Chloroplasts

Chloroplasts originated from a process called endosymbiosis, where a eukaryotic cell engulfed a photosynthetic cyanobacteria. Over time, a symbiotic relationship developed where the cyanobacteria became integrated into the cell and evolved into what we now recognize as chloroplasts. This event is believed to have occurred around 1.5 billion years ago, contributing to the evolution of photosynthetic organisms.

Chloroplasts tend to be located near the periphery of plant cells due to their need for light in order to carry out photosynthesis. Placing chloroplasts closer to the cell membrane allows for more efficient absorption of light energy. Additionally, this positioning helps prevent shading of chloroplasts by other cellular structures and maximizes their exposure to sunlight.

Yes. The outer membrane is similar to modern eukaryotic membranes, such as the plasma membranes of animals and plants. The inner membrane is similar to modern prokaryotic membranes, found in bacteria. This difference has been taken as one piece of evidence to support the theory of the endosymbiotic origin of these two organelles, i.e. the idea that each of these organelles formed originally from the engulfing of a prokaryotic cell by a eukaryotic one.

The green pigment in chloroplasts is chlorophyll. Chlorophyll is responsible for absorbing light energy during photosynthesis, which is the process by which plants convert sunlight into chemical energy.

Photosynthesis occurs in the chloroplasts, where sunlight is converted into chemical energy in the form of glucose. This process is essential for plants to produce their own food and release oxygen into the atmosphere.

Chloroplasts and mitochondria contain genetic information in the form of circular DNA molecules. These DNA molecules encode for a small number of genes that are involved in the functioning of these organelles.

Chloroplasts are organelles found in PLANT CELLS and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb light and use it in conjunction with water and carbon dioxide to produce sugars, the raw material for energy and biomass production in all green plants and the animals that depend on them, directly or indirectly, for food. 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. It is derived from the Greek words chloros which means green and plastwhich means form or entity. Chloroplasts are members of a class of organelles known as plastids.

Chloroplasts are typically green due to the presence of chlorophyll, a pigment necessary for photosynthesis. The green color arises from chlorophyll absorbing red and blue light while reflecting green light.

chlorophyll.. comes from the greek word meaning ''green leaf''. Chlorophyll was first isolated br french chemist JOSEPH PELLELIER ang his research assistant BIENAIME CAVENToU.

Thylakoid membranes are an essential part of chloroplasts where the light-dependent reactions of photosynthesis occur. They contain chlorophyll molecules that capture light energy and convert it into chemical energy to produce ATP and NADPH.

Chloroplasts are responsible for photosynthesis in plant cells, where they convert light energy into chemical energy stored in glucose. They contain chlorophyll, a pigment that captures light energy and initiates the process of photosynthesis. Chloroplasts also produce oxygen as a byproduct.

Chloroplast is an organelle found in plants and algae cells where photosynthesis occurs.

The chloroplast contains chlorophyll which is the light sensitive pigment that powers photosynthesis and other pigments. Chlorophyll gives the plant its green color

A plastid containing chlorophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements. In animals chloroplasts occur only in certain low forms.

Chloroplasts are what give plants their green color.

Organelle that makes sugars, using carbon dioxide, water, and the energy from sunlight.

Cholorplasts can be found in plant cells and produces food.

It is an eukariyotic organelle. It is important for photosynthesis

The chloroplast is a cell organelle found in plant cells that is responsible for photosynthesis, a process that generates energy for the plant using sunlight. Inside the chloroplast, chlorophyll, a pigment that gives plants their green color, captures light energy and converts it into chemical energy in the form of sugars.

Paul Berg is often referred to as the father of modern biotechnology. He pioneered the development of recombinant DNA technology in the 1970s, which allowed researchers to manipulate and recombine DNA from different sources, leading to significant advancements in the field of biotechnology.

Chloroplasts contain chlorophyll, which is a pigment that captures sunlight for photosynthesis. They also contain thylakoids, which are membrane-bound compartments where light reactions of photosynthesis occur. Additionally, chloroplasts house enzymes and other molecules necessary for the overall process of photosynthesis.

The semi-fluid matrix within the chloroplast is called the stroma. It plays a key role in the light-independent reactions of photosynthesis, where enzymes and other proteins are located to help facilitate the process of converting carbon dioxide into carbohydrates.

No, roots do not have chloroplasts. Chloroplasts are typically found in plant leaves and are responsible for photosynthesis, which is the process of converting sunlight into energy for the plant. Roots are mainly responsible for absorbing water and nutrients from the soil.

No, animal cells do not have chloroplasts. Chloroplasts are organelles found in plant cells and some protists, where they are responsible for photosynthesis. Animal cells obtain energy through other organelles like mitochondria.

Chloroplasts appear green because of the pigment chlorophyll, which absorbs blue and red light for photosynthesis and reflects green light. This reflection of green light is what gives chloroplasts their green color.

The green colored chemical that traps light is called Chlorophyll.

Water is absorbed by the roots from the soil and transported up to the leaves through specialized tubes called xylem. This process, known as transpiration, creates a pull that helps draw water up the plant. Once in the leaf, water is used in photosynthesis to produce oxygen and glucose, essential for the plant's growth and survival.

Photosynthesis takes place in the chloroplast, where light energy is converted into chemical energy in the form of glucose. This process involves capturing sunlight, absorbing carbon dioxide, and releasing oxygen as a byproduct. It is essential for plants to create their own food and is the basis of the food chain on Earth.

It is a matter of the structure of the plant cell and the use of them. Plants need chloroplasts to absorb light and use it in conjunction with water and carbon dioxide to produce sugars, the raw material for energy production in all green plants. Animals cannot do that. It is where photosynthesis takes place. there they produce energy (ATP), they reduce NADP to NADPH through a complex set of processes.
