7th Grade Bacteria Question Answer A chemical that can kill ONLY bacteria without harming the human body is called a(n) antibiotics What happens if you don't take all of your antibiotics The bacteria will become stronger and make you sicker What are the three shapes of bacteria rods, spirals, spheres Why are bacteria classified as prokaryotes? they have no nucleus What do bacteria form when conditions are bad? endospores Are bacteria multicellular or unicellular? unicellular What is the name of the whiplike tail that helps some bacteria move around? flagellum What are the names of the two bacteria kingdoms? eubacteria and archaebacteria Type of bacteria that are found everywhere eubacteria are the oldest organisms on earth and they live in extreme conditions such as sewers archaebacteria where two parent bacteria combine their genetic material to produce a new bacteria that differs from both parents sexual reproduction where one parent bacteria reproduces a new bacteria that is identical to that parent. asexual reproduction organisms that have a nucleus eukaryotes organisms that do not have a nucleus prokaryotes Are bacteria living organisms? yes Are bacteria heterotrohps or autotrophs? they can be both Are bacteria prokayotes or eukaryotes? prokaryotes List some ways bacteria are helpful used to mark certain foods, some produce heat, help keep your body healthy, decompose dead organisms and trash, clean up oil spills List some ways bacteria are harmful cause food to spoil, some make you sick, can cause really bad smells Are bacteria named using binomial nomenclature? Yes...because bacteria are living organisms

Question 7 What is the name of the whiplike tail that helps some bacteria move around? flagellum

Flap 1	Flap 2
cellulose	chemical compound made by plants out of sugar
cuticle	waxy, protective layer that covers the stems, leaves and flowers of many plants and prevents water loss
vascular plant	plant with tubelike structures that move minerals, water and other substances throughout the plant
nonvascular plant	plant that absorbs water and other substances directly through its cell walls
rhizoids	threadlike structures that anchor nonvascular plants to the ground
stomata	tiny openings in a plants epidermis through which carbon dioxide and water vapor gases enter and leave a leaf
guard cell	pairs of cells that surround stomata and control their openings and closing
gymnosperms	vascular plants that do not flower
angiosperms	flowering vascular plants that produce fruit containing one or more seeds
xylem	vascular tissue that forms hollow vessels that transport substances, other than sugar throughout a plant
phloem	vascular tissue that forms tubes that transport dissolved sugar throughout a plant
cambium	vascular tissue that produces xylem and phloem cells as a plant grows
photosynthesis	food making process that takes place in the chloroplasts of plant cells
chlorophyll	green, light trapping pigment in plant chloroplasts that is important to photosynthesis
respiration	series of chemical reactions used to release energy stored in food molecules
auxin	plant hormone that causes plant leaves and stems to exhibit positive phototropism
tropism	positive or negative plant response to an external stimulus such as touch, light, or gravity
photoperiodism	a plant's response to the lengths of daylight and darkness each day
