What is photosynthesis question answer?
Answer: Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas as raw materials.
What happens at noontime in the leaf of a plant?
Photosynthesis occurs only in the mesophyll layers of plant leaves and, in some instances, in mesophyll cells in the stem. Mesophyll cells are sandwiched between the leaf’s upper and lower epidermis and contain numerous chloroplasts, where photosynthesis takes place. Chloroplasts are incredibly small.
What is the revised equation for photosynthesis?
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
What is the final product of photosynthesis Mcq?
Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is a process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
Does photosynthesis occur at night?
Complete answer: Photosynthesis in plants occurs only during the day when there is the sunlight but plants respire throughout the day and night.
What is the main product of photosynthesis?
The products of photosynthesis are glucose and oxygen. Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2). (This is good news for organisms like humans and plants that use oxygen to carry out cellular respiration!)
What is the first step in photosynthesis?
The first step of photosynthesis is the absorption of light energy and the loss of electrons from chlorophyll. Photosynthesis is a process by the plant to produce food by absorbing light of a certain wavelength and used to convert water and carbon dioxide and minerals into oxygen-rich and energy-rich organic compounds.
What season is photosynthesis most active?
In the summer, the daily pattern of photosynthesis mainly follows the changes in light (i.e. uptake is intense in light and prevented in the dark). However, other environmental factors may restrict the light prescribed rate of photosynthesis.
What are some adaptations plant leaves have that help them survive?
Leaf Waxing Nearly all desert plants produce a waxy coating on their leaves or have prickly spines. These features help keep water from evaporating out of the leaves. This is an adaptation to help prevent dehydration in a desert climate.
What are the 3 stages of photosynthesis?
It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).
What are the 7 steps of photosynthesis?
Terms in this set (7)
- Step 1-Light Dependent. CO2 and H2O enter the leaf.
- Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.
- Step 3- Light Dependent. The electrons move down to enzymes.
- Step 4-Light Dependent.
- Step 5-Light independent.
- Step 6-Light independent.
- calvin cycle.
What are the important questions in Chapter 13 photosynthesis?
For students easy prepration, we have compiled the Important Questions for Class 11 Biology Chapter 13 Photosynthesis in Higher Plants. By practising these questions, students will revise all the important topics of this chapter. Also, they could find some of these questions in the examination.
How to answer the AQA test questions in photosynthesis?
The student moved the pondweed from a distance of 10 cm away from the light source in the first experiment, to 90 cm away in the second The student moved the pondweed from a distance of 10 cm away from the light source in the first experiment, to 30 cm away in the second
Which is the first acceptor of PS-II in photosynthesis?
Electrons from the excited chlorophyll molecules of PS-II are first accepted by 12. Non-cyclic photophosphorylation results in the production of 13. DCMU inhibits 14. Maximum photosynthesis occurs in 15. The first acceptor of CO2 in C4 plants is 16. The first product of C4 pathway is 17.
How are photosynthesis and respiration dependant on each other?
Both processes are dependant on each other. Respiration uses the end product of the photosynthesis (glucose in the form of food). To produce ATP for energy. In the process, carbon dioxide and water are released which photosynthesis uses to produce more sugars.
