Parts of a plant

What is a plant?

• A plant is a type of animal that lives in water.

• A plant is a mineral that does not require sunlight.

• A plant is a fictional character in a story.

• A plant is a living organism that performs photosynthesis and belongs to the kingdom Plantae.

Answer explanation

The correct answer defines a plant as a living organism that performs photosynthesis, which is a key characteristic of plants. The other options incorrectly describe plants as animals, minerals, or fictional characters.

What process do plants use to convert sunlight into energy?

• Photosynthesis

• Respiration

• Transpiration

• Fermentation

Answer explanation

Plants use photosynthesis to convert sunlight into energy. This process involves taking in carbon dioxide and water, and using sunlight to produce glucose and oxygen, making photosynthesis the correct answer.

Which part of a plant is primarily responsible for absorbing water and nutrients from the soil?

• Stem

• Leaf

• Root

• Flower

Answer explanation

The root is the part of the plant primarily responsible for absorbing water and nutrients from the soil. It anchors the plant and facilitates the uptake of essential minerals and moisture needed for growth.

What is the main gas that plants take in during photosynthesis?

• Oxygen

• Carbon Dioxide

• Nitrogen

• Hydrogen

Answer explanation

During photosynthesis, plants primarily take in carbon dioxide (CO2) from the atmosphere. This gas is essential for the process, as it is converted into glucose and oxygen, making carbon dioxide the main gas utilized.

What is the primary function of the leaf in a plant?

• To anchor the plant in the soil

• To absorb sunlight and perform photosynthesis

• To transport nutrients

• To produce seeds

Answer explanation

The primary function of the leaf is to absorb sunlight and perform photosynthesis, which is essential for converting light energy into chemical energy, allowing the plant to produce food.

Which type of plant reproduces through spores?

• Flowering plants

• Ferns

• Cacti

• Conifers

Answer explanation

Ferns reproduce through spores, which are produced in sporangia. Unlike flowering plants, cacti, and conifers that reproduce via seeds, ferns have a distinct life cycle involving spore formation.

What is the role of chlorophyll in plants?

• To absorb water

• To give plants their green color and absorb sunlight

• To store energy

• To transport nutrients

Answer explanation

Chlorophyll is essential for photosynthesis, allowing plants to absorb sunlight and convert it into energy. It also gives plants their green color, making the correct choice: 'To give plants their green color and absorb sunlight'.
