3. List & explain the various features involved in KINGDOM ANIMALIA.


GENERAL INSTRUCTIONS :-


1. Write your notes in your register.
2. There is only one YouTube video link sent with this blog . Kindly watch it first before reading the blog.

3. Draw diagram of LIFE CYCLE OF PLANTAE in your register.

4. Read NCERT  on the topics covered today .
5. ASK YOUR DOUBTS.
6. PREPARE FOR THE QUIZ TEST FROM WHOLE CHAPTER 2 ON 15TH MAY 2020.


LET'S BEGIN


KINGDOM PLANTAE GENERAL CHARACTERISTICS 

Kingdom Plantae

1. Eukaryotic, chlorophyll bearing organism.
2. Life cycle is divided into diploid Sporophytic and haploid Gametophytic phases , which alternate with each other.
3. Kingdom Plantae includes Algae, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.

LIFE CYCLE OF KINGDOM PLANTAE

Life cycle of plants has two distinct phases – the diploid sporophytic and the haploid gametophytic – that alternate with each other. The lengths of the haploid and diploid phases, and whether these phases are free– living or dependent on others, vary among different groups in plants. This phenomenon is called alternation of generation. You will study further details of this kingdom in Chapter 3. 

KINGDOM ANIMALIA GENERAL CHARACTERS

This kingdom is characterised by heterotrophic eukaryotic organisms that are multicellular and their cells lack cell walls.

- They directly or indirectly depend on plants for food. They digest their food in an internal cavity and store food reserves as glycogen or fat.

- Their mode of nutrition is holozoic - by ingestion of food.

- They follow a definite growth pattern and grow into adults that have a definite shape and size.

- Higher forms show elaborate sensory and neuromotor mechanism.

- The sexual reproduction is by copulation of male and female followed by embryological development.

·        Anaima: Animals without red blood e.g., sponges, cnidaria, mollusca, arthropoda, echinodermata, etc.

·        Enaima: Animals with red blood e.g., vertebrate

·        Vivipara: Animals which give birth to young ones are included in this subgroup e.g., man, dogs, cows, etc.

·        Ovipara: Animals which lay eggs are included in this subgroup e.g., frogs, toads, lizards, snakes, birds, etc.

·        Anamniotes: Vertebrates without embryonic membranes e.g., fishes, amphibians.

·        Amniotes: Vertebrates with embryonic membranes (chorion, amnion, allantois, yolk sac) e.g., reptiles, birds, mammals.

·        Acraniata or Protochordata: Chordates without cranium (brain box). It includes urochordata and cephalochordata.

·        Chordates: Animals with notochord dorsal tubular nerve cord, paired pharyngeal gill slits.

·        All urochordates, cephalochordates and vertebrates are called chordates.

·        Craniata or Vertebrate: Chordates with cranium.

·        It Includes cyclostomes, pisces, amphibians, reptiles, birds and mammals.

·        Nonchordates: Animals without notochord (a rod like elastic structure which supports the body). Phylum Porifera to phylum Hemichordata are called nonchordates.

·        Invertebrates: Animals without vertebral coloumn (backbone). All the nonchordates, urochordates and cephalochordates are collectively called invertebrates.

HOME WORK TASK :-

ANSWER THE FOLLOWING QUESTIONS  :

1. Explain what is Alternation of generations . Which KINGDOM displays this property.

2. Differentiate between Anaima & Enaima .

3. Justify the position of INSECTIVOROUS plants in KINGDOM PLANTAE.

That's all for today's class .

I will meet you tomorrow according to DAY 3 time table.

Till then ask your doubts .
