This is the characteristic of Animals defined by them being made up of many cells.
What is multicellularity
100
This characteristic describes how animals reproduce, usually with a small, mobile sperm uniting with a much larger egg to form a zygote
What is Sexual Reproduction
100
tiny, single celled organisms, each with a single flagellum surrounded by a collar composed of cytoplasmic tentacles. Animals evolved from these, or something like these.
What is Choanoflagelllate
100
embryonic cell layers, the number of which is a divided characteristic of radiata and bilateria
What is germ layers
100
This is the section of the gastrula lined by the endoderm
What is archenteron
200
This characteristic is something extremely common in plant, fungal, and bacterial cells, but something animals lack.
What is Cell wall
200
This characteristic is fueled by animals having a muscle and a nervous system.
What is Movement
200
Collectively, animals are *blank*, but this can be split into two subgroups, *blank* which doesn't have specialized tissue and *blank* which has one or more types of tissue (3 answers)
What is Metazoa, Parazoa, Eumetazoa
200
The process of growing an embryo in all animals except the sponges.
What is gastrulation
200
the outer layer of the gastrula that covers the surface of the embryo and differentiates into the epidermis and the nervous system.
What is ectoderm
300
This characteristic is the protein (mostly collagen) that binds animal cells together to give them added support and strength.
What is extracellular matrix
300
These are the three main types of junctions between animal cells. (3 answers)
What is anchoring, tight, and gap junctions
300
The eumetazoa are divided based on symmetry, *blank* being divided equally by any longitudinal plane passing through the central axis, and *blank* which can be divided equally by a vertical plane at the midline. (2 answers)
What is Radiata, Bilateria
300
This is the process of rapid cell division with no significant growth that produces a hollow sphere of cells called *blank*. (2 answers)
What is cleavage, blastula
300
layer of cells between the endo and ectoderm, which forms muscles and most other organs between the digestive tract and the ectoderm.
What is mesoderm
400
This characteristic of Animals means that they eat other organisms or the products of other organisms to obtain their nutrients.
What is Heterotrophs
400
The last two characteristics of animals are *Blank* genes and something encodes for RNA. (2 answers)
What is Hox genes, rRNA
400
*blank* is the upper side of an animal, *blank* is the lower side, *blank* is the head, and *blank* is the tail. (4 answers)
What is dorsal, ventral, anterior, posterior
400
The structure created from gastrulation
What is gastrula
400
Bilateria have three germ layers, so we call them *blank* while radiata have two germ layers so we call them *blank* (2 answers)
What is Triploblastic, diploblastic
500
This characteristic allows animals to respond rapidly to environmental stimuli
What is nervous tissue
500
Method by which an organism changes from a juvenile to an adult form, common among arthropods.
What is Metamorphosis
500
The localization of sensory structures at the anterior end of the body.
What is cephalization
500
the inner layer of the gastrula
What is endoderm
500
an indentation in the endosperm that forms an opening to the archenteron
