1. Name and Define the Three Characteristics That All Animals Share. (3 Points)

Show What You Know Animal Characteristics, Invertebrates and Vertebrates

1. Name and define the three characteristics that all animals share. (3 points)

1. Multicellular-made of many cells (share with Plants)

2. Eukaryotic-cells have a nucleus (control center) (share with Plants)

3. Heterotrophic-have to each other organisms to survive. (different from Plants-plants are autotrophs)

(can also say All move at some point in their life-be specific though, not all animals move their entire lives-like sponges.)

2. What is the difference between invertebrates and vertebrates? (1/2 point)

Vertebrates have a backbone and Invertebrates do not.

3. Circle true or false (explain in a complete sentence if false) (2 points)

Animals can only reproduce sexually (two parents).

TrueFalse

False-some animals can reproduce asexually, like Hydra. Hydra can bud which is a form of asexual reproduction.

4. Circle true or false (explain in a complete sentence if false) (2 points)

Ectothermic animals are known as “cold blooded” because they can not regulate their own body temperature and therefore are dependent on environmental heat sources such as the sun.

TrueFalse

True
