Objectives

---

At the end of this lesson the students will be able to: - Understand vascular tissue system- their types and functions. - Know the structure of dicot root, stem, leaf and monocot root, stem, leaf. - Differentiate the internal structure of dicot root, stem, leaf with that of monocot root, stem, leaf. - Name the different pigments found in chloroplast. - Elaborate on the structure and functions of plastids. - Enumerate the steps involved in photosynthesis. - Understand the structure of mitochondria - List the basic events of aerobic and anerobic respiration

Points to remember

---

- Tissue is a group of similar or dissimilar cells, having a common orgin and performing similar functions. - Plants are capable of synthesizing glucose from CO2 and H2O in the presence of light, by the process of photosynthesis. - Light reaction takes place in grana of chloroplast. - Dark reaction takes place in stroma of chloroplast. - Respiration involves both external and cellular respiration. - Aerobic respiration takes place in the presence of oxygen. - Aerobic respiration occurs in three major steps like Glycolysis, Krebs cycle and Electron transport chain.
