Question

hello everyone
please provide me some pointers of chapter anatomy of flowering plants..
it's urgent..
if u can the please notes at the level of neet.

thanks.
no SPAMS PLEASE. ​

Answer 2

Types of Plant Tissue

There are two types of plant tissue: Meristematic Tissue and Permanent Tissue.

Meristematic Tissue

Meristematic Tissue is composed of group of cells that have the capability of division. These cells are responsible for overall growth of the cells.

There are three types of Meristem:

Apical Meristem is present on the apices of the root and shoot. It contains actively dividing meristematic cells.

Lateral Meristem help plants to grow laterally.

Intercalary Meristem is found at the base of nodes and leaf blades. They help the plants to grow and increase in size.

Permanent Tissues

There are two types of Permanent Tissues: Simple and Complex.

Simple Tissues- There are three types of Simple Tissues. They are as follows:Parenchyma is found in Epidermis, Pericycle, Cortex and Pith. They are simple and unspecialized cells. They are involved in Photosynthesis, storage of food etc. 

Collenchyma are living cells with chloroplasts for photosynthesis.

Sclerenchyma Cells are long, lignified cells with tapering ends. These are dead cells and are involved in mechanical function.

What is Anatomy of flowering Plants?

The study of Internal Structure of an organism is known as Anatomy. Plant Anatomy includes studying of organization and structure of tissues.

Tissue is a group of similar cells that perform specific functions. 

 

Types of Plant Tissue

There are two types of plant tissue: Meristematic Tissue and Permanent Tissue.
 

Meristematic Tissue

Meristematic Tissue is composed of group of cells that have the capability of division. These cells are responsible for overall growth of the cells.

There are three types of Meristem:

Apical Meristem is present on the apices of the root and shoot. It contains actively dividing meristematic cells.

Lateral Meristem help plants to grow laterally.

Intercalary Meristem is found at the base of nodes and leaf blades. They help the plants to grow and increase in size.
 

Permanent Tissues

There are two types of Permanent Tissues: Simple and Complex.

 Simple Tissues- There are three types of Simple Tissues. They are as follows:Parenchyma is found in Epidermis, Pericycle, Cortex and Pith. They are simple and unspecialized cells. They are involved in Photosynthesis, storage of food etc.

Collenchyma are living cells with chloroplasts for photosynthesis.



Fig.2. Collenchyma Cells

Sclerenchyma Cells are long, lignified cells with tapering ends. These are dead cells and are involved in mechanical function.

Complex Tissues- It includes Xylem and Phloem.Xylem is composed of four elements:

Tracheid are dead cells with hard, lignified walls. They have tapering, blunt ends. It helps in conduction of water in plants.

Vessels are tube-like structures which are dead at maturity. They are involved in transport of water as well as in providing mechanical support to the plant.   

 Xylem fibers are lignified with pointed ends. They help in conduction of water and nutrients from root to the leaf.Xylem parenchyma are living cells that store starch and fats.
