Points to Remember
Students can check the important points to be remembered from NCERT Class 9 Science chapter 6 to score good marks in the exams.
Plant tissues are of two main types. They are meristematic and permanent tissues.
Meristematic tissues are dividing tissues present in the growing regions of the plant.
Apical meristem plays a vital role in the primary growth of plants. It increases the length of the plant, while lateral meristem increases the diameter or thickness of the plant. It plays a vital role during secondary growth in dicot plants.
Permanent tissues are derived from meristem tissues when they lose the ability to divide. They are classified as simple and complex tissues.
Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. Xylem and phloem are types of complex tissues.
The outermost and protective layer of the plant cell is called the epidermis.
The small pores present in the epidermis of the leaf are called stomata.
The guard cells, subsidiary cells and stomatal pores constitute the stomatal apparatus.
Stomata regulate the exchange of gases and transpiration.
The xylem is a water-conducting tissue. It is composed of the trachea (vessel), tracheids, xylem parenchyma and xylem sclerenchyma.
Phloem is a complex food conducting tissue. It is made of sieve tubes, companion cells, phloem parenchyma, and phloem sclerenchyma.
