Why boiled seeds do not respire?

Boiled seeds won’t grow – evidence that they have been killed by the boiling process. The high temperature irreversibly destroys crucial proteins in the plant cells, including structural proteins, so the cells fall apart (that’s why the water goes green when you boil them) and cease respiration.

Can boiled seeds respire?

Boiled seeds do not respire and so no results will be obtained if they replace the germinating seeds in the experiment.

What happens when we boil the germinating seeds and why?

Cell organelles essential for germination are destroyed when seeds are boiled, the protein content of the cells, their bonds and structures are disrupted. Additionally, boiling seeds also destroy the enzymes required for germination. This destroys cells, causing death. Following this, cells do not grow and divide.

Why is the boiled seeds the control?

Seeds lose their ability to germinate after boiling. This is because boiling denatures composition of the cells that make up the seeds. Using boiled seeds acts as the control set up for the experiment as they neither germinate nor respire. Hence, the control set up will not use up any oxygen.

Do seeds respire?

Some seeds have been soaking in water. When plants use sugars stored in their leaves or seeds they undergo cellular respiration. … As the seeds respire, they are taking in oxygen and respiring out carbon dioxide, but the carbon dioxide is being absorbed by the calcium hydroxide.

Why do germinating seeds respire more?

In order for seeds to acquire the necessary energy to develop and grow, germinating seeds undergo cellular respiration. Hence, there is a high rate of consumption of oxygen in seeds that are germinating as they are living and need extra oxygen to grow. …

Why do non germinating peas respire less?

In non-germinating peas, they aren’t going through mitosis and therefore don’t need as much ATP, so their rate of cellular respiration is much less.
