Q

Who introduced the taxonomy system that became the basis for the system we use today and why?

A

Carolus Linnaeus
Recognized that little information was available about how to classify plants / saw a need for a universal classification system to communicate with scientists all over the world.

25
What are the five kingdoms of living things we use today?
``` Plantae Anamalia Protists Fungi Monerans ```
26
Why is the triangle written upside down?
Because as you move down the triangle, fewer organisms are included / more and more specific
27
Which word is the genus? | Which word is the species?
The first word. | The second word.
28
What are three ways that organisms are often named?
Prominent feature Location they are found Scientist who discovered them
29
How do you know which organisms are most closely related?
They both have the same exact layers on the table except for their species.
30
What is ecology?
The study of interactions between organisms and their environment.
31
What are the rules for scientific naming?
Name are always in Greek or Latin (no mixing or matching) Genus name is 1st, species name is 2nd First letter of genius is capital (all rest is lowercase) Typing = whole thing in italics Writing = whole thing is underlined
32
What are the 7 layers of classification?
``` Kingdom Phylum Class Order Family Genus Species ```
33
When was the microscope invented?
Early 1600’s.
34
What does the word “compound” mean when referring to the microscope?
2 lenses (one in eyepiece, one in objective)
35
What do ALL insects have in common?
``` 3 body parts = head, thorax, and abdomen 6 legs 4 wings Antennae Exoskeleton ```
36
How can an insect be a “good guy” or a “bad guy”?
“Good guy” = honeybees = pollinate flowers and many food crops, make honey “Bad guy” = mosquitos = spread disease such as malaria and yellow fever Grasshopper = destroy entire fields of crops
37
Ho do parasitic wasps help our world?
They lower the pest population.
38
What major discovery of biology did Robert Hooke make while using his microscope?
He discovered plant cells.
39
What major contributions to the development of the microscope did Antony van Leeuwenhoek make?
He made lenses that were much more clearer.
40
What difference was there between Hooke’s and van Leeuwenhoek scopes?
``` Hooke’s = blurry, compound Leeuwenhoek’s = clearer, it could magnify more, one lens ```
41
What are parts of the microscope?
Nose piece = rotates to change the magnification Objective lens = provides a range of magnification Stage = supports the slides Diaphragm = adjust the amount of light that passes through Light = sends light through the whole Eyepiece = contains a 10 X lens Arm = supports the upper part of the microscope Stage clip = helps to hold slides in place Coarse adjustment knob = raises and lowers stage Fine adjustment knob = raises and lowers stage a tiny distance Base = supports the microscope
42
How to calculate total magnification?
Power Eyepiece Obj. Lense Total mag. Low(red) 10X 4X 40X Med.(yellow) 10X 10X 100X High(green) 10X 40X 400X
43
Diameters of fields for low, medium, and high.
``` Low = 4.5 mm Med = 1.5 mm High = 0.5 ```
44
What is amazing about Lumbirculus variegatus?
If you cut it in half, it turns into two live worms.
45
In what environment are they usually found?
Shallow edges of ponds, marshes, and lakes in North America and Europe.
46
How many segments does a mature blackworm generally have?
150 - 250 body segments
47
How can you tell regenerated segments from original segments?
Usually smaller and paler than original.
48
Describe how a black worm propels it self.
By “twisting” it’s body through the water in a corkscrew fashion.
49
Why does it live in shallow water? Why is there a danger for the black worm in the situation?
To stretch its tail to the surface to exchange oxygen and carbon dioxide. Exposes the black worm’s tail to their enemies.
50
What are photoreceptors and how do they help the black one?
Photoreceptors = nerve cells that detect shadows, vibration, and touch. “Activates” special rapid-escape reflex.
51
What is the scientific name for the common earthworm?
Lumbricus terrestris
52
What is the clitellum and what is its significance for the earthworm?
Clittellum = light colored bulge on body | If it’s cut in half, the part with that clitellum can only regenerate.
53
Describe the setae and their function.
Setae = tiny hairs to help them grip on the soil
54
How do earthworms dig? How does this help plants grow?
1. Eat tiny bits of soil, decaying leaves, bacteria, and microorganisms. 2. Grind and mix food with digestive systems. 3. Expel their waste, castings, which is nutrient rich soil. Tunnels give air and easy access to the roots of plants.
55
Black worm anatomy
``` Anterior = Head end Posterior = tail end Digestive tract Blood vessel Chaetae ```
56
Would a habitat be considered part of the community or the ecosystem?
Part of an ecosystem. | Because there are many different habitats or homes in an ecosystem.
57
List ways in which ecosystems can change. Why does this change affect the organisms living in this habitat?
``` Ponds dry up Forest fires Trees fall Organisms become extinct Human’s Because they have to adapt to it. ```
58
What effects can natural processes and human interactions have on the planets ecosystems, habitats, communities, and populations?
Air pollution = tree leaves fall Construction = leaving a stream’s water stagnant and foul Droughts = soil get parched and cracked
59
How can populations of organisms in an ecosystem be categorized?
By how they eat.
60
Give 3 examples of autotrophs.
Plants Algae Some bacteria
61
What are organisms that eat other organisms called in a ecosystem? Why do they have this name?
Consumers | Because the eat other organisms.
62
Give 3 examples of heterotrophs.
Humans Fungi Most bacteria
63
What does a decomposer eat?
Dead organisms | Waste material
64
Give 3 examples of a decomposer.
Millipedes Mushrooms Molds
65
How do decomposer help the ecosystem?
They help break down dead organisms and return their molecules to the ecosystem.
66
Could heterotrophs survive without autotrophs? Why or why not?
No, because heterotrophs eat autotrophs.
67
Could autotrophs survive without heterotrophs? Why or why not?
Yes, because they make their own food.
