EOY Cumulative Science Benchmark 2nd Grade: Part 1

What happens to plants without sunlight?

• They will continue to grow normally.

• They will not be able to photosynthesize and will eventually die.

• They will produce more flowers than usual.

• They will thrive in low-light conditions.

What is seed dispersal?

• The process of planting seeds in the ground.

• The method by which seeds are spread away from the parent plant to grow in new locations.

• A technique used to water plants effectively.

• The act of collecting seeds from various plants.

What is a habitat?

• A habitat is a type of food chain.

• A habitat is the natural environment where an organism lives and grows.

• A habitat is a type of animal.

• A habitat is a scientific method of studying organisms.

What is the role of water for plants?

• Water is used by plants to produce flowers.

• Water helps plants to transport nutrients, maintain structure, and perform photosynthesis.

• Water is primarily used for plant reproduction.

• Water acts as a pesticide for plants.

What is the importance of bees in nature?

• Bees help in pollination, which is essential for the reproduction of many plants.

• Bees produce honey, which is a primary food source for many animals.

• Bees are important for maintaining the temperature of the earth.

• Bees help in the decomposition of organic matter.

How do birds help in seed dispersal?

• By building nests in trees and dropping seeds from there.

• By eating fruits and then dropping the seeds in their droppings.

• By pollinating flowers that produce seeds.

• By carrying seeds in their beaks to new locations.

What do plants need to grow?

• Sunlight, water, and nutrients from the soil

• Only water and sunlight

• Air and carbon dioxide

• Just nutrients from the soil

What is photosynthesis?

• Photosynthesis is the process by which plants use sunlight to make their own food from carbon dioxide and water.

• Photosynthesis is the process by which animals convert food into energy.

• Photosynthesis is the method by which plants absorb nutrients from the soil.

• Photosynthesis is the way in which plants reproduce sexually.

What can happen to plants if they are kept in a dark place?

• They may thrive and grow faster.

• They may die due to lack of sunlight.

• They will produce more flowers.

• They will develop stronger roots.

What is the wind's role in seed dispersal?

• The wind helps seeds to grow in the same area as the parent plant.

• The wind can carry seeds away from the parent plant to help them grow in new areas.

• The wind prevents seeds from germinating by blowing them away.

• The wind only affects the direction of seed growth, not their dispersal.
