Políferos e etnidários 00:00:00
As características dos políferos 00:00:03
Son os máis acuáticos 00:00:05
Se deixan atascados a un substrato 00:00:07
E ten unha simetría radial 00:00:09
A parte dos seus corpos 00:00:12
Ten pequenos buracos 00:00:14
Que se chaman poros 00:00:15
Que a agua flota 00:00:16
Tambén ten un gran buraco 00:00:17
Que se chaman osclum 00:00:20
En que a agua é expelida 00:00:21
A parte de dentro 00:00:24
Ten pequenos células 00:00:25
Que se chaman xanocite 00:00:27
e unha cavidade interna chamada atrium. 00:00:28
Son filtros filtrados, 00:00:32
que filtra unha pequena organismo no agua. 00:00:35
Poden ser de moitas colores 00:00:38
e, nos antigos tempos, 00:00:40
o esqueleto foi usado para a personalidade. 00:00:42
As esponjas ten unha body 00:00:46
suportada por estruturas de nido chamadas espiculas. 00:00:48
As tres funciones de vitamina 00:00:52
en periferia, 00:00:55
a nutrición, 00:00:56
They have no digestive system 00:00:57
and they filter water 00:01:01
to trap small organisms 00:01:03
that water enters 00:01:05
through the pores 00:01:07
and the particles 00:01:08
are trapped 00:01:11
inside the atrium. 00:01:15
Reproduction. 00:01:17
They can reproduce asexual 00:01:18
and asexual. 00:01:20
Asexual. 00:01:21
They reproduce asexual 00:01:22
by biting. 00:01:25
é similar a 00:01:26
a transmisión, pero 00:01:28
con unha pequena parte 00:01:29
de beboide 00:01:31
sexual, derrota da ducha 00:01:33
sexual by gamete 00:01:35
o male gamete 00:01:37
se unha con a femenina 00:01:39
e produza fertilización 00:01:41
e crea unha nova 00:01:43
interacción 00:01:44
non ten individual 00:01:46
células ou organismos 00:01:48
que son especiales 00:01:51
to detect environmental 00:01:54
streams, 00:01:56
like 00:01:59
serms, 00:01:59
mothman, 00:02:01
darnex. 00:02:02
However, they saw a number 00:02:04
of small 00:02:07
biobots 00:02:08
that were 00:02:10
responsible. 00:02:11
The characteristics of medallions. 00:02:14
They have radial symmetry 00:02:17
and the most leafy in seas, 00:02:18
oceans. 00:02:21
They have a bug-shaped body 00:02:21
They have a gastrovascular cavity 00:02:24
That acts as a stomach 00:02:27
Connected to the outside by holes 00:02:29
Equally, they have tentacles 00:02:31
A mouth that acts as both 00:02:34
As anus 00:02:36
They have felt 00:02:37
Calles nidocites 00:02:39
They use the tentacles 00:02:41
To capture small platonic animals 00:02:46
That they eat 00:02:49
Two different forms 00:02:50
Onidarians 00:02:51
Polyps and jellyfish 00:02:52
Polyps 00:02:55
Live attached to a substrate 00:02:56
Their back shape 00:02:59
And their mouth is at the top 00:03:01
Jellyfish 00:03:03
Float around the sea 00:03:04
Their bodies are like an umbrella 00:03:06
And their mouth 00:03:09
Is under the gastrovascular cavity 00:03:11
The three vital functions 00:03:13
Of Onidarians 00:03:17
Nutrition 00:03:19
O sistema digestivo do desnidario é moi complexo, mas tamén simples. 00:03:20
Tén un sistema digestivo de un modo, 00:03:27
un modo que significa que toda a comida, digestiva ou non, 00:03:29
se passa do mesmo modo. 00:03:37
Este proceso se chama cavidade gastrovascular. 00:03:40
Usan células nos tentáculos para capturar a comida. 00:03:44
Reproducción. 00:03:48
They can reproduce asexually and sexually, the same as poriferous. 00:03:49
Asexual. 00:03:55
They reproduce asexually via body. 00:03:56
It's similar to fragmentation, but with a smaller part of the body. 00:03:59
Sexual. 00:04:06
They reproduce asexually via gametes. 00:04:07
The male gametes join with the female and produce fertilization and create a new one. 00:04:11
Interacción 00:04:18
Etnidáneos 00:04:19
have a rudimentary 00:04:21
nervous system 00:04:24
Neurons are located regularly 00:04:25
over the surface of the animal 00:04:27
and like an egg 00:04:30
they are in contact with 00:04:32
dust nearest to it 00:04:33
The effect of 00:04:36
such an arrangement 00:04:37
is then a 00:04:40
stimulus 00:04:41
Applied to any part of the animal 00:04:42
will be directed 00:04:46
a todos os planos. 00:04:47
