Detailed explanation-1: -Companion cells function to load and unload sugars into the cavity of sieve tube members.
Detailed explanation-2: -Companion cells are found along with sieve tube elements in the phloem. The main function of companion cells is to maintain pressure gradient in the sieve tube elements.
Detailed explanation-3: -The main functions of sieve tube members include maintaining cells and transporting necessary molecules with the help of companion cells. The sieve tube members are living cells (which do not contain a nucleus) that are responsible for transporting carbohydrates throughout the plant.
Detailed explanation-4: -Sieve tubes are a component of the phloem in plants. They function as the vessle that transports organic food and other material across the plant.
Detailed explanation-5: -Sieve tubes are responsible for the transport of food throughout the plant body while companion cells are responsible for regulating the activity of the sieve element.
