Question

I have been given an art integration project of Power point presentation on Morphology of flowering plants of Ladakh and West Bengal based on the Morphology of flowering plants of class 11th biology. Can any one of you give me some Idea please. Thank you.

Morphology of flowering Plant Speaker Mr. Pranay P Pandey2. Morphology of Plants  Morphe= Form + Logos= Study  Study of form and feature  Root  Stem  Leaf  Inflorescence  Flower  Fruit  Seed3. Classification of Plants  Annuals: Complete their life cycle in one year or one growing season or few weeks to a few months. eg. Mustard, corn, wheat, rice, lettuce, peas, watermelon, beans, zinnia and marigold.  Biennials: Complete their life cycle in two years growing (vegetative and storing food in the first year, flowering and fruiting in second year). eg. Radish, Turnip, Carrot, Onion and Cabbage.  Perennials: Survives for several years. Generally the top portion of the plant dies back each winter and regrows the following spring from the same root system. eg. Mango, Guava and Banana.

Answer:

Morphology of flowering plants - I (root, stem & leaf)

1. Morphology of flowering plants dr.aarif 1.Root 2.Stem 3.Leaf 4.Flower 5.Fruit 6.Seed

2. dr.aarif Morphology of Root Characteristics : 1. Root is defined as the descending part of the plant axis. 2. It is positively geotropic. 3. It is positively hydrotropic 4. It is negatively phototropic. 5. It develops from the radicle of the embryo during seed germination. 6. Roots are generally non green and cylindrical. 7. They produce only similar organs i.e. secondary and tertiary roots 8. They do not show nodes and internodes

3. Morphology of Root 1. Region of root cap: - The tender apex of the root is protected with a multicellular cap like structure called root cap. - The cells of the root cap secrete mucilage for lubricating the passage of root through the soil. - In many hydrophytes like Pistia and Eichhornia, root cap is replaced by root pocket. 2. Region of cell division or meristematic region: - It is a small region about 1mm in length. - This is the growing part of the root and is protected by the root cap. - It is made up of thin walled, compactly arranged meristematic cells which have the power of division. - This region helps in longitudinal growth by the addition of new cells 3. Region of elongation: - It lies just above the meristematic region. - The cells of this region are newly formed and they elongate rapidly. This increases the length of the root. - The cells of this region help in the absorption of mineral salts dr.aarif
