EXPERIMENT a AIM To identify parenchyma and sclerenchyma tissues in plants from prepared slides and to draw their labelled diagrams.

Parenchyma tissue is composed of thin-walled cells and makes up the photosynthetic tissue in leaves the pulp of fruits and the endosperm of many seeds. Read formulas definitions laws from Simple Permanent Tissues here. Since plants are multicellular enclosing a huge number of cells each performing an activity.

Structurally they are long and narrow. NCERT Class 9 Science Lab Manual Plant and Animal Tissues. Sclerenchyma is also a simple permanent plant tissue containing dead cells with heavily lignified cell walls and functioning as a strengthening.

Diagram Of Parenchyma Collenchyma And Sclerenchyma on. They lack intercellular space. Can we think why they would lack vacuoles.

They have a little intercellular space. Complex permanent tissues are. Aim To identify parenchyma and sclerenchyma tissues in plants striated muscle fibres and nerve cells in animals from prepared permanent slides and to draw their labelled diagrams.

In collenchymas intercellular spaces are generally absent. Nervous tissue contains highly specialized unit cells called nerve cells or neurons. TISSUES Muticellular organisms are made of millions of cellsCells show division of labour and each cell performs a particular function efficiently.

Muscle cells are elongated and large sized so they are called. It provides flexibility and mechanical support to the plants. The major function of sclerenchyma is support.
