Answer 51:
Answer 50:
Option a) is correct i.e, allow the passage of cytosol and small solutes between cells.
Plasmodesmata in plant cells and the gap junctions in animal cells are structurally different but have the same function. Plasmodesmata are small channels present in the cell wall of a plant cell whereas the gap junctions are channels present along the cell membrane of an animal cell. Through these channels, cytosol, ions, small solute particles, nutrients and other substances pass back and forth when needed and the adjacent cells are connected. This is mode of cell to cell communication process.
Answer 49:
Option c) is correct i.e; cytoskeleton fibres
One of the major functions of cytoskeleton is movement such as vescicle movement, muscle contraction or even the cilia and flagella movement. Cytoskeleton consists of microfilament which is the main component responsible for muscle contraction and movement. Microfilaments are made up of protein molecules such as actin. Myosin are also an important component of muscle cells. These two components actin and myosin together help in the function of movement.
