Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Movement of water through the cytoplasm and plasmodesmata in the root, is known as the:
A
apoplastic pathway
B
symplastic pathway
C
cellular pathway
D
vacuolar pathway
Explanation: 

Detailed explanation-1: -The symplastic pathway: It provides the movement of water from one cell to another cell by plasmodesmata. Symplast is the inner side of the plasma membrane.

Detailed explanation-2: -The symplast is the pathway in which the water molecules moves through the plasmodesmata region in the cells. The symplast is the living region present between two cells which connects one cell with the other. The apoplast pathway is the path in which the water is moving between the intercellular spaces.

Detailed explanation-3: -Plasmodesmata connect neighbouring cells throughout a plant to establish the symplast. Plasmodesmata establish an interconnected cytoplasm called the symplast, through which metabolites, proteins, and RNAs are exchanged between cells, tissues, and organs.

Detailed explanation-4: -cytoplasmic streaming, also called protoplasmic streaming, the movement of the fluid substance (cytoplasm) within a plant or animal cell. The motion transports nutrients, proteins, and organelles within cells.

Detailed explanation-5: -In symplast pathway, water passes from cell to cell through their protoplasm. It does not enter cell vacuoles. The cytoplasm of the adjacent cells are connected through plasmodesmata. Symplastic movement is aided by cytoplasmic streaming of individual cells.
