Answer:
Pteridophytes are vascular plants but they do not produce flowers and seeds which mean their source of reproduction is unknown or hidden.
On the contrary, Spermatophytes as the name indicates, are seed bearing plants. They produced seeds and flowers. Examples are flowering plants, cactus, leather flower, buttercup and may more.
Explanation:
The features or characteristics of organic compounds include:
1. They contain covalent bonds and are mostly non polar in nature
2. Have lower boiling and melting points than inorganic compounds
3. Many organic compounds are thermally unstable, They decompose into simpler molecules when heated at fairly high temperatures
4. Most organic compounds are inflammable and burn exothermically in sufficient air to yield carbon dioxide, water and heat energy.
5. Most organic compounds being largely non polar are insoluble in water.

Beets, carrots, turnips, onions, radishes, and (the odd one out) celeriac.
Cellular respiration uses oxygen to release the energy stored in food.
Explanation:
In breathing living organisms take oxygen and release the carbon dioxide it is similar to the aerobic respiration.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide!
