1. The actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation is the basic unit of life. 2. A actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation organism consists of one cell which possesses a variety of structures enabling it to perform all the functions necessary for the maintenance of life. 3. A actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation organism consists of more than one cell. In advanced animals and plants these are arranged into tissues giving a division of labour. 4. actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation in cell structure exists between cells of one type of tissue and cells of different tissues since cells are actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation to perform particular functions. 5. Cells absorb molecules in solution by actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation , osmosis and active actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation . 6. The cell wall surrounding plant cells is made of actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation and is actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation permeable to solutions. It prevents the cell from actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation when water is absorbed. 7. The plasma actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation surrounding the living contents of all cells is selectively actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation . It consists of protein and actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation molecules thought to be arranged as in the fluid actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation model. 8. Tiny channels in the plasma membrane make it actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation and allow the actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation transport of small molecules by diffusion and osmosis along a concentration actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation . 9. Other chemical substances such as ions are actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation transported across the plasma membrane actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation a concentration gradient by actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation carriers. This process requires actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation .actively against bursting cell cellulose diffusion energy freely gradient membrane mosaic multicellular passive permeable phospholipids porous protein specialised transport unicellular Variation
