Adaption of an Animal

Use of physical or behavior characteristics by the animal that will help it survive in its environment.

Humans do not have an extention of the tail bone due to adaptation to environment.

Adaption of an Plant

Use of physical or behavior characteristics by the plant that will help it survive in its environment.

Since owls are nocturnal, they are born with larger eyes to see.

Actin

A protein that aids in muscle tissue, platelet shape, edocytosis, cell motility, cell division, metastasis, and cell signaling.

Muscle, like in an arm, contains actin which functions as a polymer of G-actin.

Amniotic Egg

An egg with a water-impermeable amniotic membrance made for protection of a fluid-filled cavity.

All birds are known to lay amniotic eggs. These are various bird feathers.

Angiosperm

Plants whose seeds are secluded in a fruit. They are also known as Division Adnthophyta.

Most garden flowers are examples of angiosperms.

Animal That Has a Segmented Body

An animal with a series of similar functioning parts usually divided into groups.

This is a home to an ant. Since ants do run fast, it was hard to get a recognizable picture, but ants are known to be externally segmented.

Echinoderm

Sea animals with spiny skin that are visually symmetric.

These are old fossils from various symmetric animals.

Anther & Filament

Two parts of the Stamen that produce pollen.

The pod-looking part is the anther, where the stem from underneath is the filament.

Arthropod

Segmented bodied animals including insecs, spiders, centipedes, shrimp, and crayfish.

Classic example of one of the many arthropods of America!

Archaebacteria

A group of bacteria divided into three groups: methanogens, halophiles, and thermophiles.

Sewage treatment plants contain anaerobic bacteria (methanogens) that produce methane. EW.

Autotrophs

Produce their own energy through inorganic materials such as sunlight.

Plants are classic examples of autotrophs, grabbing their energy through photosynthesis.

Auxin Producing Area of a Plant

These include the stem, buds, and root tips. Auxin is a hormone that promotes cell elongation.

The bud of a plant that produces auxin.

Taken 8/27/13

Bryophyte

Types of plants that do not have vascular tissue. Grow in clumps on places such as rocks.

Moss is a prime example of a plant that grows in packs.

Taken 9/2/13

Cambium

A layer in certain plants that produces callus tissue when injured.

The layer before the outer layer of bark is the cambium layer.

Taken 8/30/13

Conifer Leaf

Leaves that are needle shaped from plants of the Pinophyta, gymnospermous plants.

Evergreen trees grow conifer leaves.

Taken 9/2/13

Cuticle Layer of a Plant

Covers the epidermis protecting agaisnt dessication, UV radiation, and chemical and biological agents.

The visible part of the plant is the cuticle layer.

Taken 8/30/13

Deciduous Leaf

A certain type of leaf that when the maintenance becomes to high for the plant, it will die and drop off.

This tree’s leaves are completely deciduous.

Taken 9/2/13

Deutersome

One of the two groups of Animal Evolution. The cell division occurs differently and the physical formations are different than the other group: protostomes.

The dolphin is part of one of the sub categories: Vertebrata.

Taken 9/2/13

Dicot Plant with Flower

One group of angiosperms that have characterisitics such as an embryo with two cotyledons, pollen with three pores, flowers in multiplies of four or five, roots that develop from radicle and often showing secondary growth.

This lilly is an example of a dicot. Its obvious because the plant flowers five petals.

Taken 9/2/13

Ectotherm

A cold blooded animal whose homeostasis of body temperature depends on EXTERNAL sources.

My 3 neon fishes are a cold blooded example.

Taken 9/2/13

Endosperm

A tissue that aids the embryo of angiosperms that requires coming together of one or more nucleui in embryo sac with a sperm nucleus form the pollen grain.

Popcorn contains soft and hard endosperm.

Fruit Dry with Seed

UseFruit that has been dried naturally or artificially by a machine.

Peanuts have been dried by a machine.

Taken 9/2/13

Fruit Fleshy With Seed

The part of the plant can either come from a single flower or multiple groups. The fleshy part holds the seed.

This strawberry contains the fleshy part inside with the seeds around it.

Taken 9/2/13

Eukaryote

The basic cell of most living creatures with a nuclei and funcitoning organelles. DNA does not roam freely around the cell.

My dog Rocky is completely composed of eukaryotes.

Fermentation

A process that takes breaks down carbohydrates into energy that can be used by the organism.

When the yeast in the grape is fermented, wine becomes the new product.
