WebbPericycle cells can divide and give rise to lateral roots in both monocots and dicots. In dicots, the pericycle also generates meristem cells that support secondary root growth and the cambium that produces xylem and phloem. Parenchyma. Parenchyma cells are the most abundant ground tissue cells, making up the majority of the cortex of dicot roots. WebbPhloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant. The xylem and phloem always lie adjacent to each other in a vascular …
WebbPhloem is one of types of complex permanent tissue forming conductive or vascular system in plant body. It conducts the prepared food from leaves to storage organs and growing regions. It is composed of following four components sieve tubes, companion cells, phloem fibres and phloem parenchyma. Therefore, the correct answer is option D. WebbPlants create sugar in the mesophyll cells of their leaves by photosynthesis. This sugar, mostly sucrose, has to be loaded via the bundle sheath into the phloem vascular system (the sieve elements), where it is distributed to growing parts of the plant. We analyze the feasibility of a particular loading mechanism, active symplasmic
WebbPhloem is one of the two tissues that make up the plant's long-distance transport system, the other being xylem. Phloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored. Primary phloem originates from the procambial regions in meristems, while secondary phloem originates ...
