mitochondria and chloroplast

this is a picture of chloroplast- the little things that you see are called thykloids. i got this picture from course1.winona.edu/.../ Photosynthesis.htm























this is a picture of mitochondria. mitochondria the tan inner
membrane is called a cristae and the fluid on the inside is called the matrix

















Mitochondria are found in lots of different kinds of cells while Chloroplast is only found in plants. Mitochondria and chloroplast share the same similar structure features. They both have inner and outer membrane and their overall shapes are similar. While there inner membranes are slightly different Their purpose behind the designs are the same.

Chloroplast is the reason plants are called self feeders.
Photosynthesis is the process that the chloroplast uses energy from the sun to convert the carbon dioxide into energy rich sugar called glucose. The most important part of this complex reaction. The most important part (making the glucose) is made in the Granum, on these disks called thylakoid membranes.

Mitochondrion is often called the “power house” of a cell. It is here, on the inner membrane or the cristae that an important reaction happens. This reaction is called cellular respiration. The mitochondria harass the energy within the glucose to make a special energy molecule called ATP. ATP is like a battery. And is used to power all of the other activities within a cell.
