Flashcards in GRASSHOPER (Insects) Deck (21):
1

How many body parts does a grasshopper have (3)

3 Parts

  • Head
  • Thorax
  • Abdomen

2

Describe the head of a grasshopper (3)

2 antennae that are used to feel

3 simple eyes 2 compound eyes

3

Describe the mouthpieces for the grasshoppers and for what diet is it adapted? (2)

Chewing mouthpieces - adapted for herbivore diet to chew grass and leaves.

 

4

how many legs and wings does the grasshopper have

6 legs and 4 wings

5

Explain why the hind legs are adapted (4)

Hind legs are bigger than the rest - modified for jumping.

Hind legs have spikes, rubbed against wings makes sounds for communicating 

6

 2 things that are found in the abdomen?

* reproductive organ 

* breathing holes

7

How do grasshoppers move around (3)

By jumping flying walking

8

Explain how grasshoppers jump

The strong hind legs are used to push the grasshopper of the ground and in doing so they can jump great distances

9

explain how grasshoppers fly

The grasshopper uses the softer back par of wings to fly

10

explain how grasshoppers walk

The shorter front legs are used for walking

11

explain how grasshoppers balance

the front pair of wings is harder than the hind pair. It folds over the hind pair for protection they fold open during flight and help balance the insect

12

explain feeding and nutrition of a grasshopper

the grasshopper diet consists mostly of leaves but also eats flowers seeds stems. some species also prey on dead insects

13

explain gaseous exchange of a grasshopper

the respiratory system of insects is called the tracheal system. the grasshopper abdomen is devided into segments and each of these segments have 2 openings that are used for respiration. these openings are connected to a network of tubes called trachea which leads to all the cells. when the muscles in the abdomen relax, oxygen is taken in through these opening as the muscle in abdomen contract, carbon dioxide is forced out of the openings

14

maintaining water balance

the grasshopper is adapted to survive in dry habitats as their hard exoskeleton prevents too much moisture from escaping they dont need much water grasshoppers do not need to drink water because they get suffcient moisture from the plants they consume

15

explain reproduction

all grasshopper hatch from eggs that the female deposits in the soil from her ovipositors at the end of her abdomen the juvenile grasshopper that hatches looks very similar to the adult the grasshopper will shed 5 to 6 times during its lifespan and with each shedding small changes will occur the wings for example only develop later we call this an incomplete metamorphosis

16

explain senses

antennae used to study environment rely heavily their sense of touch sense of touch and smell used for mating hear by using an organ found front segments of abdomen this organ is sensitive to vibrations/sound waves used for communication

17

explain grasshopper in the ecosystem

* As herbivores : excrement is rich nutrients back to soil as fertiliser * Grasshoppers source food for birds and reptile * certain eat weeds that are harmful to sheep/cattle too many grasshoppers comercial farmers crops get less and plant life gets damage

18

true of false some species are brightly coloured

True

19

what does the colours of mean

warns predetors that they are poisonous

20

where is the poision

in their bodies
