Stamen is the reproduction organ of a flower. It is the one of the male organs, and it usually has two parts; the stalk and the anther which has pollen on it. The pollen grains on the anther in angiosperm plants is the basic building block for reproduction. The picture shows the stamen of a flower and it is located at its' center and is sticking outwards.
A sepal is a seperate part of the flower forming the calyx. It is usually green. This is used to protect the flower bud. There are usually the same number of sepals as their are petals. In the following picture, you can see some of the sepals on the upper stem and their also are some on the underside of the petals, but they aren't very visible.
Photosynthesis is the process in which a plant uses natural resources such as light, water, and carbon dioxide and then creates oxygen and glucose. The plant uses its chlorophyll to capture the light. An example of a plant that does photosynthesis is a flower.
Fermentation is when organic foods are broken down into simpler compounds. This creates energy, aka ATP, in the process. This is known as an anerobic cellular process. An example of fermentation is alcohol.
A bryophyte lacks vascular tissue, and is mainly only capable of growing/living in moist environments. The majority of bryophytes are mosses, which is why there is a photo of moss in the following picture. This moss was found at the bottom of a tree near a pond, which is why it can survive (because the evironment is usually moist).

Topsoil is pretty much self- explanatory. It is the upper layer of soil. Its technical name would be the A-Horizon part of soil. It is usually rich in humus. This picture is a photo of topsoil.

Fungi is the Kingdom of eukaryotic organisms that lack chlorophyll and vascular tissue. Fungi have spores, and the reproduction occurs through them. They also have chitinous cell walls. The picture below is a type of mushroom.
