Thylakoid membranes of chloroplasts resemble those of cyanobacteria because chloroplasts are believed to have evolved from endosymbiotic cyanobacteria. During evolution, the cyanobacteria that were engulfed by a host cell eventually became mutually beneficial, leading to the development of chloroplasts. The structural similarity between the thylakoid membranes of chloroplasts and cyanobacteria is a remnant of this evolutionary relationship.

What is the description of a chloroplast?
Chloroplasts occur in a variety of shapes and sizes, such as corkscrewlike ribbons or bracelet-shapes found in certain green algae. The chloroplasts of higher plants, however, tend to be shaped somewhat like two frisbees glued together along their edges, and when they are sliced in median section they resemble the outline of a football. Chloroplasts may be from 2 to 10 micrometers in diameter, and each is bounded by an envelope consisting of two delicate unit membranes . The outer membrane apparently is derived from endoplasmic reticulum whereas the inner membrane is believed to have orginated from the cell membrane of a blue-green bacterium. Within is a colorless, fluid, enzyme-containing matrix, called the stroma. Grana (singular: granum), which are stacks of coin-shaped double membranes called thylakoids are suspended in the stroma. The membranes of the thylakoids contain green chlorophyll and other pigments. Theses "coin-stacks" of grana, are vital to life as we know it on our planet today, for it is within the thylakoids that the first steps of the all-important process of photosynthesis occurs.
What are the main difference between mitochondrial and chloroplast DNA's?
The ribosomes of chloroplasts closely resemble bacterial ribosomes, while mitochondrial ribosomes show both similarities and differences that make their origin more difficult to trace.
What is the structure and functions the rough ER?
Rough endoplasmic reticulum is called rough because they contain ribosomes. It also contains many connected membranes, which resemble folded ribbons.
Are protists microrganisms?
Generally they are, but some plant like protists such as Rhodophyta and Chlorophyta are large multicelled protist seaweeds that closely resemble plants. Instead of roots they have holdfasts that anchor them to the sea floor, instead of stems they have stipes and instead of leaves they have blades that hold chloroplasts for photosynthetic purposes.
The chloroplasts in eukaryotes closely resemble?
The chloroplasts in eukaryotes closely resemble cyanobacteria, as first noted by French scientist Andreas Schimper. Cyanobacteria are bacteria that produce energy for themselves through photosynthesis.
Proteinoid microspheres are tiny bubbles that resemble cells because they?
Have selectively preameable membranes
What is the process when bone forms directly within mesenchyme arranged in sheetlike layers that resemble membranes?
Intramembranous ossification process
Do paramecium use chlorophyll?
Plants and algae cells have chloroplasts, photosynthesis is conducted in chloroplasts. Paramecium do not photosynthesize they get their food from the water they live in. So they do not need chloroplasts.

What is the function of the chloro plast?
The chloroplast is a fundamental organelle found in plants, acting as the mother, if you will, providing food to her children. One could argue that without chloroplasts, there would be no life; this fundamental organelle is vital for the process of photosynthesis to occur. Chloroplasts, in conjunction with chlorophyll, give plants their green color. They consist of 3 membranes, the intermembrane space, outer membrane, and the thylakoids. The inside of the chloroplast has fluid called stroma that contains small circular molecules of DNA as well as ribosome's. Stacks of thyakloids also found in the stroma, resemble a pile of CD's called and are called grana. Inside of the thyakloids contain chlorophylls and carotenoids which are the molecules that capture the sun light needed for photosynthesis.
