ARRANGE THE SCRAMBLED LETTERS FLASHED ON THE SCREEN PERTAINING TO CELL ORGANELLES. SMAOPCYTL NHMTORCOIDIA OIBSOREMS CLNEUSU  APSMLA EMBARNEM  The cell is the basic unit of life. Our body is made up of billions of them. A cell is like a tiny system. Inside the cell are organelles with different functions. Among these organelles are: nucleus, mitochondria, Golgi bodies, cell membrane.  Cells, just like any other life forms, must obtain needed materials from the outside environment for survival. materials such as waste products that are no longer needed by the cell must be eliminated from its interior to the outside environment. The cell structure responsible for directing the traffic of materials in and out of the cell is the cell membrane. But how does the cell membrane perform such function? Two major ways of directing materials in and out of the cells. Passive Active  ACTIVITY 1 : DIFFUSION PROCEDURES: 1. FILL ONE GLASS CUP WITH HOT WATER. FILL THE SECOND GLASS WITH COLD WATER. 2. PUT 1-2 DROPS OF RED FOOD COLORING IN THE HOT CUP, AND 1-2 DROPS OF BLUE FOOD COLORING IN THE COLD ONE. 3. WATCH AND WAIT FOR COLOR TO DISPERSE ENTIRELY. OBSERVE. 4. WHAT WOULD YOU OBSERVE? WHICH ONE DISPERSED QUICKLY? WHAT WOULD BE THE REASON? EXPLAIN. Aquaporins are channel proteins that allow water to cross the membrane very quickly, and they play important roles in plant cells, red blood cells, and certain parts of the kidney (where they The key regulator of the water circulation is minimize the amount of the aquaporin protein. water lost as urine).  TEMPERATURE Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases. HUMAN CELL PLANT CELL  TELL ME SOMETHING! Give example of osmosis that we experience in our daily activities at home or at school.  APPLICATION OF OSMOSIS When we sit in the bathtub or submerge our fingers in water for a while they got wrinkly. The skin of our fingers absorb water and get expanded or bloated; leading to the pruned or wrinkled fingers.  Our sweat glands use osmosis. our body doesn't pump water to our skin in the form of sweat. Instead it deposits a little bit of salt inside one of our sweat glands. The water that makes up 70% of our body is attracted to this salt.  The absorption of water from the soil is due to osmosis. The plant roots have a higher concentration than the soil. Therefore, the water flows into the roots. The guard cells of the plants are also affected by osmosis. GENERALIZATION MAKE A CONCEPT MAP ON THE CELL MEMBRANE TRANSPORT MECHANISM
