1: Autotroph | Autotroph are organisms that can produce their own food all the way from carbohydrates to proteins. Autotroph, just simply mean "self-feeder". This is a picture of a plant which is the most common autotroph.
2: Keratin is a fibrous protein mainly found in hair, nails etc... Keratin is essential for strengthening and toughening the outer layer of the body. This is a picture of hair, showing how keratin promotes hair growth. | Keratin
3: Epithelial tissue is made up of cells that are closely packed together. Its main function is to cover internal and external body surfaces. This is a picture of skin and how it is an example of epithelial tissue. | Epithelial Tissue
4: This is a picture of an Angiosperm which is basically a flowering plant that produces seeds. | Angiosperm
5: f | s | Spores are reproductive cells produce by fungi or other plant organisms, sometimes as a defensive mechanism. Spores grow best in moist areas around plants such as in this picture below. | Spores
6: Thorns are sharp things located on stems of plants, not just roses . Plants use those thorns as a way of defense against other organisms. As seen in this picture below, thorns have sharp, and pointed ends. | Thorn of a Plant
7: This picture shows an example of a fruit-fleshy with seeds. These kind of fruits have a fleshy, soft surface between the the skin of the fruit and the seeds, like that apple above. The sweet and edible raw state separate the fruit's covering with the seeds in the center. | Fruit-fleshy with seed
8: Insects are a class of living creatures within the arthropods who share similar body characteristics; an exoskeleton, a three part body, three pairs of joined legs and a air of antennas. Up above is a picture of an American oil beetle on a leaf ; a type of insect. | Insect
9: This is a picture of the cuticle of a plant. The cuticle is the outer layer or covering of an organism that provides a tough and flexible layer. | Cuticle
10: Herbaceous stems are upper stems of plants that provide structure for leaves at the top of the stem. Although they are much weaker than woody stems, they are able to undergo photosynthesis. | Stem-Herbaceous
11: This is a picture of a tendril. Tendrils on a plant are specialized stems with a threadlike shape that climbing plants use for support. They coil and wrap themselves on walls or other plants. | Tendril of a plant
12: A niche is the position or role an organism plays in its surrounding habitat. This is a picture of a spider on a spiderweb on bbq grill ; this describes how the spider traps insects into its web for food. | Niche
13: Woody stems as their name implies are made up of wood and covered by bark. They are way bigger and stronger than herbaceous stems and have little openings for respiration. This is a picture of a woody stem. | Stem-woody
14: A eukaryote is an organism whose cells contain structures enclosed in a cell membrane, and every mammals including us humans are examples of that. Below is a picture of a human, who is made up of billions of eukaryote cells. | Eukaryote
15: Phloem are soft wall tubes in the stems that carry organic nutrients of the plant back down in the roots to store it. In the picture above, phloem is located inside the stem. | Xylem are hard wall cells that carry the water and mineral nutrients from the roots up to the plants. It does the opposite job of the phloem. Xylem in this picture is located inside the stem.
16: q | Female pine cones are a little bigger than male cones and carry ovules for reproduction. During fertilization, the female cone opens up to allow the pollen to enter, and then closes for reproduction. It is responsible for producing seeds.
17: Flower ovary is the female reproductive organ in the flower. At an early stage it is enclosed and looks like a little tiny ball and it later develops to a flower. The ovary in the picture above is the brown, round little balls. | Every organism adapts in its own way that best suits it to survive. The picture below shows how a plant, cactus, adapts to its environment by retaining water in its long leaves and using thorns to prevent itself from predators.
18: A gymnosperm cone | A gymnosperm cone or male cone produces pollen to fertilize the female cone. They normally grow on the lower part of the conifer tree compared to female cones and are usually smaller than female cones. This is a picture of a mature gymnosperm cone. | Gymnosperm Cone
19: Fishes are the most common two chambered heart animals . They have one atrium and one ventricle that pump the blood throughout their body. The picture above shows scales from a fish. | Basidiomycete are members of a large group of fungi that produce spores sexually. They play a significant role in the carbon cycle. Below is a picture of a mushroom, which is a type of basidiomycete.
