Coordination Flashcards
(31 cards)
What are the 2 types of tropisms
Phototropism - plants response to light
Gravitropism -plants response to gravity
What are the three plant hormones
Auxins - promote cell elongation in shoots and inhibit cell elongation in roots
gibberellins-initiate seed, germination, flowering and growth of fruit
Ethene - control, cell division and ripening of fruits
How do you answer a question that I asked you to plant an investigation?
Step one independent variable step to dependent, variable step three controlled, variable step for control, set up step five repeat investigation step, six appropriate equipment in points one to 4
What are auxins used for
Used as selective weed killer so growth of weed is controlled by farmers using oxygen is to keep yields high
Used as rooting powder.
Used to cloned plants.
What is ethene used for?
Controls cell division of ripening of fruits, during storage and transport production of Ethene is inhibited to dela ripening of fruits.
During display artificially produced Ethene gascan be released to speed up fruit ripening
What is giberelins used for
End seed dormancy
Promote flowering
Increase fruit size
What are the 4 lobes
Frontal lobe
Parietal lobe
Temporal lobe
Occipital lobe
What does the cerebral cortex control?
Consciousness memory, intelligence language
What does the cerebellum control?
Muscle coordination and movement
What does the Medalla control?
Unconscious activities, breathing
What are the 10 parts of the eye
Suspensory ligament
Cornea
Iris
Pupil
Lens
Ciliary muscle
Sclera
Retinal.
Fovea
Optic nerve.
Function of cornea
Refract light bends it as it enters the
Function of iris
Controls how much light enters the pupil
Function of lens
Further refracts light to focus it onto the retina
Function of retina
Contains light receptors
Function of optic nerve
Carries impulses between the army and brain sensory neuron
Function of pupil
Holes that allows light to enter the eye
What 2 things surround the pupil
Circular muscle
Radial muscle
In dim light what happens to your eye
1light receptors cells detect darkness.
2 radial muscle contract
3 circular muscle relax
4pupil dilates and widens
5 more light enters eye better vision
In bright light, what happens to the eye
1light receptor cells detect brightness
2 radio muscle relax.
3 circular muscles contract.
4 pupil constricts and narrows
5 less light enters the eye to avoid retina damage
What happened to your eye focusing on near objects
Cilary muscles contract.
Suspensory, ligaments loosen
Lens becomes thicker and refracts, light rays, more strongly.
Happens to your eye when focusing on far objects
Ciliary muscles, relax
Suspensory, ligaments appetite.
Lens is poured Finn, and only slightly refracts light rays.
What is myopia and what are the causes of it?
Short sightedness
Courses or lens is too thick and curved.
I will is too long.
Light is focused in front of the retina.
What is hyperopia and what are the causes of it?
Long sightedness
Causes are eyeball to short
Light is focus behind the retina.
