Chloroplasts
A typical plant cell (e.g., in the palisade layer of a leaf) might contain as many as 50 chloroplasts.

 


Chloroplasts
One of the most widely recognized and important characteristics of plants is their ability to conduct photosynthesis, in effect, to make their own food by converting light energy into chemical energy.

Chloroplasts - Show me the Green
Chloroplasts are the food producers of the cell. They are only found in plant cells and some protists. Animal cells do not have chloroplasts.

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis.

Chloroplasts contain several important membranes, vital for their function. Like mitochondria, chloroplasts have a double-membrane envelope, called the chloroplast envelope.

chloroplasts Disk-like organelles with a double membrane found in eukaryotic plant cells; contain thylakoids and are the site of photosynthesis. ATP is generated during photosynthesis by chemiosmosis. PICTURE ...

Chloroplasts and endosymbiosis
Like mitochondria, chloroplasts have their own DNA, termed cpDNA.

Chloroplasts
The diagram below illustrates how energy from sunlight is used for the energy requirements of cells.

Chloroplasts (plastids)
Surrounded by a double membrane, containing stacked thylakoid membranes. Responsible for photosynthesis, the trapping of light energy for the synthesis of sugars.

Chloroplasts also have double membrane but instead of having the inner one thrown into folds, there are stacks of disk shaped membranes where the light reactions of photosynthesis occur.

Chloroplasts and mitochondria are organelles within eukaryotic cells (cells of organisms other than bacteria, which do not have organelles). These organelles have their own genetic material.

Mitochondrial DNAMitochondria, and chloroplasts in plants, carry their own small chromosomes, usually in multiple copies per organelle. These carry a limited number of genes which code for rRNA, tRNA and a few organelle proteins.

The set of chromosomes in a cell and any other hereditary information found in the mitochondria, chloroplasts, or other locations is collectively known as its genome.

The circular, superhelical double-strand DNA of the chloroplasts. The structure is two inverted repeats separating one small single copy and one large single copy. This structure is very similar in most plants, the size varies between 120 and 160 kb.

Chloroplast (plant cells only): Chloroplasts are specialized organelles found in all higher plant cells. These organelles contain the plant cell's chlorophyll responsible for the plant's green color. Chloroplasts have a double outer membrane.

palisade chlorenchyma
the upper internal tissue of a plant leaf which are stacked side by side and contain chloroplasts for photosynthesis. The chloroplasts lie close to the edge of the cell in order to gain maximum light and gas supply.

Photosystem I In chloroplasts, a photosynthetic unit that includes a light-harvesting complex, a reaction center, and an electron-transport chain.

Proplastides develop to leukoplasts (or etioplasts in the absence of light) which develop to chloroplasts and/or chromoplasts. All types of plastides can transform into each other. Their shape and function differs.

Chlorophyll is a substance most commonly found in plants usually located in chloroplasts. Its primary function is to absorb sunlight for photosynthesis to occur within the plant.
