Homologous Structures

Homologous structures are body parts that are similar in different species because they shared a common ancestor.  As you can see the arm shape between these species look alike.

Seed dispersal

Birds help with the process of dispersing seeds by picking  up seeds in their beaks or seeds attaching to the their feathers, they distribute the seeds in different areas.

Rhizome

Rhizome is the horizontal stem of a plant underground.  Many plants can grow from the rhizome.

Predation

A bear hunting fish is an example of predation.  The bear is killing the fish for food to eat.

R-strategist

A dandelion is a r-strategist because it has a small body, large population size, and they produce offspring in large numbers.

Modified leaf of a plant

Modified stem of a plant

Tropism

Tropism is the growth of a plant in response to an external stimulus.  These roses are blooming in response to the sunlight.

Basidiomycete

Mushrooms are an example of basidiomycete because they are fungis that produce spores.

Ectotherm

A fish is an example of ectotherm because its body temperature depends on its surrounding environment.

Hermaphrodite

A snail is an example of a hermaphrodite because it has both male and female reproductive organs.

ATP

ATP (adenosine triphosphate) is a nucleotide, it transports energy in the cells of organisms.  ATP is used in physical activity.  ATP is used in marching band.

Enzyme

Enzymes speed up chemical reactions in the body.  Enzymes are found in salivia, they are called amylase.

Dominant vs. Recessive phenotype

Phentoypes are the physical characteristics of organisms.  Rachael's freckles are the dominant phenotype because she has freckles.  I have the recessive phenotype because I do not have any freckles.

Long-day plant

Lettuce is an example of a long day plant because it flowers after being exposed in sunlight after a long time period.

Eubacteria

Eubacteria are single celled organisms  that can be found in uncooked meat.

Endotherm

A rat is an example of endotherm because it creates its own heat to keep the temperature of its body heated.

Population

Territorial Behaivor

A dog peeing is an example of territorial behavior because it is marking an area as its own.

Stigma and style of carpel

The stigma and style make a carpel .  The carpel also known as the pistil is the female part of the flower.  The style is on tops of the ovary. The style brings materials from the root of the plant to different parts of the carpel. The stigma is at the very top of the carpel.  The stigma has a top that is sticky which allows pollen to stick on and pollinate the flower.

Niche

A spider in a web is an example of a niche because a niche is a specific area where an organism dwells in.

Cuticle layer of a plant

The cuticle layer of a plant protects the epidermis of leaves from the surrounding environment.

Heterotroph

A duck is an example of a heterotroph because it is an organism that eats another organism for food  A duck eats fish eggs. small fish, and snails.

Animal that has a segmented body

A butterfly has a segmented body because its body is divided into three parts: the head, the thorax, and the abdomen.

Endosperm

Pistachios are an example of endosperm because the endosperm is the seed part that acts as a food store; it surrounds and nourished the embryo.

Flower ovary

The flower ovary is the female reproductive organ.

Detritovore

An earth worm is an example of a detritovore because it is an organism that feeds on decomposing and dead organic matter.  Earth worms eat animal matter and decaying plants in soil.

Spore

Mushrooms are an example of a spore because mushrooms  are organisms that reproduce asexually.

Autotroph

A Venus fly trap is an example of an autotroph because it is an organism that can make organic molecules from inorganic sources using photosynthesis. A venus fly trap carries out through photosynthesis and creates its own carbohydrates.

Vestigal structures

Wisdom teeth are an example of vestigal structures because because they have lost most of their ancestral function but have retained through the process of evolution.  Wisdom teeth aren't useful to humans because our diet has evolved over many years.
