What else can I help you with?
True or false spongy mesophyll are cells in a leaf?
True. Spongy mesophyll cells are found in the leaf tissue of plants and are involved in the exchange of gases necessary for photosynthesis.
All energy in the biosphere comes from the sun true or false?
True. The sun is the ultimate source of energy for nearly all life on Earth through the process of photosynthesis, where plants and other photosynthetic organisms convert sunlight into chemical energy.
Is the following sentence true or false More runoff generally means less erosion?
False. More runoff can actually lead to more erosion, as the increased water flow can carry away soil particles and contribute to erosion.
How true or false A northerly wind comes from the south and moves toward the north?
False. A northerly wind comes from the north and moves towards the south.
Earth is closest to the sun during the month of January true or false?
False. Earth is actually closest to the sun during the month of January.
The principal organs in which plants carry out photosynthesis are leaves true or false?
True. Leaves are the primary organs where photosynthesis takes place in plants. They contain chlorophyll, the pigment responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis.
Is it true or false oxygen released in photosynthesis comes from water?
True
Increasing the intensity of light decreases the rate of photosynthesis true or false?
False. Increasing the intensity of light typically increases the rate of photosynthesis, up to a certain point where other limiting factors may come into play.
True or false photosynthesis produces the carbon dioxide that most living things need to survive?
FALSE
Do plants carry water to the roots true or false?
no
True or false blood vessels that carry blood to the heart are called arteries?
False. Blood vessels that carry blood away from the heart are called arteries. Blood vessels that carry blood to the heart are called veins.
True or false As light intensity increases indefinitely the rate of photosynthesis increases indefinitely?
False. There is a limit to the rate of photosynthesis even as light intensity increases. Once the saturation point is reached, the rate of photosynthesis remains constant.
True or False Do Ribosomes carry out lipid synthesis?
False. Ribosomes do not carry out lipid synthesis. Lipid synthesis occurs in the endoplasmic reticulum and other organelles within the cell. Ribosomes are responsible for protein synthesis.
Most veins carry deoxygenated blood true or false?
It is very true that most all veins carry deoxygenated blood.
Does the smaller the load a river has the more sediment it can carry?
True or false?
True or false During photosynthesis carbon dioxide and water in the presence of light are used to form sugars and oxygen gas?
False.
Is it true that photosynthesis produces the carbon dioxide that most living things need to survive?
False.
