Gross motor skills involve large muscles in the arms legs and torso. The general guidelines for gross motor development for children 4 years of age include running, jumping and climbing well and control their direction. They can hop on one foot and they start to skip at this age. At this stage, they are also able to ride a tricycle and reliably catch a ball. 

The answer to your question is 4.

Answer:

Photosynthesis is the process in which cells use carbon dioxide and water to make glucose in the presence of sunlight.

Respiration is the process in which glucose molecules are utilized to release energy in the form of ATP.

Explanation:

Ans1- Respiration in cells occurs in mitochondria.  Cells gain energy in the form of ATP. Conversion of glucose in the form of ATP is known as cellular respiration.

Cellular respiration can take place either in presence of oxygen(aerobic respiration) or in absence of oxygen(anaerobic respiration ).

Before entering into cellular respiration glucose molecule has to be converted into pyruvic acid. This process in known as GLYCOLYSIS.

<em><u>Anaerobic respiration</u></em> occurs in mitochondria when oxygen is not present. It is known as fermentation.It is not effective process to produce ATP from glucose as in this process only 4 ATP can be released.  

<u><em>Aerobic respiration</em></u> occurs in mitochondria in presence of oxygen.  This is effective pathway to gain ATP as it releases 36 ATP from 1 glucose molecule.

Ans2- All cells which has photosynthetic pigments are able to use photosynthesis. Example- Blue green algae, cynobacteria etc.

Ans3- We can see different shades of green colors of plants and leaves because of different types of chlorophyll present in plant. Chlorophyll are of 6 types in plant. Their types are based on the lights they absorb. Two main types of chlorophylls are chl a and chl b.

Ans4- Both plant and animal cells have mitochondria. In plant also they need energy. To get ATP from breakdown of glucose respiration is occur in plant also.

Ans5-In photosynthesis glucose is formed from water and carbon di oxide. 6 carbon dioxide and 6 molecules of water are used to make 1 molecule of glucose. Water and carbon di oxide are reactant in this process.

Ans6 -  Cells without oxygen can burn glucose to release energy. This process is known as Anerobic respiration/ fermentation. But the outcome of energy is lower than aerobic respiration. ( ANS1)

Ans7- In the process of photosynthesis reactants are water and carbon di oxide. Oxygen produced released in the form of gas along  with carbon di oxide.

Ans8- The enzymatic reaction of respiration occurs in mitochondria. Krebs cycle occurs in the matrix of mitochondria.( ETC electron transport chain) to release ATP occurs in cristae of inner membrane of  mitochondria.

Ans9- Plants make glucose through photosynthesis . In  presence of sunlight plants use carbon dioxide and water to make sugar.

What is one role of ATP in the light-independent reaction of photosynthesis?
azamat
Adenosine Triphosphate is a compound used by the cell to store energy. Together with NADP, ATP is responsible for carbon dioxide reduction. Carbon dioxide is said to be reduced when it loses oxygen, reacts with hydrogen or gains electrons. Carbon dioxide becomes part of Glycerate 3-phosphate.
