Why is the upperside of a leaf smoother and waxier than the underside

• As the upperside of the leaf faces the sun the water in the leaf will evaporate

• To attract sunlight so they can make food

• Due to the presence of chlorophyll

• To keep the flies away

What is the function of veins in a leaf

• To distribute food,water and mineral

• To make food from sun and absorb water from soil

• None of these

This long part of the plant acts like an "elevator" carrying water and nutrients to the leaves and flower part of the plant.

• roots

• stem

• leaves

• flower

Plants need the following:

• air, water, space, sunlight

• air, water, oxygen, space

How does the ozone layer help life on Earth?

• It produces oxygen for the atmosphere.

• It protects Earth from meteors.

• It absorbs damaging ultraviolet radiation from the Sun.

• It reflects most of the Sun's radiation to keep the planet cool.

How do transpiration and evaporation compare?

• During both processes, liquid water changes to water vapor.

• During both processes, water vapor changes to liquid water.

• During transpiration, liquid water changes to water vapor, and during evaporation, water vapor changes to liquid water.

• During transpiration, water vapor changes to liquid water, and during evaporation, liquid water changes to water vapor.