20: C4 plants are plants that carry on photosynthesis by adding a supplementary dose of carbon dioxide. These plants mostly grow in habitats of high daytime temperatures and intense sunlight. This is a picture of corn (also known as maize) one of the few C4 plant. | C4 Plant
21: Below is a picture of yeast. Yeast is used in both bread and alcohol fermentation. It converts natural sugars into alcohol and releases carbon dioxide in the process, giving that rise on the bread. | Fermentation
22: Rhizome are horizontal plant stem capable of producing the shoot and root of a plant. In this picture, we can see how the rhizome are intertwining with other rhizome acting like roots, but are horizontal. | Rhizome
23: Frond is a large divided leaf with evenly divided. (especially a palm or fern leaf). Above is a picture of a leaf of a fern, often referred to a frond. | Fruit- with dry seed are fruits with seedpods and can be opened to expose the seeds like in peanuts or do not expose their seeds. This green bean below is an example of a fruit with dry seeds. you have to open the green bean in order to see the seeds inside.
24: Fibrous carbohydrates are carbs full or minerals, fibers and vitamins. They typically tend to be green vegetables and take longer for the body to digest due to their high content of fiber. This is a picture of a broccoli which is a fibrous carbohydrate. | Carbohydrate-fibrous
25: Leaves that fall off a tree once a year are known as deciduous leaves. The word deciduous just means "falling off at maturity", so once the leaves are mature, they fall off. Above is a picture of a deciduous leaf. | Deciduous Leaf
26: Connective Tissue | Connective tissue is the most abundant tissue in the body. It covers the surface of most internal organs and has less cells than most epithelial tissues. This is a picture of a cow's stomach (part of it). You can see the surface and how its in a form of a matrix. The lining of the stomach is made up of connective tissue.
27: Glycogen | Glycogen is a polysaccharide that is primarily stored in the liver and muscles and used for energy. It is a form of carbohydrate and is later turned into the body from consuming foods high in starches such as bread (in the picture below).
28: Lipid used for energy storage | Lipid is a fatty or organic compound that is stored readily in an organism or non polar solution . Fats such as this piece of white fat in this meat(chicken) is used for energy storage in the animal.
29: Dicot plant with flower and leaf | A dicot plant is a plant whose leaves branch out and they typically have four to five flower petals. Below is a picture of a dicot plant with flower and leaf; look at how the leaves branch out and don't run parallel like in a monocot plant.
30: Myosin works with the other protein actin to aid in muscle contraction, relaxation and other muscle movements. Myosin is also found in filaments inside the relaxing muscle in the picture above. | Actin is a protein that functions in the contractile system of the skeletal muscle. Actin in the picture below, is found in thin filaments inside the flexed muscle.
31: Protein- fibrous | Fibrous proteins are usually inert structural or storage protein. They are used to construct connective tissue, tendons, bones and muscle fibers. Hair , as shown in the picture above, is made up of keratin which is an example of a fibrous protein.
32: Arthropods are the largest animal group on Earth. They are animals with segmented bodies and six or more jointed legs. This is a picture of an insect on a leaf, a type of arthropod. | Monocot plants are one of the two major flowering plants. They are characterized by having veins of the leaves that run parallel and flowers that part in three, not four like in dicot plants. Look at the picture of the corn leaf below, the veins run parallel.
33: Leaf-gymnosperm | A gymnosperm is a plant that has seeds unprotected by a fruit or an ovary. They include conifers, cycads and ginkgo. The leaves of this plant are needle-shaped and the tree produces cones making it a gymnosperm leaf.
34: Cellulose | Cellulose is a long chain of sugar molecules that is found in the rigid cell walls of plants . It helps give wood its remarkable strength. Cellulose is found in the cell wall of the plant stem above.
