Organelle in Red Blood Cell are cytoplasm, cell membrane.
2. Chloroplast-The most important characteristic of plants is their ability to photosynthesize, in effect, to make their own food by converting light energy into chemical energy. This process is carried out in specialized organelles called chloroplasts.
3. Endoplasmic recticulum-manufactures, processes, and transports chemical compounds for use inside and outside of the cell.
4. Golgi Apparatus-is the distribution and shipping department for the cell's chemical products. It modifies proteins and fats built in the endoplasmic reticulum and prepares them for export as outside of the cell.
5. Mitochondria-breaks down carbohydrate and sugar molecules to provide energy, particularly when light isn't available for the chloroplasts to produce energy.
6. Nucleus- Controls all activities in the cell.
7. Cell membrane-Controls the movement of substances into and out of the cell.
8. Vacuole-Each plant cell has a large, single vacuole that stores compounds, helps in plant growth, and plays an important structural role for the plant.
They have a large surface area, relative to the other cells, that helps them absorb water and minerals more efficiently.
Organelles present in the muscle cell: Mitochondria, Myofibrils, Nucleus, Golgi Apparatus, Endoplasmic Reticulum.
Functions: Release energy and initiate movement.
The purpose of muscle is to regulate/initiate movement (using Adenosine triphosphate aka. ATP), they have larger mitochondria's so to produce a larger quantity of ATP. To completely oxidize carbohydrates an organelle called Mitochondria is required and so muscle cells have many of these.

Area of focus:
a. What are the organelles found in the cell?
b. What are the functions of these organelles?
c. Why are these functions of the organelles important to the living cell?
