Angiosperm: Angiosperms are most commonly referred to as flowering plants. They are the biggest group in the plant kingdom because they consist of all roots, stems, leaves, and flowers. They have an egg or ovule that is fertilized by [[Biology Collection Mackenzie Meixner#|pollen]] and makes the seeds to reproduce. Angiosperms includes many plants we encounter on a daily bases.

Pollen:
Pollen in a plant is a mass of microspores in a seed plant that appears as a fine dust. Pollen is contained in the anther of an angiosperm flower, male cone of a coniferous plant, or male cone of other seed plants. Pollen is extremely important to the reproduction system. When pollen lands on a compatible pistil of a flowering plant, it germinates and produces the male gametes, or sperm. The pollen tube then transfers the sperm to the ovule making germination possible.

stem-woody:
A woody stem in plants is important to the structure and make up of a plant. A woody stem thickens as the plant grows to accommodate the growth of a plant. It helps with the circulation of nutrients throughout the plant. The woody stem is made up of mostly lignin and cellulose.

deciduous leaf:
Leaves that lose their leaves once a year are called deciduous leaves. During winter and, or dry season it becomes too difficult for the plant to maintain the nutrients and water so the leaves drop off. The plant’s loss of their leaves allows them to survive better during the winter and dry seasons.

Conifer leaf:
Conifer leaves are needle- like, naked seeds of coniferous trees. Conifer leaves have a thick epidermis and cuticle and their stomata are sunken. Conifers are able to survive the harsh winters because of it’s coniferous leaf adaptations. Conifer leaves shed their leaves but do so over a long time span because it is more efficient for the plant to survive. Very important to a plant’s survival and reproduction.

Gymnosperm cone:
A gymnosperm cone comes from a gymnosperm plant which are referred to as conifers. The gymnosperm cone is the leaf of the conifer. They are found in needle forms, and often cone like groupings. They are referred to as naked seeds. The gymnosperm cone is important to conifer reproduct

Autotroph:
An autotroph is often referred to as a producer. It is an organism that produces complex organic compounds from simple inorganic molecules using photosynthesis, energy from light. They are able to make their own food and are the producers of the food chain. An autotroph converts physical energy from sun light into chemical energy in the form of reduced carbon.

Tendril of a plant:
A tendril is a coiling part of a plant that helps support the stem of some plants. It anchors and supports stems. Other special structures have similar functions, but the tendril is able to encircle and grow around any object. A tendril is important to the structure and growth of plants.

Thorn of a plant:
Thorns of plants are actually modified branches or stems. Thorns are important to plants because they protect the plant against herbivores. Thorns represent the modification of an axillary shoot system. Thorns have come about as an adaptation to being eaten by herbivores.

Stem- herbaceous:
Differing from the woody stem the herbaceous stem has little to no woody lignin making it up. They are often soft and green. A down side to herbaceous stems is the death of the plant every year during a cold or dry season. The plant relies on the stem to get it’s nutrients and water. Herbaceous stemmed plants are often annual. Cuticle layer of a plant:The cuticle layer of a plant is the non-cellular protective, outer layer that covers the epidermis, the outer cell layer. He cuticle is very crutial to the protection of plants. It protects the plant against UV radiation and various kinds of physical and chemical agents. It also provides the plant with some support. The cuticle of a plant is often compared to the skin of a human. Cellulose:Cellulose makes up around 33% of plants! It is the most common organic compound on Earth. It is an organic compound, a complex carbohydrate, that is found most importantly in plant’s cell walls. It is also important to strong branches, leaves, and stems. Ovary:An ovary is a part of the female reproductive organ of the flower specifically. It is located at the base of the connection point of the base and the petals. All types of ovaries are very important to the reproduction of plants. The ovary contains ovules which once fertilized become seeds which allows plants to reproduce. Frond:A frond is a fern-like foliage of a plant that has many divisions. They are large divided leaves that bear sporangia which allow them to reproduce. Many ferns and palms have fronds that arise from the stem and grow horizontal to the surface. Fronds of plants are important for identification of plants, and reproduction. Lignin:Lignin is a complex chemical compound derived from wood. It is an integral part of the secondary cell walls of plants. It is important for its strengthening of wood in trees. More specifically its strength in xylem cells because it fills in the spaces of the cell wall between the cellulose. It is also hydrophobic and it is impermeable to water. Phloem:Phloem is the living tissue in plant that conduct and carry organic nutrients to all the parts of the plant. The phloem transports materials such as glucose and water that is made during photosynthesis. With out the phloem the plant would not be able to get the nutrients it needs to survive and flourish. Xylem:Xylem is the other transport tissue located in a plant. Xylem is more important in transporting water throughout the plant rather than nutrients like the phloem. Xylems take the water derived from the roots of the plant and transport it through out the plant allowing the plant to be nourished and survive. One way a plant gets it’s water. Syle and Stigma of Carpel: The style and stigma of carpel refers to the make up of the plant. The carpel is made up of the ovary, which is the style, and stigma which is in the center of the flower. Carpels are leaves that have evolved to enclose the ovules of the plant. Style and stigma are important to the reproduction cycle of plants. Short day plants:A short day plant is described as a plant that only flowers after being exposed to light periods but the night is longer than that light period. They require a consolidated period of darkness before floral development can begin. Short day plants flower as days grow shorter. Short day plants have formed as an adaptation to the long hot days in which the plant lost a lot of it's water during flowering. Long day plants:A long-day plant requires fewer than a certain number of hours of darkness in each twenty-four hour period to induce flowering. In contrast to short day plants long day plants flower as the days become longer.These plants require a long amount of time of exposure to light in order to produce flowers. Plant have adapted to this schedule do to it's development during the right amount of sunlight and temperature.
