Monocots are flowering plants in which seeds contain only one cotyledon. WebbIn monocot vascular bundles the phloem is always oriented toward the outside of the plant and the xylem toward the inside. There is no cambium and no secondary growth. Around the outside of the vascular bundle is a layer of parenchyma cells called the bundle sheath. This layer of cells is very important in photosynthesis. WebbThese large, bubble-like cells, located just beneath the epidermis, are thought to help the leaf bend or fold. This is important because folding the leaf changes its exposure to light and the amount of water it retains.
