Chloroplasts

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

How do cells make more chloroplast?

Cells make more chloroplasts through a process called division. This involves the replication of chloroplast DNA and proteins, followed by the division of the organelle to create two separate chloroplasts. This allows the cell to increase its chloroplast population for photosynthesis.

Can chloroplast be compared to an organ in the human body?

Yes, chloroplasts can be compared to the human body's organ in terms of their function. Just like organs perform specific tasks within the body, chloroplasts are specialized organelles within plant cells that carry out photosynthesis, converting light energy into sugars for the plant's survival.

What part of the chloroplast do the storage of chemical energy in glucose molecules?

The storage of chemical energy in glucose molecules occurs in the stroma of the chloroplast. This is where the Calvin cycle takes place, converting carbon dioxide and light energy into glucose through a series of chemical reactions.

What is the term for the stacks of thylakoids found in chloroplasts?

The stacks of thylakoids found in chloroplasts are called grana. These structures are responsible for housing the light-absorbing pigments and protein complexes involved in the light-dependent reactions of photosynthesis.

What are stacks of thylakoids called?

granum are stacks of thylakoids.

grana are several stacks of thylakoids. :)

What is cell Chloroplasts used for?

chloroplast is inside a plant cell and is basically a feature in the cell that allows the plant to use photosynthesis and make its own food it also turns the plant green which is one of the many reasons why animal cells dont have them .

Does Chloroplast contain DNA in Eukaryotic Cells?

Yes, Chloroplast DNA is Totally Different from Nuclear DNA.

Mainly from the aspect of functioning, Chloroplast DNA translates for the proteins Needed to Synthesize Photosynthetic pigments and necessary photosynthetic accessories and photosynthetic enzymes,

whereas, Nuclear DNA is responsible for Coding Most of the Other Cellular and Extracellular Functional proteins.

Again, Nuclear DNA is mainly Linear in Shape, while, DNA found in Chloroplast are Circular.

There is Another point to be Stressed upon... The size...

Nuclear DNA is Much More Larger and heavier than Chloroplast DNA.

Finally a lame one-- Unlike the Chloroplast DNA, Nuclear DNA does not code for the proteins necessary for replication of Chloroplast... ;-)

Which part of chloroplast to the dark reaction occur?

The dark reaction, also known as the Calvin cycle, occurs in the stroma of the chloroplast. It does not require light to proceed and is responsible for capturing carbon dioxide and converting it into sugars through a series of enzymatic reactions.

What chloroplasts mean?

Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into energy. They contain chlorophyll, a green pigment that captures light energy for photosynthesis. Chloroplasts have their own DNA and are thought to have originated from ancient photosynthetic bacteria.

How does the internal structure with these organelles support mitochondria and chloroplast's function?

The internal structure of mitochondria and chloroplasts, with their highly folded inner membranes, increases surface area for more efficient energy production. This structure also allows for compartmentalization of specific metabolic processes, enabling enzymes and other molecules to be concentrated and organized for optimal function. Additionally, the presence of unique structures such as cristae in mitochondria and thylakoid membranes in chloroplasts play key roles in ATP production and photosynthesis, respectively.

What is a good cell analogy using chloroplast?

A chloroplast is like a "energy producing center," such as a power plant. To tie in with the "green" nature of chloroplasts, it could be considered a solar farm (which are used in the desert to capture the sun's energy and turn it into electricity for cities.)

Hope this helps!

What does chloroplast remind you of?

it remins me of plastic just the way the ending part is spelled.

What is the function of a stroma in a leaf?

The stoma is a pore in the leaf used for gas exchange. The stoma is formed by the guard cells. The guard cells are in charge of changing the size of the opening. Through these openings, the air that contains carbon dioxide enters the plant and is then used for photosynthesis and respiration.

In this process, water vapour will be released into the air from the pores. This is known as transpiration. Oxygen produced in the process photosynthesis, will exit from these openings.

What energy transformations take place in the chloroplast?

In the chloroplast, light energy is transformed into chemical energy during the process of photosynthesis. This chemical energy is stored in the form of glucose, which can be later used by the plant for cellular respiration to produce ATP for energy.

What parts of chloroplast store the chemical energy in glucose molecules?

The chemical energy in glucose molecules is stored in the bonds between the atoms within the glucose molecule itself. The process of photosynthesis in chloroplasts converts light energy into chemical energy, which is stored in the form of glucose molecules.

What is the function of stroma lamellae?

Stroma Lamallae is the holow tube-like channel that is paired with a stack of thylakoids (Granum). It transports nutients and substance needed for the thylakoids in order to keep tjhe organelle alive and functioning.

What happens to carbon dioxide and water in chloroplast?

In chloroplasts, carbon dioxide and water undergo photosynthesis to produce glucose and oxygen. This process is powered by sunlight and occurs in the presence of chlorophyll, a pigment in chloroplasts. The glucose produced is used as energy for the plant, while the oxygen is released as a byproduct.

Are there chloroplasts in subsidiary cells?

Subsidiary cells do not typically contain chloroplasts. Chloroplasts are found in the guard cells of plant stomata, where they play a role in regulating gas exchange. Subsidiary cells primarily function in supporting and assisting the guard cells in their role in controlling stomatal opening and closing.

Why are chloroplasts considered carbohydrate factories and ribosomes as protein factories?

Chloroplasts are considered carbohydrate factories because they use light energy to convert carbon dioxide from the air into carbohydrates through the process of photosynthesis. Ribosomes are considered protein factories because they are the cellular organelles responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.

What is the Process that occurs in chloroplasts is called what?

The process that occurs in chloroplasts is called photosynthesis. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose molecules, using carbon dioxide and water. This process is essential for the survival of most living organisms on Earth.

Why do plant cells need chloroplast and vacuoles?

A plant cell needs water to maintain it's shape. Unlike animal cells, plants cannot suffer hydrolysis, meaning plants cannot burst when they fill up with water. This is due to the cell wall, and plant cells instead experience turgor pressure. This creates the need for a large vacuole to hold the needed water. If the cell were to not have enough, the cell would atrophy (flatten) and become flaccid.

Is chloroplast a living structure?

Yes, chloroplasts are living structures found in plant cells. They are responsible for photosynthesis, converting sunlight into energy for the plant.

Do yeast have chloroplast?

No.Yeast are type of fungi.No fungi is photosynthetic
