How do roots support the plant?
They gather water and nutrients from the soil. They also support the plant and keep it in place.
100
The male part of the flower that produces the pollen is called the ____________.
Anther
100
What is the difference between woody stems and green stems?
Woody stems help plants, such as trees and shrubs, stay upright in strong winds. They can help trees become very tall. Tall plants get more sunlight.
Other plants, such as dandelions and sunflowers, have green stems. These stems can also capture sunlight while they hold the plants up and support branches, leaves, and other parts.

Think back to the celery experiment.
What happened and why did it happen?
The leaves and tubes of the plant changed to the color of the water because it was being transferred throughout the plant.
100
In this picture, the plant is responding to _______?
Gravity
The roots of plants grow down toward the center of Earth in response to gravity. The stem of a plant grows in the opposite direction, away from the center of Earth.
This usually results in the stem growing upward.
200
How does the stem help the plant function?
The stem carries water and food through the plant. It also supports the leaves.
200
Name the three types of way plants with flowers can participate in pollination.
Pollinators
Wind
Self-pollination
200
Why do some plants need taproots as opposed to fibrous roots?
Taproots can get water from deeper underground, and do well in droughts. They can also store food.
Fibrous roots can quickly absorb water and nutrients near the soil’s surface. They also help stop soil erosion.
200
Food-carrying tubes are called ________.
Phloem.
200
T/F: Some plants can eat insects.
TRUE
EX: Venus Fly Trap
300
How do the leaves support the plant?
The leaves collect sunlight and make food for the plant.
300
When the pollinator brings pollen to another plant, the pollen must land on the ___________.
Stigma
300
How do needles of evergreens help the survival of the plant?
The needles of evergreens, such as pine trees, gather sunlight for the plant to make food. Their shape and waxy coating reduce water loss during dry weather.
300
What specific type of food travels in the phloem tubes?
Sugar made in a plant’s leaves moves through a system of food-carrying tubes.
300
What do seeds need in order to successfully grow into a plant?
It needs the right type of conditions.
Possible conditions to consider: Light, soil, water, nutrients
400
Name two examples of plant parts that serve the purpose of protecting the plant.
Thorns are sharp, pointed parts on some plants. They protect a plant from being eaten by animals.
Bark, a tree’s woody covering, protects it from cold temperatures and from animal damage.
Cacti live in dry areas and have spines instead of wide, flat leaves. Not having flat leaves reduces water loss. Spines also protect the cactus from animals.
400
The process of the pollen reaching the ovule in order to create a seed is called ____________.
Fertilization
400
What is one similarity between the reproduction of plants with cones and the reproduction of plants with flowers?
Male parts produce pollen
Female parts produce ovules
Fertilization occurs in both when the pollen reaches the ovule.
Both develop seeds that will grow in the right conditions.
400
T/F: Water moving through the water-carrying tubes, called xylem, follow this path:
Leaves --> Tube --> Roots
Water, taken in from the roots, moves through the tubes into the plant’s leaves so the leaves can use the water to make food.
400
What are some possible reasons a plant may respond to touch?
A leaf might curl up to protect a plant from damage or from being eaten.
For plants that eat insects, they also respond to touch when they feel an insect touch their leaves.
500
Different plants reproduce using different types of reproductive parts. Can you name all three we have learned?
Flowers
Cones
Spores
500
The ___________ is a hard part of the plant that helps protect it. They can sometimes be mistaken as leaves.
Sepal
500
What is one difference between the reproduction of plants with cones and the reproduction of plants with flowers?
The pollen produced by cones is carried by the wind while the pollen can be carried by pollinators, wind, or self-pollination for flowers.
500
Where can extra food carried by the food-carrying tubes be stored?
These tubes travel from the leaves, throughout the plant, and down to the roots. Some plant roots, like carrots, store extra sugar produced by the plant.
500
Why would a plant grow towards a window in a house?
Plants need sunlight to make food, so a house plant that sits in front of a window will grow toward the light.
