The chloroplast was discovered in Mereschkowsky in 1905. He stated that chloroplasts are similar to mitochondria but chloroplasts are found only in plants and protista.
The chloroplast is surrounded by a double-layered membrane that is involved in energy metabolism. Chloroplasts have a few important parts such as the Stroma, which is the dense fluid within the chloroplast and is the site of conversion of carbon dioxide to sugar, the thylakoid which is the flattened sac-like membrane structures in the chloroplasts. This is the site of conversion of light energy to chemical energy.
Grana is the dense layered stacks of thylakoid sacs. The grana is the site of the conversion of light energy to chemical energy.
Starch is sometimes stored in the chloroplasts.
Chloroplasts are necessary for photosynthesis.
Plants are the main organisms that use photosynthesis to make their food.
In photosynthesis, solar energy is converted to chemical energy.
What else can I help you with?
What are common in plants but not in animals?
Cell walls, chloroplasts, and the ability to photosynthesize are common in plants but not in animals. These features are unique to the plant kingdom and are key for plant structure, function, and energy production.
What are 3 distinguishing features of euglenophytes?
Three distinguishing features of euglenophytes are the presence of a pellicle (proteinaceous layer), two flagella for locomotion, and the ability to photosynthesize with chloroplasts derived from green algae through secondary endosymbiosis.
Do nitrogen fixing bacteria have chloroplasts?
No bacteria have chloroplasts. Plants have chloroplasts. Chloroplasts were originally cyanobacteria -- they are the results of an endosymbiosis between a cyanobacterium and a eukaryote.
Which part is only found in plant cells?
A cell wall made of cellulose, hemicellulose and pectin is one of the unique features of plant cells. They also contain chloroplasts, which are photosynthetic organelles (that are not found in animal cells).
What plant cell features are not present in animal cells?
Plant cells have cell walls, chloroplasts for photosynthesis, and large central vacuoles which are not present in animal cells. Additionally, some plant cells may have plastids for storage of starch and pigments.
What are two features plant sells have that animals do not?
chloroplasts
What are the features of a cell?
chloroplasts, cell wall, permanent vacuole, cell membrane
What features indicate that a cell is a plant cell and not an animal cell?
lack of a cell wall and chloroplasts and the presence of centrioles
What does a plant cell have that a amnimal cell not have?
The three features that a plant cell has that an animal cell does not have are cell wall, chloroplasts and vacule

Two principal organelles of eukaryotes that share features with one another and with bacteria from which they apparently were derived are the?
Two principal organelles of eukaryotes that share features with one another and with bacteria are the mitochondria and chloroplasts. Both organelles have their own DNA and ribosomes, similar to bacteria, and are thought to have originated from ancient endosymbiotic bacteria that were engulfed by early eukaryotic cells.
What are 3 distinguishing features of euglenophytes?
Three distinguishing features of euglenophytes are the presence of a pellicle (proteinaceous layer), two flagella for locomotion, and the ability to photosynthesize with chloroplasts derived from green algae through secondary endosymbiosis.
What two organelles are derived from symbiotic bacteria?
Chloroplasts and mitochondria. It is believed they were engulfed by the cells because of the dual membrane present on both. Both are believed to have originated from an endosymbiotic bacteria. Mitochondria's inner matrices contain DNA, and they have many features similar to those of bacteria. Chloroplasts are believed to have come from an endosymbiotic cyanobacteria.

Where is the thylakiod located in a cell?
The chloroplasts
