Answer 1

Ответ:

Корка-это покровная ткань.

Кора с возрастом растения увеличивается и образуют пробку.

Луб-придает стеблю упругость, гибкость, сопротивление на излом

Камбий-за счет деления клеток происходит образование всех тканей.

Древесина-древесина с годичными кольцами помогает определить сколько лет растению

Сердцевина-она состоит из крупных, плотно прилегающих друг к другу клеток

#### Internal Structure of the Stem The stem is one of the main structural components of a plant. It provides support, transports water and nutrients, and serves as a site for photosynthesis and storage. The internal structure of the stem consists of several distinct zones, each with its own specialized tissues and functions. These zones include the cork cambium, cork, bark, cambium, and xylem and phloem. #### Cork Cambium The cork cambium is a layer of meristematic tissue located in the outermost part of the stem. It is responsible for producing cork cells, which make up the protective outer layer of the stem. The cork cambium also produces cells towards the inside, contributing to the formation of the phelloderm layer. #### Cork The cork is the outermost layer of the stem and is composed of dead cells that are rich in suberin, a waxy substance that makes the cork impermeable to water and gases. The cork protects the underlying tissues from mechanical damage, desiccation, and pathogens. #### Bark The bark refers to all the tissues outside the vascular cambium, including the cork, cork cambium, and the phloem. It serves as a protective layer for the stem and helps regulate the exchange of gases and water vapor between the plant and its environment. #### Cambium The cambium is a layer of meristematic tissue located between the xylem and phloem. It is responsible for the secondary growth of the stem, which results in an increase in girth. The vascular cambium produces new xylem cells towards the inside and new phloem cells towards the outside, contributing to the formation of annual growth rings. #### Xylem The xylem is a complex tissue that transports water and minerals from the roots to the rest of the plant. It is composed of several types of cells, including vessel elements and tracheids, which are responsible for the long-distance transport of water, and parenchyma and fibers, which provide support and storage. #### Phloem The phloem is another complex tissue that transports sugars, amino acids, and other organic compounds from the leaves to the rest of the plant. It is composed of sieve tube elements, which are responsible for the transport of sugars, and companion cells, which provide metabolic support to the sieve tube elements. #### Heartwood The heartwood is the innermost part of the stem and is composed of older, non-functional xylem cells. It provides structural support to the stem and may also store substances such as resins and tannins. #### Pith The pith is a central, spongy tissue found in the center of the stem. It is composed of parenchyma cells and may store water and nutrients. Each type of tissue in the stem has its own unique structure and function, contributing to the overall growth and development of the plant. The arrangement and organization of these tissues vary among different plant species and can be influenced by environmental factors. [[SOURCE 1]]
