Answer 2

Answer:

1. Xylem - Water

2. Phloem - Food

3. Osmosis - Semi permeable membrane

4. Root hair - Absorption of water

5. Active transport - Energy

6. Companion cells - Phloem

7. Loss of water from the plant - Transpiration

8. Diffusion - Higher to lower concentration

9. Micronutrients - Cu, Zn, Fe

10. Macronutrients - P, N, K

11. Trachieds - Xylem

12. Bark - Phloem

13. Central portion of the plant - Xylem

14. Leaf - Stomata

15. Sunlight, water , humidity - Factors of transpiration

Explanation:

XYLEM:

• It is associated with transport of water in plants.

• The components of xylem are tracheids, vessels, xylem parenchyma and xylem fibres.

• Xylem occupies the central portion of plant and hence called wood.

PHLOEM:

• Phloem is concerned with the transport of food materials across plant.

• The components of phloem are sieve elements, companion cells, phloem parenchyma and phloem fibres.

• Phloem occupies the peripheral portion of plant which is generally referred to as bark.

OSMOSIS:

• Osmosis refers to the transport of water molecules from a region of higher concentration of water to the region of lower concentration of water across semi permeable membrane.

ROOT HAIRS:

• Root hairs are minute hair like structure arising from the epidermis of root.

• They absorb water and dissolved minerals from the soil.

ACTIVE TRANSPORT:

• Active transport refers to the movement of molecules from a region of lower concentration to a region of higher concentration.

• It is an uphill process and uses energy. It is highly selective in nature.

TRANSPIRATION:

• The loss of water in the form of vapours through the opening of leaf is called transpiration.

• Stomata are the minute openings present in the surface of the leaf.

• Transpiration takes place through stomata and sometimes by lenticels.

• The factors affecting transpiration are sunlight, water and humidity.

DIFFUSION:

• It refers to movement of solute particles from a region of higher concentration to lower concentration.

• It is a downhill process. It does not require energy.

MINERAL NUTRITION:

• The mineral nutrition that are required in larger amounts for the growth and development of plants is called macro nutrients.

• The nine macro nutrients are nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), carbon (C), oxygen (O), sulphur (S), hydrogen (H), magnesium (Mg).

• The mineral nutrients that are required in trace amounts is called micro nutrients.

• The eight micro nutrients are boron (B), manganese (Mn), copper (Cu), zinc (Zn), iron (Fe), chlorine (Cl) , molybdenum (Mo), nickel (Ni).
