Plants are amazing, complex organisms that provide the very air that we breathe. Without plants, there would be no planet Earth. In this quiz, we're going to test your knowledge about the very basics of the plant kingdom. Put on your gardening clogs.
If you didn't get this first question right, you've got a long road ahead of you. Plants make their own food through a process called photosynthesis!
There are some carnivorous plants! The most famous bug-eating plant is the Venus flytrap.
Plants use sunlight to create food. Photo means light, and synthesis is just what you think it means!
Chlorophyll is the chemical in the leaves of a plant that makes them look green. Chlorophyll soaks up the energy and light from the sun.
Water is pulled through the plant's roots through cells called xylem. The water then makes the journey up to the plant leaves.
Plants breathe, sort of, but not in the same way we do. While we breathe oxygen and emit carbon dioxide, plants breathe carbon dioxide and emit oxygen!
Plants come in a variety of types. Some have flowers, some have fruits, some have vegetables, and some are quite poisonous.
Plants have tiny holes in their leaves called stomata. The stomata are where the plants take in carbon dioxide. A single hole is called a stoma.
Once a plant collects enough water and carbon dioxide, the light of the sun converts these into glucose. That's plant food!
Plants will use the hydrogen molecules from water in order to prevent them from getting dry and wilting. The human body has a similar process.
The cell walls of a plant have two main functions. These include surrounding the actual cells of the plant and keeping it sturdy and also protecting the individual cells.
After glucose is made through photosynthesis, there's always something left over. This is oxygen, and since the plants don't need it, they release it into the air.
Plants release oxygen through a process called respiration. Oxygen is released from everywhere - their leaves, stems, flowers, and even roots.
Did you know that photosynthesis is the most important chemical process in the world? We wouldn't be here without it!
The leaves of the plant have the most work to do. They're also the most important part of the plant.
Plants come from seeds that are planted in the soil. These seeds will then begin to sprout.
For seeds in the soil to sprout, they must go through a process called germination. Germination takes place within the seed itself.
The outside of a seed is called a seed coat. This is a layer that you can feel with your hands before you plant the seed in the ground.
Not all seeds have a hard seed coat. Some, such as tomatoes, cucumbers, peppers and marigolds, have a soft coat.
These are the four main parts of the inside of a seed. These include the parts that will become the leaves, stem and roots.
The seed coat has tiny pores, called micropyles, that take in oxygen and minerals from the soil, as well as water. The seed needs these in order to break open.
Once the seed is filled with food, it literally pops open! That's how we can feel sometimes when we have a big meal. LOL
The roots are the first bit of the plant to emerge from the seed. The roots start as the radicle inside of the seed.
Seeds come in an amazing variety of colors and sizes. Did you know that corn kernels and peas contain seeds, and that rice is a seed? It's true.
Since all seeds are so different, they all germinate at different speeds. Hard coated seeds germinate faster than soft coated seeds.
Seeds often remain dormant during the fall and winter seasons. The soil is too cold for them to germinate.
What all plants share in common is that they produce oxygen. This is because all plants must undergo photosynthesis in order to eat.
The roots grow just as much as the visible parts of the plant grow. This is to keep the plant stable, and also to obtain more water and nutrients from the soil.
Buds are the first things that you see growing on the stem of a plant. These little buds on the stem will then grow into petioles.
Once a plant has matured, it will start to flower, if it's a flowering plant. On some plants, these flowers will turn into fruits or vegetables.
Did you know that a pineapple is actually a cluster of berries? Well, it's true. That's a pretty funny looking berry, though.
Avocado is a protein-rich fruit, containing 18 important types of protein. They're also high in potassium and healthy fats, and can sometimes be substituted for butter in baked goods!
There has been no discovered plant that produces black flowers or blossoms. None has been artificially developed either. Some blooms are quite dark, but there's always at least a touch of purple or magenta.
Tree resin that has fossilized is called amber. Sometimes little bits of plants or insects will get trapped in it. Are you thinking about "Jurassic Park" now?
Humans enjoy just about 2,000 different types of plants as food. Plants benefit from being eaten because those creatures - including humans - help spread their seeds.
