Question

Differentiate the following
1) Phanerogams and Cryptogams
2) Diploblastic and Triploblastic Animals
3) Pseudocoelome and True coelom
4) Radial and bilateral symmetry

Answer 1

Hint: The diverse world around us, with millions of biotic and abiotic components that make up our ecosystem.
> Animals are eukaryotic life arrangements, considered by heterotrophic mode of food and inhabit all types of ecologies including terrestrial, freshwater and marine. They can be more segregated into two groups based on the occurrence of notochord.
> Plantae is the plant kingdom which comprises all plant life in the world. They are multicellular eukaryotes. Typically, they comprise an inflexible structure that ambiances the cell crust known as the cell wall.

Complete answer:
1. Difference between Phanerogams and Cryptogams

Phanerogams	Cryptogams
Phanerogams are relatively more evolved.	Cryptogams are relatively less evolved.
These plants have reproductive tissues that are well-differentiated.	They contain hidden reproductive organs.
For reproduction, these plants produce seeds.	For reproduction, they produce spores.
Angiosperms and gymnosperms are phanerogams.	The divisions that fall under this include Thallophyta, and Bryophyta.
Require external water for fertilization.	Do not require external water for fertilization.
Examples: Conifers, mango and banyan dicot	Examples: Algae, silkworms and ferns

2. Difference between Diploblastic and Triploblastic Animals

Diploblastic Animals	Triploblastic Animals
The cells are organized in two embryonic layers-exterior ectoderm and interior endoderm.	The cells are organized in two embryonic layers- external ectoderm, intermediate layer of mesoderm and centre endoderm.
Body wall consists of two major tissue layers.	Body wall consists of three major tissue layers.
Mesoglea is extant between the ectoderm and the endoderm.	Mesoglea is absent. In its place, the mesoderm is existing between the endoderm and the ectoderm.
Coelom is absent	Coelom is present
Examples: Cnidaria and Ctenophora.	Examples: Platyhelminthes to Chordata.

3. Difference between Pseudocoelome and true coelom

Pseudocoelome	True coelom
Fluid filled extracellular body fissures of certain triploblastic animals live in between the body wall and the intestine.	Fluid filled perivisceral fissure of most triploblastic animals (e.g., best annelids and vertebrates), located between the body wall and gut. In arthropods and molluscs, it is not the perivisceral hole; it creates the fissure of excretory organs and gonads .
A false body cavity is the scrap of the embryonic blastocoel.	True body cavity matures from the splitting of embryonic mesoderm or coelomic cavity formed from the out- pocketing of the embryonic archenteron.
It has no family member of the excretory and generative tissues.	It has a relative of the excretory and generative tissues.

4. Difference between Radial and bilateral symmetry

Radial symmetry	Bilateral symmetry
Radial symmetry makes the same body split round the dominant axis..	Bilateral symmetry generates only two sides as left and right along the sagittal plane..
Body cannot be distributed into left and right margins.	The Sagittal plane splits the body into left and the right margins.
Similar body fragments are organized in a regular manner around the essential axis.	Similar body fragments are organized in both left and right sides similarly.

Note:
• Phanerogams are plants that contain seeds and Cryptogams are plants that do not contain seeds.
• Diploblastic animals are made up of only two germ layers known as the endoderm and the exoderm whereas triploblastic are made up of three germ layers that are endoderm, exoderm, and mesoderm.
• Pseudocoelome have false body cavities and true coeloms have true body cavities.
• Also coelom acts as a shock absorber- It protects from mechanical shock. They also support the immune system and help in gases transportation etc.
• Radial symmetry have multiple planes of symmetry where bilateral symmetry have only one plane of symmetry passing through their bodies.
