Do all plant tissues have the same rate of photosynthesis?
ChuckDaniels57809
The degree of stomatal openings in plant leaves is influenced by how turgid (rigid) the plants guard cells are. When a plant is subjected to substancial light, ions are pumped into the guard cells. The more ions (hence light) means the larger the stoma will open. When the stoma is opened, water and nutrients from the plants roots (osmosis) travel up the plants xylem and is lost through evaporation at the stoma. this is called transiration. the larger the stomatal opening, the higher the transpiration (water travelling) rate. the stoma opens for photosynthesis (intake of CO2) and at the same time water is lost. to save water the stoma does not open at night when there is no sunlight for photosynthesis. So to answer the question, transpiration rate in plants will increase when subjected to higher light intensities and slow when there is no light.

∙ 12y agoEffect of Light on Plant Transpiration
Experiment by Bradley, Grade 6
Entered in the 2001/2002 Science Fair
Problem
Do plants transpire at the same rate under different sources of light?
Hypothesis
Plants transpire at the same rate under different sources of light.
Procedure
Pull the plastic bottoms from soda bottles and fill the bottoms with potting soil. Cut the upper portions from the soda bottles and put them aside. Plant three plants of four different species in the soda bottle bottoms. Water each plant with one-fourth cup of water and fit the soda bottle tops over the plants to create a terrarium. Label the bottles to indicate the type of plant and light source. Plant each plant species in the all three light sources, sunlight, household lamp, and fluorescent lamp, for six hours. After the light exposure, remove the upper portions of the soda bottles. Remove the water from each container and measure the amount of water that transpired from each plant.
Results
The plants transpired at different rates when exposed to different light sources. The plants gave off the most water in sunlight and the least in household light.
Conclusion
Plants transpire at different rates when exposed to different light sources. The plants in this experiment all transpired at a greater rate in more intense light.

∙ 9y agoPlants transpire at the same rate with different source of light because light does not affect transpiration. Apart from cooling plants, transpiration allow the intake of carbon dioxide for photosynthesis.

∙ 10y agobecause they're different plants that evolved in different conditions
plants that evolved in dry environments transpire slowly to save water
plants that evolved in wet environments transpire quickly to speed up photosynthesis.

∙ 12y agoThere are a number of reasons:
The origin of the plant - plants originally from sub-tropical or tropical areas will transpire at a higher rate than those originally from arid or semi-arid areas.
The size of the plant (larger leaf surface area = more transpiration).
The metabolic rate of the plant = plants with a higher metabolism have a higher transpiration rate.
The amount of water in the soil - plants that have access to more soil water will transpire at a higher rate than those which don't.
Availability of nutrients - plants which have adequate nutrient supplies have higher metabolic rates than those which don't, and therefore transpire at a higher rate.

If you take a plant sitting in the sun and put it in a dark room will photosynthesis continue at the same rate?
Of course not because there would no photo, so to speak. In other words, there would be no light, and no way for the plant to use photo synthesis. Think about it this way: In greek I think it is, photo means "light".
Lab 4 AP Bio Plant Pigments and Photosynthesis?
Photosynthesis is a light reaction that happen in the chloroplast by wavelenght types
How are plant-like protists like plants?
its the same as a plant but it don't have a stem, roots, neither any leaves.
Why is oxygen not needed in photosynthesis?
Oxygen is not needed in photosynthesis. In fact it is produced by photosymthesis and eliminated from the plant as a waste product.Plants of course do need some oxygen for the same reason that we do. They use oxygen in respiration - the process in which food is 'burned' to release energy. However photosynthesis produces more oxygen than the plant uses up in respiration, so the excess isremovedfrom the plant into the atmosphere.For a very simple introduction to photosynthesis see http://www.bbc.co.uk/schools/ks3bitesize/science/biology/green_plants_1.shtmlFor more detail see http://www.biology4kids.com/files/plants_photosynthesis.html
How does photosynthesis and respiration in green plants meet the needs of the cell?
Respiration is an essential life process in plants. It is necessary for the synthesis of essential metabolites including carbohydrates, amino acids and fatty acids, as well as for the transport of minerals and other solutes between cells. It consumes between 25 and 75% of all the carbohydrates produced in photosynthesis at ordinary growth rates.
What is the effects of wilting point on plant growth?
Decreases by far. The wilting means there hasn't been much water added to the plant, so without the water the Photosynthesis doesn't exactly keep itself up. So the rate of Photosynthesis is about the same as the rate of being watered.
Is a tree the same as a plant?
A tree is a kind of plant. If it manufactures food for itself via photosynthesis..it is a plant.
How does a daffodil do photosynthesis?
The daffodil makes energy in the same manner as other plants. Photosynthesis is a process that converts light energy (from the sun) into chemical energy (sugar) that can be utilized to support the plant's tissues. It is also stored in the bulb for the next year's growth and flowering needs.
What are the functions of a dandelion plant petals?
Photosynthesis - same as tree leaves.
in which part plant produce oxygen?
The same as a land plant, by photosynthesis.
What organ of the plant that conducts light absorption?
Plant leaves that carry out photosynthesis absorb light energy for the same. By this, plant can synthesize the nutrient needed for its survial.
Is it true that an increase in light intensity will not increase the rate of photosynthesis?
No, that is not true and increasing light intensity increases the photosynthetic rate, to a point. The saturation point is reached when the reactions in the reaction center have reached top speed and any more light intensity will not increase the rate of photosynthesis.
Do all parts of body and plant broken down into same rate?
no
Are animals tissues and plant tissues different?
Plant and animal tissues are made up of hundreds of thousands of plant and animal cells (respectively). A plant cell is made up of many of the same components as an animal cell...but have some distinct and crucial differences. This is a Plant Cell: This is an Animal Cell: The biggest differences between the two is the presence of a cell wall, a cell membrane, a central vacuole and chloroplasts in a plant cell, and the absence of the aforementioned in an animal cell. :)
Are leaves tissues or organisms?
a plant is an organism ..the leaf is an organ ...same way a human is an organism and the heart is an organ
What would perform the same function as DPIP in the living plant?
NADP + would perform the same function. During photosynthesis electrons are transferred there.

Of course not because there would no photo, so to speak. In other words, there would be no light, and no way for the plant to use photo synthesis. Think about it this way: In greek I think it is, photo means "light".
