  2. Important facts about chloroplast • Chloroplasts are used for photosynthisis . • They have a double membrane around them. • The space inside is called the stroma. The space may contain starch grains and lipid bodies. • In the stroma are structures called thylakoids. • The thylakoids are stacked to form structures called grana. • The grana contain the pigment chlorophyll along with most secondary pigments.

  3. Structure of the Chloroplast • The are between the outer membrane and the inner membrane (thylakoid)which is also called stroma. • Stacks of thylakoids are called granum.

  4. Where is it located in the cell? • The Chloroplast is located in all animal cells. • Chloroplasts are specialized organelles found in all higher plant cells. These organelles contain the chlorophyll, hence provide the green color. They have a double outer membrane. In the stroma are other membrane structures - the thylakoids and grana.

  5. What does it do for the cell? • “Chloroplasts are the food producers of the cell. They are only found in plant cells. Animal cells do not have chloroplasts. Every green plant you see is working to convert the energy of the sun into sugars. Plants are the basis of all life on Earth. They create sugars, and result of that process is the oxygen that we breathe. That process happens in the chloroplast.”

  6. What kind of cells have this organelle? • Chloroplasts are found only in plant cells. They contain the green pigment called chlorophyll, which absorbs sunlight. The chloroplasts use the sunlight energy to make food for the plants. Cells in the top half of the leaf, called palisade cells, have many chloroplasts. Cells in the bottom half of the leaf, called spongy cells, have fewer chloroplasts. • Not all plant cells contain chloroplasts
