Which of these is a waste product from photosynthesis?
Which of these is a waste product from photosynthesis?
oxygen
Why is o2 a waste product in photosynthesis?
Answer. Oxygen is released by plants after photosynthesis as a waste because plants require carbon dioxide water and sunlight to synthesis glucose. So the waste products are oxygen glucose and energy which are utilised by other living organisms.
Is carbon dioxide produced in cellular respiration?
During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.
How are plants deal with excess water and waste product of photosynthesis?
Answer: Oxygen released during photosynthesis is used for respiration while carbon dioxide released during respiration is used for photosynthesis. Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems. Eventually, plants shed off these parts.
How do plants get rid of the waste products?
The waste products of a plant are carbon dioxide, water vapour and oxygen. While carbon dioxide and water vapour are waste products of respiration, oxygen is a waste product of photosynthesis. These waste products are removed through stomata in leaves and lenticels in stems and are released into the air.
How do plants excrete their waste products?
Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration. Excretion of gaseous waste in plants takes place through stomatal pores on leaves. Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.
Where does plant store waste products?
- Vacuoles are single membrane-bound structure. The membrane of the vacuoles is known as tonoplast.
- Most plants store their waste material in cellular vacuoles. Some plants store waste material in the leaves which fall off, while some store it in the form of resins and gums.
Where are resin and gums preserved?
Old Xylem
How does photosynthesis and respiration Minimise the production of excretory matter in plants?
Answer: The method used by plants to get rid of excretory products are as follows: (i) The oxygen, end product of the photosynthesis gets removed through stomata. (ii) The carbon dioxide which is produced during the process of respiration also gets removed through stomata.
Which process expels excess water from plants?
transpiration
Do you think excess amount of water was used while watering the plants if yes why do you think so?
Answer: If there is too much water or the soil is constantly wet, there is not enough air pockets. This results in a limited oxygen supply and plants are not able to breathe. When plants have too little water, leaves turn brown and wilt.
Which process takes place at the pores of plants?
Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores — called stomata — to take in carbon dioxide and release oxygen.
What are plant pores called?
Stomate, also called stoma, plural stomata or stomas, any of the microscopic openings or pores in the epidermis of leaves and young stems.
