Answer:
Explanation:Give their phylum too. 2. Give the classification of the plant kingdom. 3. Differentiate between vertebrates and invertebrates 4. Give the difference between two types of symmetry that animals show. 5. ... [3] Vertebrates have backbone or spinal cord while invertebrates have no backbone and no cell wall.
1.
Flat worms
Phylum - Platyhelminthes
Dorsoventrally flat, i.e. flat body from top to bottom.0 100um.
No true body cavity.
Mostly hemaphrodite, i.e., male and female sex organs present in the same individual.
Round worms
Phylum - Nematoda
Body is cylindrical.
Pseudocoelom (Sort of body cavity).
Sexes are separate.
Segmented worms
Phylum - Annelida
Body is segmented from head to tail.
True body cavity.
May be unisexual or bisexual.

Based on whether plants have a well-differentiated body and the presence or absence of specialized tissues for transport, and the ability to bear seeds Kingdom Plantae (Plant Kingdom) is can be classified into different divisions. The features and examples of each division are mentioned hereunder.
3.
The animal kingdom has been divided into two major groups: Invertebrates (Non-Chordates) and Vertebrates (Chordates). Invertebrates are those that do not possess a vertebral column or backbone while Vertebrates are those where vertebral column or backbone is present.

The difference between bilateral symmetry and radial symmetry are as follows:
(i) Bilateral symmetry: Organism having same design on left and right halves of the body are called as bilateral symmetrical. Examples: earthworm, spider, cockroach
(ii) Radial symmetry: Organisms with a body design such that it can be divided into two equal halves from any diameter are known as radially symmetrical. Examples: starfish, sea-urchins.

The flowering plants or the angiosperms are the most diversified group of plants. Most of the plants that you see around and that which dominate the plant population belong to this group. The angiosperms are further divided into monocotyledon and dicotyledon. These two differ in four different structural traits: roots, stems, leaves and flower. But, variations begin from the seed: the start of a plant’s life cycle. Cotyledon refers to the ‘first seed leaf’, present in the embryo. If it is a single seed leaf, then it is categorised as monocots and if it is a pair of leaves then it is categorised as dicots.

A) Coelom is not common for the above classes in the animal kingdom because Platyhelminthes shows acoelomic nature, while others show true coelom.
B) symmetry is also not common because Platyhelminthes are bilaterally symmetrical same as mammals amphibians whereas Echinodermata is symmetrical in many planes and coelentrata is radially symmetrical
c) appendages are different in different organisms of these classes, some have tube feet, some have cilia others have limbs etc.
