PLANT TISSUES

Hello and welcome to my blog, this blog is all about plant tissues

A cell is the basic structural and functional unit of life in all living beings. In multicellular organisms such as plants and animals, the cells with similar structure and functions are grouped together. These groups of similar cells are called tissues. In this chapter, you will learn about different types of plant tissues and their functions.

Types of plant tissues

On the basis of the stages of development of their cells and the functions they perform, plant tissues are divided into two types.

• Meristematic tissue • Permanent tissue

Meristematic tissue

Have you ever wondered how a tiny seedling grows into a huge tree? When the embryo in a seed begins to grow, we say the seed is germinating. The embryo has a group of cells at its root and shoot tips. These cells are small, thin-walled and full of cytoplasm. They have a large nucleus. They divide rapidly and continuously as a result of which the plant gains height. This group of actively dividing cells forms the meristematic tissue. This tissue is found in all the growing parts of a plant where growth in length and thickness of a plant occurs. For example, root and shoot tips contain meristematic tissues

The main function of meristematic tissue is to produce new cells at the root and shoot tips and build up plant body in length and thickness.

Characteristics of meristematic tissue

The main characteristics of meristematic tissue are as follows. The cells are small in size, cell wall is thin, nuclei are

prominent and vacuoles are mostly absent. The cells actively divide to form new cells.

Types of meristematic tissue

Depending on their location in the plant body, meristematic tissue is of two types.

Apical meristematic tissue It is present at the root and shoot tips. It increases the length of the plant. gains height, the

Lateral meristematic tissue As a tree

diameter of its stem also increases. The tree gains thickness because of the meristematic tissue present on the lateral sides of the root and stem. This tissue is called the lateral meristematic tissue or cambium. It is responsible for the increase in the thickness of the roots and stem.

That is it! I will continue Permanent tissues in another blog
THANK YOU!

  My passion Everyone has their own passion. My passions are art and cooking. Since childhood, I have learnt drawing and painting which had both modern and traditional arts. I have learnt one-point perspective, caricature, cartoon, paper collage, traditional art forms etc. I made these art works using colour pencils, crayons, soft pastels, water colours, oil pastels etc. Nowadays I am trying to draw traditional art forms like Warli, Madhubani, Kalighat, Mural, Pattachithra, Gond, Miniature etc. I was so excited when I received India Book of Records. I make art works on A4 size or A3 papers, cardboard, canvas etc. I will be making new and creative art every week. I am planning to do certificate courses and join classes to become more perfect. Art makes very happy and gives me satisfaction. I feel so proud. My other passion is cooking. I love spicy and lip smacking dishes. I learn cooking from my grandmother, mother and youtube channels. I also watch Master Chef Australia where the p...
