Questions and Answers

What are the two major types of tissues in plants?

The two major types of tissues in plants are meristematic tissue and permanent tissue.

What distinguishes meristematic tissue from permanent tissue?

Meristematic tissue is capable of constant division, while permanent tissue consists of differentiated cells that do not divide.

Where is the apical meristem located and what is its function?

The apical meristem is located at the tips of the stem and root, and its function is to increase the length of the plant.

What role does lateral meristem play in plant growth?

Lateral meristem increases the girth or diameter of roots and stems. Signup and view all the answers

What is the intercalary meristem and where is it found?

The intercalary meristem is located on either side of nodes where leaves branch off the stem. Signup and view all the answers

What is the role of apical meristem in plant growth?

Apical meristem contributes to the increase in stem and root length, thus enhancing the height of the plant. Signup and view all the answers

Flashcards

Apical Meristem

A type of plant tissue responsible for increasing the length of the stem and root, found at the tip of the plant.

Lateral Meristem

A type of plant tissue found on the lateral sides of roots and stems, responsible for increasing the girth or diameter of the plant.

Intercalary Meristem

A type of plant tissue present on either side of the nodes (joints) in a stem, responsible for increasing the length of the internode region.

Permanent Tissues

Plant tissues that have lost their ability to divide, with a fixed shape and size. They can be made of living or non-living cells with thick or thin cell walls.

What are the characteristics of Permanent Tissues?

A specialized type of plant tissue that has lost its ability to divide. It has a fixed shape and size. The cell walls are usually thick.

Study Notes

Plant Tissues

Plant tissues are groups of cells that perform specific functions.
There are various types of plant tissues based on their structure and function.
These groups of cells are organized into permanent tissue and meristematic tissue.

Meristematic Tissues

Meristematic tissue is actively dividing cells.
These tissues are found in the growth regions of plants.
Meristematic tissues have thin walls and large nuclei.
There is no intercellular space.

Types of Meristematic Tissue

Apical meristem: Located at the tips of stems and roots, increasing plant height. If the tip is removed, height will not increase.
Lateral meristem: Located on the sides of stems and roots, increasing girth/diameter.
Intercalary meristem: Located at the base of leaves and internodes, increasing the length of the stem.

Permanent Tissues

Permanent tissues are formed from meristematic tissues.
They have lost their ability to divide.
These tissues are made of living or non-living cells with thick cell walls.
Categorized into simple and complex permanent tissues.

Observation of Plant Tissue Activity

Objective: Observation of plant tissue.
Materials: stem, blade, watch glass, safranin, glycerin, cover slip, microscope.
Procedure:
- Cut small, fine and thin sections of the stem of plants.
- Place the sections in a watch glass with water.
