The cell has several structures and organelles that help it perform its role in an organism.
1. Plasma membrane. This mediates cell to cell interactions and adhesion to surfaces.
2. Cytoplasmic matrix. This forms an environment for other organelles and is the location of many metabolic processes.
3. Nucleus. This is the repository for genetic information and is also the control center of the cell.
4. Mitochondria. This are used for energy production.
5. Golgi apparatus. These are used for packaging and secretion of materials for various purposes and for lysosome production.
6.Cell wall and Pellicle. Strengthen and give shape to the cell.

Explanation:
Many fish and wetland specie live in waters that run through farm land. Activities on the farm including pesticide use can affect fish and water quality. This is due to run-offs of rain water downstream or to ponds either due to rain water or irrigation. they drift and settle because of they d break down very slowly. In several months later, because of ingestion and fish being dependent of water for oxygen end up having concentration of pesticides in their system.
