Introduction
Simple permanent tissue =similar type of cells with common origin and function.
Pre-Requisites:
Permanent tissues lose the ability to divide and grow & have specific function to perform.
Activity:
Observe the different types of plant to view the tissues with the help of biology teacher.
Real Life Question:
How do meristematic tissues differentiate to form different types of permanent tissues?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Parenchyma Chlorenchyma Aerenchyma Collenchyma Sclerenchyma Epidermis Stomata Suberin | Relatively unspecialized cells with thin cell walls. (Live cells) Provides support. Parenchyma containing chlorophyll and performs photosynthesis. Parenchyma type that provides buoyancy to aquatic plants Thin-walled cells with cellulose and pectin substances. Give tensile strength to the plant. (Living tissue) Thick-walled and dead cells Single layer of cells on the entire surface of the plant. Small pores on the epidermis of the leaf, necessary for gas exchange. Chemical present in cork cells that make them unaffected by gases and water. |
