What is a cell? Cells are the building blocks of life.
Tissue A group of similar cells working together. Cells live with other cells like them in groups called tissues. Cytoplasm, cell membrane, organelles, nucleus. Jelly‐like stuff in the cell surrounded by the cell membrane. The cell membrane lets good stuff in and bad stuff out. Structures in the cell that do all the work that the cell needs to do like make proteins, turn food into energy and get rid of wastes (lysosomes and peroxysomes). Parts of a cell Cytoplasm Cell membrane Organelles Name____________________ Cells Date_____________________ The Cell’s Brain Eukaryotic cells Nucleus Prokaryotic cells Specialized cells (give examples) Cell Wall Cell Size Genetic material – DNA and RNA, or genes. The genetic material of eukaryotic cells are surrounded by a membrane. The genes and the membrane surrounding them form an organelle called the nucleus. Genetic material in prokaryotic cells floats free in the cytoplasm. They are not surrounded by a membrane. Bone cells – star shaped. Muscle cells, stretchy. Nerve cells very long. Bacteria have hairs around to help them move. Red blood cells have a bowl. Plant cells are surrounded by a rigid cell wall that maintains their shape. Range from microscopic to over a meter long. F, Lysosomes & Peroxysomes

Cell Structures Date_____________________ It carries the daily activities like energy consumption, protein production and waste management. Cell membrane Flexible, forms the outer layer of a cell. Regulates the chemical balance of the cell by deciding what gets in and what stays out. Nucleus The command center of the cell. The boss that hands out orders to the other cell parts. Guided by the cell’s DNA. DNA The cell’s DNA contains all of your body’s instructions for life. A mixture of chemicals and water inside the cell membrane. It flows around the cell carrying structures called organelles. Float in the cytoplasm and do different jobs. Cytoplasm Organelles Mitochondria Lysosomes Vacuoles Break down food and release energy.
Break down food, cell waste and worn out cell parts. Storage organelles that hang onto water, waste products and food until they are needed. Answer the following using your own brains: What is structure?______________________________________________________ ________________________________________________________________ What are some of the structures that make up a city like Manila? ___________________________ _______________________________________________________________, What would Manila be like without those structures? __________________________________ ________________________________________________________________ What would life be like without the structure that cells provide? ____________________________ ________________________________________________________________ Why do cells need organelles? ______________________________________________ ________________________________________________________________ Now, get the above checked for completion, then use the answer key to make corrections in red pen. Completion Always (100%) Usually (88%) Somewhat (76%) Rarely (64%) and Accuracy Exemplary = 5 points Proficient = 4.4 points Developing = 3.8 points Emerging = 3.2 points Is it complete? Is it accurate?
