The best answer is b - it is rigid.
The cell wall is defined as the rigid, outermost layer found in plants and also certain bacteria, algae and fungi. It is absent in animal cells.
The plant cell wall is made up cellulose which is a structural carbohydrate. The cell wall is rigid and thus offers structural support allowing plant such as trees to grow to great heights.
It also helps prevent water loss, helps protect against insects and pathogens and keeps the shape of the plant.
This question is asking for the number of ATP that is produced by the citric acid cycle and the electron transport chain.
Citrate is the first biological substance in the citric acid cycle and it is the starting point of the cycle. From one molecule of citrate, the citric acid cycle will produce 2 ATP while the electron transport chain will produce 34 ATP. Therefore, together both the citric acid cycle and the electron transport chain will produce 36 ATP.
