  1. Week 36 : What is an animal? Section 25.1

  2. Monday 5.20.2013 Week 36 Pick up: Chapter 25 Packet (if you did not receive it Friday) • Bell Ringer Question: Describe3 characteristics typical of all animals Set up a Cornell Note sheet!!! • Topic: What is an animal? • Objective: IWBAT identify the characteristics of animals and their development • Agenda • Bell Ringer (5min) • FOLDER CLEAN OUT • Cornell Notes (25min) • IP/Homework (20min) • CORNELL Notes Section 25.1 & 25.1 Packets (HMWK) • Make up Exam: during lunch periods and before/ after school. You have until Tuesday after school!

  3. Topic: What is an animal? 1. What are some characteristics all animals share? • All animals are: • Eukaryotic, multicellular organisms with ways of moving that help them reproduce, obtain food, & protect themselves. • Most animals have specialized cells that form tissues & organs– such as nerves and muscles.

  4. What is an animal? 2. Do all animals eat food? • All animals are heterotrophic– they must consume food to obtain energy & nutrients . • After they eat the food, they digest it. Some of the food that an animals consumes & digests is stored as fat and used when other food is not available

  5. What is an animal? 3. Describe a career in biology that studies animals. • Marine Biologists study organisms found in oceans. They go SCUBA diving and examine those organisms in labs doing library research

  6. Marine Biologist in the In the Lab Field (ocean) examining a starfish

  7. What is an animal? 4. Do all animals have the ability to move? • In water, some animals, like oysters, don’t move from place to place and have adaptations that allow them to capture food from their water habitat. • Sessile: organisms that are permanently attached to a surface. They don’t use much energy to get food.

  8. Oysters can’t move!

  9. Animal cell adaptations 5. Describe some adaptations animals have developed. • Animals have special cells that let them sense and seek out food and mates, and allow them to identify and protect themselves from predators

  10. Animal cell adaptations pg. 299 in packet!(Don’t write this down! Please review in your packet!!) 6. Describe the steps in the development of an animal. • Fertilization • First cell division (mitosis) Called an embryo now. • Additional cell divisions • Formulation of a blastula • Gastrulation (embryo continues to grow, some of the cells of the blastula move inward. • Formation of mesoderm

  11. 7. Explain the different types of cells animals have. 1.Mesoderm: Found in the middle of the embryo. Develops into the muscles, circulatory system, and sometimes the respiratory system. 2. When the opening of the gastrula develops into the mouth, the animal is called a protostome. Ex) Snails & insects 3.Deuterostome: in sea stars, fish, and humans, the mouth does not develop from the gastrula opening but from cells somewhere else on the gastrula.

  12. Review these steps in packet and be sure to identify all VOCABULARY terms & review cell types! Finish for HOMEWORK!

  13. Essential Questions: YES, you must write the question. Answer in complete sentences! • Answer the following at the end of your Cornell notes. • Identify and list the characteristics of a mouse that makes it an animal. • Explain why movement is so important for animals. • Describe the mesoderm and what cells it forms. Complete packet for homework!! Start now!

  14. Tuesday 5.21.2013 Week 36 ……announcements: LAST DAY for exam make ups • Bell Ringer Question: Explain why movement is an important characteristic of animals • PICK UP Cornell Notes Template ! (from bin) • Cornell Note sheet: Objective: IWBAT Compare and contrast radial and bilateral symmetry with asymmetry. • Agenda • Bell Ringer (5min) • Cornell Notes Independent practice Section 25.2(25min) • Due Today: 25.1 Packet • Make up exams in room 121 after school! MUST be in the room by 3:10!!

  15. Body Plans and Adaptations 1. Explain the concept of symmetry of animals • A term that describes the arrangement of body structures • Different kinds of symmetry enable animals to move about in different ways.

  16. Body Plans and Adaptations 2. Describe the three types of symmetry • Asymmetry- Irregular body shape. • Most are sessile (remember, animals that do not move) • Ex. Sponges, Coral

  17. Body Plans and Adaptations 2. Describe the three types of symmetry
