organelle. It is not found in an organelle.
Filamentous bacteria is sometimes found in the wastewater treatment system. This bacteria is seen as beneficial, but can be filtered to remove it from the water system.
Levels of organization of muscle ( in decreasing order)1. Muscle: Group of muscle fascicles, which work together to cause one specific movement.2. Fascicle: Bundle of muscle fibers3. Muscle fiber: Muscle cell: cylindrical cell of skeletal muscle. It has many nuclei, therefore it is called multinucleate.4. Myfibril: Contractile fibers found within a muscle cell. It has 100 - 1000's of muscle cells in each muscle fiber.5. Sarcomere: Structural and Functional unit of the muscle. It is the smallest unit of a muscle that is able to contract.6. Actin and myosin filaments: Filamentous proteins which can interact together to cause contraction.
Filamentous cytoskeleton is the cellular structure within the cytoplasm in every cell that helps it to keep its structure, protect the cell and allows cellular motion (using appendages like flagella, cilia, etc.). It also plays a role in intracellular transport and cellular division. The cytoskeleton is found in Eukaryotic and Prokaryotic cells.

Contained within a nucleus is DNA in the form of chromatin. In addition to this, the organelle known as a nucleolus is also found within the nucleus, and produces the building blocks of ribosomes.
