|
They can produce their own oxygen.
|
|
|
They can make their own food from sunlight.
|
|
|
They can receive nutrients through the cell wall.
|
|
|
They use mitochondria to release energy from sugars
|
Detailed explanation-1: -The energy contained in these sugars is harvested through a process called cellular respiration, which happens in the mitochondria of both plant and animal cells.
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: -Furthermore, it is no surprise that mitochondria are present in both plants and animals, implying major commonalities in regulation, energy production, substrates employed, etc. This common presence of mitochondria, with similar functions and structure, underscores how close our life forms are.
Detailed explanation-4: -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-5: -Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
