Transport
What is the primary function of xylem in plants?
To transport water and minerals from the roots to the rest of the plant.
What is a plant's response to light called?
Phototropism, which is the growth response towards light.
What does the xylem carry?
Transports water and dissolved minerals.
What allows leaves to have their green pigment?
CHLOROPHYLL!
How do phloem and xylem differ in function?
Phloem transports nutrients and sugars produced by photosynthesis, while xylem transports water and minerals.
Define gravitropism
The growth of a plant in response to gravity, causing roots to grow downwards and shoots to grow upwards.
What does the phloem carry?
Sugars and other organic molecules.
What are the functions of the roots?
To anchor the plant into the soil and to absorb water and nutrients.
Describe how the structure of roots aids in the transport of nutrients.
Roots have a large surface area due to root hairs, which enhances absorption of water and minerals from the soil.
Define heliotropism
The growth of a plant in response to sunlight, causing leaves and flowers to turn towards the sun.
What are the two types of vascular tissues?
Phloem and xylem
Where is the location of photosynthesis on a plant?
LEAVES!
What role do stomata play in the transport of gases in plants?
Stomata are openings on the leaf surface that allow for gas exchange, facilitating the transport of carbon dioxide in and oxygen out.
Define thigmotropism
The growth of a plant in response to touch or contact, causing tendrils to wrap around objects.
What is the root cortex responsible for?
Storing food and water, and facilitating the absorption of nutrients from the soil.
What is the importance of the flower?
It houses the reproductive structures of a plant.
Explain how the vascular system of a plant supports transport functions.
The vascular system consists of xylem and phloem tissues that work together to efficiently transport water, nutrients, and sugars throughout the plant.
Use tropism in a sentence
Plants exhibit various tropisms, allowing them to adapt to their environment and optimize their growth.
Use stomata in a sentence
The stomata on a leaf's underside open and close to regulate the intake of carbon dioxide for photosynthesis and the release of oxygen and water vapor.
Cell elongation, stem growth, and root development.
