- RESPIRATION AND THE ENVIRONMENT
- The act or process of breathing in plants and animals is known as ____ Respiration.
- In animals it is the ______ inhaling of oxygen and the _______exhaling of carbon dioxide.
- In Plants, it is the process by which cells use oxygen to break down sugar and obtain ______ energy.
- Thus, in transpiration plants take in ______ carbon dioxide during the day and send out ______oxygen while animals take in _____ oxygen and send out
_______ carbon dioxide.
- During the night plants take in ____________ oxygen and send out _______ carbon dioxide.
- IMPORTANCE OF RESPIRATION TO PLANTS
- The carbon dioxide breathed out by animals is important to plants. It is used to manufacture plant food in the process of__________ photosynthesis.
- During the day plants take in carbon dioxide and send out oxygen which refreshes the __________. atmosphere.
- Photosynthesis and respiration are the two essential processes that _______ allow life to sustain on earth.
- TRANSPIRATION is the process through which plants lose water to the surrounding atmosphere in the form of__________. water vapor
- This water escapes through tiny holes on the leaves called________ stomata.
- The importance of transpiration to plants are_________
- It helps to ___________ the plant. cool
- It helps to remove___________ from the plant. excess water
- The transpiration pull helps to absorb _____________ dissolved in water from the soil. minerals
- Some factors affecting transpiration are ____________
- The ______ of the atmosphere. humidity
- The number of _____________ present on the leaves. stomata
- The ________________ of the environment. temperature
- The amount of soil_____ water.
- The __________ of the wind. speed
- Plants control the rate of transpiration by _______Leaf folding, Leaf shedding, Leaf dropping, and by Water storage organs.
- An example of plants that fold up their leaves during hot weather to reduce the rate of transpiration is ________ groundnuts (Peanuts)
- An example of plants that shed their leaves to reduce the rate of water loss is the ______ pear tree.
- An example of plants that drop their leaves during hot weather to reduce the rate of water loss is ______ sweet potatoes
- Some plants develop water storage organs. That is, thick leaves and thick bark to fight _______ Transpiration
- IMPORTANCE OF TRANSPIRATION TO MAN AND HIS ENVIRONMENT
- Water evaporates from plants into the atmosphere and forms tiny droplets of water called clouds which later become heavy and fall back as ___ rain.
- Rain waters our_________ crops
- It provides us with ___________ if well collected. drinking water
- We use the water to cook our________ food
