Niche

PIcture 27 - This is a picture of a spider and its web. A niche is the natural habitat of an animal.
This picture was taken by my grandma's house.

Picture 28 - This is a picture of fish. They are living in a pond and it is their natural habitat. The niche an organism occupies is the sum total of all the ways it utilizes the resources of its environment. A niche may be described in terms of space utilization, food consumption, temperature range, approriate conditions for mating, requirements for moisture, and other factors.

seed dispersal

Picture 25 - This is a picture of a butterfly. It was taken while I was walking around outside my grandma's house. Seeds can be dispersed through animals like this because after this butterfly is done feeding on the nectar of the flower, the seeds from the flower might cling onto the butterfly's leg and then brush off somewhere else.

Picture 26 - This is a picture of the flower floating along the water was taken near by a pond. This picture shows that seeds can also be dispersed through water. Water can bring seeds to various areas and spread the species wide and far.

Cuticle layer of a plant

Picture 22 - This picture was taken at my grandma's house. It is a picture of the cuticle layer of a plant. The cuticle layer of a plant is a waxy coating that helps prevent desiccation which is plants losing water to air.

Picture 22 - This is also another plant that belongs to my grandma. Unlike their freshwater ancestors, most land plants have only limited amounts of water available. As an adaptation to living on land plants developed this cuticle layer.

Genetic Variation Within A Population

Picture 21 - This is a picture of two different colors of the same species of flower. These flowers were found near a pond. This shows genetic variation within a population of flowers.

Picture 22 - This picture was taken on the side of a road. My cousin is standing in front of a population of flowers. They are all the same species but have different colors showing that there has been some variations in their genetic makeup.

Flower Ovary

Picture 19 - This is a picture of a flower that was found in the park outside my aunt's home. This picture shows the flower ovary of this flower. The lower part is known as the pistil and the ovary matures the seeds to bear fruit.

Picture 20 - This is another picture of a flower that was found near the first picture. After fertilization, the ovule develops into a seed in the ovary. Sometimes the seed will develop into a fruit, depending on the type of seed.

Anther and Filament of stamen

Picture 17 - This is a picture of a flower with its filament sticking out. The stalk is the filament and the anther bears pollen. Each stamen consists of an anther and filament. This flower was found in a local park.

Picture 18 - This is another picture of the anther and filament of a stamen. The stamen is the male structures of the flower. The filament can't really be seen clearly here, but the long white stalks coming out of the flower and its petals is the filament and the anther is at the other end of the filament. This flower was found in the same park I found the white flower in.

Xylem

Picture 15 - This is a picture of a branch snapped in half. Inside this branch is vascular tissue. This tissue includes two kinds of conductiong tissues. One of these conducting tissues are xylem. Xylem conducts water and dissolved minerals.

Picture 16 - This is the picture of a tree trunk. It was taken by a building. Through this trunk the xylem would transfer water and dissolved minerals to the leaves and branches of the tree.
