Hello everyone welcome to my blog today, I’ll be writing about plant as part of science and it’s historical development and it’s economic importance. Thanks for reading through this post as I assure you it’s going to be an interesting topic.

WHAT ARE PLANTS

plant have multiple of cells and they are characterized by chloroplast that enable plant to carry out photosynthesis in which chemical energy is produced from water, carbon dioxide with the help of the green pigment known as chlorophyll and the radiant energy from the sun.

In the above definition about what plant are their are key words use which are photosynthesis, and chlorophyii

Photosynthesis is a process that occurs only in green plant. In these process plant cells will use the energy from sun to produce sugar from carbon dioxide and water. It is represented in simple equation below.

Energy + water + CO2 = sugar and O2.

It is said that photosynthesis is the most important chemical reaction on earth. It

^{how chlorophyll looks like inside a chloroplast}

Chlorophyll is a green pigment it’s found in all green plant located inside the chloroplast it’s main function is to trap light from the sun to provide energy so plant can carry out photosynthesis easily.

Plant are in the kingdom called plantae and they are multicellular eukaryotic organism that means they have plenty cells and also in localized region plant have unlimited growth. Also their is a cellulose cell in plant that makes their cell wall strong.

Qualities of plant

• plant lack organ for location ( means they don’t have the organ that can make them move from place to another)

• no nervous system

• plant goes through alternation of generation. These generation are sporophyte and gametophyte generation

---

sporophyte

these are plants that have leaves, steam, roots, and branches any plant you see with is features the plant is undergoing a sporophyte generation. While the gametophytes is when plant beings flower and fruits.

---

Also their are basically two groups of plant which are vascular and non vascular. The vascular plant do not posses vascular bundles which are the xylem (which conduct water)and phloem ( translocate food). Eg are the pteridophyte, spermatophyte etc.. Them the non vascular plant does not have true roots, stem, and leaves example are the algae’s, mosses, liverworts etc.

PLANT BODY PLAN

plant is so special it’s it’s body plan is so simple for anyone to understand the body is divided into two which are the underground system and the above system. The underground system is made up of the root and the above system is made up of stem, branches and leaves. The root is responsible in absorbing of water from the soil and also help plant to store food like the cassava, yam, carrots, potatoes etc. their food are stored in the roots. The stem and branches connect root and leaves to each other they are said to be high ways as water, nutrients and sugar travel through to freshen or nourish the various parts of the plant.

In plant the leaves are the most important because that were photosynthesis occur also the leaves is responsible in producing much energy to feed the whole plants.

ECONOMIC IMPORTANCE OF PLANT

• oxygen : during the the photosynthesis process plant release oxygen we humans need it for respiratory process why the take the carbon dioxide. If their Was no plant to take out all the carbon dioxide been polluted by humans the earth would have been so polluted with carbons and these will make life uncomfortable for we humans.

• nutrition: plant is the primary produces so as a result of this all the food we eat comes from plant like the yam, beans, rice, nuts, etc..

• ornamental : plant are used to beautify an environment

• for medicine : most drugs produced are gotten from plants.

---

Lot of materials from plant can be used to get so manny things for human shelter like clothing, biofuel ,furnitures, gums , soap, paints, cosmetics, lubricant, plastics etc.. which can be sold to get money too.

---

In conclusion

is very important in our today world as the remove carbon dioxide and provide us with oxygen with human and animals need for respiration also as a source of food to both man and animals because animal feeds on plant to grow while humans feed on both plant and animal. Cutting down of trees that is deforestation should be discouraged instead afforestation should be encouraged.

Thanks so much for reading this pice of epistle which I believe you gained some knowledge about plant.
