CELLS NAME STANDARDS FOR UNIT CELLS All living things are made of cells. All cells carry out similar functions; take in oxygen , give off carbon dioxide, make energy, reproduce) Identify structures and describe their function within the cells Most cells are unicellular. Identify common unicellular organisms in diagrams, photographic and/or microscopic slides Multicellular organisms have specialised cells. Identify various specialized cells in diagrams, photographic and/or microscopic slides Explore how the use of a microscope allows one to see cells in a variety of organisms The Work Most of the work will be done in this packet. There are 6 assessments in this unit. 1. Life Processes activity 2. The pond life activity 3. Virtual microscope activity 4. Types of organisms activity 5. Parts of a Cell activity 6. Brochure
All Living things do the same things 1. Make a list of things that are living and non-living in the picture below. LIVING NON LIVING 2. What makes something alive?
Movement • Respiration • Sensitivity • Growth • Reproduction • Excretion • Nutrition The 7 Life Processes Hello! I’m Mrs Gren. • Movement • Most of this is common sense. You can move around from place to place and so can most plants and animals. Animals move to: • find shelter, • escape from predators and other danger, • find food, • find a mate. • (Plants tilt or move to face the sun.) • Respiration Turning food into energy • Sensitivity is very important. How would you know if something was fit to eat if you could not smell or taste it? How would you escape danger? • Growth ------ we all do it. • Reproduction: making more of ourselves. • Excretion means getting rid of the poisonous waste products produced from the chemical reactions in our bodies. We breathe out carbon dioxide and we urinate. • Nutrition. We have to eat to provide the materials for growth, repair and to provide us with energy.
Refer to The Cell: The Hidden Kingdom 00:00—2:50 What is life? Where does life come from? Q. What’s the difference between Dr. Adam Rutherford and 18kg of carbon, a small canister of nitrgen, 50kg of water, some phosphorus, a small amount of iron and 20 other chemicals? A chemist would answer, ‘’Nothing.” 4. What would a biologist answer? We have sixty thousand billion of these. That is ; 60,000,000,000,000,000 !!!! 5. What are they? ANTON VAN LEEUWENHOEK . One thing he used his microscope for was to look at a drop of pond water. He was mazed to see tiny creatures! He described them and drew them carefully and sent his work to scientists in England. They thought he was crazy! But was he? Anton van Leeuwenhoek was born in the town of Delft, Holland, in 1632.He had a rather unusual background for a scientist, beginning in the cloth trade in Amsterdam, and then becoming City Chamberlain of his native town. became interested in the making of microscopes, however, and used them enthusiastically in his studies almost until his death in 1723.
Asm More about VAN LEEUWENHOEK Discuss in groups. Put in order. Which do you think made VAN LEEUWENHOEK a great scientist? • His curiosity • Invention of better lenses • Attention to detail • Skill—being a mastercraftsman Refer to The Cell: The Hidden Kingdom 4:45—12:27 Pond Micro-organisms Lab Enter Van Leeuwenhoek's Invisible World...... Using the digital microscope take a still of the organisms that you observe nder the microscope. Paste them into the the template slide show which you can dwnload from 5Cameron website. Match them to the organisms on the webpage above. There is a link on the website. Label the organisms and complete the information. This will be assessed. Print the rubric and hand in when you have put the finished slide show in the folder on dropbox.
Micro-organisms Complete the sentences below by filling in the gaps. A micro-organism is a creature too ____ to be seen by the naked eye, we need to use a microscope instead. Micro-organisms can be bacteria or fungi (but not viruses) and they live everywhere on Earth where there is _____ water. Micro-organisms are a very important part of food ____ and recycling nutrients in different ___-_____. Micro-organisms break down dead plant and animal material into nutrients which can then be absorbed again by plants. Without these nutrients the plants would die, and no plants = no animals or _____! The micro-organisms that break down dead plant and animal matter are called _______. We also have special bacteria in our ______ to help us digest food. Sometimes we eat healthy bacteria in yoghurts to help our _______. Micro-organisms Complete the sentences below by filling in the gaps.

Parts of a Cell Cell Membrane (orange) Mitochondria (red) Vacuole (light blue) Chloroplasts (light green) Cell Wall (dark green) Cytoplasm (yellow) Nucleus (purple) Flagella (brown) 2. When you finish choose some letter to label the cells; plant, animal, bacteria, virus 1. Color and label the parts of the cells as follows:
Uni-cellular & Multicellular Organisms • Some living things (organisms) are made of only one cell. These are called unicellular organisms. Algae, bacteria, paramecium and amoeba are examples of unicellular organisms. They carry out all the activities required to keep the organism alive: feed, move, reproduce, and excrete.Some living things are made of many cells, even millions of cells like us. These organisms are called multicellular organisms.Different Jobs for Different CellsMulticellular organisms are made up of millions of cells of different types. All the cells in your body are animal cells, but you have different types of animal cells in your body.These different types of cells in your body have very different jobs to do. As a result the cells in your body are different shapes and sizes.In multi-cellular organisms different cells do different jobs e.g. red blood cells and brain cells. There are many different types of cells in our bodies.Each type of cell has a special job to do.Cells which do one special job are called specialized.To Sum Up:A unicellular organism is made of only one cell (e.g. most pond life organisms, viruses and bacteria)........ A multi-cellular organism is made of many cells (e.g. plant cells and animal cells)
