Five substances that plant makes from glucose are energy, starch, cellulose, fat and protiens.
What is the use of glucose made by photosynthesis ?
In plant cells, the respiration mechanism can use glucose as a substrate and break it down. The plant can utilise the chemical energy created during respiration for cellular processes like protein synthesis or cell division.
The complex carbohydrate starch can be created by linking thousands of glucose molecules together. Plant cells store starch in the form of grains.
The complex carbohydrate cellulose can be created by the linking of thousands of glucose molecules. Plant cells' cell walls are made of the extremely durable chemical cellulose.
Sugar can be changed by plant cells into fat, a different kind of molecule that stores energy.
Plant cells can also combine nitrates and sugars to produce aminoacids, which they subsequently use to build proteins.

Answer:
Explanation:
You have external defense systems, which include your skin, tears, mucus, saliva, stomach acid, cilia (small hairs) and helpful bacteria. ... The skin stops pathogens from entering the blood, at least when you're not bleeding. The tears, mucus, and cilia trap them and help push them back out of your body.

B. They decrease the rate of the chemical reactions involved in digestion
C. They increase the rate of the chemical reactions involved in digestion
D. They aid in the process of moving food more quickly to the stomach
E. They are consumed as part of the chemical reactions involved with digestion
Answer:
the answer is C) They increase the rate of the chemical reactions involved in digestion
Explanation:
The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
Answer: (c)
Explanation: they melt down the food chemicals into a not very pretty clump of siliava and chewed up food which is not slowing down, it is speeding up.
b. egg and sperm cells
c. gametes that are identical
d. four identical nuclei
Answer:
The flow of energy in the ecosystem is generally unidirectional and there is loss of energy across each trophic levels successively.
Explanation:
The entry of energy occurs in the form of sunlight which is process by the plant through photosynthesis resulting in formation of nutrient essential for survival of plants. This plant energy then moves to the living organism feeding on it such as primary consumer. Here most of energy is used up and some energy is lost as heat. Likewise in the case of secondary consumers and tertiary consumers energy is used up with loss of some energy as heat at each level. The energy flow is unidirectional in the sense that it cannot be used back by the plant from the consumer levels. Thus the energy flows successively with loss at each level as heat.
B) It breaks down food particles.
C) It encloses the cytoplasm.
D) It produces proteins.
