Importance of Water
What process in plants requires water to make food?
(Answer: Photosynthesis.)
These special cells transport water by increasing surface area
Root hair cell
What process moves minerals into root hair cells?
(Answer: Active transport.)
What part of the plant anchors it in the soil and absorbs water and nutrients?
(Answer: Roots.)
The name for the pores in the green parts of plants
STOMATA!!!
What happens to plants when they lack water and lose turgor pressure?
(Answer: They wilt.)
Why do root hair cells have thin cell walls?
(Answer: To allow water to move into the cell easily.)
The term by which root hair cells take in minerals from the soil.)
answer: Mineral Absorption
What is the role of mineral ions in plants?
(Answer: They are essential for growth and development.)
What is the primary function of root hair cells?
(Answer: To absorb water and mineral salts from the soil.)
How does water help plants in hot environments?
(Answer: Water cools the plant by evaporating from the leaves, taking heat away.)
Name one structural feature of root hair cells that makes water absorption efficient.
(Answer: (Answer: Large surface area due to Their long, thin extensions.)
Name one mineral absorbed by root hair cells and its importance.
(Answer: Nitrate – essential for protein synthesis and plant growth.)
Why is active transport necessary for mineral uptake?
(Answer: Minerals are often at a lower concentration in the soil than in the root hair cell.)
Without a permeable membrane, this process cannot occur
What is osmosis?
Besides photosynthesis and cooling, name one other function of water in plants.
(Answer: Transporting nutrients around the plant.)
How do root hair cells maintain contact with water and minerals in the soil?
(Answer: They grow directly into the spaces between soil particles.)
What role does the vacuole play in mineral absorption?
(Answer: It stores absorbed minerals and maintains the concentration gradient for further absorption.)
How do environmental factors like soil moisture affect the function of root hair cells?
(Answer: Less soil moisture decreases water absorption, while more moisture increases osmosis.)
Why don’t root hair cells contain chloroplasts?
(Answer: They are underground and do not carry out photosynthesis.)
How does the large surface area of root hair cells aid osmosis?
(Answer: It increases the amount of water that can be absorbed at a time.)
Explain how the structure of root hair cells helps them absorb water and minerals efficiently.
(Answer: Root hair cells have long, thin extensions that increase surface area for absorption, thin cell walls for easy movement of water, and a large vacuole to maintain the concentration gradient for osmosis and store minerals. They grow close to soil particles to maximize contact with water and minerals
Explain how active transport and the structure of root hair cells work together to ensure efficient mineral absorption.
(Answer: Active transport moves minerals from low concentration in the soil to high concentration in the root hair cells using ATP. The large surface area of root hair cells, their thin walls, and close contact with soil particles maximize the efficiency of this process.)
Why don’t root hair cells perform photosynthesis?
(Answer: They are underground and do not contain chloroplast
This combination of structural adaptations in root hair cells
what is the importance of this combination of structural adaptations in root hair cells ; thin cell wall and a large surface area?)
allows water to enter the cells efficiently and move into the root system, ensuring the plant's survival.
