Science 4 Second Summative Test

What do you think is the primary reason why plants along the roadside may struggle to grow healthy?

• Lack of sunlight

• Excessive watering

• Pollution from passing vehicles

• Too much fertilizer

In a garden, you notice a plant's leaves with a hole and brown spots. What is the most likely cause of this issue?

• Overwatering

• Insect infestation

• Lack of nutrients

• Proper care

A tree growing alongside a busy road has developed a bent and curved trunk. What is the most likely reason for this?

• Pollution

• Strong winds

• Soil erosion

• Inadequate watering

What is one of the primary functions of a plant's root system?

• Photosynthesis

• Anchoring in the soil

• Capturing sunlight

• Producing flowers

Why do national parks and roadside landscapes encourage planting more native plant species?

• They are more colorful.

• They could adapt easily and require less maintenance.

• They deter wildlife.

• They grow faster.

How do leaves contribute to the shoot system's functions?

• By anchoring the plant in the soil

• By absorbing water and nutrients

• By capturing sunlight for photosynthesis

• By producing flowers and seeds

In some countries like Japan or Australia, some trees along a roadside have bright red or orange leaves during the fall. What is the likely reason for this change in color?

• Disease

• Lack of nutrients

• Adaptation

• Insect infestation

What is the main function of stems in the shoot system of a plant?

• Absorbing water and nutrients

• Anchoring the plant in the soil

• Transporting water and nutrients

• Capturing sunlight for photosynthesis

Why is it important for a plant to have both root and shoot systems?

• Root systems produce oxygen, and shoot systems produce carbon dioxide.

• Root systems store excess water, and shoot systems release excess water.

• Root systems absorb water and nutrients, while shoot systems capture sunlight and perform photosynthesis.

• Root systems anchor the plant in the soil, and shoot systems produce carbon dioxide.

When you observe a plant with well-developed root and shoot systems, you can conclude that:

• The plant is unhealthy and needs more care.

• The plant is undergoing a growth spurt.

• The plant is likely thriving and has adapted to its environment.

• The plant will produce fewer flowers and fruits.
