6. Tropism

I choose to use a grape vine as an example of tropism. Tropism is the happening of an organism responding to an environmental catalyst affecting its growth patterns. These are those instances where you see vines climbing up and or covering walls, ladders, and even buildings.

Tropism is also broken into four different types:
-Photo Tropism: responds to where the most sunlight is making photosynthesis more productive.
-Thigma Tropism: responds to touch of objects.
-Gravity Tropism: responds to the effects of gravity.
-Hydera Tropism: responds to water; where it is.

5. Xylem

Xylem is a type of transport tissue only found in vascular plants, such as the bamboo pictured. Xylem's job in vascular plants, is to get water and dissolved nutrients transporting through it from its roots. Without such tissue, the plant would see its last days wilting and withering. Xylem is a necessity of life to these types of organisms.

4. Adaption of a Plant

Say hello to the very well adapted pine tree. Pine trees have had to go through many changes in order to survive there living conditions of generally being in very cold climates. For example, the pine's needles have responded to the trees need to slow down water loss. Because of how dense the needles are, air flow is limited along with evaporation, saving water.

3. Genetically Modified Organism

In this picture we see Dwarf Celosia. Dwarfing is an example of a genetic modification that an organism can acquire through a human or non-human process. To cause an organism to dwarf, genetics are altered through the use of hormones or nutritional changes. Why someone would choose to dwarf natures workings, I do not know? Maybe they just prefer the little things in life, no pun intended.

2. Amniotic Egg

An amniotic egg is one that is laid by reptiles, birds, and egg bearing mammals. What makes them so different, is the fact that the embryo, also known as the fetus, is enclosed in a membrane containing amniotic fluid protecting the new life from pressure. Used in this photo is a chicken's egg, which is an amniotic egg.

1. Flower Ovary

As you move to the innermost center of a flower, you have met your match with the female reproductive system called the carpel. Inside the carpel, we are able to locate the flower's ovary. Without the ovary, fruit bearing would become an impossible task for that flower.
