Characteristics of Life

1. Welcome, Aristotle’s army!

2. General Biology 1 This subject is designed to enhance the understanding of the principles and concepts in the study of biology, particularly life processes at the cellular and molecular levels. It also covers the transformation of energy in organisms.

3. Quarter 1 Lesson 1: Characteristics of Life

4. Objectives: identify and describe the characteristics of an organism apply knowledge on classifying whether living and nonliving appreciate the importance of microorganisms

5. CHARACTERISTICS

6. Biologists have identified various characteristics common to all the organisms that we know about. While nonliving things may show some of these characteristics, only living things show them all.

7. Characteristics of Life

8. 1. Growth and Development Characteristics of life

9. Growth and development Have you ever wonder, how you develop from a fetus to a Disney princess?

10. Growth and development Have you ever wonder, how you grow? Imagina gikan sa paggawas nio sa imong mama hangtod karon .

11. Growth and development All organisms have the ability to grow and develop . These organisms utilize nourishment from their environment together with instructions coded by their genes. Examples of growth and development in multicellular organisms include cell growth and cell division.

12. Growth and development Plants germinate, sprout, root, leaf out and bloom mainly through the cellular level process of mitosis. Plant growth is the process through which the plant increases in size. A mature plant has healthy leaves and strong stem. The light energy is used during photosynthesis while the growth process is enhanced by the uptake of nutrients.

13. How they do differ? Growth Development

14. -increase in size Growth Growth Growth

15. -changes development

16. How they do differ? Growth Development -increase in size -changes

17. 2. Maintain homeostasis Characteristics of life

18. Maintain homeostasis In order for higher forms of organisms to function properly, they must maintain appropriate concentrations of different chemicals, pH level, optimum temperature, etc., because these conditions may change from time to time depending on changes in their environment. Organisms must maintain a steady state of internal condition despite these varying conditions.

19. - stable, balance homeostasis - Necessary for survival

20. Can you identify some examples of homeostasis?

21. 3. reproduction Characteristics of life

22. reproduction Organisms have the ability to reproduce or generate more organisms of their own kind. Reproduction is the process of succeeding generations thru sexual or asexual processes, which involves passing down of genes from parents to their offspring.

23. reproduction

24. reproduction

25. - A group of organisms consisting of similar individuals capable of exchanging genes or interbreeding species

26. Sexual and asexual reproduction

27. 4. Response to Environment or Stimuli Characteristics of life

28. Response to environment or stimuli Organisms have the ability to respond to different environments and diverse stimuli. Adaptation is a process of an organism adjusting to better match its environment .

29. Response to environment or stimuli Plss give me an example of this characteristic…

30. Response to environment or stimuli A dog salivating at smell of food

31. Response to environment or stimuli A flower opening in sunlight

32. Response to environment or stimuli A worm crawling towards moisture

33. Response to environment or stimuli Kanang makulbaan ka kung makit -an xa !

34. 5. Energy processing Characteristics of life

35. Energy processing All organisms require energy for their cellular metabolic activities to occur.

36. Energy processing Kapila ka mokaon sa isa ka adlaw ?

37. Energy processing Photosynthetic processes are of two types: Oxygenic photosynthesis is the most common and is seen in algae, cynobacteria and plants. Light energy transfers electrons from water (H2O) to carbon dioxide (CO2) in order to produce carbohydrates. The CO2 is “reduced” or receives electrons in this transfer and the water becomes “oxidized” or loses electrons. Anoxygenic photosynthesis, on the other hand, makes use of electron donors other than water. The anoxygenic photosynthesis contains no by-product of oxygen.

38. 6. Organized Characteristics of life

39. organized Organisms form highly organized and coordinated structures in order to function properly. In multicellular organisms, similar cells forms tissues, tissues of the same function form an organ, a group of organs with distinct functions form organ systems and an organ system which compliments each other to support life forms an individual.

40. organized The smallest functional unit of all living things are the cells .

41. EXAMPLES OF HUMAN CELLS BLOOD CELLS

42. EXAMPLES OF HUMAN CELLS EGG AND SPERM CELLS

43. Group ACTIVITY: Explore the school surroundings to observe different living organisms. Take a picture of them and Take note on the characteristics you observe in each organism. Classify organisms based on their shared characteristics. explain the significance of these characteristics in the survival of organisms. Report it to the class.
