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

Draw a chloroplast and label the following stormaenvelopegranumthylakoid.?
I'm unable to draw images. However, I can describe the structure of a chloroplast for you. A chloroplast consists of an inner and outer membrane that encloses a fluid called the stroma. Within the stroma, a network of interconnected membrane sacs called thylakoids are present. These thylakoids are stacked into structures called grana, which contain chlorophyll pigment molecules that are essential for photosynthesis.
What does chloroplasts perform?
Plants need lots of light to stay healthy. The reason for this is that there are millions of cells coating the leaves and stems, which need a certain amount of light to stay alive. The light from the sun is stored in the cells as energy or food.
Inside a plant cell, there are tiny structures called chloroplasts. They are the structures that provide the cell with energy. Chloroplasts are organelles (structures within cells) that trap light energy and convert it into chemical energy, which is then stored in the cell.
The process is called photosynthesis, and involves synthesizing (building) sugar molecules from the inorganic compounds carbon dioxide (CO2) and water (H2O).
Within chloroplasts there are membranes in which are embedded molecules of chlorophyll, which is essential for the trapping of light energy.
Chloroplasts have their own DNA, with more than 80 genes, and are believed to be descendants of ancestral free-living prokaryotes, which formed an endosymbiotic relationship with larger cells.
Chloroplasts are found in all types of plants and algae.
More detail of their responsibility:Chloroplasts are responsible for the green color of almost all plants and are lacking only in plants that do not make their own food, such as fungi and non-green parasitic or saprophytic higher plants. The chloroplast is generally flattened and lens shaped and consists of a body, or stroma, in which are embedded from a few to as many as 50 submicroscopic bodies (the grana) made up of stacked, disk-like plates. The chloroplast contains chlorophyll pigments, as well as yellow and orange carotenoid pigments. Chloroplasts are thus the central site of the photosynthetic process in plants. The chloroplasts of algae are simpler than those of higher plants and may contain special, often conspicuous, starch-accumulating structures called pyrenoids.
CHLOROPLASTS ARE IMPORTANT FOR PHOTOSYNTHESIS. THEY CONSIST OF THYLAKOIDS WHICH INTURN CONTAIN CHLOROPHYLL WHICH ABSORB LIGHT AND CARRY PHOTOSYNTHESIS
Chloroplast's are the organelle in which photosynthesis
takes place. Photosynthesis is the chemical process in which sugar is made using water and the sun's energy. Basically without getting into all the main details chloroplasts capture energy and converts it into food that the cell can use.
Do chloroplasts move in elodea cells?
Today I just did a lab viewing elodea cells and human cheek cells. When I viewed the Elodea cells on the highest power, I saw chloroplasts moving. They looked like tiny green spheres moving in little groups of two or more on a set of "tracks". I hope this answers the question.
Why doesn't the onion bulb contain chloroplast?
Because onion bulb develops underground and it is meant for food storage to overcome adverse environmental conditions. The skin of the bulb need not loose water and take part in gaseous exchange. Therefore, it does not have guard cells and stomata.
Does human blood cells have chloroplast?
Human does not have chloroplast. Chloroplasts are only found in plant cells.
Would you expect a plant's roots or leaves to have more chloroplasts?
Chloroplasts need sunlight for its function. So leaves have more chloroplasts
How does chloroplast process oxygen?
It takes carbon dioxide(CO2) from the air and water(H2O) from its roots into the chloroplast. Then the thylakoids inside the chloroplast attract sunlight energy which starts a reaction in which the CO2 molecules drop their carbon atoms leaving them with only O2(oxygen) and the remaining carbon atoms form different carbohydrates which are then converted into sacchrides like glucose.
How do plant cells need both chloroplasts and mitochondria?
Chloroplasts are for photosynthesis.Mitochondria are for respiration.
Where is most of the chlorophyll located in the plant?
The uppermost surface of a plant's leaves is where most chloroplasts are located, because that is where the sunlight will shine on them.
Why do chloroplasts have a range of pigments?
Different pigments respond to different wavelengths of visible light.
What helps chloroplast to do its job?
Chloroplasts are organelles that contain pigments used in photosynthesis.Chloroplasts absorb light and use it in conjunction with water and carbon dioxide to produce sugars.
it helps in absorbing solar energy to prepare food (photosynthesis)
The thylakoid membrane is highly folded to allow for many photosynthetic reactions to occur at once (much like the mitochondria).
Which region contain greatest number of chloroplast in a plant?
The region of a dicot leaf where most of the chlosoplast is found is in the palisade mesophyll because this is where the sunlight gets trapped so most the chlorophyll need to be present here so that photosynthesis can occur.
What would happen to an animal with chloroplast in its cells?
Plastids are only found in plant cells. They are a part of the photosynthesis process. They are not found in the cells of animals.
What is the function of chloroplast found in the cells of plants leaves?
The function of chloroplasts in leaves are to capture the light's energy for use in photosynthesis. For further information, access this web page:

How are chlorophyll and chloroplasts related and where are found?
Chloroplasts make the energy in sugar form by using photosynthesis and the product that come out is C_6H_12O_6 with the by product of O_2 and then the sugar is transported to mitochondria which then uses sugar to make ATP, which is the energy that our cells need to use in order to make protein.
Why is chloroplasts found mostly in leaves of plants?
Leaves get sunlight well. They are adopted for this
Would you expect to find chloroplasts in a liver cell?
no, unless it gets exposed to the sun in which case it will start growing and develop chloroplasts
The presence of a double membrane in chloroplasts, similar to that in prokaryotic cells, is a characteristic that suggests they may have evolved from free-living bacteria. Additionally, chloroplasts contain their own circular DNA, similar to bacteria, and replicate independently within the cell.
Which process ocurs in the chloroplast of plant cells?
Chloroplasts are found only in plant cells. They are the organelles primarily responsible for photosynthesis, the conversion of light energy to chemical energy as fuel for the plant.
What is stored in chloroplast?
magtanong nalang kayo sa mga matatalinong bobo sa cabiao
na sila:
mary anne moral at tricia parungao..
ang mga katanungan niyo ay masusulusyunan
hahahahaha!
crush you carl ♥and laurean ♥What part of the HUMAN BODY collects sunlight?
No there is no such part. Human are not photosynthetic
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.
