GENERAL BIOLOGY 2 Quarter 3 Good day!  REMINDERS!! ALWAYS wear your face masks. FREQUENTLY sanitize your hands and/or use alcohol. AVOID unnecessary chatting with seatmates. KEEP mobile phones/gadgets temporarily.  CLASS PRAYER Father God, Come be with us today. Fill our hearts with joy. Fill our minds with learning. Fill our lesson with fun. Fill our classmates with kindness. Fill our classroom with peace. Fill our school with love. Amen. Who’s IN? Who’s OUT?  REVIEW Q. What are the divisions of geologic time scale? FQ. How does major events and life forms exist through time?  LESSON OBJECTIVES a. Identify the major groups of organisms of the geologic time scale; and b. Explain the evolution and diversity of life on our planet through the major groups of organisms.  MELC: Describe general features of the history of life on Earth, including generally accepted dates and sequence of the geologic time scale and characteristics of major groups of organisms present during these time periods. STEM_BIO11/12-IIIc-g-8  ACTIVITY 1 Group Reveal Direction: Learners analyze the given pictures and try to identify what groups of organisms are these. P K R O T S P T S T P A T S I V E E R T E V E T E R T E  ACTIVITY 2 Fact or Bluff! Direction: Learners read and analyze the statements and identify whether these are fact or bluff.  Statement 1: One important aspect of the geologic time scale is the classification of major groups of organisms that have existed throughout Earth's history.  Statement 2: Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles.  Statement 3: Protists are a diverse group of prokaryotic microorganisms that do not fit into any other kingdom.  Statement 4: Plants play a crucial role in ecosystems by providing food, carbon dioxide, and habitat for other organisms.  Statement 5: Invertebrates had a hard exoskeleton and are considered important index fossils for dating rocks.  Statement 6: Vertebrates include fish, amphibians, reptiles, birds, and mammals.  Lesson 5: The Geologic Time Scale: Major Groups of Organisms  The Geologic Time Scale: Major Groups of Organisms The Geologic Time Scale is a system used by scientists to divide Earth's history into different time periods based on major geological and biological events. One important aspect of the geologic time scale is the classification of major groups of organisms that have existed throughout Earth's history.  The Geologic Time Scale: Major Groups of Organisms These groups provide a framework for understanding the evolution and diversity of life on our planet.  Major Groups of Organisms 1. Prokaryotes - Prokaryotes are the earliest known forms of life on Earth. - They are single-celled organisms that lack a nucleus and other membrane- bound organelles.  Major Groups of Organisms - Prokaryotes include bacteria and archaea. - They appeared around 3.5 billion years ago (early Precambrian Era) and have played a crucial role in shaping Earth's environment. Major Groups of Organisms - Example: Cyanobacteria - also known as blue- green algae, were one of the first prokaryotes to perform photosynthesis, releasing… Major Groups of Organisms …oxygen into the atmosphere and contributing to the development of an oxygen-rich environment.  Major Groups of Organisms 2. Protist - Protists are a diverse group of eukaryotic microorganisms that do not fit into any other kingdom. - They can be single-celled or multicellular and have a variety of different structures and functions.  Major Groups of Organisms - Protists appeared around 2 billion years ago and played a significant role in the evolution of more complex organisms. Major Groups of Organisms - Example: Diatoms - are a type of protist that have a unique cell wall made of silica. - They are important primary producers in aquatic… Major Groups of Organisms …ecosystems and are responsible for a large portion of the Earth's oxygen production.  Major Groups of Organisms 3. Plants - Plants are multicellular eukaryotic organisms that have the ability to photosynthesize. - They appeared around 500 million years ago and have evolved into a wide variety of forms, from small mosses to towering trees.  Major Groups of Organisms - Plants play a crucial role in ecosystems by providing food, oxygen, and habitat for other organisms. Major Groups of Organisms - Example: Ferns - are a group of plants that reproduce via spores and have vascular tissues for transporting water and nutrients. Major Groups of Organisms - They were dominant during the Carboniferous period and formed extensive coal deposits.  Major Groups of Organisms 4. Invertebrates - Invertebrates are animals that do not have a backbone. - They make up the majority of animal species on Earth and have a wide range of forms and adaptations.  Major Groups of Organisms - Invertebrates appeared around 600 million years ago and have diversified into numerous phyla, including arthropods, mollusks, and echinoderms. Major Groups of Organisms - Example: Trilobites - were a group of extinct marine arthropods that lived from the Cambrian to the Permian period. Major Groups of Organisms - They had a hard exoskeleton and are considered important index fossils for dating rocks.  Major Groups of Organisms 5. Vertebrates - Vertebrates are animals that have a backbone or spinal column. - They include fish, amphibians, reptiles, birds, and mammals. - Vertebrates appeared around 500 million years ago and have undergone significant evolutionary changes over time. Major Groups of Organisms - Example: Dinosaurs - were a diverse group of reptiles that dominated the terrestrial ecosystems during the Mesozoic era. Major Groups of Organisms - They ranged from small, bird-like creatures to massive, long-necked herbivores and fearsome carnivores. Questions?  ACTIVITY 3 Matching Characteristics Direction: Learners match the key terms in the Column A to those in Column B.  COLUMN A COLUMN B ___1. Single-celled, lack a nucleus and other A. Prokaryotes membrane-bound organelles ___2. Multicellular eukaryotic organisms, B. Protist have the ability to photosynthesize ___3.

Vertebrates  Application Q. To which activity /scenario in your daily life can you relate the concepts discussed?  Let’s Wrap Up! Sum up the lesson through answering the following questions based on the topic: a. What are the major groups of organisms in the geologic time scale? b. How are these organisms classified in groups?  ENRICHMENT Direction: Do advance study and research regarding: Mechanisms of Evolution THANK YOU!
