In the plant cells, chloroplasts are called as organelles. It is very important for the life of a plant. Without chloroplasts, the plants won’t be able to cook their own food. They cannot perform the photosynthesis process.

Red blood cell, cellular component of blood that carries oxygen from the lungs to the tissues and gives vertebrates’ blood its characteristic color. The mature human red blood cell is small, round, and biconcave. Red blood cells also carry carbon dioxide, a waste product, to the lungs, where it is excreted.

Cell - Mitochondria, Energy, Organelle: Through a series of metabolic reactions carried out in the matrix, the mitochondrion converts products of the cell’s initial metabolism of fats, amino acids, and sugars into the compound acetyl coenzyme A. The acetate portion of this compound is then oxidized in a chain reaction called the tricarboxylic acid cycle. At the …Cell - Photosynthesis, Respiration, Metabolism: NADPH remains within the stroma of the chloroplast for use in the fixation of carbon dioxide (CO2) during the Calvin cycle. In a complex cycle of chemical reactions, CO2 is bound to a five-carbon ribulose biphosphate compound.

It is this pigment that imparts a green color to plant parts and serves to capture light energy. Chloroplasts can be found in the cells of the mesophyll in plant leaves.Cytoplasm is a clear substance that is gel-like in the cell membrane but is on the outside of the nucleus.

Moreover, chloroplasts are only one of several types of related organelles ( plastids) that play a variety of roles in plant cells. Go to: The Structure and Function of Chloroplasts Plant chloroplasts are large organelles (5 to 10 μm long) that, like mitochondria, are bounded by a double membrane called the chloroplast envelope ( Figure 10.13 ).Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. 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 chloroplast is a double membrane organelle found in plants and certain algae cells. The main function of the chloroplast is to convert energy from the Sun into chemical energy (glucose) for growth, a process called photosynthesis.
