UNIT 2 The nutrition function Natural Science 2. Secondary Education AUTOTROPHIC AND HETEROTROPHIC PLANT CELLS

UNIT 2 Autotrophic and heterotrophic plant cells Plants, as you know, are autotrophic organisms, which means they produce their own food from inorganic matter. However, as multicellular organisms, they have both autotrophic and heterotrophic cells. Natural Science 2. Secondary Education

UNIT 2 Autotrophic cells are found in the green parts of plants, like the leaves and stems, which contain chloroplasts, where photosynthesis is carried out. Autotrophic plant cells The cells of this leaf are autotrophic because they contain chloroplasts, which is where photosynthesis is carried out. Autotrophic and heterotrophic plant cells Natural Science 2. Secondary Education

UNIT 2 Heterotrophic cells cannot make organic matter by themselves because they do not have chloroplasts. These cells obtain their nutrients from the phloem sap that is made in the plant’s autotrophic cells. Heterotrophic cells are found in the non-green parts of plants, like roots and woody stems. Heterotrophic plant cells Root hair cells do not carry out photo- synthesis, so they are heterotrophic. Autotrophic and heterotrophic plant cells Natural Science 2. Secondary Education
