What is the difference between the epidermis and the periderm?
The periderm is the secondary protective (dermal) tissue that replaces the epidermis during growth in thickness of stems and roots of gymnosperms and dicotyledons (i.e., secondary growth). Unlike the epidermis, the periderm is a multilayered tissue system, the bulk of which usually constitutes the cork, or phellem.
What are the different types of secondary growth in dicots?
1. Normal type of secondary growth in the cortical and vascular regions adding to the secondary xylem ,secondary phloem and periderm at their proper places 2. Various types of anomalous secondary growth putting paches of xylem & phloem abnormally.
What is extrastelar secondary growth?
Extra stelar secondary growth occurs due to th activity of cork cambium.... It produces cork cells and parenchyma cells.... In extra stelar secondary growth there is no annual ring formation.... It later on leads to the formation of periderm and lentices.... sanjana arun
What is responsible for secondary growth in a stem?
Vascular cambium is responsible for secondary growth in a stem.
Which group of plant has secondary growth and which never do?
Gymnosperms and dicots have secondary growth, which is the ability to grow in girth and produce wood. In contrast, monocots do not exhibit secondary growth and rely on primary growth for their development.

What terms best describe tree bark?
Periderm is another term for tree bark. It comprises tissue surrounding cork cambium.
What is Periderm?
Periderm, also known as bark is the outermost layer of stems and roots of woody plants.
What is responsible for secondary growth in a stem?
Vascular cambium is responsible for secondary growth in a stem.

Which are the part of a periderm?
The periderm is composed of three layers: cork (phellem) on the outside, cork cambium (phellogen) in the middle, and phelloderm on the inside. The periderm serves as a protective layer in woody plants to replace the epidermis as the plant matures.
Do Woody plants lack secondary growth?
No, woody plants do not lack secondary growth. Secondary growth is the process by which plants increase their girth through the production of secondary tissues such as wood and bark, which woody plants exhibit. This growth allows woody plants to increase in size and longevity.
What is difference between primary growth and secondary growth?
Primary growth is when the stem or root of a plant gets lengthens, and secondary growth is when the stem/root gets thicker.
Do all angiosperms undergo secondary growth?
No, not all angiosperms undergo secondary growth. Secondary growth is primarily seen in woody angiosperms like trees and shrubs, where it contributes to the thickening of stems and roots. Herbaceous angiosperms, on the other hand, typically do not exhibit secondary growth.
How does a lenticel differ from the remainder of the periderm?
A lenticel is a specialized pore found in the periderm that allows for gas exchange in woody stems and roots. The remainder of the periderm includes the cork cambium and cork cells, which form the protective outer layer of the plant. Lenticels are distinct in their role of facilitating gas exchange, while the rest of the periderm acts as a barrier to protect underlying tissues.
