Match the terms given in column I with their functions given in column II and fill the blanks given below the table: Column I Column II A. Chloroplast i) carries hereditary characters B. Cell membrane ii) controls the activities of cells C. Nucleus iii) site of photosynthesis D. Chromosome iv) controls the movement of materials into and out of cells.

A - iii Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP. B - iv Plasma membrane is a thin membrane that surrounds every living cell, separating it from the external environment around it. It controls the movement of materials into and out of cells. C - ii Nucleus controls the activities of cells. It is present in the centre of the cell. It is separated from the rest of the cell or the cytoplasm by a nuclear membrane. D - i Chromosome carries hereditary characters as it contains the genes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Column I Column II A. Chloroplast iii) site of photosynthesis B. Cell membrane iv) controls the movement of materials into and out of cells. C. Nucleus ii) controls the activities of cells. It is present in the centre of the cell. D. Chromosome i) carries hereditary characters as it contains the genes.
