Biology
Samay is working on a school project for his biology class. His teacher asks him to study plant growth at tissue level and identify the specific tissues involved in this process. He sows a few soaked bean seeds in his kitchen garden and observes the sprouts under a microscope. He notices actively dividing cells in the growing regions of the plant.
(a) Name the type of tissue observed by Samay that has the ability to divide repeatedly and produce a large number of cells in a particular region.
(b) Write two specific locations in the plant body where the above mentioned tissue can be found.
(c) State any two main characteristic features of the cells of this tissue.
(d) What are the 2 main categories of this tissue ?
