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 . ... Photosystems – pigments organised into photosystems in thylakoid membrane to maximise light absorption.
How does the structure of a chloroplast make its function more efficient?
Part of the photosynthesis reactions occur in an internal membrane within the organelle. The chloroplast contains many of these internal membranes, making photosynthesis very efficient. These internal membranes stack on top of each other, just like a stack of pancakes.
Why is the structure of a chloroplast important?
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.
How does the structure of chloroplast relate to its function quizlet?
Structure: Chloroplasts have an outer membrane, intermembrane space, and an inner membrane. Inside the chloroplasts there are stacks of thylakoids called granum. ... The chloroplasts use photosynthetic chlorophyll pigment and take in sunlight, water, and CO2 to produce glucose and oxygen.
What are the structures and function of the structures found in a chloroplast?
The chloroplast has an inner and outer membrane with an empty intermediate space in between. Inside the chloroplast are stacks of thylakoids, called grana, as well as stroma, the dense fluid inside of the chloroplast. These thylakoids contain the chlorophyll that is necessary for the plant to go through photosynthesis .
What are the 5 parts of chloroplast?
The parts of a chloroplast such as the inner membrane, outer membrane, intermembrane space, thylakoid membrane, stroma and lamella can be clearly marked out.
What is the main structure of chloroplast?
Chloroplasts are enclosed by an envelope of two membranes which encompass a third complex membrane system, the thylakoids , including grana and lamellae. In addition, starch grains, plastoglobules, stromules, eyespots, pyrenoids, etc. are also important structures of chloroplasts.
What is the main function of chloroplasts quizlet?
The two main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy .
Which of the following is a function of chloroplasts quizlet?
Chloroplasts capture energy from sunlight and convert it into food that contains chemical energy in a process called photosynthesis.
What is function of thylakoid?
Thylakoids are the internal membranes of chloroplasts and cyanobacteria, and provide the platform for the light reactions of photosynthesis .
What are 3 functions of chloroplast?
- Absorption of light energy and conversion of it into biological energy.
- Production of NAPDH2 and evolution of oxygen through the process of photosys of water.
- Production of ATP by photophosphorylation.
What are the two main functions of chloroplasts?
The main role of chloroplasts is to conduct photosynthesis . They also carry out functions like fatty acid and amino acid synthesis.
What is the basic unit of structure and function of living things?
The cell is the basic unit of all forms of life. However, there are several levels of cell organization within many multicellular organisms. Cells are arranged in hierarchical levels of organization. The lowest form of organization is the cell followed by tissues, organs, and organ systems.
What are the three major parts of a chloroplast?
In particular, their three membranes divide chloroplasts into three distinct internal compartments: (1) the intermembrane space
Why are chloroplasts green?
Chlorophyll is located in a plant's chloroplasts, which are tiny structures in a plant's cells. ... Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light . That particular light wavelength is reflected from the plant, so it appears green.
What does chloroplast look like?
Chloroplasts are a type of plastid—a round, oval, or disk-shaped body that is involved in the synthesis and storage of foodstuffs. Chloroplasts are distinguished from other types of plastids by their green colour, which results from the presence of two pigments, chlorophyll a and chlorophyll b.
