Cambium is a kind of meristem which is most active in woody plants and it lies between the bark and wood of the stem. The vascular cambium forms tissues that carry water and nutrients throughout the plant. On the outer surface, the vascular cambium forms new layers of phloem, and on the inner surface, new layers of xylem. The cork cambium creates cells that eventually become bark on the outside and cells that add to the cortex on the inside. In woody plants, the cork cambium is part of the periderm. So, the correct answer is "both vascular and cork cambium".

Meristematic activity is seen the maximum in the shoot of a plant. The meristematic tissue contains undifferentiated cells found in the zone of the plant where growth can take place.

Intrafascicular cambium is present between xylem and phloem in dicot stem and roots. It is also termed as fascicular cambium. This meristematic area spreads laterally from each bundle and eventually becomes continuous, forming a complete vascular cambium.

The primary growth in plants results from promeristem. Promeristem is the early embryonic meristem from which other advanced meristems are derived. It is present in a very small area which further divides to form primary meristem.

Meristem cells are most likely to divide as it has the capability to divide but others do not have the capability to divide. Meristem cells are located in a specific region where the growth of the plant occurs. So, the correct answer is option "meristem".

To ensure strong and constitutive expression of a transferred gene across all tissues of a plant, the Cauliflower Mosaic Virus 35S (CaMV 35S) promoter is widely used because it drives high-level constitutive expression in almost all plant tissues.

In castor bean and pea, the cotyledons serve as the primary food storage organs for the developing embryo. Maize and soybean typically store food in the endosperm or other structures, making castor bean and pea the correct examples for cotyledonary food storage.
