What happens to carbon dioxide and water in chloroplast?
In chloroplasts, carbon dioxide and water undergo photosynthesis to produce glucose and oxygen. This process is powered by sunlight and occurs in the presence of chlorophyll, a pigment in chloroplasts. The glucose produced is used as energy for the plant, while the oxygen is released as a byproduct.
Are there chloroplasts in subsidiary cells?
Subsidiary cells do not typically contain chloroplasts. Chloroplasts are found in the guard cells of plant stomata, where they play a role in regulating gas exchange. Subsidiary cells primarily function in supporting and assisting the guard cells in their role in controlling stomatal opening and closing.
Why are chloroplasts considered carbohydrate factories and ribosomes as protein factories?
Chloroplasts are considered carbohydrate factories because they use light energy to convert carbon dioxide from the air into carbohydrates through the process of photosynthesis. Ribosomes are considered protein factories because they are the cellular organelles responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.
What is the Process that occurs in chloroplasts is called what?
The process that occurs in chloroplasts is called photosynthesis. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose molecules, using carbon dioxide and water. This process is essential for the survival of most living organisms on Earth.
Why do plant cells need chloroplast and vacuoles?
A plant cell needs water to maintain it's shape. Unlike animal cells, plants cannot suffer hydrolysis, meaning plants cannot burst when they fill up with water. This is due to the cell wall, and plant cells instead experience turgor pressure. This creates the need for a large vacuole to hold the needed water. If the cell were to not have enough, the cell would atrophy (flatten) and become flaccid.
Is chloroplast a living structure?
Yes, chloroplasts are living structures found in plant cells. They are responsible for photosynthesis, converting sunlight into energy for the plant.
What are the functions of chloroplast and mitocondria?
Are the power plants that produce energy for important life processes in the animal cell and are responsible for cellular respiration.
Chloroplast is a structure in plant cell. They are filled with chlorophyll, which uses Sun's energy to combine water, carbon dioxide, and nutrients from the soil into sugar. This is the process of photosynthesis. Chloroplast is only found in plant cell.
No, a chloroplast is not an organ. It is a specialized organelle found in plant and algae cells that is responsible for photosynthesis, the process of converting light energy into chemical energy to produce sugars. Organs are made up of tissues and perform specific functions within an organism's body.
A) flagella are cellular structures associated with movement in unicellular organisms. They are long, whip-like structures that help propel the organism through its environment. Vacuoles are membrane-bound sacs that store materials and assist with cell structure and shape. Ribosomes are involved in protein synthesis. Chloroplasts are organelles involved in photosynthesis and are typically found in plant cells.
When did Julius Von sachs discover chloroplast?
Julius von Sachs discovered chloroplasts in plant cells in 1882. He noted their green color and role in photosynthesis, paving the way for further research into plant physiology.
Does the Hulk have chloroplast in his cells?
No. The Hulk is green because he has gamma rays surging through his blood, which the director assumes is green. This comes from the original Marvel Comics where he depicted like this.
Chloroplast is found on earth as part of the plant cell, and used to synthesis glucose from CO2 and H2O using energy from sunlight
What are the similarities between mitochondria an chloroplast?
Both mitochondria and chloroplasts are organelles. Mitochondria are used in cellular respiration and chloroplasts are used in photosynthesis. Photosynthesis and cellular respiration are opposite processes. Both are believed to have evolved from a living single celled bacteria that was engulfed by an early form of a plant or animal cell. Therefore, both mitochondria and chloroplasts have their own DNA. Furthermore, they both have free ribosomes.
NOTE! they both DO NOT have 2 membranes. chloroplasts have 3 membranes
No, chloroplast is not a liquid. Chloroplasts are membrane-bound organelles found in the cells of plants and some algae, responsible for photosynthesis and containing chlorophyll pigments. They are typically described as semi-fluid structures within the cell.
What role do chloroplasts play in plant cells?
Chloroplasts are responsible for photosynthesis in plant cells, converting sunlight into energy for the plant. They contain chlorophyll, a pigment that captures light energy and uses it to produce glucose from carbon dioxide and water. This process is essential for plant growth and survival.
Flat discs inside chloroplasts arranged in stacks?
These are thylakoids, which contain chlorophyll and are the sites of photosynthesis in chloroplasts. Thylakoids are arranged in stacks known as grana, where light reactions of photosynthesis occur.
Why is it useful for there to be a large amount of chloroplasts in the guard cells?
Guard cells regulate the opening and closing of stomata to control gas exchange and water loss in plants. The high concentration of chloroplasts in guard cells is important because it enables them to perform photosynthesis, producing the necessary energy to actively pump ions and regulate water movement, ultimately influencing stomatal aperture.
Chloroplasts are found only in organisms that are able to -?
Chloroplasts are found only in organisms that are able to undergo photosynthesis. This process involves converting light energy into chemical energy to produce food. Plants, algae, and some types of bacteria have chloroplasts.
Are chloroplasts able to kill certain plants?
No, a chloroplast is an organelle found in plant cells that gives them the ability to photosynthesize and respire. They do not kill plants, nor are they a pesticide, they give them the ability to live.
What would happen if a plant did not have chloroplast?
The plant would die. Chloroplast turns light into energy and without energy the plant would eventually die.
Thin sack found inside chloroplast that contains chlorophyll?
The structure you are referring to is likely the thylakoid membrane, which forms a stack-like structure called a grana within the chloroplast. Chlorophyll molecules are embedded in the thylakoid membrane and are responsible for capturing light energy during photosynthesis.
Why do plants need chloroplast and the animal cells don't need it?
Plants need chlorophyll because that is what allows them to convert sunlight to energy they can use in their metabolism. People do not use chlorophyll, and so don't have it, because as animals we do not convert sunlight directly to energy. We eat plants, or other animals that eat plants, and use their energy.
Why do plants have mitochondria and chloroplast?
All plant cells have mitochondria to serve as the cell's powerhouse. Without the mitochondria in a plant cell, the cell won't be able to do its functions. Mitochondria is a complex part of cell. Chloroplast is another important organelle of a plant cell. Animals can survive without chloroplast but plants don't. Plants have chloroplasts to be able to manufacture their own food. The chloroplast traps light coming from the sun. And the light energy is a very much important ingredient of photosynthesis.
Do muscle cells have chloroplast?
No, muscle cells do not have chloroplasts. Chloroplasts are found in plant cells and some protists, where they are responsible for photosynthesis. Muscle cells generate energy through other organelles, such as mitochondria.
