Biology 10(B). Learning objectives. Identify . major systems in plants. Describe the interactions that occur among systems to carry out vital plant functions. Interactions Among Plant Systems. Organ systems:. Lab 11. Plant Tissues. Tissues. A group of closely associated cells that perform related functions and are similar in structure.. Plant Tissues can classified into. :. Meristematic tissues . .. Permanent tissues.. Baseline (Flightpath D): . To be able to recognize examples of plant organs, state their functions and use a light microscope to view a cross-section of a leaf. State the functions of different plant tissues. Biology Department. Plant Tissues. Tissues can be classified into . :. Meristematic. tissues. . Permanent . tissues. I . . Meristematic. . tissues. They are usually called meristems. . They . are young tissues of the embryo or the mature plant which . “Cells, Tissues, Organs & Systems”. Levels of Organization. Tissues. Groups of similar cells. Found in all multicellular organisms.

S. - a cell continues to grow but copies its DNA. G2. - still growing but begins to store energy and get ready to divide. Dr.Duran Kala. 4-. 2. Tissues and Histology. What is a Tissue?. A collection of similar cells and noncellular substances (extracellular matrix) secreted by the cells. Tissue Level of Organization. Epithelial . 27.1: carbon sequestration. By the process of photosynthesis, plants naturally remove carbon from the. a. tmosphere and incorporate it into their tissues. Carbon that is locked in . m. olecules of wood and other durable plant tissues can stay out of the. Topic. : . Meristem. & Plant Secondary Growth. B.Ed. (. Hons. ) Secondary. Semester III.
