|
|
They can produce their own oxygen.
|
|
|
They can receive nutrients through the cell wall.
|
|
|
They make their own glucose from sunlight during photosynthesis.
|
|
|
They use mitochondria to release energy from glucose during cellular respiration.

Detailed explanation-1: -Photosynthesis is the process that plants use in the presence of sunlight to convert carbon dioxide taken in by their leaves and water taken in through the roots to produce oxygen and sugar (glucose). This process takes place in the chloroplast of the plant cell with the presence of the green pigment of chlorophyll.
Detailed explanation-2: -Mitochondria produce energy through the process of cellular respiration. The mitochondria take food molecules in the form of carbohydrates and combine them with oxygen to produce the ATP. They use proteins called enzymes to produce the correct chemical reaction.
Detailed explanation-3: -In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.
Detailed explanation-4: -Both cellular respiration and photosynthesis involve carbon dioxide, oxygen, ATP, electron carriers, and water. However, cellular respiration produces energy for the cell, whereas photosynthesis produces glucose, or food for the cell.
