Compléter pollination, nutrition and respirationVersion en ligne pollination, nutrition and respiration of plants par Irene VIQUE RUBIO 1 seeds Wind stamen Animal carpel Pollination Pollination is an important process in the reproduction of plants that have . It is the transfer of pollen from a to a . pollination is the transfer of pollen from the stamen to the stigma of another plant or of the same plant by an insect or a bird . pollination involves wind blowing the pollen from one plant to another . 2 minerals light carbon energy water Plant nutrition Plants make their own food . To do this they need , , and from the Sun and dioxide . 3 oxygen During the process of photosynthesis , plants release into the air . 4 roots The absorb water and minerals from the soil . Roots also fix the plant in the soil . 5 leaves stem The water and minerals travel up the to the passing through the stem vessels . 6 dioxide stomata chloroplasts chlorophyll Plants make food in their leaves . Leaves have tiny pores called through which carbon enters the plant . Plants also release oxygen through the stomata . The leaves are made up of very small cells . Inside these cells are tiny structures called . Each chloroplast contains a green chemical called which gives leaves their green colour and absorbs the light from the sun . Leaves use the light energy to convert water and carbon dioxide into sugar and oxygen . 7 oxygen carbon oxygen breathe Respiration Plants are living things and so they need to , just like people and animals . During the day they can also use the they produce during the photosynthesis process . At night , however , they must take in from the air and release dioxide . 8 Sugar Respiration occurs in every cell of the plant . is transported to all plant parts . Some sugar is stored and some is used for respiration producing energy and releasing water and carbon dioxide . 9 photosynthesis In plants take in carbon dioxide and release oxygen in the presence of light . 10 respiration In plants take in oxygen and release carbon dioxide into the atmosphere . 11 Photosynthesis and respiration help in maintaining a balance between oxygen and carbon dioxide in nature .
