Types of Animals

• Mammals. Mammals are vertebrates within the class Mammalia which have a neocortex (i.e., higher brain functions), hair, three middle ear bones, and mammary glands.
• Birds.
• Reptiles.
• Amphibians.
• Fishes.
• Insects.
• Crustaceans.
• Arachnids.

Scientists have recently estimated that there are approximately 8.7 million species on Earth. They believe that 1-2 million of those species are animals. And what do we know about all those species? Not much!

Animals can be broadly divided into two groups: invertebrates and vertebrates.

The six basic animal groups include amphibians, birds, fish, invertebrates, mammals, and reptiles. Although there are many other groups of animals, and the way scientists classify and categorize species changes frequently, in this article I’ll keep it simple by focusing on just six basic groups.

There are seven major levels of classification: Kingdom, Phylum, Class, Order, Family, Genus, and Species.

There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species.

The layers of different groups are known as taxonomic ranks. There are 8 main taxonomic ranks, from domain down to species. They are: domain, kingdom, phylum, class, order, family, genus, and species.

class Mammalia

• class Mammalia.
• fetal development group placental (Eutheria)
• order Primates.
• family Hominidae.
• genus Homo.
• species Homo sapiens sapiens Linnaeus.

The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds. Show examples of these groups and explain the characteristics that make one different from another.

Animals can be divided into five distinct groups: mammals, fish, birds, reptiles, and amphibians.

In the following slides, we’ll explore the basic characteristics shared by all (or at least most) animals, from snails and zebras to mongooses and sea anemones: multicellularity, eukaryotic cell structure, specialized tissues, sexual reproduction, a blastula stage of development, motility, heterotrophy and possession …

All animals are eukaryotic, multicellular organisms, and most animals have complex tissue structure with differentiated and specialized tissue. Animals are heterotrophs; they must consume living or dead organisms since they cannot synthesize their own food and can be carnivores, herbivores, omnivores, or parasites.

Animals are multicellular eukaryotes that lack cell walls. All animals are heterotrophs. Animals have sensory organs, the ability to move, and internal digestion. They also have sexual reproduction.

All animals are eukaryotic, multicellular organisms, and almost all animals have specialized tissues. Most animals are motile, at least during certain life stages. Animals require a source of food to grow and develop. All animals are heterotrophic, ingesting living or dead organic matter.

These are the seven characteristics of living organisms.

• 1 Nutrition. Living things take in materials from their surroundings that they use for growth or to provide energy.
• 2 Respiration.
• 3 Movement.
• 4 Excretion.
• 5 Growth.
• 6 Reproduction.
• 7 Sensitivity.

Animals can be identified by their four basic characteristics. These characteristics are movement, sounds, distinctive markings and of course their group behavior.

Multicellularity is considered as an important characteristic of the animals.

• Multucellular organisms have more than one cell inside their bodies.
• All animals are also eukaryotic.
• Eukaryotes are organisms whose cells have a nucleus enclosed within membranes.

Here is four characteristics plants have….Answer:

• Plants produce their own food.
• Plant cells have a cell wall.
• Plants reproduce with spores and sex cells.
• Plants have a vascular system.

These plants have five characteristics in common.

• Leaves. Seed plants all possess leaves in some pattern and configuration.
• Stems.
• Roots.
• Seed-Producing Capability.
• Vascular System.

Summary

• Plants are multicellular eukaryotes. They have organelles called chloroplasts and cell walls made of cellulose.
• Plants also have specialized reproductive organs.
• Almost all plants make food by photosynthesis.
• Life as we know it would not be possible without plants.

Key characteristics Plants store their food as starch. Most plants are rooted to one place – some plants can orientate leaves towards the sun and some respond to touch. Plant cell walls are rigid as they’re made of cellulose. The life cycle of plants includes both a sporophyte and a gametophyte generation.

The essential characteristics of plants

• Plants are photosynthetic.
• Plants are multicellular, primarily terrestrial organisms descended from green algae.
• Plant growth is indeterminate and adapted to gather diffuse resources.
• Shoots consist of simple repeated units exhibiting serial homology.

Plants and animals share many characteristics, but they are different in some respects. Animals usually move around and find their own food, while plants are usually immobile and create their food via photosynthesis. Plants and animals both have cells that contain DNA, yet the structure of their cells differs.

Both animal and plant cells are eukaryotic cells and have several similarities. The similarities include common organelles like cell membrane, cell nucleus, mitochondria, endoplasmic reticulum, ribosomes and golgi apparatus.

Animals can move from one place to another freely, and exceptions are Sponges and Corals. Plants have chlorophyll, due to which they have the capability to prepare their own food and are known as autotrophs. Animals are the heterotrophs, as they depend on plants for their food, either directly or indirectly.

Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.

A plant cell is surrounded by rigid cell wall whereas animal cell does not have cell wall. Presence of a large vacuole in plant cell, which is small in animal cell. Plant cells have plastids whereas animal cells do not have plastids. Centrosomes are absent in plant cell whereas animal cell have centrosomes.

The animal and plant sciences differ greatly, but they do share some commonalities. While plant sciences focus on topics such as how to make plants grow and protect them from insects, animal sciences focus on animals such as livestock, as well as managing their bodies and systems.
