Study Notes
Plant Transport Systems
- Plants produce their own food through photosynthesis.
- They also absorb water and minerals from the soil.
- Two main processes occur in plants: water and mineral transport from roots to other parts, and food transport from leaves to other parts.
Root Functions
- Roots anchor the plant in the soil.
- Roots store food and other nutrients.
- Roots absorb water, crucial for photosynthesis.
- Roots absorb minerals from the soil.
Factors Influencing Transpiration
- Transpiration is the loss of water in gaseous form.
- Temperature affects transpiration rates, higher temperatures increase transpiration.
- Light intensity influences transpiration rates.
- Humidity affects transpiration, high humidity decreases transpiration.
- Wind increases transpiration rates.
- Water availability influences transpiration, more available water increases transpiration rates.
- Surface area plays a role, larger surface area increases water loss.
Transpiration Measurement
- Various methods are used to determine transpiration rates.
- Transpiration occurs through stomata, small pores on leaves.
Food Transport
- Glucose, produced in the leaves, is transported through phloem tissue to other parts of the plant.
- Sieve tubes facilitate continuous food transport from leaves to other parts.
Mineral Importance
- Minerals are essential for plant growth.
- Classified as macronutrients (needed in large amounts) and micronutrients (needed in small amounts).
Macronutrients
- Examples of macronutrients include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S).
Micronutrients
- Examples of micronutrients include boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), and zinc (Zn).
Plant Transport Systems
- Plants obtain food through photosynthesis and absorb water and minerals from the soil.
- Two main transport systems exist: one for water and minerals from roots, another for food from leaves.
Roots: Functions
- Anchor plants to the soil for stability.
- Store food and nutrients.
- Absorb water essential for plant processes.
- Absorb minerals from the soil.
Factors Affecting Transpiration
- Temperature: Higher temperatures increase transpiration rate.
- Light: Light intensity affects transpiration rate.
- Humidity: High humidity decreases transpiration rate.
- Wind: Wind increases transpiration rate.
- Water Availability: More available water increases transpiration.
- Surface Area: Larger surface area leads to increased water loss (transpiration).
Transpiration
- Loss of water in gaseous form.
- Measured through various techniques to determine the rate.
- Occurs primarily through small pores in leaves called stomata.
Transport of Food and Substances
- Glucose is produced in the leaves during photosynthesis.
- Glucose is transported throughout the plant via phloem tissue.
- Sieve tubes within the phloem facilitate continuous food transport.
Importance of Minerals
- Essential for plant growth and development.
- Classified as macronutrients (needed in large amounts) or micronutrients (needed in small amounts).
Macronutrients
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K)
- Calcium (Ca)
- Magnesium (Mg)
- Sulfur (S)
Micronutrients
- Boron (B)
- Chlorine (Cl)
- Copper (Cu)
- Iron (Fe)
- Manganese (Mn)
- Molybdenum (Mo)
- Zinc (Zn)
