The potato in the distilled water beaker should have gained weight due to more water moving in. This potato had a lower water potential to begin with, in comparison to the water beaker. It was less dense and as a result, the water moved in. The rate of movement into and out of cells is influenced by three main characteristics/ processes: 1. Part Function Found in; Cell membrane: Controls the movement of substances into and out of the cell: Plant and animal cells: Cytoplasm: Jelly-like substance, where chemical reactions happen. This results in random movement of molecules until equilibrium is reached. The diffusion of gases and solutes is important as without it, molecules which are needed for life, for example glucose and oxygen for respiration, would not be able to get to the places they are needed. Water is needed as a solvent. Factors influencing faster diffusion:. Movement of ions in and out of cells through the membrane from a region of lower concentration to a region of higher concentration. This requires energy released during respiration. Term. Osmosis. Definition. Diffusion of water molecules from a region of higher concentration to a region of lower concentration. Term. The IGCSE and A Level biology notes cover numerous topics including: • Characteristics and classification of living organisms • Organization of the organism • Cell Structure • Movement in and out of cellsCell membrane and transport • Biological molecules • Enzymes • Plant nutrition • Human nutrition • Transport in plants. 8. Label the following diagrams of Red Blood Cells and Plant Cells as being examples of cells contained in Isotonic, Hypertonic and Hypotonic solutions. 9. Strawberry jelly is a very strong solution of sugar. By contrast the cytoplasm in bacteria is a much weaker solution. The cell wall of bacteria is made up of a semi-permeable membrane. Ciliated cellsmove mucus upward. Root hair cells – absorb water and mineral salts. Xylem vessels – transport water and mineral salts; help in support. Palisade mesophyll cells – photosynthesis. Nerve cells – transmit information in the form of electrical impulses. Red blood cells – transport oxygen. Sperm and egg cells – fuse. 2. This "Selectively Permeable" membrane regulates what passes into and out of the cell. 3. The cell membrane is a fluid mosaic of proteins floating in a phospholipid bilayer. 4. The cell membrane functions like a gate, controlling which molecules can enter and leave the cell. 5. The cell membrane controls which substances pass into and out of.

The IGCSE curriculum allows the students to take a minimum of 5 and maximum of 14 subjects. The IGCSE ‘core’ curriculum consists of a First Language, Second Language, Mathematics, and one or more subjects in the area of science. English, Mathematics, and the Sciences are the IGCSE Core subjects. TRANSCRIPT. IGCSE Complete Chemistry. Notes. Refined and cleared by KmQ! :D By: Abdulla Al Zaabi. Unit 1: States of matter Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. The cell membrane also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus, it helps to support the cell and maintain its shape. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.

Growth - developing. 1. Similar cells are organised into tissues. Tissue - group of similar cells that work together to carry out a particular function. eg: plants - xylem tissue (transporting water and mineral salts) and phloem tissue. 130 hours for Cambridge IGCSETM courses.

The membranes have a common basic structure which regulates the movement of materials in and out of the cells. The cell membrane is made up of a phospholipid layer sandwiched by two protein layer (it is a lipoprotein layer) the overall thickness of the cell membrane is about 7.5 nm thick.

DIFFUSION MOVEMENT OF MATERIALS IN AND OUT OF CELLS Cell respiration shows the need for cells to be able to take in certain substances from their surroundings, such as. IGCSE Biology Lesson: Transport in Plants. Transport is the means by which we organisms transport the things we need to the parts of us that need it - energy for instance, or water. Our leg muscles need energy to move and our whole bodies need to remain hydrated, yet they are not near our stomachs. Hence we have a complex circulatory system. answer choices The movement of materials across the cell membrane that requires NO ENERGY from the cell. The movement of materials through (or across) the cell membrane The ability of the cell membrane to allow some things to pass through while preventing other things from passing through. Cell Organelles Definition. Cell organelles are specialized entities present inside a particular type of cell that performs a specific function. There are various cell organelles, out of which, some are common in most types of cells like cell membranes, nucleus, and cytoplasm. However, some organelles are specific to one particular type of cell. In and Out of Cells. Water is the main component of all cells. We find water in the cytoplasm and in cell sap. This water contains many dissolved substances and these substances plus the water enter and leave the cells through the cell membrane. The cell membrane allows certain particles through it but it blocks the passage of others. A normal cell has a high concentration of potassium on the inside and a low concentration of potassium on the outside. Also, a normal cell has a low concentration of sodium on the inside and a high concentration on the outside. Yet, the net movement of potassium is into the cell and the net movement of sodium is out of the cell. Paper 1 (4BI1/1B) Paper 1. Unknown date. Assesses the content that is not in bold and does not have a ‘B’ reference. Questions may come from any topic area across the specification. A mixture of different question styles, including multiple-choice questions, short-answer questions,calculations and extended open-response questions. The cell membrane in a living cell controls the movement of substances (in this case a red pigment) into or out of the cell. Boiling kills the cell by denaturing its enzymes, and the cell membrane loses its ability to control the loss of pigment. 3.
