Growth of Organisms

A science student planted two pinto bean seeds in pots with equal amounts of soil and water. She put one on a sunny window sill and the other in a dark closet. What do you predict will happen?

• Neither of the plants will grow.

• The plant in the dark will grow more.

• The plant in the sunlight will grow more.

• The two plants will grow equally.

Nonliving factors that affect the ecosystem are light, space, temperature, shelter, water, and soil composition.

• Growth

• Environmental factors

• Abiotic factors

• Biotic

Growth

• Process of increasing in size and maturity

• Traits plants inherit that help them to survive

• Things that result from the specific alleles carried by an individual

• Factors that are living or produced by living things

Which of the following is an example of an environmental factor that would affect plant growth?

• A plant's ability to store water

• A drought or flood

• A plant's method of reproduction

• A plant's method of protection

Which of these is an example of a biotic factor that affects plant growth?

• The amount of rainfall

• Insects or animals that feed on plants

• The amount of sunlight

• None of these

What materials do plants need to live and grow?

• Water, nutrients, nitrogen, sunlight, and oxygen

• Water, carbon dioxide, oxygen, nitrogen, and space

• Water, carbon dioxide, nutrients, space, and sunlight

• Carbon dioxide, nitrogen, oxygen, and glucose

Any factor, whether abiotic or biotic, that influences living organisms

• biotic

• genetic factors

• environmental factors

• adaptation

Which of these is an example of an abiotic factor that affects plant growth?

• The amount of water

• The type of soil

• The amount of sunlight

• All of these

Things that result from the specific alleles carried by an individual

• growth

• biotic

• environmental factors

• genetic factors

Which of these is a method of seed dispersal that helps plants to survive?

• attaching to the coat or fur of animals
