Different plants have different characteristics that enable them to thrive in some areas, but die in others. Grape vines needs a nearby structure to wrap around, such as a tree, to live. So, vines cannot survive in the plains where there are few trees.
Contains an thin membrane that forms a sac around the embryo or fetus of a mammal or any egg-laying creature. Also contains amniotic fluid.
This chicken egg is an example of an amniotic egg.
Body parts that perform the same task in different species, but have different structures. This oak leaf and maple leaf both share the task of photosynthesis, but are shaped differently.
7.) Anther & Filament of Stamen
The male part of the flower. The filament is the "stalk" of the stamen, and the anther on top bears the pollen. The long yellow part of the stamen of this flower is the filament and the anther is the white, fuzzy part at the end.
The outer layer of a leaf the protects the plant from desiccation (when the air takes water from the plant.) This waxy layer of the leaves prevents the plant from suffering from desiccation.
A plant that blooms only when it receives more than 12 hours of sunlight each day. The wheat in this bread used to be a long-day plant.
A large leaf with 2 or more divisions. This is a picture of a frond that came off a tree in my backyard.
A fungus in a symbiotic relationship with algae or other photosynthetic organisms.
This is a picture of lichen growing on a tree.
84.) Seed Dispersal (Wind)
Some plants scatter their seeds by using the wind. The wind can carry away these maple keys that contain seeds farther away, so the seeds do not overcrowd around each other and the initial tree.
64.) Modified Plant
Genetically modified plants have had their original DNA altered by genetic engineering, usually to give them resistance to disease or insects. These tomatoes have been most likely altered to have more lycopene, which can help prevent prostate cancer.
Involuntary inclination for a plant to respond to certain stimuli by growing in a certain direction. This cucumber plant is growing against the fence in order for it spread out and prevent the different stems from choking each other.
A powdery substance produced by the anthers of a plant that contains the male gametes (sex cells). This picture shows pollen from a flower still on the anthers.
An organism capable of making organic compounds (nutrients) using from simple inorganic substances and the light from the sun (photosynthesis) or inorganic chemical reactions (chemosynthesis). This plant uses photosynthesis to create it's own food.
An organism incapable of synthesizing its own food and feeds on organic matter that is produced by or found in other organisms. This clown fish is an example of a heterotroph.
A chemical reaction brought about by yeast or bacteria, usually converting carbohydrates in alcohols and carbon dioxide. This wine was created by fermenting grapes.
A relationship between two organisms in which one organism benefits and the other remains neutral. The bird benefits from this plant by creating it's nest in it, while the plant remains neutral.
A relationship between two organisms in which both organisms benefit. Lichen is an example in which algae produces food for the fungi through photosynthesis, and the fungi takes in water for the algae.
A relationship between two organisms in which one organism benefits and the other is harmed. This bug bite shows how a mosquito benefits by getting food, and the human gets harmed.
A dormant reproductive cell. It is thick walled to survive harsh conditions, and can grow into a new organism when suitable conditions arise. These seeds are spores because they can start to grow under their suitable conditions (water and soil.)
The ecological role of an organism in a ecosystem, usually in regards to food. This grass provides nutrition to herbivores such as deer, therefore filling in an ecological niche.
Involuntary inclination for a plant to respond to certain stimuli by turning in a certain direction.These flowers have turned to follow the sunlight, thus exhibiting taxis.
A biological interaction in which a predator (the hunter) eats its prey (the victim.)
This snake is a predator because it feeds on other small insects and rodents.
An organism that feeds on the waste of other organisms. This mushroom is an example of a detritivore.
The phase of a plants life cycle in which gametes (sex cells) are created. This flower has pollen, so it has already went through its gametophyte stage.
A characteristic that repels water. Hydrophobes are usually non-polar and prefer contact with other neutral materials. The water drop remain separated from this leaf, making the leaf hydrophobic.
A characteristic that makes a molecule attracted to water, and can also be dissolved in water. This salt can be dissolved in water, so it is hydrophilic.
An organism that takes pollen from the male anthers of a flower to the female stigma of a flower. This bee is an example of a pollinator because it transfers pollen from plant to plant.
The female reproductive part of a flower, the part of the pistil that contains the ovul. This picture shows a flower ovary.
A segmented body is divided into smaller segments that are usually grouped into a larger functional unit. This moth has an abdomen and a thorax, so it has a segmented body.
An external skeleton that protects an organism's body as well as supporting it and keeping the organism together. This ant has an exoskeleton to contain all of it's organs and give it shape.
12.) Auxin Producing Area of a Plant
Auxin is a hormone made by plants in areas where a new shoot or root is being grown. This stem is still growing, so auxin is present in this new shoot.
57.) K- Strategist
This organism has a lower mortality rate and bears less offspring, but has longer lifespan with a stable population size. Humans, like my sister, are considered k-strategists.
80.) R- Strategist
This organism has a higher mortality rate, lower lifespan, and an unstable fluctuation in regards to population, but bears lots of offspring. Most fish, such as this betta, are considered r-strategists.
All of the same species of an organism that live in a selected geographical area. Within my yard, there is an entire population of worms.
46.) Gymnosperm Cone
A gymnosperm is a seed that is not enclosed and protected by an ovary. This is a picture of a gymnosperm cone that came off an evergreen tree.
Gymnosperm plants produce no fruit, and also have different shaped leaves. This picture of an evergreen tree shows the needle-like shape instead of the usual broad, flat shape seen on other trees such as maples and oaks.
Tissue from which new cells are created, enabling the plant to grow. The root of this weed is an example of a meristem because it's a part of the plant that grows.
The most common type of cell in a plant used to store nutrients. They can also divide and create more parenchyma cells throughout their whole lives. Most of the flesh in a fruit, such as this apple, is composed of these cells.
Body parts that are alike in structure due to a common ancestor. They can, but don't have to, serve the same functions. A monkey arm and a human arm have a similar skeleton structure, making them homologous.
A horizontal underground stem which can create roots and shoots. This weed has a rhizome.
A type of tissue in a plant used to transport water and nutrients from the roots to the shoots and leaves. Also provides structural support. This plant stem is full of xylem cells.
93.) Vestigial Structures
Organs or body parts that no longer have a purpose or have greatly reduced functions from their original ancestral functions. This chicken (before it was killed and packaged) had wings that don't have much use left.
A spore-producing plant. This pepper that came off of a pepper plant produced spores (seeds), so it is a sporophyte.
Tissue lining that covers organs and other internal surfaces of the body. This gerbil has epithelial tissue lining its organs.
An organism whose cells contain a membrane-bound nucleus. This tree is full of eukaryotic cells.
A fungus whose spores develop within basidia. This mushroom is an example of a basidiomycete.
All bacteria besides archaebacteria. E-coli, which can be present in raw meat, is a type of eubacteria.
Unicellular microorganisms which are genetically distinct from eukaryotes and bacteria, usually inhabiting extreme environmental conditions. There are methane-producing archaebacteria (methogens) in this compost pile.
92.) Unicellular Organism
An organism that consists of only one cell. Sponges are considered unicellular organisms.
16.) Biological Magnification
The increasing concentration of a substance, such as a toxin or chemical, in the body of organisms at successively higher levels in a food chain. Fish higher up in the food chain usually suffer from this.
