Unit 1 - What is an Animal?

A heterotroph is an organism that consumes or ingests its food. A heterotroph obtains lipids, carbs, proteins and nucleic acids made by other organisms.

Heterotrophs, Eukaryotic, Multicellular organisms. Animals contain tissue.

Has nucleus, is multicellular, membrane bound organelles.

Multiple similar/identical interconnected cells that serve the same function.

A bastula will undergo the process of gastrulation with the main goal of forming a gastrula.

Multiple different layers (germ layers). The different layers form embryonic tissue.

A bastula is an animal embryo at the early stage of development when it is a hollow ball of cells.

When a singular cell cannot perform a task but multiple are capable. Such as protecting, forming a barrier.

Lacks nucleus, Unicellular, Has a cell wall and no membrane bound organelles.

False, some animals can undergo parthenogenesis or asexual reproduction.

After a zygote is formed it will undergo rapid cell division. The rapid cell division is called cleavage.
