Function of the wax cuticle in the leaf
It prevents water from evaporating
Function of the upper epidermis in the leaf
It’s thin and transparent to allow sunlight to enter the palisade mesophyll layer below.
Function of the palisade mesophyll layer in the leaf
Is column-shaped (increases surface area), tightly packed with chloroplasts to maximize photosythesis.
Where is amylase secreted from?
From the salivary glands and the pancreas.
Where is protease secreted?
In the stomach (pepsin) and from the pancreas (trypsin).
Where is lipase secreted?
From the pancreas and the small intestine.
Function of the colon
To absorb water from the digested food.
Where does chemical digestion of starch take place?
The mouth and the duodenum.
Where does the chemical digestion of maltose take place?
On the membranes of the epithelium lining of the small intestine.
Where does the chemical digestion of protein take place?
The stomach and duodenum
Where does the chemical digestion of lipids take place?
The duodenum
Why is lipid emulsification significant?
It is significant because it provides more surface area for the enzyme lipase to break down lipids into fatty acids and glycerol.
In which digestive juice(s) is amylase found?
Saliva and pancreatic juice.
What are the uses of carbohydrates made by plants in photosynthesis?
- In nectar
- Converted into starch to store energy
- Converted into cellulose to build cell walls
- Converted into sucrose to be transported in the phloem
- Glucose used in respiration to provide energy
