Cross-section of a leaf

Palisade cells are a type of leaf tissues and can be found within the mesophyll in leaves of dicotyledonous plants. They contain chloroplasts, which convert the energy stored in photons to chemical energy through photosynthesis. Image File history File links Question_book-3. ... Image File history File links Leaf_anatomy. ... Image File history File links Leaf_anatomy. ... Look up foliage in Wiktionary, the free dictionary. ... Biological tissue is a group of cells that perform a similar function. ... This article is about the leaf, a plant organ. ... Orders See text. ... Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. ... In modern physics the photon is the elementary particle responsible for electromagnetic phenomena. ... The leaf is the primary site of photosynthesis in plants. ...

Palisade cells show various adaptations: first, their cylindrical shape, which allows maximum absorption of light by chloroplasts. Second, these cells produce carbohydrates in greater quantities than are needed by each cell; these carbohydrates are fed into a wide variety of metabolic pathways and are vital to the functioning of the plant. Third, the palisade mesophyll contains the largest per-cell number of chloroplasts in the plant; usually positioned towards the upper surface of the leaf in order to harness the greatest amount of energy possible. Chloroplasts are organelles found in plant cells and eukaryotic algae which conduct photosynthesis. ... Carbohydrates (literally hydrates of carbon) are chemical compounds that act as the primary biological means of storing or consuming energy, other forms being fat and protein. ... In biochemistry, a metabolic pathway is a series of chemical reactions occurring within a cell, catalyzed by enzymes, and resulting in either the formation of a metabolic product to be used or stored by the cell (metabolic sink), or the initiation of another metabolic pathway (then called a flux generating...

Palisade cells are placed all over the top of a leaf, maximising the extent of light absorption. As a result, the top of a leaf is often darker than the bottom.

Re: What is a ciliated epithelial cell and a palisade cell? (218 words)
Epithelial cells are commonly arrayed in layers that are one cell thick.
The "sides" of the cells stick together to form the sheet while the remaining two surfaces are exposed to either the environment on the top or apical surface, and the bottom or basolateral surface.
Palisade cells are found in plants, particularly in the leaves.
