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!

Key- bacteria come in all shapes and sizes

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.

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

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

BASIC BACTERIA SKETCH

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

Can you see different types of bacteria?

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

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

Reproduction KEY- WHEN BACTERIA HAVE ENOUGH FOOD, THE RIGHT TEMPERATURE, AND OTHER SUITABLE CONDITIONS THEY THRIVE AND REPRODUCE FREQUENTLY http://app.discoveryeducation.com/search?Ntt=BACTERIA&N=4294939055

List 3 types of helpful bacteria and what they do 1. 2. 3.

Bacterial reproduction copy and label

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
