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

User Avatar

Asked by Wiki User

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.

Asked by Wiki User

Grana are stacks of thylakoids in chloroplasts where the light-dependent reactions of photosynthesis occur.

What is cell Chloroplasts used for?

User Avatar

Asked by Emy85

Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts contain chlorophyll, a pigment that absorbs light and allows the plant to produce glucose from carbon dioxide and water. This process is essential for plant growth and survival.

Does Chloroplast contain DNA in Eukaryotic Cells?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

A good cell analogy using chloroplasts is a solar panel on a house. Just like chloroplasts in a plant cell capture sunlight to produce energy for the cell through photosynthesis, solar panels capture sunlight to generate electricity for a house. Both structures are specialized to harness energy from their environment for the benefit of the larger system.

What is the function of a stroma in a leaf?

User Avatar

Asked by Wiki User

The stroma in a leaf is the region where the Calvin cycle takes place, which is a series of biochemical reactions that occur during photosynthesis. It is involved in the conversion of carbon dioxide into glucose, utilizing energy from sunlight and enzymes to drive the process.

What energy transformations take place in the chloroplast?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

Plant cells need chloroplasts for photosynthesis, a process that converts sunlight into energy. The vacuole helps maintain turgor pressure, supports the cell structure, stores nutrients and waste, and can also regulate pH levels in the cell. Both organelles are essential for the survival and functioning of plant cells.

Is chloroplast a living structure?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

No, yeast do not have chloroplasts. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, but yeast are single-celled fungi that do not perform photosynthesis.

Which takes place inside the chloroplast?

What are the functions of chloroplast and mitocondria?

User Avatar

Asked by Wiki User

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy by producing glucose. Mitochondria are the powerhouse of the cell, generating ATP through cellular respiration, breaking down glucose to produce energy for the cell.

Is chloroplast an organ?

User Avatar

Asked by Wiki User

No, a chloroplast is not an organ. It is a specialized organelle found in plant and algae cells that is responsible for photosynthesis, the process of converting light energy into chemical energy to produce sugars. Organs are made up of tissues and perform specific functions within an organism's body.

Some unicellular organisms are motile and some are nonmotile which cellular structures are associated with movement a flagella b chloroplast vacuoles d ribosomes?

User Avatar

Asked by Wiki User

A) flagella are cellular structures associated with movement in unicellular organisms. They are long, whip-like structures that help propel the organism through its environment. Vacuoles are membrane-bound sacs that store materials and assist with cell structure and shape. Ribosomes are involved in protein synthesis. Chloroplasts are organelles involved in photosynthesis and are typically found in plant cells.
