support and movement
- support in plants
- palm trees
- fewer leaves= less surface
area and resistance to wind
- flexible trunks= bend with
wind to cope with force
- fewer leaves= less surface
area and resistance to wind
- cells
- gained water=TURGID
- lost water=FLACCID
- gained water=TURGID
- palm trees
- the skeleton
- bones
- support=hold us up
- movement=attached to muscles
- protection of internal organs
- protection of blood cells by the bone marrow
- calcium phosphate=
hard brittle outer
layer for support
- collagen=flexible and bendy for strength
- support=hold us up
- joints
- hinge joint
- ball and socket joint
- saddle joint
- hinge joint
- bones
- swimming
- fish movement
- rocking/pitching= up and down
- rolling= swaying
- yawing= side to side
- rocking/pitching= up and down
- fish fins
- pectoral and pelvic fins= prevent rock
- dorsal, anal and adipose fins= prevent roll
- caudal fin= prevents yaw
- pectoral and pelvic fins= prevent rock
- fish muscles
- muscles spring back moving the caudal
fin side to side, driving the fish forward
- the right side has to contract
to bend the fish to the right
- muscles spring back moving the caudal
fin side to side, driving the fish forward
- fish movement
- speed
- relationship between
length, stride and speed
- length and speed= longer legs, faster speed
- length, stride and
speed= taller- bigger
stride- faster speed
- length and speed= longer legs, faster speed
- cheetah
- oversized lungs= store more oxygen
- oversized heart= pumps more blood faster
- big stride length= less tiring- don't need
as much power of energy to get to places
- light body mass=doesn't have
to support much weight
- streamline body shape= prevents friction
- oversized lungs= store more oxygen
- relationship between
length, stride and speed
