How Much Do You Know About the Basics of Plant Biology?


Plants get their food through what process?

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!

Can plants be carnivores?

There are some carnivorous plants! The most famous bug-eating plant is the Venus flytrap.

Plants convert what into food?

Plants use sunlight to create food. Photo means light, and synthesis is just what you think it means!

What makes plant leaves green?

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 from the plant's roots travels up to _______.

Water is pulled through the plant's roots through cells called xylem. The water then makes the journey up to the plant leaves.

Do plants breathe?

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!

Do all plants have flowers?

Plants come in a variety of types. Some have flowers, some have fruits, some have vegetables, and some are quite poisonous.

Plants take in carbon dioxide through their ______ ?

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.

Energy from the sun helps a plant turn water and carbon dioxide into what?

Once a plant collects enough water and carbon dioxide, the light of the sun converts these into glucose. That's plant food!

Plants use _____ molecules to keep them from wilting.

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.

What do cell walls do?

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.

What is left over after photosynthesis?

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 from where?

Plants release oxygen through a process called respiration. Oxygen is released from everywhere - their leaves, stems, flowers, and even roots.

Photosynthesis is _______.

Did you know that photosynthesis is the most important chemical process in the world? We wouldn't be here without it!

What is the busiest part of the plant?

The leaves of the plant have the most work to do. They're also the most important part of the plant.

Plants come from where?

Plants come from seeds that are planted in the soil. These seeds will then begin to sprout.

Before a seed can sprout, what process must it go through?

For seeds in the soil to sprout, they must go through a process called germination. Germination takes place within the seed itself.

What do you call the outside of a seed?

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.

Are all seeds hard on the outside?

Not all seeds have a hard seed coat. Some, such as tomatoes, cucumbers, peppers and marigolds, have a soft coat.

Where do you find the epicotyl, hypocotyl, Radicle, and cotyledon?

These are the four main parts of the inside of a seed. These include the parts that will become the leaves, stem and roots.

How does the seed take in oxygen and minerals from the soil?

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.

When the seed is filled with food, it does what?

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

What is the first part of the plant to emerge from the seed?

The roots are the first bit of the plant to emerge from the seed. The roots start as the radicle inside of the seed.

Do all seeds look alike?

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.

Do all seeds germinate at the same speed?

Since all seeds are so different, they all germinate at different speeds. Hard coated seeds germinate faster than soft coated seeds.

When a seed sleeps, it is ______.

Seeds often remain dormant during the fall and winter seasons. The soil is too cold for them to germinate.

Do all plants produce oxygen?

What all plants share in common is that they produce oxygen. This is because all plants must undergo photosynthesis in order to eat.

As the stem of the plant grows, the root does what?

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.

What are the first things to grow on the stems of a plant?

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.

Flowers appear after a plant has ______.

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.

What is a pineapple?

Did you know that a pineapple is actually a cluster of berries? Well, it's true. That's a pretty funny looking berry, though.

What is one of the most protein-rich fruits on the planet?

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!

Are there black blossoms?

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.

What do we call tree resin that has fossilized?

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?

Roughly how many plants do humans use for food?

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.
