it is when the lettuce is bolting in the heat. It gets bitter. you gotta cut that part off and dunk it in cold water for a few min and then dry really well and put in your frige for a few days. if your fridge is not cold enough, turn the temp up. But if you just find it you can rinse it off and you can let it sit in the cool fridge. it is when the luttace becomes bitter and you can wash it well and dry well and set it in the fridge a few days to sweeten back up. Hope this helps.
Yes you would expect to see that.
Warm temperatures allow certain bacteria to multiply very fast. It depends what kind of bacteria are on the iceberg lettuce as to whether or not it would be dangerous. If the lettuce has been contaminated with pathogens, it could be dangerous whether or not it has been refrigerated.
Yes, they do have stems. Generally oranges or tangerines with stems can be found at an organic market.
One of the different types of stems is the Herbaceous stems. These are often found on annual plants. Ligneous stems are more woody, and often found on shrubs.

Listroderes costirostris is the scientific name of the lettuce root weevil. The insect in question may be found most often referred to with the common name vegetable weevil since attacks are not limited to just lettuce (Latuca sativa) but to almost 50 different edible plants in all. The pest will feed upon the entire plant indiscriminately or focus upon specific parts, such as leaves, roots, or stems.
Radishes are sometimes red and can be found in other colors. Their stems are always green.
Leafy vegetables are any variety of leafy plant that is cultivated for its leaves and stems to be eaten. Examples are lettuce, spinach and greens.
The job of cells found in stems is to uphold the stem and help to keep its shape. Cells also act as a stems "brain" telling it when to capture the correct amount ogf sunlight water and air.
Milky latex in the stems and leaves can be irritating to sensitized persons or animals, but the claim that poinsettias are deadly poisonous is greatly exaggerated.
