SSC MTS EXAM

Detailed explanation-1: -Photosynthates, such as sucrose, are produced in the mesophyll cells (a type of parenchyma cell) of photosynthesizing leaves. Sugars are actively transported from source cells into the sieve-tube companion cells, which are associated with the sieve-tube elements in the vascular bundles.

Detailed explanation-2: -The plant’s phloem transports the dissolved sugars from the leaves and takes them to various storage sites throughout the plants, like roots or tubers, known as “sinks”. The phloem off-loads its sugary cargo to these sinks across cell membranes through a process known as active transport.

Detailed explanation-3: -Sugars are moved about the plant in a layer of cells called the phloem. Phloem is made up of living cells located just outside the cambium. The cambium produces the phloem in trunks, branches and roots.

Detailed explanation-4: -The sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. Phloem is composed of living cells that transport a water solution of sugars that we commonly call sap.
