Tissues Are groups of cells which have similar functions, structures and purposes Form many structures within the body, including muscles and organs 15. Muscular System Is composed of specialized cells with unique features called muscle fibers Is controlled by the nervous system 16. Muscular System Supports movement and assists in other body functions example: for the human knee to straighten, one group of muscles at the front of the thigh must contract and muscles behind the knee must relax Accompanies: Plants & Animals: What s the Difference? 11

12 17. Muscle Types skeletal muscle responsible for skeletal movements, voluntarily controlled by organisms smooth muscle found within hollow organs such as the bladder, uterus and blood vessels; involuntarily controlled by the nervous system cardiac muscle found within the heart, involuntarily controlled by the nervous system 18. Muscle Types Accompanies: Plants & Animals: What s the Difference? 12

13 19. Organs Structures composed of specialized tissues designed to serve a specific function for the body Often belong to larger body systems to serve a particular purpose for the organism Fun Fact: Tissues are groups of cells which have similar functions, structures and purposes. They form many structures within the body, including muscles and organs. 20. Organ Types skin usually the largest organ and acts as a defense against disease and physical harm lungs are a pair of organs responsible for respiration heart an organ responsible for pumping blood throughout the body 21. Organ Types For digestion include: esophagus tube which utilizes rhythmic constriction and relaxation to bring food to the stomach stomach organ which churns food and mixes it with digestive enzymes for further processing intestines organs utilized for chemical digestion and removal of waste 22. Body Systems Are specialized groups of organs and other body parts designed to carry out specific tasks for the organism Are not universally identical from animal-to-animal Will not be used the same way by all animals Accompanies: Plants & Animals: What s the Difference? 13

14 23. Body Systems nervous system of organs utilizing nerve impulses to control various parts of the body including muscles and other organs digestive system of organs, including the stomach, esophagus and intestines, which process food for energy absorption and eliminate waste 24. Body Systems circulatory system of organs, including arteries and veins, responsible for transporting materials throughout the body excretion system of organs, including the anus and colon, responsible for processing and removing waste from the body 25. Body Systems respiratory system of organs, including the larynx, trachea and lungs; conducting air for blood cells and exchanging gas reproductive system of organs, including the testes in males and ovaries in females; are responsible for the creation of sperm and eggs utilized for reproduction and development of offspring Life Cycle Comparison Segment 1. Life Cycles Are the changes and growth an organism experiences during its life, including reproduction Accompanies: Plants & Animals: What s the Difference? 14

15 2. Life Cycles Define sharp separation between plants and animals in regards to reproduction and age 3. Life Cycle of Plants 4. Plant Life Cycles Include sexual and asexual propagation through structures such as flowers and spores and then dispersal by mature plants Often include an infancy stage May last for a few short hours or several decades 5. Plant Reproduction Is either sexual or asexual Utilizes appendages such as flowers to propagate, with male and female systems most often included on the same plant Is often aided by other organisms and nature through pollination Fun Fact: The process of transferring pollen from the anther, the male sexual organ, to the stigma, the female sexual organ, is called pollination. Accompanies: Plants & Animals: What s the Difference? 15

16 6. Sexual Reproduction Requires male and female organs, often included on the same plant like conifers Occurs when male and female organs from mature plants exchange reproductive materials Most often utilizes structures such as flowers to develop seeds and fruits to protect them 7. Flowers Are structures utilized by plants most often classified as angiosperms Include male and female organs, such as stamens and ovaries 8. Seeds Are units of reproduction utilized by flowering plants Can be utilized for sexual or asexual reproduction Are often protected from harm by fruit as with apples and oranges, or by a shell, as with pecans and peas 9. Fruits Are the by-product of many forms of plant reproduction Often include seeds within, protecting them as they grow 10. Asexual Reproduction Also classified as vegetative reproduction, includes different methods, such as separation, dispersal and utilization of non-fertilized seeds 11. Separation Occurs when a plant, for example, potato plants fragment and produce new offspring with the genetic material of the parent plant 12. Dispersion Occurs when mature plants, including special varieties of mosses, produce sporophytes, which are spore producing structures which then germinate with a gametophyte structure Accompanies: Plants & Animals: What s the Difference? 16

17 13. Non-Fertilized Seeds Are utilized when mature plants, such as dandelions, produce an embryo within an ovary structure and produce seeds within the structure itself, with no fertilization necessary 14. Infancy Stages Are common in plants, especially trees, which often live for several decades Involve a period of slow growth and immaturity, in which a plant is unable to reproduce and is more susceptible to damage and death 15. Variety of Age Is incredibly diverse in plants, with some living for just hours, and others living for decades Depends on the purpose a plant is serving and the environment in which it exists Fun Fact: Some species of algae live for just hours, while trees like the Redwood and Bristlecone pine can live for decades. 16. Energy in Plants Is produced during photosynthesis Is consumed in the form of sugars which are the product of photosynthesis Comes from sunlight Is used for growth and reproduction Accompanies: Plants & Animals: What s the Difference? 17

18 17. Animal Life Cycle 18. Animal Life Cycles Are defined by utilization of sexual reproduction Include infancy and immaturity, in which young animals are unable to reproduce and perform the same tasks as mature animals May last for a few short days or several decades 19. Sexual Reproduction in Animals Involves one male and one female Utilizes the combination of male sperm with a female egg to propagate Promotes variation, as offspring receive genetic traits from both parents Is dependent upon a reproductive cycle 20. Animal Reproduction Is most often sexual, with a few smaller organisms such as flatworms and various insects reproducing asexually Most often requires one male and one female for propagation 21. Reproductive Cycles Vary greatly among animal species Are impacted by the environment surrounding an animal, with the time of day used for breeding depending on the day length and the characteristics of the species Accompanies: Plants & Animals: What s the Difference? 18

19 22. Infancy Stages Vary in length, from a few short days to several years Involve a period of slow growth and immaturity, in which an animal is unable to reproduce and is more susceptible to injury and death Often include heavy dependence on the mother 23. Variety of Age Is incredibly diverse among animals with some living for just hours and others living for more than 100 years Depends on the purpose an animal is serving and the environment in which it lives Fun Fact: The Mayfly is known to live no longer than 24 hours and the Galapagos Turtle is known to live over 100 years. 24. Energy in Animals Comes from organisms which have been consumed, including plants and other animals Such as deer, which are herbivores, consume plants for energy Such as lions, which are carnivores, consume other animals for energy 25. Variation Is increased diversity among continuing generations Is the result of sexual reproduction, with two individuals passing traits from their lineage to a new offspring 26. Life Cycle Similarities Between plants and animals similarities are most notable through sexual reproduction, although plants also reproduce asexually Include an infancy stage, continual nutrient and energy consumption and differing length of time varying by species 27. Life Cycle Differences Between plants and animals differences are numerous Include plant utilization of seeds, utilization of flowers and spores and asexual reproduction Accompanies: Plants & Animals: What s the Difference? 19
