Cambium, in plants can be defined as layers of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots. Secondary growth can be defined as occurring after the first season and results in increase in thickness
What else can I help you with?
If a stem has cork cambium is it woody or herbaceous?
If a stem has cork cambium, it is typically considered woody. The cork cambium (phellogen) is responsible for producing cork cells in woody plants, forming part of the protective outer bark. Herbaceous plants generally lack this cork cambium layer.
What is responsible for secondary growth in a stem?
Vascular cambium is responsible for secondary growth in a stem.
Which is the primary source of stem thickening in plants?
The primary source of stem thickening in plants is the vascular cambium, a layer of cells between the xylem and phloem tissues. The vascular cambium is responsible for producing new xylem and phloem cells, which leads to an increase in stem girth over time.
Produces cells to cover the stem and root surfaces?
Cork Cambium
Layer in the plant stem that separates xylem and phloem what is it called?
cambium
Do monocot stem have a vasular cambium?
No, no they do not. As well as not having a cortex, monocot stems don't have a pith either.
What is the layer between the xylem and phloem in decot stem?
A layer of cambium is found between xylem and phloem in dicot stem.
What are the six layers of a young woody stem?
The six layers of a young woody stem, from outermost to innermost, are the bark, cork cambium, cork, secondary phloem, vascular cambium, and secondary xylem. These layers provide structural support, transport nutrients and water, and protect the inner tissues of the stem.
What is the growth of tissue that produces phloem and xylem in the stems of woody plants?
The growth of tissue that produces phloem and xylem in the stems of woody plants is called vascular cambium. It is a lateral meristem that produces secondary xylem (wood) towards the inside of the stem and secondary phloem towards the outside, allowing for the thickening and expansion of the stem over time.
Are the tissues of the stem tip primary or secondary tissues?
The tissues of the stem tip are primary tissues, which are derived from the apical meristem. Secondary tissues, on the other hand, are produced by the lateral meristem (vascular cambium and cork cambium) and are responsible for increasing the girth of the stem over time.
What type of stem does not produce a cork cambium?
Herbaceous stems do not produce a cork cambium. Herbaceous stems are soft and pliable, composed mostly of primary tissues, while woody stems have secondary growth that includes the production of a cork cambium.
In older woody plants the epidermis of the stem is replaced by what tissue?
In older woody plants, the epidermis of the stem is replaced by periderm, which includes tissues such as cork cambium, cork cells, and phelloderm. Periderm helps protect the stem and replaces the functions of the epidermis as the plant matures and its stems thicken.
