Does cellular respiration occur in germinating peas?
All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. Peas undergo cell respiration during germination.
How does cellular respiration occur in peas?
All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. It is known that pea seeds undergo cell respiration during germination.
What evidence do you have that cell respiration occurred in peas explain?
Do you have evidence that cellular respiration occurred in peas? Explain. The amount of oxygen in the chamber decreased (the slope of the line was negative) for the germinating peas because the peas were taking in oxygen and converting their sugars into water and carbon dioxide.
Why do germinating peas respire more?
Germinating peas grow rapidly. This growth process requires a lot of energy for cell division, so the rate of respiration in germinating peas is high. One way to measure the rate of respiration is to measure the heat produced in the process.
What is the independent variable in seed germination?
Germination: The process by which a plant grows from a seed. Independent Variable: The condition we are changing in each treatment.
Why do germinating peas undergo cellular respiration quizlet?
Why do germinating peas undergo cell respiration? They are growing at a fast rate and need energy to grow, so they use cellular respiration.
What is the hypothesis of seed germination?
Hypothesis If there is water, oxygen and a suitable temperature in the surroundings, then the seed will germinate. A seed is an embryonic plant in a resting condition after the development of the embryo in the ovule of the plant stops.
What factors affect seed germination experiment?
Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence.
What are the independent and dependent variables in seed germination experiment?
Germination: The process by which a plant grows from a seed. Independent Variable: The condition we are changing in each treatment. Dependent Variable: The condition that changes in response to the independent variable.
What are the 5 steps of cellular respiration?
pulmonary ventilation. O2 into lungs from inspired air; CO2 out of lungs from expired air.
Why do germinated peas undergo cell respiration?
The oxygen consumed increases with time because the peas are res pirating, which require oxygen. Why do germinating peas undergo cell respiration? They are growing at a fast rate and need energy to grow, so they use cellular respiration.
Is chlorophyll needed in cellular respiration?
The cellular organelles necessary for photosynthesis include chloroplasts containing the green pigment and chlorophyll, which traps sunlight. Respiration is the process in which cells use food produced to release stored energy. Plants perform cellular respiration as well as photosynthesis.
Is oxygen used in cellular respiration?
oxygen is important in cellular respiration because it is used to help harvest energy from food molecules. Oxidative phosphorylation uses it directly and it becomes water after it accepts electrons. Where is oxygen used in respiration? In cellular respiration, oxygen is used in the cells to produce energy.
