Problem : 
What are the basic differences between the shoot and the root?
The root is the portion of a plant beneath the soil.  It brings in essential 
water and minerals from 
the soil and anchors the plant to the substrate.  The shoot, on the other hand, 
includes all aerial 
plant structures such as stems, leaves, flowers, and fruits.  It gathers the 
carbon dioxide and light 
energy necessary for photosynthesis, provides surfaces for gas exchange, and 
contains the 
plant's reproductive organs.
 
Problem : 
What are the ingredients and products of photosynthesis?  What are organisms 
that produce their own food through photosynthesis called?
In the process of photosynthesis, the plant converts water, carbon dioxide, and 
light energy into 
oxygen, sugars, and more water.  Organisms that produce their own organic 
nutrients are called 
autotrophs.
 
Problem : 
In the life cycle of plants, what is the multicellular diploid stage called?
The sporophyte
 
Problem : 
Where are jacket cells located and what is their function?
A layer of jacket cells covers the reproductive organs of terrestrial plants.  
Their function is to 
protect the sex organs (and gametes) from drying out in a terrestrial 
environment.
 
Problem : 
How do plants regulate water loss during gas exchange?
The stomata in the epidermis of leaves, through which gas exchange 
occurs, can open 
and close to prevent excessive evaporation of water into the environment.
