Cuticle layer of a plant

                                                                        CUTICLE LAYER OF A PLANT

The cuticles of a plant are a protective waxy covering the leaves that helps prevent dessication which is the process of plants losing water to the air.  This boxwood plant is an example.



                                                                                        EUKARYOTES

 

 

 

Are organisms made up of the cells that possess a membrane-bound nucleus (that holds genetic material) as well as membrane-bound organelles.  Genetic material in eukaryotes is contained within a nucleus within the cell and DNA is organize into chromosomes.  All animals are eukaryotes.

                                                                                             EXOSKELETON

 

 

 

Is the external skeleton that supports and protects an animals body.  Such as in this cricket.

 

 

 

 

CELLULAR RESPIRATION

 

 

 

 

 

Plant takes in oxegen as part of this process and releases carbon dioxide.  The process is creating cell energy.  This tree is an example.

 

 

 

COMMENSALISM

 

 

 

 

A relation between two kinds of organisms in which one obtains food or other benefits from the other without damaging or benefiting it.  The clown fish and anemone are an example.

 

 

 

LIPID USED FOR ENERGY STORAGE

 

 

 

 

Are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells.  Lipids contain a lot of calories in a small space.  Oil is an example.

 

 

 

XYLEM

 

 

 

 

 

  The supporting and water-conducting tissue of vascular plants, consisting primarily of tracheids and vessels, woody tissue.  This tree stump is an example.  the xylem is the interior part of this log.

 

 

 

EPITHELIAL TISSUE

 

 

 

 

Cover the whole surface of the body.  It is made up of cells closely packed and ranged in one or more layers.  This tissue is specialize to form the covering lining of all internal and external body surfaces.  My sister's hand is an example.

 

 

 

ANIMAL THAT HAS A SEGMENTED BODY

 

 

 

Is when the body is divided into segments were the segments piggyback one another.  Each body segment tends to repeat the same suite of structures, often a slight variation down the length of the animal.  Usually sets of segments are grouped into a larger unit, such as the abdomen.  Such as in the star fish and this cricket.

 

 

 

 

ANALOGOUS STRUCTURE

 

 

 

 

 

Are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature and which evolved in response to a similar environmental challenge.  Birds and insects have wings but different structures.
