4.7.1.4 Adaptations Flashcards
1
Q
How do adaptations help organisms?
A
- they allow them to survive in the conditions they live in
2
Q
What are the three different types of adaptations?
A
- structural
- behavioural
- functional
3
Q
What are structural adaptations?
A
- shape or colour of a part of an organism
4
Q
What are examples of structural adaptations?
A
- sharp teeth of a carnivore to tear meat apart
- camouflage, such as tan/brown colour of a lionesses coat to avoid prey from spotting her
- species in cold environments may have thicker layer of fat for insulation
5
Q
What are behavioural adaptations?
A
- the way an organism behaves
6
Q
What are examples of behavioural adaptations?
A
- individuals may play dead to avoid predators
- basking in the sun to absorb heat
- courting behaviour to attract a mate
7
Q
What are functional adaptations?
A
- involved in processes such as reproduction and metabolism
8
Q
What are examples of functional adaptations?
A
- late implantation of embryos
- conservation of water through producing little sweat
9
Q
What are extremophiles?
A
- organisms that live in environments which have extreme conditions
10
Q
What are examples of environments which have extreme conditions?
A
- high temperatures
- high pressures
- high salt concentrations
11
Q
What is an example of an extremophile?
A
- bacteria which live deep in sea vents where pressure is very high
12
Q
What are adaptations for a cold climate?
A
- smaller surface area to volume ratio to reduce heat loss
- lots of insulation (blubber, fur coat)
13
Q
What are adaptations for a dry climate?
A
- adaptations to kidneys so they can retain lots of water which produces very concentrated urine
- being active in the early morning and evenings when it is cooler
- resting in shady areas
- larger surface area to ratio to increase heat loss
14
Q
What are adaptations for plants?
A
- curled leaves to reduce water loss
- extensive root systems to take in as much water as possible
- waxy cuticle to stop water evaporating
- water storing tissue in stem
