​

​Photosynthesis

Al Bawadi School​

Why do plants need sunlight?

​Photosynthesis is a series of chemical reactions that plants use to make their own food.

​

Plants use photosynthesis to produce oxygen​

Multiple Choice

The products of photosynthesis are:

• Sugar (glucose), Oxygen, water

• Carbondioxide, water, energy

Multiple Choice

The reactants of Photosynthesis are:

• Carbon dioxide, water

• Sugar (glucose), oxygen

Multiple Choice

The three things plants need are Sunlight, Water, and Carbon dioxide for photosynthesis

• True

• False

Multiple Choice

What is the ultimate source of energy for all living things?

• Sun

• Plants

• Food

• Electricity

Multiple Choice

The process by which plants make their own food is called the ......................

• Photosynthesis

• Cellular respiration

Multiple Choice

The sugar organisms need to convert to energy is called

• Glucose

• Sucrose

Multiple Choice

Through the process of photosynthesis, a century plant uses sunlight to make food. The equation below shows this process.

Light Energy + Carbon Dioxide + Water → Glucose + Oxygen

What happens to the light energy that the century plant uses for photosynthesis?

• The light energy is destroyed during the chemical reaction.

• The light energy is released into the atmosphere as water vapor.

• The light energy is transformed into chemical energy in glucose.

• The light energy is transformed into thermal energy and oxygen.

Multiple Choice

Carbon cycles among Earth's air, ground, and organisms. The diagram models part of the carbon cycle. Which of the following best describes the process that occurs at arrow X?

• Plants release carbon dioxide into the air through decomposition.

• Plants take in carbon dioxide from the air to perform photosynthesis.

• Plants release carbon dioxide into the air as a waste product

  of photosynthesis.

• Plants release carbon dioxide into the air as a waste product of

  cellular respiration.

Multiple Choice

Which of the following correctly combines the organelle with its function during photosynthesis?

• vacuole contains chlorophyll which absorbs nutrients

• chloroplast contains chlorophyll which absorbs sunlight

• mitochondria converts energy into food

• cytoplasm converts food into energy

Multiple Choice

One living plant leaf, still attached to the plant, is placed into a cup and covered with water. A light source is placed so that it shines into the cup on the leaf. In moments, bubbles appear on the surface of the leaf. Which statement explains what causes the bubbles to appear?

• Photosynthesis is occurring and the bubbles of carbon dioxide gas are being released by the plant.

• Photosynthesis is occurring and bubbles of oxygen gas are being released by the surrounding area and absorbed into the plant.

• Photosynthesis is occurring and bubble of oxygen gas are being released from the plant.

• Photosynthesis is occurring and bubbles of air are entering the water from the area around the plant.

Multiple Choice

What gives the leaf its green color and absorbs sunlight?

• stomata

• chlorophyll

• roots

• flowers

Multiple Choice

Location inside of a plant cell where the process of photosynthesis occurs.

• nodules

• stomata

• chloroplasts

• chlorophyll
