Invertebrates class ppt
Scientists classify animals into groups based on similarities to make the large number of species more organized. Vertebrates have backbones while invertebrates do not, and major invertebrate groups include jellyfish, flatworms, roundworms, segmented worms, mollusks, starfish, sea urchins, and arthropods such as crustaceans, insects, spiders, and centipedes/millipedes. Arthropods can be further divided based on traits like number of body segments, legs, and wings.
biology-levels of organization
This document provides an overview of biological organization from the biosphere level down to the subatomic particle level. It outlines the key levels of organization such as ecosystems, organisms, tissues, cells, organelles, molecules and atoms. The objective is to understand the different hierarchical levels of biological structure and organization, from the largest to the smallest level. It also defines some key terms used to describe biological organization like biosphere, population, species, organ and tissue.
Classification of Living Things
This document provides an overview of taxonomy and the classification of living organisms. It explains that taxonomy is the scientific study of naming and grouping organisms based on similarities. A standard 7-level classification system was developed by Carolus Linnaeus, with domains, kingdoms, phyla, classes, orders, families, genera and species. Organisms are grouped into six kingdoms - Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia - based on their cell structure, number of cells, and method of feeding. The document describes the defining characteristics of each kingdom.
The organization of living things
Multicellular organisms have several advantages over unicellular organisms including larger size allowing them to avoid more predators, longer lifespans not limited by single cells, and specialization where each cell type performs a specific job making the organism more efficient. The structure of organisms is organized into hierarchical levels from cells to tissues to organs to organ systems with each level working together to carry out life processes. Structure and function are also related in organisms, where the arrangement of parts enables them to perform their necessary jobs.
Vertebrates
This document divides animals into two main groups: vertebrates and invertebrates. Vertebrates have backbones and include fish, mammals, and birds, while invertebrates like spiders and flies do not have backbones. It then provides more details about characteristics of different types of vertebrates, including that warm-blooded vertebrates regulate their own body temperature while cold-blooded vertebrates depend on the environment, and lists examples of classes of vertebrates such as fish, amphibians, reptiles, birds, and mammals.
Organization levels of living organism
Organisms are organized into different levels from molecules to biomes. The basic unit of life is the cell, which is composed of molecules like carbohydrates, lipids, proteins and nucleic acids. Cells make up tissues like muscle and nervous tissue. Tissues combine to form organs such as the heart and brain. Multiple organs that work together comprise organ systems like the digestive or respiratory systems. An individual organism is made up of various organ systems. Populations of organisms living in the same area form a community. A community and its physical environment together create an ecosystem. The largest organization level is a biome, which describes large communities on Earth.
Unicellular and mulitcellular
This document discusses unicellular and multicellular organisms. Unicellular organisms are made of only one cell and include bacteria, amoebas, and unicellular fungi and yeasts. They are microscopic and need to be seen with a microscope. Multicellular organisms are made of two or more cells and include humans, cats, dogs, insects, trees and more. They can be seen with the naked eye and need all parts to survive. Examples are given of both unicellular and multicellular organisms.
Classification system
The document discusses the classification of living things. It explains that Carolus Linnaeus developed the system of binomial nomenclature over 200 years ago to scientifically name organisms. Each organism is given a two-word Latin name with the genus as the first word and the species as the second word, following specific rules. There are 7 levels of classification for organisms from broadest (kingdom) to most specific (species). The document provides examples and explanations of scientific naming and the levels of biological classification.

Chapter 4 - Cells
Robert Hooke first observed cells in 1665 using a microscope to look at cork. Anton van Leeuwenhoek later observed the first living cells in pond water in 1673. In the 1800s, scientists including Matthias Schleiden, Theodor Schwann, and Rudolph Virchow developed the cell theory, which states that all living things are composed of cells, cells are the basic units of structure and function, and cells only come from preexisting cells. Cells later evolved to be more specialized and form multicellular organisms through the development of tissues, organs, and organ systems.
Animal Kingdom
This document provides an overview of the animal kingdom, describing their key characteristics and how they are classified. It discusses that animals are divided into invertebrates and vertebrates. Invertebrates make up 98% of animal species and lack backbones, while vertebrates make up the remaining 2% and include fish, amphibians, reptiles, birds and mammals which all have backbones. It then examines several animal phyla in more detail, describing their defining features, organs and organ systems.
Levels of organization
This document describes the different levels of biological organization in multicellular organisms from cells to biosphere. It discusses five levels - cells, tissues, organs, organ systems, and organisms. Cells are the basic unit and make up tissues. Tissues combine to form organs, organs work together in organ systems, and organ systems function as a whole organism. Higher levels depend on and are affected by the levels below them.

