Hi everyone, welcome to the unit 3 of our natural science subject, which is all about invertebrates.
00:00:04
Invertebrates.
00:00:15
Mirror word.
00:00:16
Invertebrates.
00:00:20
Invertebrates do not have backbone and skeleton.
00:00:26
Mirror word.
00:00:33
In vertebrates, do not have bone and skeleton vital functions.
00:00:35
In vertebrates, perform three vital functions.
00:00:53
Nutrition, reproduction, interaction.
00:01:01
Mirror word. Invertebrates perform three vital functions. Nutrition, reproduction, interaction.
00:01:06
Nutrition. Carnivores, spiders, and dragonflies only eat other animals.
00:01:23
Herbivores, grasshoppers, only eat plants.
00:01:39
Omnivores, ladybugs, and snails eat both animals and plants.
00:01:53
Mirror word. Carnivores. Spiders and dragonflies only eat other animals.
00:02:06
herbivores, grasshoppers only eat plants, omnivores, ladybugs and snails eat both animals and plants.
00:02:25
For example, spiders are carnivore.
00:02:53
Grasshoppers are, or ladybugs, are omnivore.
00:03:03
And then grasshoppers, what do you think?
00:03:09
Herbivore.
00:03:12
How about snails?
00:03:13
What do you think?
00:03:15
Omnivore.
00:03:17
How about dragonflies?
00:03:18
Carnivores.
00:03:22
Reproduction, one.
00:03:25
Most invertebrates are oviparous animals, but some are ovoviparous animals.
00:03:27
The eggs grow inside their bodies.
00:03:41
They hatch before or after they lay them.
00:03:45
Mirror word.
00:03:50
Most invertebrates are oviparous animals.
00:03:54
Some are ovoviparous animals.
00:04:04
Eggs grow inside their bodies.
00:04:09
They touch before or after they lay them.
00:04:15
Examples of this, animals, beetles, aphids, flies.
00:04:20
Reproduction too.
00:04:34
Sexual reproduction, a male and a female are necessary to create a new organism.
00:04:37
The offspring, or the baby, may be different from their about a sexual reproduction.
00:04:59
One organism makes an identical copy of itself.
00:05:10
The offspring, or the baby, is identical to the, mere word, sexual reproduction.
00:05:16
A male and a female are necessary to create a new organism.
00:05:31
The offspring or the baby may be different from their parents.
00:05:43
Sexual reproduction, B.
00:05:52
One organism makes an identical copy of itself.
00:05:54
The offspring is identical to the pet.
00:06:05
Asexual reproduction.
00:06:18
Let's talk more about asexual reproduction.
00:06:20
Let's start with body.
00:06:23
the body the new organism grows in the parent's body so it grows from the parent so this is the
00:06:25
parent it grows and then separates to form another body so one example is the organism
00:06:37
hydra so the parent hydra and then the bud formation it grows from the parent's body
00:06:47
and then it separates and then there's a new hydra okay so that's for body
00:06:58
how about for fragmenting it broken it breaks down the new organism grows from a part
00:07:09
of its parent.
00:07:20
So, one example is the starfish.
00:07:24
So, from starfish,
00:07:28
and then it breaks into two.
00:07:30
And then from each part,
00:07:33
it grows into two organisms.
00:07:36
Mirror word.
00:07:43
A sexual reproduction.
00:07:45
Body.
00:07:49
The new organism grows
00:07:50
then separates, fragmenting the new organism grows from a part of its parent.
00:07:53
Interaction 1.
00:08:14
All animals interact with their environment.
00:08:18
Most invertebrates live in groups or large communities
00:08:22
Hermit crabs are very social
00:08:31
They live in big groups
00:08:37
Bees live in beehives forming large communities
00:08:41
Mirror word
00:08:52
All animals interact with the environment.
00:08:56
Most invertebrates live in groups or large communities.
00:09:05
Hermit crabs are very social.
00:09:17
They live in big groups.
00:09:22
Bees live in beehives, forming large communities.
00:09:26
Interruption 2.
00:09:40
Most invertebrates have tense organs and react to stimuli.
00:09:43
I think you know the five senses, right?
00:09:50
So example, octopuses.
00:09:54
So octopuses use six arms and two legs to eat and move.
00:09:56
The orchid mantis uses camouflage to attract and hide from its prey.
00:10:07
Mirror word.
00:10:18
Most invertebrates have sense organs to react to stimuli.
00:10:20
To possess, use six arms and two legs to eat and move.
00:10:26
The crooked mantis uses camouflage to attract and hide meat spray.
00:10:39
The thumb invertebrates use sound to communicate.
00:10:49
Prickets or cicadas use sounds to warn of danger and attract opposite stings for reproduction.
00:11:00
Napping shrimps use their claws to snort noise to avoid predators.
00:11:17
Mirrorworms, some invertebrates, use sound to communicate.
00:11:25
Rickets or cicadas use sound to warn of danger or to attract opposite sex.
00:11:36
Napping shrimps use their claws to snort noise or avoid attack.
00:11:51
So that's all for our invertebrates.
00:12:04
So I hope that you keep practicing with me and I'm going to see you in the class.
00:12:08
Bye bye.
