Howhumans use plants and plant products

Plantsand their products are essential in our daily lives as they provideus with many benefits ranging from essential nutrients for our bodiesto leisure and other environmental benefits such as rain formationand temperature regulations. In my day to day activities, I comeacross plants and plant products that are of great importance to me.

Mostof my meals comprise of plants and plant products. For example, mybreakfast consists of bread and coffee. Notably, bread is baked fromwheat, which is a cereal grain classified as angiosperm. Also, coffeeis classified as angiosperm and has distinctive characteristics suchas its female reproductive parts are smaller therefore, allowingthem to produce seeds more quickly(Cseke et al. 2016). Moreover,when coffee seeds are developing, they are usually enclosed incarpels, hence exhibiting a characteristic unique to angiosperms.

Besidesusing plants for food, I use plant products in my clothing, forexample, my cotton shirt that is manufactured from the cotton plant,which is classified as a vascular seed plant. Remarkably, vascularseed plants have thick cell walls to help in supporting the plantvertically(Wiersema, &amp Leon, 2016).&nbspAdditionally, they use the seed for their reproduction and theirvascular tissues. Another plant product that is used to make clothesis linen which is obtained from the flax plant which is also avascular seed plant.

Also,my furniture including chairs, bed, and the table at home are wooden.The timber used to make this furniture is obtained from trees.

Additionally,my landscape garden has many plants, including the Lycopodiums whichare vascular seedless plants(Cseke et al. 2016).Notably, Lycopodiums is not only used to beautify homes, but alsoserve some medical purposes as relieving of muscle pains. Thesevascular seedless plants have some distinctive characteristics. Forinstance, their photosynthesis process occurs in their stems.Additionally, they grow big and can grow to form forests.Particularly, vascular seedless plants are important, especiallyduring pollination as they move from one point to another and developto shelter other species(Wiersema &amp Leon, 2016).

Partsof the plants that are consumed

Notably,humans consume various parts of plants, including stems, fruits,leaves, roots, and flowers depending on the classification of thefood product of plants. Below are some photos to indicate thedifferent classification of food products in plants.

Figure1: Red onion

Humansconsume onions in various ways ranging from salad to frying them. Inmost cases, they are used when preparing soup as well as roasting.Particularly, all parts of the red onion are edible, and it isclassified as a root tuber. Notably, a root tuber is a plant whosenutrients are stored in the roots. Their classification owes to thefact that people consider it as a root vegetable whereby its roots isthe part that is eaten. Moreover, its food storage characteristic hasresulted in its classification as root tuber, as its nutrients arestored in the soils before it is harvested.

Fig2: Tomatoes

Theabove picture shows tomatoes that are mostly classified as fruitvegetables, and they are obtained from tomato plants. In most cases,the fruits are the only part that is eaten hence its classificationas fruit vegetables. Remarkably, tomato plants grow and store theirnutrients in the fruits. These fruits are known to be a source ofvitamins K and C.

Inconclusion, plants are used by humans in their day to day lives.Notably, plants satisfy basic human needs, including food, shelter,and clothing, and therefore, should be taken good care of.

Fossilevidence

Fossilrecords provide proof of past occurrences. When these elements arejoined, they show a part of evolution that took place a billion yearsago. Although some artifacts have mission elements, a closeobservation shows that they do not have some features that today’screatures have or such features are more enhanced (Ohno, 2013). Forinstance, researchers found the bite of a mosasaur on an ammonitefossil. Notably, the bites had marks that are entirely different fromthose of the current mosasaur, indicating that some level ofevolution took place. A cross-section of an artifact of a duckbilldinosaur Miaiasaura shows that it had a horizontal line. Such afeature could be an indication that it had periodic growth as aresult of evolution.

Anatomicalevidence

Theanatomical evidence is also significant in showing the process ofevolution took place. There is an anatomical similarity betweendifferent organisms although they do not have the same lifestyles.For instance, although dolphins share the same environment with fish,their semblance is quite superficial as they share many features withplacenta mammals such as lungs (Dobzhansky, 2013). Also, young onesof dolphins are gestated internally.

Anotherfeature that exhibits anatomical evidence is the tetrapod limbs thatare shared by many classes of animals such as mammals, amphibians,reptiles, and birds. Notably, this feature shows that livingorganisms share the same origin only that some form of evolution madesome to develop different features from others.
