The Study of Life

Biology: is the study of living and once-living things.



Light microscope: light passes through the object being looked at and then through two or more lenses.

 

Stereomicroscope: is used fo viewing large objects and things through which light cannot pass, such as insect.



International System of Units: is a measuring system based on units of 10.



Meter: the SI unit of length.



Volume: is the amount of space a substance occupies.



Kilogram: the SIunit of mass.



Celsius: scientific measure of temperature.



Scientific method: the steps to solve problems.



Hypothesis: is the stament that can be tested.



Experiment: testing a hypothesis using a series of steps with controlled conditions.



Variable: is something that causes the changes observed in a experiment.



Contol: is a standard for comparing results.



Data: are the recorded facts from measurements of experiment.



Theory: is the hypothesis that has beeb tested again and again by many scientist with similar results each time.



Thechnology: the use of scientific discoveeries to solve everyday problems.

Potist and Fungi

Protozoan: are one-celled animal-like organism with nucleus.



Cilia: are short hairlike parts on the surface of the cell.



Sporozoans: are protozoans that reproduce by forming spores.



Spores: are special cells that develop into new organism.




Algae: are plantlike protists.



Multicellular: means that an organism has many different cells that do certain jobs for the organism.



Slime molds: are funguslike protists that are consumers.



Hyphae: the bodiesnof mostnfungi are made of network of threadlike stucture.



Sporagium fungi: are fungi that produce spores in sporagnia.



Sporangia: are stuctures, found on the tips of hyphae, that make spores.



Club fungi: fungi with club-shaped parts that produce spores.



Sac fungi: produce spores in saclike stuctures.



Budding: is reproduction in which small part of the parent grows into a new organism.



Mutualism: a living arrangement in which both organism benefit.



Lichen: is a fungus and an organism with chlorophyll that live together.

Virus and Monerans

1. Virus: ia made of chromosonmes-like partsurrounded by protein coat.
2. Host: is an organism that`provides food for a parasite.
3. Parasite: is an organism that lives in or on another living things and get food from it.
4. Interferon: is a chemical substance that interfers with the way viruses reproduce
5. Vaccines: are substance made from weakened or dead viruses
6. Bacteria: are very small, one celled monerans.
7. Clony: is a group similar cell growing next to each other that do not depend on each other.
8. Capsule: some bacteria have a sticky outer layer.
9. Flagellum: some bacteria move with long, whiplike thread.
10. Fission: is the process of one organism diving into two organism.
11. Asexul reproduction: is the reproduvtion of a living thng from only one parent.
12. Endospore: is a thick-walked sturcutre that forms inside the cell, enclosing all nuclear material and some cyotplasm.
13. Saprophytes: areorganism that use deadmaterials for food.
14. Descomposers: are living things that get their food from breaking  down dead matter into simple chemical.
15. Koch `s postulates: are steps for proving that diases is caused by a certain microscopic organism.
16. Communicable diases.are ones that can be passed from one organism to another.
17. Antibiotics: are chemical substance that killor slow the growth of bacteria.
18. Biotechnology: is the use of ling things to solve practical problems.
19. Pasteurization: the process to heating milkto kill harmful bacteria.
20. Blue- green bacteria. are small, one-celled monerans that contain chlorophyll and can make their own food.
