Photosynthesis & Cellular Respiration

Understanding the process by which plants convert sunlight into energy

Multiple Choice

A cell is...

• the basic unit of structure and function in living organism
• an organism
• a basic part of everything that we see
• found only in animals, not plants

Multiple Choice

Every living organism is made up of one or more cells

• True
• False

Multiple Select

An amoeba is a unicellular organism. This is an example of all living things...

• Growing and Developing

• Responding to Stimuli

• Reproducing

Photosynthesis Summary

• Photosynthesis is the process by which plants convert sunlight into energy.
• It occurs in the chloroplasts of plant cells.
• During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen.
• This process is essential for the survival of all living organisms on Earth.

Photosynthesis

Photosynthesis is the process by which plants convert sunlight into energy. It is a vital process for the survival of plants and the production of oxygen. During photosynthesis, plants use chlorophyll to capture sunlight and convert it into glucose, which is used as energy. Without photosynthesis, life on Earth would not be possible.

Factors Affecting Photosynthesis

• Light intensity: Higher intensity increases photosynthesis rate.
• Carbon dioxide: More CO2 leads to increased photosynthesis.
• Temperature: Optimal range enhances photosynthesis.
• Water availability: Adequate water is crucial for photosynthesis.
• Chlorophyll concentration: Higher concentration boosts photosynthesis.

Multiple Choice

What is the process by which plants convert sunlight into energy?

• Respiration

• Fermentation

• Photosynthesis

• Transpiration

Multiple Select

Select all that are products of Photosynthesis.

• Water

• Carbon Dioxide

• Oxygen

• Sunlight (Light Energy)

• Glucose (Sugar/food)

Multiple Choice

What three things do plants need?

• Water, air, and sunlight.

• Water, soil, and sunlight.

• Water, soil, and air.

• Love, family, and Cheetos.

Multiple Choice

Why do plants conduct photosynthesis?

• To make light
• To make mitochondria
• To make glucose
• To release carbon dioxide

Multiple Choice

How does most of the water needed by the plant get into its leaves?

• It enters through the stomata

• The roots absorb it and then it travels up the stem

• It's made during a chemical reaction in the leaf

• The flowers capture water and deliver it to the leaves

Multiple Select

Select all that are raw materials for Photosynthesis.

• Water

• Carbon Dioxide

• Oxygen

• Sunlight (Light Energy)

• Glucose (Sugar/food)

Multiple Select

Select all that are products of Photosynthesis.

• Water

• Carbon Dioxide

• Oxygen

• Sunlight (Light Energy)

• Glucose (Sugar/food)

Multiple Choice

What is the green pigment that "traps" sunlight?

• Chlorophyll

• Chloroplasts

• Photosynthesis

• ATP

Introduction to Cellular Respiration

• Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

• It occurs in the mitochondria of cells.

• Importance: It is the main way cells generate energy to perform their functions.

• Cellular respiration is essential for all living organisms to produce ATP, the energy currency of cells.

Comparison of Photosynthesis & Cellular Respiration

• Photosynthesis: The process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen.

• Cellular Respiration: The process by which cells break down glucose and oxygen to produce energy, carbon dioxide, and water.

• Comparison: Photosynthesis occurs in chloroplasts, while cellular respiration occurs in mitochondria. Photosynthesis produces oxygen, while cellular respiration uses oxygen. Both processes are essential for life on Earth.

Multiple Choice

What is cellular respiration?

• The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

• The process by which cells convert carbon dioxide and water into glucose and oxygen.

• The process by which cells convert sunlight into energy.

• The process by which cells convert water into oxygen.

Multiple Choice

All organisms use photosynthesis and respiration.

• true

• false

Photosynthesis

Trivia: Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. It is the primary source of oxygen in the atmosphere and plays a crucial role in the Earth's ecosystem. Without photosynthesis, life as we know it would not be possible. Chlorophyll, the pigment responsible for capturing sunlight, gives plants their green color. Cellular Respiration, Mitosis, and Fermentation are not the correct processes for this conversion.

Multiple Select

What are the products of cellular respiration? Choose 3.

• water

• ATP

• Oxygen

• Sunlight

• Carbon Dioxide

Multiple Choice

Where in the cell does cellular respiration occur?

• endoplasmic reticulum

• mitochondria

• the nucleus

• chloroplast

Multiple Choice

What is the purpose of having mitochondria in plant cells when they already have chloroplast?

• to store water

• to transform energy from sunlight into sugar

• to transform sugar into energy

• to store nutrients

Multiple Choice

The ___ is the cell part (organelle) inside cells where cellular respiration happens.

• mitochondria

• chloroplast

• nucleus

• ribosome

Multiple Choice

___ is the process that cells use to take energy from glucose.

• cellular respiration

• photosynthesis

• transpiration

• excretion
