Water is an essential to constituent of the protoplasm of living cells because it is directly involved in countless biochemical reactions like photosynthesis and respiration. Without it cells couldn’t move waste and by products, take in nutrients, perform intracellular transportation, functioning and signaling.
Answer:
Chloroplast
its function is to create chemical energy using light energy
Explanation:
Photosynthesis occurs in chloroplasts which can be compared to mitochondria because they both produce energy for the organism. The Chloroplast contains within it a pigment, chlorophyll which captures the sun's energy and turns into energy which is used to create other parts of photosynthesis. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis. Chloroplasts are one of the many organelles found in the body, and are generally considered to have originated as endosymbiotic cyanobacteria. In this aspect, they are similar to mitochondria but are found only in plants and protist.
Answer:
The combustion of fossil fuels such as coal and oil has raised the concentration of carbon dioxide in the atmosphere during the last century (CO2). This occurs because the combustion of coal or oil produces CO2 by combining carbon in the air with oxygen.
The lateral wall of the nasal cavity is formed partly by the maxilla, partly by the ethmoid bone, and partly by the perpendicular part of the palatine bone. Further back, where the nasal cavity becomes the nasopharynx, the lateral wall is formed by the medial pterygoid plate.
Answer:
It has four layers and attach with each other with desmosome.
Explanation:
The keratinocytes are arranged in four different layers which are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. These cells are attached with desmosome which is a membrane protein. The presence of these four layers made a barrier against damage done by heat, UV radiation, water loss, pathogens etc. There are fewer cells at the end of the time as compared to the start because may be of the water pressure on the membrane or these cells for a long time.
