What are three adaptations of a chloroplast?

Chloroplast

• They have a double membrane structure (due to vesicular coating as part of the endocytotic process)
• They have their own DNA (circular and naked) and ribosomes (70S)
• Their metabolic processes are susceptible to certain antibiotics.

What structural features do mitochondria and chloroplasts share?

The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane. The differences in structure for these organelles are found in their machinery for energy conversion.

What are the two components of a photosystem?

Chlorophyll a Is Present in Both Components of a Photosystem A photosystem has two closely linked components, an antenna containing light-absorbing pigments and a reaction center comprising a complex of proteins and two chlorophyll a molecules.

What are the similarities and differences between chloroplast and mitochondria?

Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both. Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients. Chloroplast is the site for photosynthesis in a plant cell.

What are the similarities and differences between chloroplasts and mitochondria?

What are the two main function of chloroplast?

The main role of chloroplasts is to conduct photosynthesis. They also carry out functions like fatty acid and amino acid synthesis.

What’s the difference between mitochondria and chloroplast?

Difference Between Mitochondria And Chloroplast. Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both. Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients. Chloroplast is the site for photosynthesis in a plant cell.

What makes up the inner membrane of a chloroplast?

Like mitochondria, chloroplasts have outer and inner membranes, but within the space enclosed by a chloroplast’s inner membrane is a set of interconnected and stacked, fluid-filled membrane sacs called thylakoids ( Figure 2 ). Each stack of thylakoids is called a granum (plural = grana).

How are chloroplasts different from plant and animal cells?

The chloroplasts contain a green pigment called chlorophyll, which captures the energy of sunlight for photosynthesis. Like plant cells, photosynthetic protists also have chloroplasts. Some bacteria also perform photosynthesis, but they do not have chloroplasts.

Where are chloroplasts located in a protist cell?

Like plant cells, photosynthetic protists also have chloroplasts. Some bacteria also perform photosynthesis, but they do not have chloroplasts. Their photosynthetic pigments are located in the thylakoid membrane within the cell itself. We have mentioned that both mitochondria and chloroplasts contain DNA and ribosomes. Have you wondered why?
