Palisade cells contain a high concentration of chloroplasts, particularly in the upper portion of the cell, making them the primary site of photosynthesis in the leaves of plants that contain them. Their vacuole also aids in this function: it is large and central, pushing the chloroplasts to the edge of the cell, maximising the absorption of ...
Within the envelope membranes, in the region called the stroma, there is a system of interconnecting flattened membrane compartments, called the thylakoids.The thylakoid membrane is quite similar in lipid composition to the inner envelope membrane, containing 78% galactolipids, 15.5% phospholipids and 6.5% sulfolipids in spinach chloroplasts.

It is often found in the chloroplasts of C 4 plants, though it has also been found in some C 3 angiosperms, [23] and even some gymnosperms. [128] The chloroplast peripheral reticulum consists of a maze of membranous tubes and vesicles continuous with the inner chloroplast membrane that extends into the internal stromal fluid of the
In general, there are 4 main cellular compartments, they are: The nuclear compartment comprising the nucleus; The intercisternal space which comprises the space between the membranes of the endoplasmic reticulum (which is continuous with the nuclear envelope) Organelles (the mitochondrion in all eukaryotes and the plastid in phototrophic ...
The endoplasmic reticulum (ER) is a synthesis and transport organelle that branches into the cytoplasm in plant and animal cells. [3] The Golgi apparatus is a series of multiple compartments where molecules are packaged for delivery to other cell components or for secretion from the cell. [4]
An underexposure to light can cause the thylakoids to fail. This causes the chloroplasts to fail resulting to the death of the plant. Thylakoid formation requires the action of vesicle-inducing protein in plastids 1 (VIPP1). Plants cannot survive without this protein, and reduced VIPP1 levels lead to slower growth and paler plants with reduced ...

Chloroplasts are diverse in morphology and include many forms, including, cup-shaped (e.g. Chlamydomonas), or axial, or parietal and reticulate (e.g. Oedogonium). [2] In many species, there may be one or more storage bodies called pyrenoids (central proteinaceous body covered with a starch sheath) that are localised around the chloroplast. [5]
