Title. Learning Targets. Criterion A: Knowing and Understanding I can identify and describe the main characteristics of animals, such as symmetry, movement, and multicellularity. I can compare animals to other life forms based on their structure and function. Criterion B: Inquiring and Designing I can explore how animals adapt to different environments to support survival and biodiversity. I can classify animals by applying scientific criteria, such as body symmetry and the presence of a backbone..

Emirates National Schools. General Animal Features. 

Scene 6

Ancestral animals at the beginning of the evolutionary tree are eukaryotic and multicellular.  All present-day animals might have evolved from choanoflagellates, which are protists that formed colonies in the sea 570 million years ago.

Emirates National Schools. Feeding and digestion. 

Scene 7

All animals are heterotrophic. The structure or form of an animal’s mouth parts determines how its mouth functions. After obtaining food, all animals must digest it, either in specialized cells like sponge or organs like earthworms & humans.

Emirates National Schools. Support. Between 95 and 99 percent of animals are animals without backbones called invertebrates . Many invertebrates are covered by exoskeletons, which are hard or tough outer coverings.. 

Scene 8

Between 95 and 99 percent of animals are animals without backbones called invertebrates . Many invertebrates are covered by exoskeletons, which are hard or tough outer coverings.

Emirates National Schools. Support. Some invertebrates have an internal support structure called an endoskeleton. If an animal has an endoskeleton and a backbone, it is called a vertebrate.. 

Scene 9

Some invertebrates have an internal support structure called an endoskeleton. If an animal has an endoskeleton and a backbone, it is called a vertebrate.

Emirates National Schools. Habitats. Vertebrates and invertebrates live in oceans, in freshwater, and on land. They can be found in deserts, grasslands, rain forests, polar regions, and all other land biomes and aquatic ecosystems.. 

Scene 10

Vertebrates and invertebrates live in oceans, in freshwater, and on land.  They can be found in deserts, grasslands, rain forests, polar regions, and all other land biomes and aquatic ecosystems.

Emirates National Schools. Animal cells & tissues. 

Scene 11

Animal cells do not have cell walls. The cells of all animals, except sponges, are organized into structural and functional units called tissues.  A tissue is a group of cells that is specialized to perform a specific function.

Emirates National Schools. Movement. Two types of animal movement: 1. Animal’s entire body moves through the environment. (Grasshopper jumping through a field) 2. Only one part of the body moves. ( A rabbit twitching its ears in response to a sound). 

Scene 12

Two types of animal movement: 1. Animal’s entire body moves through the environment.          (Grasshopper jumping through a field) 
 2. Only one part of the body moves.          ( A rabbit twitching its ears in response to a sound)

Emirates National Schools. Reproduction. Most animals reproduce sexually, although some species can reproduce asexually. Some animals are hermaphrodites, meaning they produce both sperm and eggs in the same body , such as snails, slugs, and worms,. 

Scene 13

Helix pomatia also Roman snail, burgundy snail, edible snail or escargot, is a species of large, edible, air-breathing land snail.

Emirates National Schools. Reproduction. Fertilization occurs when the sperm penetrates the egg to form a fertilized egg called the zygote. External fertilization occurs when sperm and egg meet outside an animal’s body. This process requires an aquatic environment.. 

Scene 14

Fertilization occurs when the sperm penetrates the egg to form a fertilized egg called the zygote. External fertilization occurs when sperm and egg meet outside an animal’s body. This process requires an aquatic environment.

External Fertilization
male fish waits to spread
sperm over the eggs
female fish
lays eggs

Emirates National Schools. Reproduction. Internal fertilization occurs when sperm and egg meet inside an animal’s body.. 

Scene 15

Internal fertilization occurs when sperm and egg meet inside an animal’s body.

Emirates National Schools. Reproduction. In asexual reproduction: A single parent produces offspring genetically identical to itself. Common methods of sexual reproduction: Budding: offspring develop as growths on parent Fragmentation: parent breaks into pieces that develop into adults Regeneration: new organism grows from a lost body part Parthenogenesis: egg develops in a female without fertilization.

Emirates National Schools. Reproduction. Fragmentation of starfish. 

Scene 17

Emirates National Schools. Reproduction. Early Development The zygote undergoes mitosis and a series of cell divisions to form new cells. The cells continue to divide, forming a fluid-filled ball of cells called the blastula. The blastula continues to undergo cell division, and some cells form a gastrula, a two-cell-layer sac with an opening at one end. The process is illustrated on the next slide..

Scene 19

Emirates National Schools. Reproduction. Tissue Development The inner layer of the gastrula develops into the endoderm. It forms the digestive organs. The outer layer of the gastrula develops into the ectoderm. It becomes the nervous system and skin. The mesoderm forms between the ecto- and endoderm. It forms the muscle, circulatory, excretory, and respiratory systems in some animals. The layers are illustrated on the next slide..

Scene 21

Emirates National Schools. Reproduction. Cells formed shortly after fertilization have the ability to become one of any number of different kinds of cells. As the cells in a zygote undergo mitosis in early development, each begins to go through the process of cell differentiation. During cell differentiation, cells become specialized to perform a specific function..
