pashok25 [27]

Answer:

Option A, Start the reaction by absorbing light energy

Explanation:

Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.

Hence, option A is correct.

Savatey [412]

Answer:

In compare to eukaryotes,prokaryotes are morphologically simpler,more evolutionary primitive,less sensitive to physical environment.

Explanation:

Prokaryotes are unicellular organism which don't possess cell organelle like nucleus,mitochondria,Endoplasmic reticulum,golgi body, etc.

They are the first living organism in the primitive earth and the genetic components are located in the cytoplasm which is enclosed by cell membrane.

prokaryotes contain 3 domains that are Archaea, bacteria and eukarya.

The cytoplasm is enclosed by cell membrane.

Molecular studies have reveal that eukaryotes are evolved from prokaryotes.

Some prokaryotes bear long projection which helps them for locomotion,called as flagellum.This is present in gram positive and gram negative bacteria.
