Answer:
The carbohydrates will not be digested properly.
Explanation:
The kind of carbohydrates that a person takes from plants is in the form of amylose. From animals, a person will receive carbohydrates in the form of glycogen,
The digestion of carbohydrates begins as soon as the food is taken in the mouth by the amylase enzyme present in the saliva.
If a person does not have the salivary glands, then there will be no production of saliva and amylase enzyme. Hence, the carbohydrates will not be digested.
Answer:
Photosynthetic autotroph
Explanation:
Plants, algae/seaweed and some bacteria can use photosynthesis to turn light energy, carbon dioxide and water into glucose and oxygen. The glucose, or sugar becomes the food for these organisms.
Since they can produce their own food, they are called producers, but they are also called autotrophs. "Auto" meaning self, and "troph" meaning nutrition. Therefore, the correct choice is: Photosynthetic autotroph.
Answer:
Bryophytes, lycophytes, ferns, whisk ferns, and horsetails. (Ans. A)
Explanation:
Seedless vascular plants: They are defined as the plants which contains developed specialized tissues known as vascular structure for transportation of nutrients and water. They are known as higher plants because they include from flowering plants to conifer trees (growing seeds) to fern (do not grow seeds).
Seedless vascular plants are divided into four plant divisions:
1) Psilophyta
2) Lycophyta
3) Sphenophyta
4) Pterophyta
Seedless vascular plants includes horsetail and clubmosses, these plants are not producing flowers or seeds. Spores of these plants are very lightweight with the help of this they are disappearing quickly in the wind.
