What is the relationship between photosynthesis and chloroplasts?

Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

How does chloroplast structure affect photosynthesis?

The structure of the chloroplast is adapted to the function it performs: Thylakoids – flattened discs have a small internal volume to maximise hydrogen gradient upon proton accumulation. Lamellae – connects and separates thylakoid stacks (grana), maximising photosynthetic efficiency.

Why do plants need both chloroplasts and mitochondria?

Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.

How do chloroplasts and mitochondria work together?

-Chloroplasts convert the sunlight (absorbed by the chlorophyll) into food, and then mitochondria make/produce energy out of the food in the form of ATP. Note: Chlorophyll is present within the Chloroplast, and this chlorophyll absorbs/captures sunlight.

Why is the chloroplast structure related to its function?

Just like the structure of the mitochondria was important to its ability to perform aerobic cellular respiration, the structure of the chloroplast allows the process of photosynthesis to take place. Both the light-dependent reactions and the Calvin cycle take place inside of the chloroplast.

Do all plant cells have chloroplasts for doing photosynthesis?

This process occurs in almost all plant species and is carried out in specialized organelles known as chloroplasts. All of the green structures in plants, including stems and unripened fruit, contain chloroplasts, but the majority of photosynthesis activity in most plants occurs in the leaves.

How are chloroplast and chlorophyll related to each other?

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4).

What is the role of chloroplast in plant?

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.

What is the relationship between mitochondria and chloroplasts?

In plant cells, chloroplasts convert light energy into chemical energy, and mitochondria consume the chemical energy to produce ATP. The optimal carbon fixation and plant growth require these two energy-transforming organelles to perform strictly coordinated actions.

What are the similarities between mitochondria and chloroplasts?

Similarities between mitochondria and chloroplast: Mitochondria and chloroplast both are bounded by double membrane envelope. Both mitochondria and chloroplast are semi autonomous organelles. Mitochondria and chloroplast both have their own genome (DNA)i.e genetic material.

What is the similarities of mitochondria and chloroplast?

The main similarity between mitochondria and chloroplast is energy production i.e. they convert energy out of the cell into a specific form and then this energy is used by the cell. 2. The DNA and RNA of mitochondria and chloroplast are almost similar. Both the DNA are circular.

Does photosynthesis always require chloroplasts?

The light reaction in photosynthesis always takes place in the grana of the chloroplasts. On the other hand, the dark reactions always take place in the stroma of the chloroplasts. Since the light reactions take place during the daytime, they require the processes such as photosystem 1 and photosystem 2.

What contains chlorophyll for photosynthesis?

The organelle in the plant cell that is the site of photosynthesis and contains chlorophyll pigment is called CHLOROPLAST. Chloroplasts are found in the plants and contain DNA like mitochondria. These are also the site of ATP production.

Does photosynthesis use chlorophyll?

The main use of chlorophyll for photosynthesis is to capture the electromagnetic light energy from the sun. Sunlight is broken up into a spectrum of colors, the visible portion of which humans see in rainbows and in light shone through prisms.

Do photosynthetic bacteria have chloroplasts?

Purple photosynthetic bacteria do not contain chloroplasts. They have an antenna system that includes two light harvesting protein complexes, both of which are integral membrane proteins. The bacteriochlorophyll a molecules contain Mg 2+ and absorb light at 800 nm.
