Explanation:

• A. Green Pigment used for photosynthesis in the leaves of plants: Chlorophyll is the green pigment in plant leaves that is crucial for photosynthesis.
• B. The process that converts light energy to chemical energy: Photosynthesis is the process where light energy is converted into chemical energy (glucose).
• C. The process that converts food into usable energy (ATP): Cellular Respiration breaks down food (glucose) to produce ATP (usable energy).
• D. Maintenance of constant internal conditions within an organism: Homeostasis is the maintenance of a stable internal environment in an organism.
• E. Water hating part of the cell membrane: Hydrophobic (water - hating) parts of the cell membrane (like the tails of phospholipids).
• F. The cell membrane can regulate which materials are able to pass through; therefore, it is described as being: Selectively Permeable means the membrane allows certain substances to pass while restricting others.
• G. Movement of molecules from areas of high to low concentration: Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.
• H. Organism that eats other plants or animals for energy: Heterotrophs obtain energy by consuming other organisms.
• I. Water - loving part of the cell membrane: Hydrophilic (water - loving) parts of the cell membrane (like the heads of phospholipids).
• J. Transport of water molecules from areas of high to low concentrations through a semi - permeable membrane: Osmosis is the diffusion of water across a semi - permeable membrane.
• K. A process that does not require oxygen to make energy: Anaerobic processes (like some types of fermentation) do not need oxygen to produce energy.
• L. Organisms that can produce their own food: Autotrophs (like plants) can make their own food through photosynthesis.
• M. Large or charged molecules move across the cell from higher to lower concentration through a protein channel embedded in the cell membrane: Facilitated Diffusion uses protein channels to move large or charged molecules down their concentration gradient.
• N. Energy is required to move particles across a cell membrane against a concentration gradient: Active Transport requires energy (usually ATP) to move substances against their concentration gradient.
• O. Expelling big molecules out of the cell by active transport: Exocytosis is a form of active transport where cells expel large molecules.
• P. Moving large molecules into the cell by active transport: Endocytosis is a form of active transport where cells take in large molecules.
• Q. Specialized structures within a living cell: Organelles are specialized structures in a cell that perform specific functions.
• R. A special type of lipid that makes up the cell membrane: Phospholipid is the main lipid component of the cell membrane.
• S. A process that requires oxygen to make energy: Aerobic processes (like aerobic cellular respiration) require oxygen to produce energy.
• T. Does not energy to transport molecules across cell membrane: Passive Transport (like simple diffusion and facilitated diffusion) does not require energy.
