What is the relationship between the stoma and air space?
Stomata are the external access point to the internal air space. Oxygen & carbon dioxide, water vapor as well. During times when there is a lot of photosynthesis, oxygen would build up.
What is the purpose of having water tight covering?
What is the purpose of having a water-tight covering? They waxy cuticle keeps water inside the leaf cells. Tis water is then used for photosynthesis.
Which element of the cell theory has practical applications in health care because it promotes the use of sterilization and disinfection quizlet?
One element of the cell theory, which is practical applications in healthcare, is all cells come from pre existing cells. Yeah, because it promotes the use of sterilization and disinfection. We know that all cells come from pre existing cells created through the process of cell division.
What is the difference between the palisade layer and the spongy layer which is better at photosynthesis?
Moreover, palisade parenchyma has a large number of chloroplasts, while spongy parenchyma contains a low number of chloroplasts. Also, palisade parenchyma cells are tightly packed without the intercellular spaces, while the spongy parenchyma cells are loosely packed with a lot of intercellular spaces.
What are the differences between the palisade mesophyll and the spongy mesophyll?
Palisade mesophyll cells are elongate and form a layer beneath the upper epidermis, whereas spongy mesophyll cells are internal to the lower epidermis. Mesophyll cells in monocotyledonous leaves are often highly lobed.
What is difference between stomata and mesophyll?
The only way for gases to diffuse in and out of the leaf is though small openings on the underside of the leaf, the stomata. These stomata can open and close according to the plant’s needs. The tissues of the leaf in between the epidermal cells, into which gases diffuse from the stomata, are called mesophyll.
What is Calvin cycle in plants?
The Calvin cycle is a process that plants and algae use to turn carbon dioxide from the air into sugar, the food autotrophs need to grow. Every living thing on Earth depends on the Calvin cycle. Plants depend on the Calvin cycle for energy and food.
What are the holes in a leaf called?
Stomata (noun, “STO-mah-tah”, singular “stoma”) These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells.
Where does sunlight enter the leaf?
These are called palisade cells. They are tightly packed with many chloroplasts that trap the energy in sunlight for photosynthesis. spaces. These connect to the stomata on the underside of the leaf where the gases can enter and exit the leaf.
What is the difference between Sterilisation and disinfection?
Disinfection and sterilization are both decontamination processes. While disinfection is the process of eliminating or reducing harmful microorganisms from inanimate objects and surfaces, sterilization is the process of killing all microorganisms.
