4. 4 celled zygote
5. Morula
6. Blastula
7. Gastrula |
|
|
Term
|
Definition
| Fluid filled spaces that lie between the digestive tract and the body wall. Body cavities provide a space for organs to grow and move without being twisted or crushed during body movement. Body cavities, being lined by membranes, isolates infection and specific organ function. |

-Examples |
|
Definition
Animals with a body cavity located between the mesoderm and the endoderm
-Nematodes- Roundworms |
|
|
Term
|
Definition
Animals that have a body cavity that develops within the mesoderm

Term
|
Definition

-Cnideria- Arthropods |
|
|
Term
|
Definition
Blastopore becomes the anus

Term
Direct Development
-Examples |
|
Definition
Offspring are smaller versions of an adult
-Snakes, Cows, Cats |
|
|
Term
| Indirect Development (metamorphosis) |
|
Definition
| Offspring undergo physical changes before becoming an adult |
|
|
Term
|
Definition
Egg-->Larvae/Nymph-->Adult
Larvae will have a similar body form to the adult, but will lack sexual organs and adult structures (like wings). |
|
|
Term
|
Definition
Egg-->Larvae-->Pupa-->Adult
The developing organism (larvae) will undergo dramatic changes during the pupa stage and will differ in shape and diet from the adult. |
