photosynthesis Flashcards
What is photosynthesis?
The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
True or False: Photosynthesis occurs only in the presence of sunlight.
True
Fill in the blank: The primary pigment involved in photosynthesis is _____ .
chlorophyll
What are quadrats used for in ecological studies?
Quadrats are used to sample and study the distribution and abundance of organisms in a specific area.
Multiple Choice: What is the main purpose of using pitfall traps in ecology?
To capture small animals for the study of biodiversity.
True or False: Quadrats can be used to measure the density of plant species.
True
What is the role of light intensity in photosynthesis?
Light intensity affects the rate of photosynthesis; higher light intensity typically increases the rate.
Fill in the blank: The formula for photosynthesis can be summarized as _____ + _____ → glucose + oxygen.
carbon dioxide, water
What is the significance of using a control in experiments involving photosynthesis?
To establish a baseline for comparison and ensure that results are due to the variable being tested.
True or False: Farming practices can influence the rates of photosynthesis in crops.
True
What is the effect of increased carbon dioxide levels on photosynthesis?
Increased carbon dioxide levels can enhance the rate of photosynthesis up to a certain point.
Fill in the blank: The study of populations within a quadrat is known as _____ analysis.
population
Multiple Choice: Which method is commonly used to estimate plant biomass in quadrats?
Dry weight measurement
What type of organisms are typically captured using pitfall traps?
Insects and small terrestrial animals.
True or False: The size of a quadrat can affect the reliability of ecological data collected.
True
