Answer 2

SHORT NOTE ON PARENCHYMA

Parenchyma Is The Common Type Of Plant Tissue. It Is Thin Walled. They Are Loosely Packed. They Are Mostly Oval Or Round In Shape. These Are Found In Leaves, Fruits And Flowers. These Are Also Located In The Soft Areas Of Stem, Root And Leaves. Their Primary Function Is Storage Of Food And Water. They Are Two Types, Simple Parenchyma Forms The Ground Tissue. Chlorenchyma Is The Photosynthetic Tissue Of A Plant.

SHORT NOTE ON FLUID MOSAIC OF PLASMA MEMBRANE

The Fluid Mosaic Describes The Structure Of Plasma Membrane As A Mosaic Of Components - Including Phospholipids, Cholesterol, Protein, And Carbohydrates That Gives The Membrane A Fluid Character. For Example, Myelin Contains 18% Protein And 76% Lipid And The Mitochondrial Inner Membrane Contains 76% Protein And 24% Lipid.

SHORT NOTE ON COLLENCHYMA

Collenchyma, In Plants, Support Tissue Of Living Elongated Cells With Irregular Cell Walls. Collenchyma Cells Have Thick Deposits Of Cellulose In Their Cell Walls And Appear Polygonal In Cross Section. The Strength Of The Tissue Results From These Thickened Cell Walls And The Longitudinal Interlocking Of The Cells.
