Biology Unit 1 Flashcards
What is the name of grouping together different organisms?
Classification
What is the importance of grouping organisms together?
So the species won’t be in a big mess, making it hard to find a species when we need to…
What is a vertebrate?
An animal with a backbone.
What are the names of the 5 groups of vertebrates?
mammal, fish, birds, reptiles, amphibians
What are the different features of fish
Fish: have wet scales, live in water, have fins to move, breathe using gills
What are the key features of vertebrates?
They have a backbone.
What is the meaning of the word invertebrate?
An organism without a backbone.
What are the names of the 8 or 11 main invertebrate groups?
Arthropods Molluscs/Mollusks Echinoderms Cnidarians Sponges Annelids Flatworms Roundworms
Underneath arthropods: crustaceans insects arachnids Myriapods (centi and millipedes)
What are the features of: Arthropods (crustaceans, insects, arachnids, centipedes and millipedes)
jointed legs
bodies in sections
thick, hard exoskeleton
Crustaceans: 5-7 pairs of legs, chalky shell,they might have pincers
Insects: 3 PAIRS of legs, body in 3 sections,2 pairs of wings attached to thorax, compound eyes(i dun think that bit will be on the test though-aw)
Arachnids: 4 PAIRS of legs, body in 2 sections
Myriapods: Many pairs of legs, many body sections
What are the features of: Molluscs
Fleshy muscle for moving
Example: Snail
What are the features of: Echinoderms
Bodies in five parts, spiny outer covering
Example: Starfish
What are the features of: Cnidarians
Thin, sack like bodies, tentacles
Examples: Jellyfish, coral
What are the features of: Sponges
Bodies of loosely joined cells
can someone put an example?-aw
nope, can’t find any that aren’t in latin -hoi
What are the features of: Annelids
round worm-like bodies, bodies in sections
Examples: ragworms, earthworms, leeches
What are the features of: Flatworms
Flat, worm-like bodies
Example: Tapeworms
What are the features of: Roundworms
Thin, round, wormlike bodies, with no sections
What is the meaning of the word arthropod?
An invertebrate animal with jointed legs, and bodies in sections.
What groups are arthropods divided into?
Insects, crustaceans, arachnids and Myriapods
okay in the target sheet the next questions are:
Know how to spot differences/similarities between organisms.
IDK i’m too lazy to write a whole essay on how you do that.
SKIN COLOR, TEXTURES, HABITATS
What are grouping similar organisms called?
Classification
What features are useful for grouping organisms and which are not?
USEFUL:Body covering, eggs or not
NOT USEFUL: idk, do they poop rainbows
How do you use and produce dichotomous keys?
Those are the:
Does the bird have a long leg?
Yes—————————–No
Yes: it is a this No: Does it poop rainbows?
Yes——————————————No
Yes: It is not a unicorn
no: it is not a unicorn
What is variation?
a change or slight difference in condition, amount, or level, typically within certain limits.
(Varying features in a certain species)
Where does variation occur?
IN EVERY SPECIES I THINK
What are the names of areas where organisms are found?
Habitat/ecosystem
Know that organisms are adapted to where they live
THIS IS AN ANSWER
How are some organisms adapted to living in different habitats?
Figure this out yourself.
Examples:
Long fur in cold environments.
What are some adaptations for living in hot and dry, cold and underwater areas?
Hot and dry: long ears to lose heat, short fur
Cold: Long fur, layer of fat (it’s not blubber), small ears to conserve heat.
What changes happen in an environment?
Daily changes: Temperature change, amount of light
Seasonal: Temperature, amount of light, wind, amount of water.
How do organisms respond to daily changes?
Sleep at night, open flowers in different times, sleep in the morning, stuff like that.
How do plants respond to seasonal changes?
Protect buds, shed leaves
What are the meanings of the words predator, prey, herbivore and carnivore?
Predator: An animal that preys on others.
Prey: An animal that is hunted and killed
Herbivore: Only eats plants
Carnivore: Only eats meat
Omnivore: Eats both plants and meat
What are some adaptations of predators?
Long legs to run faster, sharp claws, teeth, beak, better senses (eyesight, scent, hearing) camouflage?
What are some adaptations of prey?
Camouflage, better senses, long legs to run faster.
How are animals adapted to their source of food?
bees and butterflies have long tongues to suck nectar
big cats have sharp teeth, sharp claws, good senses
What do food chains and webs show?
What organism eats what, and what it is eaten by
Flow of energy
(Thx aw, that’s really important)
What are the words used to describe the different levels in a food chain?
Producer Consumer Predator Top predator (or you can say all the primary, secondary and tertiary stuff if you want)
What equipment is used for sampling?
Quadrat, sweep net, pooter
What are some sampling methods?
Use a Quadrat to ‘cut out’ a piece of ground in a habitat and note how many organisms live in that habitat
How do you estimate population sizes?
Take some measurements about how many organisms live in a particular area using a quadrat. Get an average number then yup k.
How do people study habitats?
IDK
if it comes up in the test just write the sampling stuff.
How do you follow instructions? IDK WHY IT WAS ON THE TASKSHEET
i don’t think i can tell you that btw this was on the task sheet YOU JUST FOLLOW IT PPLL snoopy out
How do you use a quadrat?
A quadrat is a square that can be placed randomly over an area so plants can be counted
Also it’s Lara’s Necklace
How do you sample randomly?
Turn to page 92 of ur workbook im not gonna write it here takes too much effort
What are the features of amphibians?
Amphibians: Moist skin, lay eggs in water, eggs coated in jelly
What are the features of birds?
Birds: Feathers, eggs have a hard shell, warm blooded, have wings
What are the features of mammals?
Mammals: Hair, give birth to live young, produce milk, warm blooded (4 limbs, have ears- i dont think that will b in the test but yea- aw)
waaaaaaaaaaaaaait 4 limbs? dolphins: 2 flippers, 2 sides of tail? -hoi
What are the features of reptiles?
Reptiles: Dry scales, eggs have a leathery waterproof shell,cold blooded
How do animals respond to seasonal changes?
Hibernate in winter, wake up in summer, shed fur in summer and winter, migrate…Hibernate in winter, wake up in summer, shed fur in summer and winter, migrate…
How do you spell our teachers name?
Lucilla Lau
YES YOU NEEDED TO KNOW THIS YOU MIGHT NEEDA WRITE IT
What does ‘relationship’ mean?
How one thing effects another
What does it mean for two animals to be in the same ‘species’?
They can breed
What does the word Species mean?
An organism that can reproduce and give rise to fertile offspring.
