Monocot Or Dicot?


This is a root of a plant and it is from a dicot, because the vascular bundles are in a ring shape. This indicates that the plant is a dicot.


This is a leaf of a plant and it is from a monocot plant because a monocot has leaves with parallel veins, or vascular bundles. These vascular bundles are nice and straight, so it is a monocot.


This is a stem of a plant and it is from a dicot because the vascular bundles are, again, in the shape of a ring.

Skunk Cabbage Plant


This is a Skunk Cabbage plant. The reason it has this name is pretty simple, it gives off a foul odor, often mistaken for the odor of a skunk. The weird thing is that it uses this smell to attract bugs. I think that is pretty cool because I've heard of bugs being attracted to plants because of color, but not by smell! Another weird fact, stated near the end of the video, is that this plant can be used for cooking! How can a skunk-like smelling plant be used to make food? For more information, watch the video shown above.

Extreme Plant

This scary-looking plant is called the Hydnora Africana. It looks a lot like a venus fly-trap plant, but even worse! This plant smells like dung because one of its favorite visitors is the dung beetle. Eventually the dung beetle crawls into this plant's jaw-like leaves, and then, rather than eat the beetle, it instead traps the beetle alive for a short period of time. The Hydnora Africana's goal is for the beetle to lose bodily fluids so the fluids can pollinate it. After being pollinated the plant opens its mouth, letting the beetle go.

Pinecones and Acorns


The main difference between pinecones and acorns is that pinecones have seeds and acorns do not. Pinecones come from coniferous pine trees (coniferous meaning cone bearing) and acorns come from deciduous oak trees. Acorns are dispersed because of all the animals that eat them. Either they are eaten and later expelled from the animal when it goes to toilet, after which they grow, or when squirrels bury their acorns they often forget one or two, so then the acorns grow there. Pinecones disperse themselves by dispersing their seeds (pollen) using the wind. One thing similar between pinecones and acorns is that they both grow on trees.

Plant Parts Under A Microscope


This is a general cross section of a root of a vascular plant, shown under a microscope on medium power (100x). The major functions of roots are to absorb water and nutrients, anchor the plant body to the ground, and store food and nutrients. The xylem and phloem, tube-like structures, help the roots to distribute the water and nutrients throughout the plant, and to all the cells high above ground.


This is a general cross section of a stem of a vascular plant, shown under a microscope on low power (40x). The major functions of stems is to provide support for the plant, and stems also connect the leaves to the roots so that the water and nutrients can be transported from the roots, through the stem, and into the leaves. Woody and herbaceous stems are different because woody stems are hard, and they grow taller and bigger. Some plants with woody stems are shrubs and your average tree. Herbaceous stems are much softer and plants with these stems are usually short and small. This is because these stems don't grow additional tissues, like woody stems. Plants with herbaceous stems consist of herbs, crops, broccoli, generally your basic backyard garden plants.


This is a general cross section of a leaf of a vascular plant, shown under a microscope on high power (400x). The major functions of leaves are to obtain gas exchange, and sunlight for photosynthesis. Also, they help the plant to respire, and they store food material. The chemical reaction for photosynthesis occurs when the plant obtains carbon dioxide, water, and light. Using these things the plant produces oxygen, sugar, and water. Stomata are important to plants because plants mainly lose their water through these spaces, which allows transpiration. Also, stomata let carbon dioxide through for photosynthesis, which is why stomata are important to us too, because since they let carbon dioxide through, photosynthesis occurs, which means we get more oxygen.
