By Catherine Beyer. The ankh is the most well known symbol to come out of ancient Egypt. In their hieroglyphic system of writing the ankh represents the concept of eternal life, and that is the general meaning of the symbol. Construction of the Image:
The outer layer of the double membrane is much more permeable than the inner layer, which features a number of embedded membrane transport proteins. Enclosed by the chloroplast membrane is the stroma, a semi-fluid material that contains dissolved enzymes and comprises most of the chloroplast's volume. Since, like mitochondria, chloroplasts possess their own genomes (DNA), the stroma contains chloroplast DNA and special ribosomes and RNAs as well.
A chloroplast is an organelle unique to plant cells that contains chlorophyll (which is what makes plants green) and is responsible for enabling photosynthesis to occur, so that plants can convert sunlight into chemical energy.nstructor: Jeremy Battista. A chloroplast is a basic organelle that in a sense is one of the most important organelles to us, and we don't even have them!! In this lesson, we will be looking where chloroplasts are found and what their role and function is in cells.
