What Plants Need
True or false: All plants need the same amount of space to grow
False! Small plants like pansies or daisies do not need as much space. Lots of pansies can grow in the space that one tree needs.
In what two places do roots grow?
A stem is a plant structure that connects the ______ with the ______.
A stem is a plant structure that connects the roots with the leaves.
True or false: grasses, rose bushes, and maple trees all have green leaves.
True
What is the function of the vascular system?
The function is to carry food, water, and nutrients to all parts of the plant.
What do plants need in order to get the things they need to survive?
They need space to grow
Where on the roots does water and nutrients enter the plant?
root hairs
What types of stem does a tree trunk have?
A) thin and flexible
B) think and woody
C) thick and fleshy
D) thin and flaky
A tree trunk has a thick and woody stem
What is the purpose of the leaves of a plant?
The purpose of the leaves is to make food for the plant.
True or false: The vascular system is one big tube that carries everything the plant needs to all parts of the plant.
False! Like the one-way lanes of a highway, each kind of tube carries materials in only one direction at a time.
Where do plants get nutrients and why do plants need them?
Plants get nutrients from the soil in order to grow, develop, and stay healthy
What are the two main types of roots?
taproot and fibrus roots
What is the function of a plant's stem?
The function of a plant's stem is to support the plant and hold up the leaves so they can absorb sunlight.
Why are some plants' leaves needle shaped and waxy?
To prevent water loss
True or false: The vascular system brings water all the way from those leaves down to its roots.
False! The vascular system brings food all the way from those leaves down to its roots.
Where do plants get water?
Plants get water from underground.
What kind of roots are spread-out, similar in size, and take in water that is close to the surface?
Fibrous roots
What type of stem can store water or food?
Thick and Fleshy stems
What is the green substance that captures the energy in sunlight?
chlorophyll
Which direction does water travel in the vascular system? Up or down? Where does it go?
Water travels UP the vascular system to the leaves.
What four things do plants need to survive?
sunlight, air, water, and nutrients
What are the two main functions of a plants roots?
To anchor the plant and to take in nutrients and water from the soil.
Give an example of a stem that grows underground and can store food.
potatoes, onions, ginger
The process in which plants use energy from light to make food is called photosynthesis.
What does the plant need in order to undergo photosynthesis? What food is made and what is the waste product?
carbon dioxide + water + energy from the sun = glucose (sugar) + oxygen
Describe the path of water and nutrients and food in a plant in detail.
Water enters the plant through the roots. It travels up the stem using the vascular system up to the leaves.
The plant then makes food (glucose) through the process of photosynthesis.
The food then travels down the vascular system to the rest of the plant.
