BENCHMARK REVIEW

As a system I am responsible for breaking down large food molecules into smaller nutrients the body can use. DIGESTIVE 2 types of digestion – mechanical and chemical Where do each take place?

I add surface area to the small intestine to slow down the food’s passage and to absorb nutrients. VILLI Finger-Like projects, increase surface area, slow down passage of chyme, increases chance of absorption and digestion

Endoplasmic Reticulum has a similar job in individual cells As a system I an responsible for moving materials through out your body. CIRCULATORY Endoplasmic Reticulum has a similar job in individual cells

Large molecules have chemical bonds broken, creating new substances My salivary glands secrete saliva which begins ________ digestion of starches into sugars. CHEMICAL Large molecules have chemical bonds broken, creating new substances

ASEXUAL Less diversity, less variety in a population My process produces clone and requires only 1 parent for reproduction (1 word) ASEXUAL Less diversity, less variety in a population

Food is broken/cut/compacted into smaller pieces, physical change Although I am teeth I act like a simple machine (wedge) and perform _________ digestion on your food. MECHANICAL Food is broken/cut/compacted into smaller pieces, physical change

RESPIRATORY Gas exchange takes place between alveoli and capillarys As a system I am responsible for exchanging oxygen and carbon dioxide gasses. RESPIRATORY Gas exchange takes place between alveoli and capillarys

I disproved the idea of spontaneous generation. (2 WORDS) CELL THEORY All living things are made of cells Cells are the basic unit of living things Cells come form other living cells Organisms can extract energy from their surroundings/environment

I am the elastic structure in your lungs where gas exchange takes place ALVEOLI

All my kids are the same, some use the term clone, but I prefer: UNIFORM Asexual reproduction – 1 parent

I am the basic unit of life. CELL Atoms are the basic unit of matter

RESPIRATION Chemical reaction that converts glucose into ATP (energy) Cellular ___________ takes place in the mitochondria of all cells. The result is ATP an energy molecule. RESPIRATION Chemical reaction that converts glucose into ATP (energy)

As I increase so does the health and sustainability of my ecosystem. BIODIVERSITY Variety of all organisms in an ecosystem Sustainability = ability to maintain and continue

ENDOCRINE Helps control body functions using hormones I have to play second banana to the nervous system, but at least I get to help control and coordinate your body. ENDOCRINE Helps control body functions using hormones

BILE Stored in the gall bladder, released into small intestine I help with the mechanical digestion of lipids and am produced by the liver. BILE Stored in the gall bladder, released into small intestine

I am semi-permeable and referred to as the gate keeper if you do not know the “password” you are not getting in or out. (2 words) CELL MEMBRANE

Usually “imported” by humans, tend to “push” out native species As a species I am not to blame if I edge out native species and decrease your biodiversity. You have tagged me as an _________ species INVASIVE Usually “imported” by humans, tend to “push” out native species

Not all producers are plants that’s why we prefer the term: AUTOTROPH Algae, phytoplankton Use photosynthesis and chemosynthesis to produce food

ONLY in plants site of photosynthesis = production of glucose I capture the sun’s radiant energy and transform it into chemical energy. CHOLORPLAST ONLY in plants site of photosynthesis = production of glucose

I am a genius and in command of my SMALL world NUCLEUS Location of DNA/Chromosomes – contains all information about how an organism is built and functions

SEXUAL Greater diversity of within species and populations 2 parents By using this method of reproduction we guarantee a greater mix of genetic material and a greater biodiversity. SEXUAL Greater diversity of within species and populations 2 parents

All ecosystems want to continue indefinitely so we do all we can to maintain our: SUSTAINABILITY Ability to maintain and continue Species able to survive indefinately

Our offspring are not uniform they are very….. DIVERSE Sexual reproduction, 2 parents, combination of different genetic material increases the gene pool

PHOTOSYNTHESIS Takes place in chloroplasts of autotrophs I am the process that takes in sunlight, water, and carbon dioxide to produce glucose and oxygen. PHOTOSYNTHESIS Takes place in chloroplasts of autotrophs

Plant cells like by rigidity because I provide them with structure and support CELL WALL ONLY in plants, made of cellulose – cell membrane will pull away from cell wall when turgor pressure is lost

WORK Unit of measurement = joule (j) Accomplishment means you have applied a force and moved an object some distance. I am calculated by multiplying: F x D WORK Unit of measurement = joule (j)

Helps maintain homeostasis by helping to control body temperature My largest organ is the skin and I act as a barrier to protect the body. I am the __________ system. INTEGUMENTARY Helps maintain homeostasis by helping to control body temperature

Although I am part of the digestive system no digestion takes place, only absorption of water and dissolved nutrients. LARGE INTESTINES NO DIGESTION. E. coli live here and “feed” on undigested materials producing vitamin K which we need = symbiosis / Mutualism

Nothing can SUCK because I am defined as a push or a pull FORCE F = m x a Unit of measurement = newton (N)

DNA Makes up our Chromosomes holds our genetic code I store all the data that codes for who you are and how you work. I am located in the nucleus. DNA Makes up our Chromosomes holds our genetic code

I am a special key that can not open any locks but I can help you identify an organism. DICHOTOMOUS Uses a series of yes or no questions Scientific name = genus species = always in latin

My job is to filter blood to remove waste. KIDNEY

I am the unit of measurement for work. JOULE

Although I am small I have a critical job. I produce proteins for you. RIBOSOMES I can be “free floating” in the cytoplasm or attached to the endoplasmic reticulum

Without my wave like contractions food could not move through your digestive system. PERISTALSIS

I am responsible for producing ATP during cellular respiration. MITOCHONDRIA ATP = energy molecule “Power House”

My system’s main go to worker is the kidney, without me you would become very toxic. EXCRETORY Removes liquid waste from the body – filtered and collected in the kidney > passes thru ureters to the urinary bladder then out of body thru the urethra

I am a genius and in command of my SMALL world NUCLEUS

Omnivore, Carnivore, Herbivore we are all a type of….. HETEROTROPH Cannot make our own food we need to COMSUME other organisms to get food

Please keep me watered properly so that my vacuoles will stay full and maintain __________ pressure so I do not wilt. TURGOR Cell membrane will pull away from cell wall, cell will appear to “shrink” when turgor pressure is lost. Plants will wilt and eventually die if they do not receive adequate amounts of water

If you have one or more of me, I can increase your chance of survival. ADAPTATION

My ecosystem has been undergoing ________ succession due to a wildfire. SECONDARY

I am involved in a symbiotic relationship and help form soil. LICHEN

I am the driving force behind adaptations and is some times thought of as “Survival of the Fittest” (2 words). Natural Selection

I am a plant’s circulatory system responsible for transporting necessary materials through the plant. XYLEM

Every good ecosystem strives to become a _________ community. CLIMAX

Sure takes a long time to create an ecosystem when you are starting with nothing but a bunch of rocks. I guess that’s why they call it _______ succession PRIMARY
