Chloroplasts
Chloroplasts are a part of a plant's cell. They capture energy from light.

Why is chloroplast so important to plant cells?
If there werd no chloroplasts, there would have no photosynthesis and if there were no photosynthsis there would't have life for plants to make food to survive.
Why don't spongy cells have as many chloroplasts?
Because it contains air spaces that help regulate gas exchange in leaves.
How does mitocondra and chloroplast work to gether?
Since the mitochondrial produces Carbon dioxide and water the chloroplast takes those products and makes sugar and oxygen, which those two products are taken by the mitochondrial to produce its products.
This diagram will clarify more:
Chloroplast gives=sugar+oxygen
Sugar+oxygen goes to mitochondrial
Mitochondriall gives= carbon dioxide +water
Carbon + water goes to chloroplast
Is a green pigment found in plant cells is called?
Chlorophyll is the green pigment in plants. Chlorophyll is found in cyanobacteria and it is found in the chloroplasts of plants and algae.
Why are chloroplasts not ordinarily visible in an unstained onion cell?
1. Because the chloroplasts that actually photosynthesize are found in the tops of the onions - the part that is actually above ground. There's no reason for there to be chlorophyll in the onion skin itself because these grow underground
How many times is chloroplast larger than mitochondria?
This is a relatively complicated question as the exact origins of mitochondria and how they came to be included in eukaryotic cells is still under investigation and therefore open to debate.
Everyone seems to agree though, that they originally come from bacterium and that they were assimilated into eukaryotic cells either because they were useful or through some form of symbiosis.
As mitochondria are common to both plant and animal cells it could therefore be argued that they shared a common ancestor at some point in evolution.
The inclusion of the chloroplast came later, and a separate line of mitochondrial and chloroplast carrying cells evolved - eventually becoming plants. The line without the chloroplast becoming animals.
Is a chloroplast unique to plant cells?
No, chloroplast is not a unicellular organism because it is not an organism. It is an organelle that can be found in unicellular or multicellular organisms.
How does fungi survive without a chloroplast?
Animal cells doesn't need any Chloroplast to live because all the nutritions, Protins,Oxygen and other substance are carried by blood.So, Like plant cells animal cell don't need any chloroplast to survive
Why do leaves contain more chloroplasts than roots?
Plant leaves contain more chloroplasts than plant roots because photosynthesis occurs in the leaves. In order to carry out the various functions of photosynthesis, a large number of chloroplasts is required.
Why does chloroplast look green?
Plants apear green because of chlorophyll--the pigment inside the chloroplasts. It absorbs red and blue light from the sun and uses this light to carry out photosynthesis within the plant.
What do you call the space between the thylakoids and the inner membrane of the chloroplast?
They are called thylakoid membranes.Light reaction takes place on them.
Characteristics of a chloroplast?
Chloroplasts are membrane-bound organelles found in plant cells that are responsible for photosynthesis. They contain chlorophyll, a green pigment that captures sunlight for energy production. Inside chloroplasts, thylakoid membranes are organized into stacks called grana, where light-dependent reactions occur. Chloroplasts also contain their own DNA and ribosomes, allowing them to produce some of their own proteins.
Does xylem cells have chloroplasts?
at first they do, but as they mature, their cell walls thicken and they get htese things called lignin that makes it harder and rigid. this help keep plant standing up, but also means water can't get into the xylem cells so they die, thus no nucelus.
What is a flattened sac in a chloroplast called?
The flatted sacks with in the chloroplasts are called chlorophyll. The chlorophyll preform photosynthesis inside the plant cell.
How is the inner membrane of a chloroplast different from the outer membrane?
A highly speacialised that transports protein
Are there chloroplasts in cyanobacteria?
Yes cynobacteri have photosynthetic mechanism. Cyanobacteria have an elaborate and highly organized system of internal membranes which function in photosynthesis. Photosynthesis in cyanobacteria generally uses water as an electron donor and produces oxygen as a by-product, though some may also use hydrogen sulfide as occurs among other photosynthetic bacteria. Carbon dioxide is reduced to form carbohydrates via the Calvin cycle. In most forms the photosynthetic machinery is embedded into folds of the cell membrane, called thylakoids. The large amounts of oxygen in the atmosphere are considered to have been first created by the activities of ancient cyanobacteria. Due to their ability to fix nitrogen in aerobic conditions they are often found as symbionts with a number of other groups of organisms such as fungi (lichens), corals, pteridophytes (Azolla), angiosperms (Gunnera) etc.
What is the function of the substance inside the chloroplast?
The substance is chlorophyll. They carry out photosynthesis
What ts the primary colour in chloroplast?
Not the primary color,it is primary pigment.Primary pigment is chlorophyll.
What are the green structures in plant cells that contains the green pigment chlorophyll?
They are called chloroplasts.They directs the photosynthesis.
Which part of a plant do chloroplast reside in?
PS1 (Photosystem 1) is located on the stroma thylakoids: the thylakoids floating around in the stroma. PS2 is located on the grana thylakoids, those thylakoids organized into stacks called grana!
Why is temperature important for photosynthesis?
temperature effects the rate at which photosynthesis works. e.g. if it is hot then the rate will increase, cold temperature will result in a less productive plant.
NOTE: The ideal temperatures vary from plant to plant.
Why animal cells do not contain chloroplasts?
Animal cells are not capable of photosynthesis hence these cells lack chloroplasts. We can also put it this way, that since animal cells lack chloroplasts, these are not capable of photosynthesis.
How does carbon dioxide and water reach the chloroplast in leaves?
The chloroplasts in the leaves absorb the light directly from the sun. The carbon dioxide goes into the leaves through the stomata (tiny holes on the bottom of a leaf) and is diffused through the rest of the cells. The water is absorbed by the roots then carried by the xylem up to the leaf and the cells in the leaf.
