TCA: Biology: Plant CellVersión en línea label the correct description por Elvira Trevino 1 Ribosomes are sites for protein building. 2 Mitochondria release energy from simple sugars to power the cell (respiration). 3 Chloroplasts are green organelles that capture light energy to make food (photosynthesis). 4 A storage unit filled with fluid, called a vacuole, forms the central part of each cell. 5 Cytoplasm is a jellylike substance that fills much of the space inside the cell. This is where chemical reactions occur. 6 The nucleus is the cell's control center. It stores the cell's genes encoded in molecules of DNA. 7 A thin cell membrane inside the cell wall controls which substances enter and leave the cell. 8 A rigid cell wall made of a substance called cellulose surrounds the cell membrane and supports the cell.
