How do you identify a chloroplast in a cell?
The chloroplast structure within a plant cell is composed of the following parts:
- Inner and outer membranes
- Stroma
- Thylakoid membrane which contains the photosystems
- Granum which is a stack of thylakoids
- Stroma lamellae which are flattened sacs inside the chloroplast
The inner membrane contains enzymes and proteins that are involved in photosynthesis while the outer membrane acts as a barrier that prevents the movement of large molecules. The stroma is the space between the inner and outer membranes and is filled with a variety of enzymes and proteins that are involved in metabolic processes. The thylakoid membrane contains the photosystems which are responsible for absorbing sunlight and converting it into chemical energy. The granum is a stack of thylakoids and the stroma lamellae are flattened sacs inside the chloroplast that contain enzymes and proteins involved in the production of carbohydrates.
What are the components of a chloroplast?
Chloroplasts consist of a double membrane, thylakoid membranes arranged in stacks called grana, stroma (fluid inside the chloroplast), and contain their own genetic material in the form of circular DNA.
What do producers containing chlorophyll do?
Producers contain chlorophyll. They are called producers because they can produce food from the energy of the sun. No other organism can do that. They all have to get their energy from a living or dead organism.
Scientists have recently discovered that there is some cross over of chlorophyll in simple marine animals that can steal chlorophyll from algae and incorporate it into their gut. An exciting discovery!
What are the advantages of having more chloroplast?
Having more chloroplasts allows for increased photosynthesis, leading to greater production of glucose and oxygen. This can result in enhanced growth and productivity in plants. Additionally, more chloroplasts provide a larger surface area for light absorption, optimizing the utilization of sunlight for energy.
Why is a grasshopper's blood green Grasshoppers have a circulating chlorophyll pigment.?
No it does not. Animals are not containing chloroplasts.
Where convert light reactions within the chloroplast?
Photosynthesis consists of light-dependent reactions and light-independent reactions. These light reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments are found.
How is a chloroplast similar to bacterium?
They are similar in size.Both have own circular DNA.They have 70s ribosomes.
Where is chlorophyll found in the plant cells?
The chlorophyll pigment is present in the mesophyll tissue. It is also found on the thylakoid membranes in the chloroplast.
What purpose do chloroplasts serve in plants cells?
it is the photosynthesis. It is a process making food.
What are the flattered membranes in chloroplasts called?
We call them thylakoids. We are using them grana too.
What color is in the chloroplast in a plant cell?
The color of chloroplast is green
Chloroplasts are filled with chlorophyll.So they are green.
Why do chloroplasts clump together in a elodea cell when salt water is added?
Because the cell shrinks so it pushes all the chloroplasts together.
Which set of chemical reactions is performed by the chloroplast of the cell?
There are two reactions. Those are dark reaction and light indipendant reaction.
Chloroplast transform light energy into chemical energy.So it is an energy transferer.
Where are chlorophyll pigments held in the chloroplast?
They are in thylakoid sacs.They are flattened sacs.
Where des carbohydrate occur in a chloroplast?
It is because of photosynthesis. glucose is forming as a carbohydrate.
What did chloroplast evolve from according to the endosymbiotic hypothesis?
They arose from a symbiotic union of two organisms.
Where do light dependent reactions occur in the chloroplast?
In the inner thylakoid membrane of the chloroplasts.
