3. Xylem and phloem
4. Micronutrients and macronutrients
Answer these questions.
1 How does transport of material tal​

Answer 1

Explanation:

1. One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

2. Diffusion is the movement of particles from a high concentration to a low concentration. ... Active transport is the movement of particles from an area of low concentration to an area of high concentration. This process requires energy (ATP).

3.Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. ... Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus.

4.Micronutrients are the vitamins and minerals that our bodies need each day in order to properly function. Unlike macronutrients (carbohydrates, proteins and fats) which are needed in large amounts, micronutrients are only required in small amounts, hence the appropriate name

Answer 2

Answer:

Hey mate here is your answer.//

Explanation:

Differentiation between Diffusion and Osmosis:-

Diffusion:-

• Diffusion is a physical process in which molecules move from a region of higher concentration to a region of lower concentration.

• It occurs only in gaseous or liquid medium.

• Diffusion of molecules continues till homogeneity is attained. In this situation, rate of movement of molecules in both directions becomes same.

Osmosis:-

• Osmosis is a physical process in which ions migrate from a region of higher concentration to a region of lower concentration.

• It occurs only in liquid medium.

• Movement of solvent molecules continues till homogeneity is attained. in this situation, rate of movement of solvent molecules in either side of semi permeable becomes same.

Differentiation between Diffusion and active transport:-

Diffusion:-

• Diffusion is a physical process in which molecules move from a region of higher concentration to a region of lower concentration.

• Diffusion does not require cellular energy.

• It allows ions to pass in the cell membrane through a concentration gradient.

Active transport:-

• In this process, the mevements of substances occurs from a region of lower concentration to a region of higher concentration.

• Active transport utilizes cellular energy in the form of ATP.

• It pumps molecules through the cell membrane against the concentration gradient.

Differentiation between Xylem and Phloem:-

Xylem:-

• It carries water from roots to leaves and provide mechanical support.

• Cell wall is thick

• Xylem is made up of dead cells.

Phloem:-

• It stores and transports food from leaves to other parts of the plants.

• Cell wall is thin.

• Phloem is made up of living cells.

Differentiation between micronutrients and macronutrients:-

Micronutrients:-

• The mineral elements, that are required in minute quantity for normal growth of plants, are called micronutrients.

• Examples are Iron, Chlorine Boron, Manganese, Zinc, Copper, Nickel etc.

Macronutrients:-

• The mineral elements that are required in large quantities for normal development of plants, are called macronutrients.

• Examples are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulphur etc.
