Plant Tissues

Plant Tissues are stationary or fixed and most of them are dead. Dead cells provide mechanical strength and needs less maintenance. Some plant tissues divide through out the life while others not. So based on their dividing capacity, plant tissues are classified into: Meristematic Tissues and Permanent Tissues.


Plants are grouped on the basis of plant body components, presence of specialised tissues, ability to bear seeds, etc. Based on these factors, plants are classified as: Thallophyta Bryophyta Pteridophyta Gymnosperms Angiosperms Thallophyta: They do not have well-differentiated body design. They are predominantly aquatic. The plants of this group are commonly known as “Algae”. Eg:Continue reading “Plantae”