Animals classification
This document classifies animals according to their structure, diet, and reproduction. It divides animals into invertebrates without backbones and vertebrates with backbones. Invertebrates include arthropods, worms, mollusks, sponges, and echinoderms. Vertebrates include mammals, birds, fish, reptiles, and amphibians. Mammals are viviparous and nourish their young with milk. Birds lay eggs but are otherwise diverse. Fish primarily reproduce through laying eggs while reptiles can be either viviparous or oviparous. Amphibians undergo metamorphosis from aquatic young to terrestrial adults.
Decay And Decomposition
Decomposers like mushrooms, worms and bugs play an important role in decay and decomposition by breaking down dead organisms and converting them into soil. For decay to occur, certain conditions need to be present including warmth, moisture and oxygen. Without decomposers, dead organisms would accumulate and the world would be covered in remains rather than recycled into dirt.
Classification of animals
This document provides an overview of how living things are classified. It explains that living things are divided into two large groups: animals and plants. Animals are further divided into vertebrates and invertebrates. Vertebrates are animals with backbones and include five groups: amphibians, birds, fish, mammals, and reptiles. Each group is described. Invertebrates do not have backbones and include eight groups: molluscs, flatworms, annelids, roundworms, sponges, echinoderms, cnidarians, and arthropods. Details are provided on the characteristics of each invertebrate group.
Levels of organization
There are 8 levels of organization in biology:
1. Cells are the basic unit of structure and function.
2. Tissues are groups of cells that perform specific functions.
3. Organs are made of different tissues working together to perform functions like the heart.
4. Organ systems are groups of organs that work together, like the circulatory system.
5. Organisms are made up of all cells, tissues, organs and organ systems.
6. Populations are groups of the same type of organisms living together.
7. Communities are groups of populations that interact in an area.
8. Ecosystems are populations living together in an area.
Zoology introduction
This document provides an overview of the textbook "Integrated Principles of Zoology, 14/e" which examines animal life through the scientific study of zoology. The textbook is authored by Cleveland P. Hickman Jr., Larry S. Roberts, Allan Larson, Helen I'Anson, and David Eisenhour and includes 14 chapters discussing topics such as life and biological principles, cells, genetics, evolution, reproduction, and development. It uses principles of physics, chemistry, and the scientific method to explore different levels of biological organization from macromolecules to populations and evolutionary trends across species.
Characteristics of living things
This document outlines the key characteristics of living things:
1) All living things are made of cells and use the same basic elements of carbon, hydrogen, nitrogen, and oxygen.
2) Living things are organized in complex hierarchies from molecules to cells to tissues and organs.
3) Common characteristics include the ability to reproduce, grow, develop and change over time, respond to their environment, maintain homeostasis, obtain and use energy, and pass genetic information between generations.
Levels of classification
This document provides information on biological classification systems. It discusses why classifying living things is important, provides a brief history of classification methods, and describes the current system of classification. The current system is based on 3 domains - Bacteria, Archaea, and Eukarya - which are further divided into kingdoms based on characteristics like cell structure, nutrition, and whether organisms are unicellular or multicellular. The 6 kingdoms are Bacteria, Archaea, Protista, Fungi, Plantae, and Animalia. Each kingdom has distinguishing features that are described.
Cell: The basic unit of life
The cell is the basic unit of life. It contains a nucleus and cytoplasm, which includes organelles like the cell membrane, mitochondria, and endoplasmic reticulum. The cell membrane regulates what enters and exits the cell, and maintains homeostasis. Inside the cell, the nucleus contains DNA and directs cell activities, while the cytoplasm and organelles work together to carry out essential functions and keep the cell alive.

Interactions within ecosystems
This document discusses interactions between living things within ecosystems. It describes the five levels of organization within ecosystems from largest to smallest as biome, ecosystem, community, population, and organism. Patterns exist in populations related to living space and time. Population sizes change over time due to factors like predator-prey relationships, birth and death rates, limiting factors, and carrying capacity. Organisms interact through predation, competition, cooperation, and symbiosis. Ecosystems also change over time through ecological succession as one community replaces another.
Cell theory & types of cells
Cell theory states that all living things are composed of cells, cells are the basic unit of structure and function, and new cells are produced from existing cells. Cells can be classified as prokaryotic, which lack organelles and a nucleus, or eukaryotic, which contain organelles and a nucleus. Eukaryotic cells can be single-celled or multi-cellular, and multi-cellular organisms contain specialized cells that perform distinct functions like transport, storage, photosynthesis, and more.
Human body systems
The document discusses the major organ systems of the human body through a series of questions about each system. It covers the circulatory, excretory, nervous, digestive, respiratory, skeletal, muscular and integumentary systems. Each question prompts the reader to identify a specific organ or overall system shown in accompanying diagrams.

The document also notes that all living things must possess all seven of these characteristics.
Classifying Animals and their Group
This document discusses and compares vertebrates and invertebrates. Vertebrates are animals with backbones, and there are five classes: fish, amphibians, reptiles, birds, and mammals. Each class is then described in 1-2 sentences. Invertebrates are animals without backbones that can take care of themselves after hatching from eggs. Insects are described as the largest group of invertebrates, having six legs and one or two pairs of wings.
Animals-class-and-char.ppt
- Animals are multicellular, heterotrophic organisms that lack cell walls and have tissues that allow movement and response to stimuli. They have complex internal structures and usually bilateral or radial symmetry.
- Organisms are classified based on their physical characteristics and internal structures, grouping those with greater similarities together into taxonomic ranks like kingdom, phylum, class, order, family, genus and species.
- The scientific name uses binomial nomenclature, specifying both the genus and species of the organism. This provides a standardized classification system.
Kingdom Animalia
The document discusses key characteristics of animals in the kingdom Animalia. It notes that animals are multicellular, mitochondrial heterotrophs that ingest and digest food internally. There are estimated to be around 9-10 million animal species on Earth across 36 phyla. Most animals exhibit bilateral symmetry and sexual reproduction, and range widely in size and habitat. Advanced animal body plans evolved from simpler multicellular to bilaterally symmetrical to coelomate forms with specialized tissues and organs.
Diversity in Living Organisms
This document provides an overview of the classification of living organisms into taxonomic groups from the cellular level to multicellular organisms. It summarizes key biologists like Whittaker who classified organisms into five kingdoms - Monera, Protista, Fungi, Plantae, and Animalia. Each kingdom is then further divided into subordinate taxa with defining characteristics described. The classifications of plants, animals and protists are summarized in a hierarchical outline.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
