Cell: Cell is basic unit of life which can able to replicate and maintain its species growth in this world.
6 Characteristics of Living Things: made of cells, reproduce grow and develop, respond to stimuli, require energy, have a lifespan, produce waste.
Cell Membrane: Separates cell from outside world.
Permeability: how much a membrane lets things go through
Concentration Gradient: Gradual difference of molecules (high to low)
Diffusion: movement of molecules from high to low concentration.
Osmosis: movement of water from high to low concentration.
Hypertonic: when it shrivels
isotonic: Stays the same.
Hypotonic: grows bigger.
Solutes: Salt, sugar
Prokaryotic Cell: Bacteria cells, no nucleus.
Eukaryotic Cell: animal and humans cells.
Cell Organelles: A membrane-bound compartment or structure in a cell that performs a special function.
Lysosomes: Lysosomes are small sac-like structures surrounded by a single membrane and containing strong digestive enzymes which when released can break down worn out organelles or food.
Ribosomes: Ribosomes make proteins
Cytoplasm: Organelles are found here and substances like salts may be dissolved in the cytoplasm.
Nucleolus: the brain of the nucleus. The nucleolus takes up around 25% of the volume of the nucleus.
Nucleus: The nucleus is the "control center" of the cell, for cell metabolism and reproduction
Endoplasmic Reticulum: network of membranous canals filled with fluid. They carry materials throughout the cell.
Vacuole: Vacuoles are fluid filled organelles enclosed by a membrane. They can store materials such as food, water, sugar, minerals and waste products.
Mitochondria: the mitochondria releases food energy from food molecules to be used by the cell. This process is called respiration.
Golgi Body: The Golgi Body temporarily stores protein which can then leave the cell via vesicles pinching off from the Golgi.
plasma membrane: Proteins are found embedded within the plasma membrane.
Chloroplast (only plants): Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
Cell Wall (only plants): he cell wall of plants maintains the shape of plant cells, supports and strengthens plants, resists water pressure, controls cell growth, regulates metabolic processes for the plant, acts as a physical barrier for the plant, stores carbohydrates and helps with cell to cell signaling.
photo synthesis: Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy.
