Autotroph:
An autotroph is an organism that can produce its own food by using light as its energy source. This plant is an example of an autotroph because it uses energy from the sun to photosynthesize and produce energy to make it grow.








Xylem:
In this picture you can see the inside of a plant stem. Although the xylem are too small the see, they are the small tubes that act as supports that carry water and minerals throughout the plant.





Rhizome:
Rhizomes, also called "root stalks," are plants with horizontal stems, usually found underground. Bamboo is an example of an underground rhizome, as well as Venus flytrap and ginger.






Pollen:
Pollen is tiny dust like spores that are made by the anthers of a plant. You can see in this picture the pollen that rubbed off on my finger as well as the pollen still on the anthers of the plant.





Conifer leaf:
This tree bears cones and has evergreen leaves, making it a conifer tree. The leaves are arranged spirally, as on most conifer trees.






Pollinator:
A pollinator is an agent that carries pollen from the male anthers to the female stigma of a flower. A butterfly is a good example of a pollinator, when it lands on the flowers to drink the nectar, its legs get pollen on them, transferring the pollen from the male part of the flower to the female part, fertilizing the the flower so it can sexually reproduce.


Pine Cone - Female:
This picture shows a female pine cone. Female pine cones are much larger than males, and hold the seeds inside the small shingle-like sections. The males are much smaller and don't hold any seeds.







Anther and Filament of Stamen
In this picture you can clearly see the anther and filament of this flower. The anther and filament is located in the center of the flower, the small stem-like things coming out of the center of the petals are filaments. The small brown cap on top of the filament is the anther.


Frond:
This is the frond of a small palm. A frond is a large, divided leaf. Another example of a plant with fronds are ferns.





Unicellular organism:
An egg is a simple unicellular organism (one celled organism.) If this egg was to hatch into a chicken, inside the shell it would divide more and more until a baby chick if formed.

  1. Great pictures! One thing: an egg is a single cell, but not an organism. A unicellular organism must be able to survive on it's own as one cell. The cell inside an egg must divide, like you said, to produce a viable organism.
