What is the function of chloroplast in g1 phase in cell cycle?
The function of the chloroplast is basically to harvest light energy (which living organisms can’t use) and covert it into chemical energy (in the form of carbon-carbon bonds in ATP, glucose, etc.) via photosynthesis. During the G1 phase of the cell cycle, chloroplasts produce energy-rich molecules that: a) are directly used to make proteins (RNA transcription/translation) so the cell can: i) grow ii) prepare for DNA synthesis b) control gene expression, promoting expression of proteins involved in cell growth c) control the activities of proteins responsible for cell cycle progression, encouraging interactions that bypass G0 and lead to entrance into the S phase In order to proceed through G1, or the “growth phase”, of the cell cycle, the cell must first pass a “checkpoint” that is in place to make sure that cells don’t divide before they’re ready to or when they’re in unfavorable conditions. If conditions are unfavorable (i.e., the cell does not have enough energy to divide), it may
