2. Choose 4 Terms and define

3. THE BACTERIAL CELL KEY- THERE ARE BILLIONS OF BACTERIA ON EARTH.
KEY- THEY ARE EVERYWHERE. THERE ARE MORE BACTERIA IN YOUR MOUTH THEN THERE ARE PEOPLE ON EARTH
KEY- THEY ARE FOUND UNDER ROCKS, IN THE AIR, IN DEEP OCEAN VENTS, ON MOUNTAIN TOPS, AND ALL OVER YOUR BODY!

4. Key- bacteria come in all shapes and sizes

6. BACTERIAL CELL
KEY- THEY WERE DISCOVERED BY LEEUWENHOEK LOOKING AT SCRAPINGS FROM HIS TEETH
KEY- BACTERIA ARE PROKARYOTES
(CELLS WITHOUT A NUCLEUS).
KEY- THE GENETIC MATERIAL IN THEIR CELLS IS NOT CONTAINED IN A NUCLEUS.

7. Cont’d
KEY- A BACTERIAL CELL LACKS MANY OTHER STRUCTURES THAT CELLS HAVE LIKE MITOCHONDRIA AND GOLGI BODIES
MOVEMENT- SOME BACTERIA USE A FLAGELLUM (PLURAL FLAGELLA), A LONG WHIP LIKE STRUCTURE THAT HELPS A CELL TO MOVE

8. BASIC STRUCTURE OF BACTERIA (COPY)

9. IDENTIFY FLAGELLEM

10. SIZES AND SHAPES KEY- BACTERIA VARY GREATLY IN SIZE
KEY- MOST BACTERIAL CELLS HAVE ONE OF THREE BASIC SHAPES: SPHERICAL, RODLIKE, AND SPIRAL

11. Could this be Bacteria?

17. BASIC BACTERIA SKETCH

18. OBTAINING FOOD AND ENERGY
KEY- BACTERIA MUST HAVE FOOD SOURCE AND A WAY OF BREAKING DOWN THE FOOD TO RELEASE ITS ENERGY.
AUTOTROPHS- SOME BACTERIA ARE AUTOTROPHS AND MAKE THEIR OWN FOOD
EX- PLANT LIKE BACTERIA USE SUNLIGHT TO MAKE THEIR OWN FOOD

19. Can you see different types of bacteria?

20. HETEROTROPHS- BACTERIA THAT DOESN’T MAKE ITS OWN FOOD.
KEY- INSTEAD THESE BACTERIA CONSUME OTHER ORGANISMS OR THE FOOD ORGANISMS MAKE.
EX- THE BACTERIA THAT HELPS LEAVES DECAY ON THE FOREST FLOOR

21. RESPIRATION
RESPIRATION- IS THE PROCESS BY WHICH BACTERIA BREAKS DOWN FOOD USING OXYGEN FOR ENERGY

23. Reproduction
KEY- WHEN BACTERIA HAVE ENOUGH FOOD, THE RIGHT TEMPERATURE, AND OTHER SUITABLE CONDITIONS THEY THRIVE AND REPRODUCE FREQUENTLY

24. List 3 types of helpful bacteria and what they do1. 2. 3.

25. Bacterial reproduction copy and label

26. REPRODUCTION KEY- THERE ARE TWO WAYS IN WHICH BACTERIA CAN REPRODUCE
1. ASEXUAL REPRODUCTION- A PROCESS THAT INVOLVES ONLY ONE PARENT AND PRODUCES OFFSPRING THAT ARE IDENTICAL TO PARENT.
2. SEXUAL REPRODUCTION- TWO PARENTS COMBINE THEIR GENETIC MATERIAL TO PRODUCE A NEW ORGANISM WHICH DIFFERS FROM BOTH PARENTS
