Inessa05 [86]

Answer:

The correct answer is cell organelles.

Explanation:

A unique membrane-bound composition, which is found inside the eukaryotic cell's cytoplasm, that is, in plants and animal cells is termed as cell organelle. Some of the examples of cell organelles found within the cells of eukaryotes are endoplasmic reticulum, Golgi complex, mitochondria, chloroplast, etc.  

All these organelles play an essential function for the proper functioning of the cell, like chloroplasts found in plants play an essential role in the process of photosynthesis, and mitochondria both in plants and animals are regarded as the powerhouse of the cell.

NARA [144]

Answer: Peroxisomes

Explanation:

These are micro body which is found virtually in all the eukaryotic cells. They are involved in the catabolism of long chain and short chain fatty acid.

They generate the highly reactive oxygen species and it is broken down here only.These molecules are hydrogen peroxide and they are converted into water molecules.

This organelle is known as peroxisomes.

Ksenya-84 [330]

If a plant cell had a mutation such that the cyclic electron flow is observed at a much higher rate, which photosystem is most likely mutated such that energy is absorbed at a lower rate?

PSI

PSII

Answer:

PSII

Explanation:

Non-cyclic phosphorylation involves both PSI and PSII. The process starts with the splitting of water and excitation of electrons of the reaction center of PSII upon the absorption of solar energy at the wavelength of 680 nm. Any mutation in PSII would not allow the non-cyclic phosphorylation to occur when only cyclic phosphorylation would occur. The process of cyclic phosphorylation includes only PS I. Its reaction center absorbs maximum light at 700 nm and is cycled back while supporting ATP synthesis. Therefore, if a plant performs cyclic phosphorylation at a higher rate and absorbs less energy, this means that mutation was in PSII.
