1 Plants and Plant Organs By Adriaan Berger

2 What are all the plant organs? One of the main plant organs is the stem. It holds the plant upright. It kind of acts like the skeletal system in a animals body. It also acts like the circulatory system getting ingredients for photosynthesis around the plant. Another main organ is the roots. They suck minerals, nutrients and water to the to be transported to the leaves. It also hooks the plant onto the ground so that the winds dont rip it out. The main organ of a plant that acts as a kitchen are the leaves. This is where photosynthesis happens. All the nutrients that got transported from the roots go here. It also collects CO2 from the air. After all that happens, O2 is released in the air. They also collect sunlight. The last main organ is the flower. Its the plants main reproduction system. If the plant doesnt have flowers then it uses fruits or vegetables. If it doesnt have any it just launches the seed away in some way. It reproduces by have bees, bats, the wind, birds or other insects pollinate the flower. Then the grain of pollen takes a journey towards the flowers ovule. There a seed grows like a baby in a mothers womb.

3 What are the Smaller jobs of the Leaves? Well, there millions of different types of leaves and you might just think, oh, heres a leaf, it cleans our air, bye leaf! Thats not all it does it also takes CO2 from the air, turns it into glucose and O2. After that it releases the O2 into the air because it doesnt need it. It also collects sunlight, or, light but sunlight is the most powerful. Thats why leaves are always high up in a tree. Also because CO2 lifts up in the air when it leaves a cigar/cigarette, factory, bonfire, your mouth/nose, or any other objects that create CO2. Leaves are mostly thin and flat, thats because it increases the surface area that absorbs sunlight and CO2, like the plant root cell! If the leaf has any nutrients left from creating sugar with photosynthesis, it stores it for the next time. You see how leaves are a Lot like skin?

4 Smaller Jobs of the roots These pipes are located at the bottom of a plant and they are the thin/large strings that hang from the plant when you take one out of the ground. There are lots of types of roots like the fine roots, stilt roots, aerial roots, structural roots but Im not going through all of them. I think of roots as just three types: Structural, Storage and Fine. The Structural roots hold the plant in the ground so that it doesnt blow away. Its mostly very thick. The storage roots store water, minerals, and nutrients, as you may have imagined. The fine roots take the water, minerals and the nutrients up towards the stem of a plant. looks like a nerve net doesnt it?

5 Smaller Jobs Of The Flower The flowers are mainly used for reproduction, but how does this happen? First a bee or the wind or a bat or bird is attracted to the sweet smell of nectar and pollen inside the flower. So they fly towards the flower and take as many pollen grains as they can but leave one behind inside the flowers pistil, which then starts the big journey to the flowers ovule where it grows and becomes a seed. But if the animal or insect cant smell the nectar inside the flower, theyre still attracted to the beautiful form of the flower, except if the flower smells really bad like the Rafflesia flower. Rotten meat! UGH!!!

6 Smaller Jobs of the Stem The main jobs of the stem are holding the plant upright and transporting water, minerals and nutrients through the plant. The stem is thought of as mainly made up of three tissues- the dermal tissue, the ground tissue and the vascular tissue. The stem has a extremely large job but I cant say much about it.

7 That Was It!!! Thank You for watching and if you have any comments or questions, send them to either or
