Why all plant don't have chloroplasts?
Only cells which can get sunlight have chloroplasts. There is no purpose for others having it
What will happen if chloroplast is taken out of the cell and illuminated?
If chloroplast is taken out of the cell and illuminated then there will be no chlorophyll. Plants cannot make their own food .There will be no food for humans also.
What aré the products of chloroplast?
Chloroplasts are organelles found in plant cells and other eukaryotic organisms that conduct photosynthesis. Chloroplasts capture light energy to conserve free energy in the form of ATP and reduce NADP to NADPH through a complex set of processes called photosynthesis. ATP and NADPH energy is then used to produce sugar (glucose).
The basic equation of photosynthesis is:
6 H20 + 6 C02 + light >>> C6H12O6 + 6 O2
2 sets of reactions in photosynthesis are called light reactions and the Calvin Cycle.
The light reactions occur in the thylakoid membranes (granum) of the chloroplast. THe inputs are light and water and the outputs are ATP and NADPH needed to power the Calvin Cycle (previously known as dark reactions). In the light reaction water is split into oxygen and protons (hydrogen ions). Light powers the movement of the freed electron through an electron transport chain involving proteins embedded in the membrane. This includes the Photosystem II and Photosystem I complexes with pigments (such as chlorophyll) contained within the protein complex. NADPH is made from NADP and H+ at PSI. The proton byproduct of splitting water is pumped through another protein complex involving the enzyme ATP Synthase to produce ATP from ADP and Pi.
The Calvin Cycle occurs in the stroma of the chloroplast. Carbon dioxide, NADPH and ATP are the inputs and Sugar, NADP, ADP and Pi are outputs. ATP and NADPH provide the energy to drive a process of carbon fixation where the carbon in CO2 is combined with carbon from RuBP (5C molecule) and then via Rubisco enzymes processed into 3C molecules that are assembled into a 6C molecule (glucose).
THe glucose is used for the plant's own needs (cellular respiration) or processed into structural components such as cellulose for cell walls. Excess is stored as starch.
What do chloroplasts in a cell look like?
A chloroplast is a green cell, which gives the plant its green color. The cell wall surrounds an individual plant cell and is made up of fiber, and gives the plant its rigidity.
In what ways are mitochondria and chloroplast similar to some prokaryotic cells?
Prokaryotes are similar to green plants because, like plants, prokaryotes perform basic life functions, including reproduction, digestion, and respiration. As far as differences, prokaryotes have one cell, while green plants are multicellular. Plants are also eukaryotes—they have a nucleus.
Are chromosomes found in chloroplast?
DNA is in every part of the body... Not really true
It helps to look at it from two levels
Extracellular
Our body is made up of cells. Mitochondria is in all cells and is the energy system that keeps our cells running. DNA is also in all of our cells and offers the instructions for how our cells should grow based on our gene code and also the outside environment.
Intracellular.
Within our cells we have various structures. Mtiochondria (energy) Golgi apparatus (protein synthesis[muscle production]) cell nucleas (Director). DNA, contained within the cell nucleas, is the director. Mitochinria, although within every cell is in a separate intracellular structure to DNA. It's like it's a different department in the same company. So DNA isn't actually in mitochondria. It does however communicate to Mitochondria through messengers called mRNA or messenger RNA.
What is the importance of chloroplast to the cell?
Chloroplasts are important organelles in plant cells as they are responsible for photosynthesis, the process by which light energy is converted into chemical energy in the form of glucose. This energy is vital for the cell's metabolic processes and ultimately sustains life on Earth. Additionally, chloroplasts contain chlorophyll, a pigment that gives plants their green color and is essential for absorbing light energy.
Do carnivorous plants have chloroplasts?
Yes, the Venus fly-trap plant does have chloroplasts; even though it also eats insects it still produces food the way other green plants do, by photosynthesis.
What is the green pigment that is found in plants?
Chlorophyll in chloroplasts is responsible for the green pigment. The chlorophyll reflects green light.
Do both animal and plant cells have a chloroplast?
The purpose of chloroplasts is to create chlorophyll in a plant. Animals don't need to create chlorophyll so they don't have any chloroplasts in their cells.
Why do plant cells also need chloroplasts and mitochondria?
Chloroplasts are very important.They are responsible for photosynthesis.Mitochondria are important for respiration.
Why are chloroplasts present only in a plant cell not in an animal cell?
The chloroplast helps with photosynthesis (making the plant green). The cell wall covers the chloroplast cell. Animals don't need to turn light into food (photosynthesis) so they don't need the cell wall and the chloroplast. Animal cells do not have a cell wall because, if we had cell walls then we would stand straight up and it would be like our spine couldn't bend.
What chloroplast and mitochondria contain their own genetic information in form of?
Both chloroplasts and mitochondria have their own sets of chromosomes composed of DNA.
Why do human cells don't contain chloroplasts?
Animals dont have chlorolplasts because one we are not plants and two we have evolved in a way that we never needed to perform photosynthisis our cells make enough ATP with the mitocondria already.
In what organ of a plant would you find chloroplasts?
A plant's chloroplasts are found in the plant cells.Trust me, this answer is correct.I'm doing science homework right now and i saw this question.I had this question about a month ago because i had a project.Believe me,it's right.I'm looking at it right now in my book.
Do photosynthetic plants have mitochondria and chloroplasts?
Almost all plants have mitochondria. Plants use these mitochondria to release the energy from the glucose that is stored inside them (The glucose is obtained via Photosynthesis).
The light dependent reactions take place inside chloroplast in stacks of?
Grana are stacks of thylakoids.
The parts of a chloroplast that holds chlorophyll are called?
I'm pretty sure the thylakoids in the chloroplasts probably hold in the energy for the plant. That's what I think. Sorry, I'm just a 7th grade student looking for what you're looking for.

How are solar panels and chloroplasts similar?
Solar Cells and chloroplasts are similar by absorbing the energy of the sun. Then it changes into energy, which powers the house electricity.
A chloroplast is a miniature "solar collector," transforming light energy into chemical energy through photosynthesis. The green color of the disks is due to the presence of a pigment called chlorophyll that reacts with light.
they both make plants live
so that people know hoe solar energy has been used.
How many chloroplasts are present in a leaf?
There is no exact number.There are thousands of chloroplasts.
Why can't plants live without chloroplasts?
There are some plants that have foresaken the use of chlorplasts by resorting to a life as a decomposure, that is living off of the decaying remains of other living things. One such a plant is 'Dead Man's fingers'. Predacious plants (Venus Fly-trap, Sundew, Bladder-wort, Pitcher Plant) could conceivably do without sunlight as an energy source and take to living solely off of the prey they catch. However none of them have abandoned their photosynthesis just yet - after all if the energy is there why not take advantage of it. Other energy source a plant could conceivably abandon light for would be heat and chemical sources - however these are already heavily exploited by bacteria and Archea and a plant would be hard pressed to invaded into realms already claimed by the worlds most efficent organisms.
