Introduction
Simple permanent tissue =similar type of cells with common origin and function.
Pre-Requisites:
Permanent tissues losses 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 | Relatively unspecialized cells with thin cell walls. (Live cells) Provides support. |
| Chlorenchyma | Parenchyma containing chlorophyll and performs photosynthesis. |
| Aerenchyma | Parenchyma type that provides buoyancy to aquatic plants |
| Collenchyma | Thin-walled cells with cellulose and pectin substances. Give tensile strength to the plant. (Living tissue) |
| Sclerenchyma | Thick-walled and dead cells |
| Epidermis | Single layer of cells on the entire surface of the plant. |
| Stomata | Small pores on the epidermis of the leaf, necessary for gas exchange. |
| Suberin | Chemical present in cork cells that make them unaffected by gases and water. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Microscope | View and identify the tissues (mounted cells) |
