Sclerenchyma:

What are the Characteristics:

• dead cells with no content • thickened lignified walls

Simple tissue:

it is made up of cells which are similar in structure and perform a common function. Complex tissue: It is made up of more than a single type of cells which work together to perform a common function. The complex tissues include xylem and phloem. They together constitute the vascular system of the plant.

Sclerenchyma:

What are the Characteristics:

• dead cells with no content • thickened lignified walls

Ecosystem is a community of organisms and their abiotic components interacting as a unit.

An ecosystem consists of the biotic and the abiotic component. The biotic components are living components such as plants and animals and the abiotic components are non-living components such as water, soil and climate.
