What does palisades mean? A row of cliffs in northeast New Jersey along the western bank of the Hudson River. Much of the area is parkland Definition of Hydrophytes. Hydrophytes refer to the aquatic plant bodies that live freely, entirely or partially submerged in different aqueous environments. They are the plant bodies that adapt themselves to survive in an aquatic ecosystem by modifying their leaves, stems and roots due to the modifications in their cellular components Photosynthesis takes place in the cells of the mesophyll layer, especially the palisade mesophyll. Leaves are thin and have a large surface area, to speed up the supply of carbon dioxide to the palisade cells and to maximise the amount of sunlight that hits the leaf and can be absorbed by chlorophyll Vascular Tissue Definition. Vascular tissue is an arrangement of multiple cell types in vascular plants which allows for the transport of water, minerals, and products of photosynthesis to be transported throughout the plant. Non-vascular plants, such as some algae and moss, do not have vascular tissue and therefore cannot easily transport water and nutrients The key difference between palisade parenchyma and spongy parenchyma is that palisade parenchyma consists of columnar cells which are compacted tightly below the upper epidermis of a leaf while spongy parenchyma consists of rounded cells which are loosely arranged below the palisade parenchyma.. Leaves are the main structural parts of plants that produce food by photosynthesis
