Please help fill in the blanks !!!
FrozenT [24]

Answer:

1. Chloroplast

2. cellular respiration

3. ATP

4. C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy

Explanation:

This question is describing the processes of photosynthesis and cellular respiration. Photosynthesis occurs in the CHLOROPLAST, which is responsible for the conversion of solar energy (from sun) into chemical energy (in glucose). The general photosynthetic reaction is:

6CO2(g) + 6H2O(l) + energy → C6H12O6(s) + O2(g)

Contrarily, the process of cellular respiration occurs in the MITOCHONDRIA. Cellular respiration involves the breaking down of food molecules to synthesize ATP (energy) for use during biochemical reactions. The general chemical reaction is as follows:

C6H1206(s) + 02(g) → CO2(g) + 6H20(I) + energy

For each of the following statements, indicate
stepan [7]

The plants that were allowed to self pollinate were the F1 plants.

The plants that are true breeding are P generation plants.

The plants where there were 3times as many tall plants as short plants are in F2 generation.

<h3><u>Explanation:</u></h3>

This question is based on the Mendel’s Experiment. Sir Gregor Johann Mendel was the father of genetics who experimented on garden pea plants <em>Pisum</em> <em>sativum</em> to see whether the characters got mixed or not and to know the real cause behind different traits of same character in plants.

He took the pure homozygous tall and short plants separately which he called as parental generation or P generation. These plants were homozygous, hence pure breeding.

As these plants were crossed between themselves, then the F1 generation showed all tall plants. This is because of the heterozygous plants which showed character of dominant trait. These plants were allowed to self pollinate.

As a result of self pollination of the F1 plants, the F2 plants were 75% tall in number whereas the other 25% short, which gave the phenotypic ratio of 3:1.
