Deciduous Leaf
Deciduous is defined as a tree or shrub that sheds leaves annually, or every year. The leaves do not last. Here in New England, we see many deciduous leaves, as shown in this photo.
Heartwood
The innermost part of a tree trunk that is the thickest. You can see the very center of the tree trunk in this photo of a cut tree.
Pollen
A usually yellow, powdery substance that is let out or discharged from the male part of a flower. The anthers of a flower are sticky in order to obtain the pollen. The photo of the flower represents where pollen exists and plays its main role: plant reproduction. Not only is pollen an important part of plant reproduction, but it is also a source of annoyance for many people with allergies. In the picture, the anthers can be seen where the pollen attaches itself to in the very center of the flower.
Autotroph
A plant that is able to create its own food and fill its nutritional needs through photosynthesis. This plant here provides for itself through photosynthesis as shown by its green leaves.
Thorn of a Plant
Thorns in plants are an adaptation of the plant which protect the plant from being eaten or destroyed by other plants or animals. Thorns may also be helpful for spreading the vegetation of the plant they are on because they may stick to predators moving in several different places and locations. The rose bush in the photo is an infamous example of a plant with thorns.
Long-day Plant
Plants that have flowers that bloom only when they receive more than twelve hours of sunlight per day. They bloom only when the days are long, where there is less darkness, especially during the summer months. Some examples are spinach, potatoes and lettuce, seen in this picture.
Globular Protein
Proteins that are at the tertiary structural level of proteins which are foldings of alpha helices or beta-pleated sheets. They are spherical in shape containing tertiary and quaternary structures. Globular proteins may be found in the hemoglobin (transports oxygen) in your blood. There is blood circulating throughout the body, so the picture of my hand represents the blood where the hemoglobin and therefore the globular proteins exist.
