Explain how environmental factors affect the rate of transpiration in flowering plants​
Igoryamba

Explanation:

there are a couple of environmental factors that affect the rate of transpiration. they include:

I) wind:in a windy environment there is easy movement of moisture hence it does not accumulate on the leaf surface. this helps to increase diffusion gradient between the intercellular spaces in the leaf and in the environment there4 the rate of transpiration is increased. in a calm environment moisture accumulates on the surface of a leaf there4 reducing the diffusion gradient there4 reducing the rate of transpiration

ii) atmospheric pressure :in low lands there is high atmospheric pressure than in the highlands. the more the atmospheric pressure the more the pressure exerted on the cells of the leaves there4 reducing the rate of transpiration.

iii) humidity:the more the humidity in the atmosphere the less the rate of transpiration. this is due to low diffusion gradient due to accumulation of water vapour on the surface of the leaf

iv) temperature:a rise in temp increases the water vapour holding capacity of air in the air spaces within the spongy mesophyll layer. the water vapor pressure in the intercellular spaces increases causing an increase in diffusion gradient between the intercellular spaces and the environment there4 increasing the rate of transpiration. decrease in temp decreases the water vapor holding capacity in the intercellular spaces there4 diffusion gradient is lowered there4 reducing the rate of transpiration.

1. What is the original source of energy in the food you eat?
guajiro [1.7K]

Photosynthesis is similar to cellular respiration in the sense that the equation of one is the reverse of the equation of the other.

The original source of energy that is introduced into the ecosystem comes from the sun. This energy is passed along the food chain.

The equation that models cellular respiration is the equation; C6H12O6 + 6O2 → 6H2O + 6CO2 + Energy. Recall that cellular respiration involves the breakdown of glucose in the presence of oxygen. The compound that is involved in cellular respiration is oxygen.

The Calvin cycle is the light-independent (does not need light) step of photosynthesis and happens in the stroma.

The products of photosynthesis are carbon dioxide and water as we can see from the reaction; 6CO2 + 6H2O → C6H12O6 + 6O2.

Electrolysis does not form a part of cellular respiration. Glycolysis,  electron transport chain and the Krebs cycle are steps of cellular respiration.

The events shown in the picture occurs in the chloroplasts. The image shown the biochemical processes involved in photosynthesis.

During cellular respiration, glucose is split into its constituent molecules which are water and carbon dioxide when it reacts with oxygen.

The equation of photosynthesis is the reverse of the equation of cellular respiration.

What step occurs in the cristae?
Marina CMI [18]

Answer:

The electron transport chain and chemiosmosis takes place on this membrane as part of cellular respiration to create ATP and can be seen in the diagram: The cristae increase the surface area of the inner membrane, allowing for faster production of ATP because there are more places to perform the process
