Introduction:
The stem is the main part of the plant that connects the photosynthetic leaves and roots. The primary function of the stem is the translocation of nutrients. The secondary growth of the stem is responsible for the support and protection of the plant.
To describe:
The changes that occur in the structure after the secondary growth.

- diagram the internal and external structures of a dicot stem after primary growth and after secondary growth?arrow_forwardName the cell layers in the stem of a monocot and a eudicot, moving from the epidermis to the innermost tissues.arrow_forward6) Match the tissue on the left with the description of the function it generally performs for the plant on the right: a) phloem flexible support, such as in petioles and herbaceous stems. b) xylem forms an outer barrier for leaves, young stems and roots. c) collenchyma conducts water and dissolved nutrients from the roots to other plant tissues. support of vascular tissue in older woody plants and formation of very hard plant structures such as nut shells. d) periderm e) parenchyma metabolism and storage. f) sclerenchyma conducts molecules produced by the plant throughout the plant body. g) epidermis provides physical protection for woody plants.
