Definitions: Tendril of a plant- a specialized stem or leaf that has a threadlike shape. It is used by climbing plants for support and attachment. They can twine themselves around items to help the plant. Without these climbing plants would not be able to climb and wouldn’t exist. Autotroph- An autotroph is an organism that can make its own food from an inorganic source of carbon with a source of energy. Most autotrophs use photosynthesis to make their own food. Autotrophs are essential to life on Earth. They make all of the consumable energy for other organisms. If we didn’t have them we would have no way of obtaining energy. Without them we would not be able to exist. Cellulose- The structural component in plant cell walls. It’s the most common organic compound on earth. Cellulose helps plants in osmosis and digestion and mainly helps with the structure of the plant and to keep is strong. Cellulose is very important to plants to keep the structure of the plant and without it the plant would not be able to function properly. Endosperm- This is tissue produced inside the seeds of most flowering plants right around the time of fertilization. It helps the embryo by surrounding it and providing it with nutrition in the form of starch. The initiation of endosperm is a definitive characteristic of angiosperms and requires the fusion of at least one nucleus in the embryo sac with a sperm nucleus from the pollen grain. In some plants the embryo absorbs all of the embryo by maturity and in other plants it is present till germination. Endosperms are important to the development of the embryo to provide nourishment. Endosperms are also very important to humans and their diet. Ethylene- a plant hormone that is a gas. When fruits near maturity many of them release this gas to help promote the ripening of the fruit. This is important so fruits can ripen themselves when they are supposed to. Ethylene can also cause a plant to have drooping leaves, have flower formation, and seed germination. Lignin- Complex chemical compound that is found in the secondary cell walls of plants. One the most abundant organic polymers on Earth. It is most commonly derived from wood. It is crucial to help support and strengthen. Phloem- Living tissue found in plants that carries organic nutrients, mainly glucose, to areas of the plant where it is needed, which is called translocation. Without the phloem plants could not survive and there would be no life. Phloems are needed to make sure the plant has all the nutrients it needs in the right places. Short Day Plant-These are plants that only flower after they have been exposed to sunlight in shorter times than a certain critical length. This would be in spring or fall. They time their blooms to the amount of sunlight that they receive. These types of plants can be used by humans to bloom in the winter or times when they usually do not by exposing them to the rights amount of light and tricking them. Long day Plant- These are the opposite of short day plants and only flower when they have been exposed to light in longer period that the certain critical length. Examples are spinach, lettuce, and some varieties of wheat. Xylem- another type of transport tissue with phloem being the other. The xylem helps to transport water around a plant. The xylem can also help with the storage of food. Xylems are very important to life and without them plants couldn’t function because they need water. Xylems use osmosis to transport the water.
Pictures: Angiosperm- These are seed producing plants. They are different from gymnosperms because they have flowers, endosperm with seeds, and the production of fruit with the seeds. These are important because humans use these a lot for food and many other organisms depend on these.
Cuticle layer of a plant-a top waxy layer on a plant that helps prevent water from leaving the plant to keep the plant from being dehydrated. It is non-cellular and protects the outer cell layer. These are important to keep the cell hydrated and without them many plants would not be able to survive extrememly hot days.
Fruit(dry with seed)-dry fruit happens when the seeds age and the tissues of the fruit dry out. Dry fruit can be divided into two different categories. The first category is Dehiscent, this is where the seeds are contained in a seedpod which opens to release the seeds. The other category is Indehiscent, which is the opposite in which there is no seed pod that opens. Dry fruits are an important source of foods to humans because they are plentiful and easy to get.
Fruit(Fleshy with seed)- these fruits can either have one seed or many seeds and can be divided into ones that form a single flower and those who form a group of flowers. Some examples of these are strawberrys, tomatoes, and watermelons. These are important because they are a very important source of food and are needed to maintain a healthy diet to all organisms.
Gymnosperm cone- these are seeds from gymnosperm plants that are not enclosed in any specialized type of chamber. The male cone is the one that produces pollen and the female cone contains ovules that when fertilized by the male’s pollen become seeds. These are important to the survival of the specifies and the diversity on Earth. Monocot plant with flower and leaf- in these plants, when the seed germinates, one leaf emerges instead of two, which happens in dicots. They have parallel venation in the leaves, a fribrous root system and flower in all parts in multiples of three. They are important because they provide the Earth with diversity and are important to ecosystems. Pollen- a fine, coarse powder that is produced into the male gametes. They have a hard coat that protects them during they’re movement. When the pollen does land on the pistil of a flowering plant it germinates and produces a pollen tube that transfers the sperm to the ovule of a receptive ovary. It is produced by the anthers of plants. They are important to the development of plants and without it there would not be many plants which would result in less diversity and life on Earth.
Stem(herbaceous)- stems of plants that have little or no woody tissue. They have modified themselves to serve the same function as leaves. In colder climates the stems die back. Without herbaceous stems we could not have flowers and other things on Earth that help diversity and beauty.
Stem(woody)- These are hard woody stems. They have been growing for two years or more. After the two years the stems thicken to accommodate for growth and increased circulation in a plant. The most common example of this is tree trunks. These stems are very important becuase without them we could not have trees which attribute the oxygen. Thorn of a plant- thorns are tiny spikes found on some plants that help protect the plant from herbivores. They are modifications on the branch of a plant. These are important to plants to help protect it and keep it alive.
