Question

Is there any difference between a palisade cell and a palisade mesophyll? ?

Answer 1

Palisade mesophyll is composed of palisade cells.  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.

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.

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.

Palisade cells are grouped together to give the palisade layer of the leaf- this is the leaf tissue where most of the photosynthesis takes place.

Answer 2

No difference !

1 ) Palisade cell means a single Palisade cell from a Palisade tissue . Or from a group of palisade cells .

2 ) Palisade mesophyll means Mesophyll ( Middle part of a cross section of a leaf ) which is full of or partly made up of Palisade tissue .

Pictures on the link . click on them and see --

1 ) A single Palisade cell is on the links below -

2 ) Palisade tissue on the link below ( It is a part of Mesophyll )--

EDIT - It will be interesting and not out of place to know how the word " Palisade" came to be used for this tissue / cell /

The dictionary meaning of Palisade is --

i)A fence of poles forming a defense barrier or fortification.

ii)One of the poles of such a fence.

The picture of such a fence is -

The Photosynthetic cells or the tissue in the leaf looks like this palisade so they are called that way .

Answer 3

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.

So the answer is no, they are one in the same...
