AP Biology

This is Netta’s AP Biology photoblog, not an advertisement for Burt’s Bees lip balm (Although, I do recommend it).

Term 1

This is a photo of my dad’s eyes. My dad’s eyes represent a recessive phenotype. A recessive phenotype is a trait that is less dominant compared to others, for a recessive trait to appear, the orgainism would need both parents to pass on the gene to avoid a more dominant gene overpowering it. in contrast, a dominant eye color, like brown, would appear even if there was another eye color was oassed by the other parent. My dad’s eyes represent a recessive phenotype because neither of his parents had blue eyes, yet they both passed on their recessive traits to him, making his eyes blue.

Term 2

This is a picture of a flower. The flower represents cellular respiration. Cellular respiration is the process of a cell using carbon dioxide to convert glucose into ATP and produce energy. A flower represents cellular respiration because it’s cells use cellular respiration in order to create energy.

Term 3

This is a picture of a lily. The lily represents pollen. Pollen is tiny particles that are released by the male parts of plants and is intended to find its way to a stamen in order to reproduce. A lily represents this because the pollen from it’s stamen has fallen on it’s petals which makes it visible.

Term 4

This is a picture of Jaeger’s foot. Jaeger’s foot represents a vestigial structure. A vestigial structure is a structure that has adapted to be no longer needed. Jaeger’s foot represents this because he has a dewclaw, while his ancestors had it as a fifth claw to climb trees with, he mainly uses it to get snagged on blankets now.

Term 5

This is a photo of a hamster. A hamster represents an endotherm. Endotherms are animals that are capable of regulating their own body temperatures. The hamster is an endotherm because he can regulate his body temperature, he is warm blooded, and he is a mammal, all of these indicate he is an endotherm.

Term 6

This is a picture of a carnation. Carnations are long day plants. Long day plants are plants that flower typically in the summer because they are dependent on long stretches of sunlight and require more than 12 hours of it. Carnations are long day plants because they flower in the summer and require long stretches of day light.

Term 7

This is a picture of a slice of flower stem. The slice of flower stem represents phloem. phloem is the vascular tissue in plants that carries sugar down from the leaves. The slice of stem represents this because if you look closely in person, you can see the phloem  tissue.

Term 8

This is a picture of an orchid. The orchid represents a CAM Plant. CAM plants, also known as, crassulacean acid metabolism plants, are plants that have adapted to arid climates by having their stomata close during the day and only open at night in order to reduce evaporation. An orchid is classified as a CAM plant.

Term 9

This is a picture of a sliced open flower stem. This stem represents xylem. Xylem is a vascular tissue of a stem that transports water and nutrients up to the parts of the plant, it also forms the woody part of the stem. This stem represents this because before it was sliced and diced, it was a part of a flower in the ground and it was used to spread nutrients to all parts of the plant.

Term 10

This is a picture of my dog, Nugget. Nugget represents the term glycogen. Glycogen is a polysaccharide that is stored in bodily tissues, it is a store of carbohydrates. Nugget has glycogen because he is an animal and all animals typically store glycogen from the starch in plants that they eat.

Term 11

This is a picture of a sidewalk behind my house, it is littered with pollen and seeds from the flowering tree beside it. This side walk represents seed dispersal. Seed dispersal is when seeds from a plant are carried by water, wind, or animals and are carried to another location where they can root and grow. This picture shows that the seeds were blown away from the tree by the wind and will be dispersed further down the side walk, or picked up and carried away by an animal.

Term 12

This is a picture of a carnation. The carnation represents a hermaphroditic plant. Hermaphrodites are organisms that have both male and female sex characteristics, either normally or abnormally. Carnations represent hermaphrodites because they have a flower ovary, a female organ, and a stamen, a male organ. 

[ap-bye-ology]

Term 13

This is a picture of frozen chicken. The frozen chicken is meant to represent how humans are heterotrophic. Heterotrophs are organisms that require consuming other organic substances in order to meet their nutritional requirements. Frozen chicken represents this because it will be cooked and my family, who are humans, will eat them and get required nutrients such as protein from it. 

[ap-bye-ology]

Term 14

This is a picture of my step-sister, Kaylee. Kaylee is a human being, and human beings are eukaryotic. Eukaryotes are cells that have a nucleus, which houses their chromosomes and are comprised of DNA. Kaylee is a Eukaryotic orgainism because her cells have nuclei,  which have 23 pairs of chromosomes.

Term 15

This is a picture of a flower’s stamen. The stamen of a flower represents its anther and filaments, as labeled. Anthers produce a plant’s pollen while the filament is a long stalk that supports it. A stamen is representative of a anther and filament because it is comprised of those two pieces. 

[ap-bye-ology]

Term 16

This is a picture of a flower with it’s petals removed. This specimen of flower represents the flower ovary, which is labeled. A flower ovary contains ovules, which become seeds once fertilized. The light green part of the flower is the ovary and is where pollen ends up and ultimately helps to create new flowers through the production of seeds.

Term 17

This is a picture of an orchid. This orchid is an example of a modified root of a plant. Modified roots are roots that have evolved to be more effective in their environment. An orchid’s root is an example of this because it has an aerial root, which is responsible for aiding in photosynthesis and allowing the plant to “climb” up on other plants and rocks in order to compete for sunlight.
