How does the structure of chloroplast help its function?
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.
What is the structure of a 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 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 functions do chloroplasts perform?
Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.
Why are chloroplasts important to the structure of a plant?
The chlorophyll pigment, present in, the cells, captures the energy from sunlight and, stores it in, the plant’s energy store, molecules. Using carbon dioxide, the energy is converted into organic compounds within, the plant’s structure. They release, the oxygen, from water in the plant, too.
What kind of organelle is the chloroplast?
Chloroplasts are a type of cell organelle. The chloroplast is the kitchen of the plant cell. The bi-membraned cytoplasmic organelles present in plant cells that help photosynthesis and the organelles that turn the leaves green are called a chloroplast.
Where does the energy from chloroplasts come from?
The reactants of one are the products of the other. Both plant and cells from all other eukaryotic kingdoms derive their energy from the glucose made in chloroplasts; and, this is done through cellular level respiration in organelle structures called mitochondria.
Where does the word chloroplast come from?
Chloroplasts are one of the cell organelles of plant cells. Chloroplast structure and function are discussed below (1). The word chloroplast comes from the Greek words khloros and plastes. Khloros means “green”, and the word plastes means “formed”.
