Gametophyte

Gametophyte: This is the multicellular phase of plants and algae that undergo alternation of generations. Examples of plants that undergo this phase are mosses, liverworts, and hornworts. The moss in this picture undergoes the gametophyte phase.

Exoskeleton

Exoskeleton: This is an external skeleton that supports and protects an animal's body. Examples of animals with exoskeletons are shrimp, beetles, grasshoppers, crabs, and ants.

Epithelial Tissue

Epithelial Tissue: This is a membranous tissue that covers internal organs and other internal surfaces of the body. Skin is an example of epithelial tissue.

Deciduous leaf

Deciduous Leaf: A deciduous plant is a type of plant that falls off or sheds at a particular season or stage of growth. This leaf came from a deciduous plant.

Cellulose

Cellulose: This is an inert carbohydrate (a carbohydrate that has little or no ability to react) (C6 H10 O5). It is mainly obtained from wood pulp and cotton, and is used to produce paperboard and paper. This tree is an example of where cellulose can be obtained from.

Batesian mimicry

Batesian mimicry: This is the protective resemblance in appearance of a palatable or harmless species, to an unpalatable or dangerous species, that is usually avoided by predators. This type of mimicry is very common in butterflies and other animals (such as frogs and snakes).

Bryophyte

Bryophytes: These type of plants are the only land plants whose life history includes a dominant gametophyte stage (stage in which gametes are produced). The moss on the tree is an example of a bryophyte.
