What Are the Different Parts of a Plant?

Word of the Week


Photosynthesis

Photosynthesis is the process used by plants and algae to change water, carbon dioxide, and sunlight into food (energy) for the plant and oxygen.


Very few plants need to eat like animals do. Most just needs water, fresh air (which contains carbon dioxide), and sunlight to grow big and strong!

Venus Flytrap

Dionaea muscipula

We just learned that most plants have the same basic parts. Though they may look different from one another, most plants have roots, stems, leaves, flowers, and fruits. Usually, leaves are responsible for changing energy from the sun into energy for the plant in a process known as photosynthesis. The Venus flytrap, however, does things a little bit differently. Instead of photosynthesizing, their leaves are responsible for catching small bugs and eating them - yes, eating them!


The Venus flytrap is a carnivorous plant found in a small part of the eastern United States. While parts of the Venus flytrap can photosynthesize for energy, they get most of the energy and nutrients they need from eating insects, spiders, and other small animals. Venus flytrap leaves are shaped like claws and produce a sweet smell that attracts bugs looking to feed on fruit or nectar. When bugs come to investigate the smell, they bump small, hair-like structures inside the leaf that causes it to snap shut like a trap! Once caught, the Venus flytrap produces digestive material that breaks down the insect just like our stomachs do when we eat. It can take up to 10 days to fully digest their food and, once digestion is complete, the trap reopens and waits for another unsuspecting victim. 

BRAIN BLAST

Venus flytraps are not the only carnivorous plant! Identify at least one other species of carnivorous plant and compare it to the Venus flytrap. Do they eat the same food? How does the other plant attract bugs? Does it also create a "trap?"

Plants In a Changing World

Like animals, plants are specifically designed for the conditions in their environment. This is why we don't see palm trees growing in the tundra or cacti growing in the rainforest. However, as the climate around the world changes, plants are at a real disadvantage. They cannot move to a more suitable climate and they can only adapt so quickly. 


Some regions are beginning to experience long droughts, which means there is less water for roots to absorb and stems and leaves don't have as much water to store. With less rain and higher temperatures, leaves may get too much sunlight and begin to burn, which prevents them from doing their job properly. 


Other regions are experiencing too much rainfall, leading to drenched soil and floods. Floods can damage plants by breaking their stems, pulling their roots from the ground, or even drowning them. As environments around the world continue to change, plants will struggle to change with it, which will be very problematic for animals and the rest of the environment.

Plant Parts Challenge

It is time to get outside!


For this challenge, you will exploring your neighborhood to find an example of a root, stem, leaf, flower, fruit, and seed. Once you have collected your plant parts, display them on the worksheet below. After observing and inspecting your plant parts, draw each part in the appropriate box.

Plant Parts Worksheet

Glossary


Anatomy

The study of an organism's body parts.

Flower

The reproductive part of a plant that contains pollen and is typically surrounded by petals.

Fruit

The part of a plant that contains and protects seeds.

Leaf

A flattened plant structure that grows from the stem or branches. This is where most photosynthesis happens.

Photosynthesis

The process used by plants and algae to change energy from the sun into sugar (energy) for the organism.

Plant

An organism that typically grows on land and uses photosynthesis to produce energy.

Pollination

The process of pollen being transferred between flowers to create fertile seeds.

Root

The part of a plant that is typically underground and is used to absorb water and nutrients from the Earth.

Seed

A structure produced by mature plants after pollination that can grow into a new plant.

Shoot System

A main organ of plants that includes the stem, leaves, flowers, fruits, and seeds.

Stem

The main, center structure of a plant that transports water and nutrients from the roots to the rest of the plant.
