COMPARE INVERTEBRATES TO VERTEBRATES

Vertebrates and Invertebrates.

Vertebrates and Invertebrates Vertebrates are animals with backbones (shown in the last slide) these include: fish, mammals, amphibians, birds, and reptiles Vertebrates are animals with backbones (shown in the last slide) these include: fish, mammals, amphibians, birds, and reptiles Invertebrates are animals without backbones these animals include insects and mollusks. Invertebrates are animals without backbones these animals include insects and mollusks.

What is an endoskeleton?

An endoskeleton is an internal supporting system skeleton derived from the mesoderm that is a characteristic of vertebrates and some invertebrates. An endoskeleton is an internal supporting system skeleton derived from the mesoderm that is a characteristic of vertebrates and some invertebrates. Animals that are included mammals and other animals that have similarities to vertebrates. Animals that are included mammals and other animals that have similarities to vertebrates.

What is an exoskeleton?

Any animal whose skeleton is not internal and that provides protection from the outer layer of their body. Any animal whose skeleton is not internal and that provides protection from the outer layer of their body. These animals include: insects, crustaceans, and sea stars. These animals include: insects, crustaceans, and sea stars.

What is internal and external fertilization?

Internal fertilization is the fertilization of the egg inside the female Internal fertilization is the fertilization of the egg inside the female External fertilization is the process involved the union of a male and female organism in which sex cells outside the female are used to fertilize an egg. An example of this would be a male and a female human. External fertilization is the process involved the union of a male and female organism in which sex cells outside the female are used to fertilize an egg. An example of this would be a male and a female human.

What is asexual and sexual reproduction?

What is asexual & sexual reproduction? Asexual reproduction is when an organism has only parent; when part of a parent splits off to from another organism. Asexual reproduction is when an organism has only parent; when part of a parent splits off to from another organism. Sexual reproduction- the cells 2 different parents unite to form the new organism. (Not meaning that the parents have sex ) Sexual reproduction- the cells 2 different parents unite to form the new organism. (Not meaning that the parents have sex )

Compare bilateral and radial symmetry

Bilateral and radial symmetry Bilateral symmetry symmetrical arrangement of an organism or a body part along a central axis and is divided equally. Bilateral symmetry symmetrical arrangement of an organism or a body part along a central axis and is divided equally. Radial symmetry- symmetrical arrangement of constituents epically of radiating parts about a central point Radial symmetry- symmetrical arrangement of constituents epically of radiating parts about a central point

Which characteristic are used to determine the classification of a sea star? A.Radial symmetry and an exoskeleton B.Radial symmetry and an endoskeleton C.Bilateral symmetry and an exoskeleton D.Bilateral radial symmetry and an endoskeleton

The answer is ……. A. Radial symmetry and exoskeleton, because it has a hard outer structure and radiating parts

A new organism is discovered after careful observation scientists conclude that it is a mammal. Which 2 characteristics would the organism possess? A. Endoskeleton and scales B. Exoskeleton and asymmetry C. Fur or hair & warm- blooded D. Have live young and radial symmetry

The answer is…. C. Fur or hair and warm blooded, mammals have hair to protect them from predators and to keep the warm during the cold times.

Study the table below. Which organism is MOST LIKELY to a clam? organismsupportrespirationhabitat1endoskeleton Gills, skin aquatic 2shellgillsaquatic 3endoskeleton Lungs, skin terrestrial 4shelllungsterrestrial

And the answer is Organism 2- because it has a shell which is exoskeleton it has gills which allows it to live in the water. Organism 2- because it has a shell which is exoskeleton it has gills which allows it to live in the water.

Which animal ‘s body shape show bilateral symmetry? A. Jellyfish A. Jellyfish B. sea anemone B. sea anemone C. fish C. fish D. sea anemone D. sea anemone

And the answer is ….. C- fish because when you cut the fish down the middle the sides are equal. C- fish because when you cut the fish down the middle the sides are equal.

Which group of animals contains members that move using cilia and flagella? A. birds A. birds B. protists B. protists C. mammals C. mammals D. amphibians D. amphibians
