Natural selection occur to give the best survival chance to the organisms. Hence, they bring about biological evolution through future generations thereby increasing the variety of living things. This survival reflects on their ability to produce more offspring. The offspring must continue to survive by competing with the resources found in nature.
Answer:
The correct answer will be- endoplasmic reticulum
Explanation:
Plasmodesmata are the cytoplasmic bridges spanning in the cell walls of the plant cell which link the cytoplasm of the adjacent cells. The plasmodesmata play an important role in the plants as they allow the inter-cellular connections between the cells.
The plasmodesmata are derived from the juxtaposed endoplasmic reticulum which forms the axial or the central portion of the plasmodesmata and allows the transport of molecules between two cells.
Thus, the endoplasmic reticulum is the correct answer.
