II Pottasium

III Manganese

IV Molybdenum

NECROSIS at the tips of roots or young leaves.

This is then followed by general CHOLOSIS and DOWNWARD HOOKING of young leaves.

DEFORMED young leaves.

These statements are specifically refer to which element deficiency?

What are the symptoms of plant with potassium deficiency?

Deficiency symptoms recorded by botanist include

the accumulation of sugars that favors the synthesis of anthocyanin in the leaves of the plant.

Which of the following functions are refer to the element that deficient?

I Promotes fruiting

II Promotes flowering

III Increases nitrogen fixation

IV Activates enzymes involved in photosynthesis

Which of the following statements are matched properly between the element and their function.

I Molybdenum - nitrate assimilation and nitrogen fixation

II Boron - cell elongation, DNA synthesis and cell cycle regulation.

III Zinc - enzyme activator for chlorophyll and auxin biosynthesis.

IV Calcium - synthesis of cell wall and cell division, act as a second messenger.

Which of the following statements is NOT TRUE about types of fertilizers used in Agriculture?

Which of the following statements describe the factors affected the absorption of salt in plants?

I The absence of oxygen increases the salt absorption by plants.

II The salt absorption inhibited or terminated as it past the maximum temperature.

III Light effects the opening and closing stomata. Opened stomata increases transpiration and salt absorption (potassium ion).

IV Hydrogen ion affected availability of ions in the soil solution. More alkaline soil (pH>7 - 14) favorable for the uptake of phosphorus (salt) by plants.

What are the factors that influence the absorption of salt by plants?

I Light

II Growth

III Hydrogen Ion

IV Oxygen Tension
