As plants grow, stems and branches thicken or increase in girth. this thickening is a result of cells in the vascular cambium. vascular cambium can develop into either xylem or phloem tissue within a plant. because of this unique ability, we would expect vascular cambium cells to have all but one of these characteristics. a) relatively undifferentiated b) simple, typical plant cells c) woody, re-inforced cell walls d) able to undergo cellular division

The correct answer option is C) woody, re-inforced cell walls.

Explanation:

When plants grow, its stems and branches thicken due to the cells in the vascular cambium. This vascular cambium can develop into either xylem or phloem tissue within a plant.

So from the given options, woody, re-inforced cell walls is that one characteristic that we would not expect vascular cambium to have.

Rather the cambium is expected to be simple, having undifferentiated cells that are capable of undergoing rapid cell division.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
