Question

The cells are connected by Plasmodesmata, the system is .....
A. Apoplast
B. Symplast
C. Cross-connection
D. Plastidome

Answer 1

Hint: Plasmodesmata is the connecting system between two cells in which a channel-like connection formed between the cytoplasm of two cells, in this way both the cells are connected with each other. It is mainly present in bacteria cells.

Complete answer: 1. The apoplast is present in the plant cells and it is the empty space outside the cell membrane with which material like water can diffuse easily, it is clearly represented by the Casparian strips inside the root cells of the plant for conduction of the water molecules.
2. Symplast present inside the cell membrane of the cell, water, and other molecules that have low molecular weight can pass through the plasmodesmata from one cell to another cell without the use of any energy in this process.
3. Symplast is opposite to that of the apoplast, it is one of the processes which support the flow of water from the roots of the plants. Here symplast uses the plasmodesmata for the transport of water and other small molecular weight molecules.

So, the correct answer is “Option B”.

Note: The plastids of the cell are collectively known as the plastic dome, it is a membrane-bound cell organelle that plays an important role in the process of photosynthesis as the chlorophyll pigment present in these plastids.
It is present in plant cells, some algae, and in some strains of the cyanobacteria which undergo endosymbiosis. It is present in only those organisms who prepare their own food.
