Question 1,2 & 3
1.Cell wall-protects the cell and regulates the life cycle of the plant organism.

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.
