Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.
Why do plants need both chloroplasts and mitochondria quizlet?
Cells need both chloroplasts and mitochondria to undergo both photosynthesis AND cell respiration. After photosynthesis, which chloroplasts are needed for, which yields oxygen and glucose, plants need to break down the glucose and they use cell respiration to do this, which happens in the mitochondria.
Why are mitochondria essential for plants?
Mitochondria are the main sources of energy for each cell, and therefore for the plant as a whole. The process for converting raw nutrient materials into usable energy is known as cellular respiration. While energy production is the main function of the mitochondria, they also perform other services for a cell.
Why do plant cells need chloroplasts?
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. … The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. In the process of photosynthesis, plants create sugars and release oxygen (O2).
Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.
Why is mitochondria needed in photosynthesis?
Explanation: Photosynthesis is food production using the energy from sunlight. Chloroplasts are the organelles where photosynthesis occurs. Mitochondria are the organelles that convert the energy in food into ATP to be used as chemical energy by the cell.
What role does mitochondria play in photosynthesis?
Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. … They’re responsible for capturing light energy to make sugars in photosynthesis.
What are two main functions of chloroplasts?
Function of Chloroplasts
They are responsible to carry out photosynthesis, the process of conversion of light energy into sugar and other organic molecules that are used by plants or algae as food. They also produce amino acids and lipid components that are necessary for chloroplast membrane production.
Why do plant cells need chloroplasts and animal cells don t?
Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. … Once the sugar is made through photosynthesis, it is then broken down by the mitochondria to make Page 2 energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.
Does photosynthesis require chloroplasts?
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. … Chlorophyll A is the major pigment used in photosynthesis, but there are several types of chlorophyll and numerous other pigments that respond to light, including red, brown, and blue pigments.
What does chloroplast do in photosynthesis?
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.
How do chloroplasts perform photosynthesis?
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.
What does a mitochondria do?
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).
What are the two main functions of mitochondria?
Function. The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration and to regulate cellular metabolism. The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle.
What are 3 functions of chloroplast?
- Absorption of light energy and conversion of it into biological energy.
- Production of NAPDH2 and evolution of oxygen through the process of photosys of water.
- Production of ATP by photophosphorylation.
Why do plant cells have both chloroplasts and mitochondria and animal cells have only mitochondria?
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.
Do plant cells have mitochondria explain?
Explanation: Plant cells require mitochondria to produce energy for the cell, usually through photosynthesis during the day. When the sun sets and the energy from sunlight is lost, the plant continues on through the night producing energy through cellular respiration.
Is mitochondria in plant and animal cells?
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.
Do plants have chloroplasts?
Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
What do plants need for photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

What process occurs in the mitochondria?
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. … In ATP the energy is stored in the form of chemical bonds.
What will happen if chloroplasts are absent in the plant cells?
❀ If chloroplast is absent then the plant will unable to perform photosynthesis. … ❀ Therefore, if chloroplast is taken out of the cell, the green plant will not be able to carry out the process of photosynthesis which means the plant will die.
Why are mitochondria important to cells?
As the power plants in virtually every human cell (as well as animal, plant, and fungi cells), mitochondria play an essential role in creating energy to drive cellular function and basically all of our biological processes.
Why are mitochondria considered prokaryotic?
– Chloroplasts and mitochondria are prokaryotic. They have their own genes on a small, circular chromosome but no nucleus. This chromosome has little non-coding DNA, similar to those of bacteria. Chloroplasts and mitochondria also make some of their own proteins from their genes.
Does chloroplast produce ATP?
Chloroplasts and mitochondria are the major ATP producing organelles in plant leaves. … A comparison of OE and WT at the end of the night provide valuable information on the impact of higher ATP output from mitochondria on plant physiology, as mitochondrial respiration is the major source of ATP in the dark in leaves.
What is the structure and function of the chloroplast?
Chloroplasts are a type of membrane-bound plastids that contain a network of membranes embedded into a liquid matrix and harbor the photosynthetic pigment called chlorophyll. It is this pigment that imparts a green color to plant parts and serves to capture light energy.
Is mitochondria prokaryotic or eukaryotic?
No, prokaryotes do not have mitochondria. Mitochondria are only found in eukaryotic cells. This is also true of other membrane-bound structures like the nucleus and the Golgi apparatus (more on these later).
