What is a chloroplast, for example?

A chloroplast is a plant component that contains chlorophyll and performs photosynthesis. A chloroplast is a cell in algae that eats carbon dioxide and emits oxygen while producing sugar. Noun. Plural form of chlorophylum.

Chloroplasts are the greenish-yellow color found in plants that perform photosynthesis. They contain most of the plant's food reserves and produce carbohydrates through the process of photosynthesis. Humans also use chloroplasts as a model to understand how cells work because they are similar in many ways to human cells. For example, both chloroplasts and mitochondria are called "organelles" that contribute to cellular metabolism by generating energy molecules used by all organisms. However, whereas mitochondria are only found in higher organisms such as humans, chloroplasts are present in almost all living organisms from bacteria to plants and even some single-celled organisms like algae.

Chloroplasts originated about 2 billion years ago when ancient bacteria began using sunlight to synthesize their own food sources. The ability to make their own proteins using the same mechanisms we use has led scientists to compare chloroplasts to mitochondria because both contain their own DNA (but not always in the same amount).

What do chloroplasts need to survive?

A chloroplast is a green organelle found in the cells of various eukaryotes such as plants and algae. It is in charge of photosynthesis, which is the mechanism by which the organism obtains the energy it requires to exist. A chloroplast uses light energy to produce sugar from carbon dioxide (CO2) and water (H2O). The chemical reaction that takes place inside the chloroplast is called photosynthesis.

Chloroplasts are very similar to mitochondria: they are both membrane-bound bodies that contain their own DNA. However, whereas the mitochondrion is responsible for generating energy for the cell, the chloroplast performs a different role. Chloroplasts receive nutrients from the nucleus via stroma membranes and then conduct these materials into other parts of the cell using their own internal structure and protein make-up. This process allows the cell to divide its resources between itself and another organism. For example, a plant can make seeds and leave them in nature, or it can make flowers or fruits to be eaten by animals that come to harvest them.

In addition to being responsible for photosynthesis, the chloroplast contains many other important functions within the cell. For example, it controls the number of cells that divide per seed or fruit, it determines how big the seed or fruit will grow, and it signals when the plant has enough food for growth vs. reproduction. The chloroplast also contains enzymes that allow the plant to detoxify chemicals present in pesticides and other pollutants.

Does chromoplast take in carbon dioxide?

Chloroplasts are photosynthesising organelles found in plant cells and eukaryotic algae. Chloroplasts collect sunlight and utilise it, together with water and carbon dioxide gas, to create nourishment for the plant. They are also where photosynthesis occurs. During photosynthesis, light energy is converted into chemical energy that can be used by plants for growth and cellular division. The main product of this process is glucose, which becomes stored in the form of starch inside the cell walls of the leaves and other organs of the plant.

In addition to storing carbohydrate, plants use their chloroplasts to make essential oils, proteins, and hormones. They also have a role in disease resistance and environmental adaptation. Humans eat vegetables, fruits, herbs, and spices because of their beneficial effects on health. These benefits come from the natural chemicals called phytochemicals that are produced by plants as a means of self-defense against harmful organisms such as bacteria and viruses. Some phytochemicals have strong anti-cancer properties; others protect against heart disease and diabetes. Many come from fruit and vegetables but some are found in whole grains, beans, nuts, and seeds.

When plants die back they shed their old leaves and branches which can provide nutrients for new shoots if they are left in place. This is called "biofertility" and it has two advantages for farmers.

Is it possible to find chloroplast in photosynthetic protists?

They are comparable to mitochondria in this regard, but are exclusively present in plants and protista. Mitochondria are known as powerhouses of a cell because they generate energy for cells by using oxygen and nutrients from the food we eat. They are also responsible for many other cellular functions including cell division, cell signalling, cell growth and even programmed cell death.

Photosynthesis is the process by which organisms such as plants convert light energy into chemical energy through the synthesis of glucose from atmospheric CO2 and water. This conversion requires several different proteins contained within the chloroplast. Proteins imported into the chloroplast are targeted to specific locations within the organelle using unique coding sequences called targeting signals. These signals are found on the amino acid sequence of the protein itself; they are usually located either in the amino or carboxy terminal regions of the protein. The signal is recognized by receptor proteins that locate them on the outer surface of the envelope surrounding the organelle. Once bound to the receptor, the signal is passed onto other proteins which cause the membrane of the envelope to fuse with that of the organelle, allowing the protein to enter. Inside the chloroplast, its location will determine what role it plays in the life cycle of the plant.

What is the role of chloroplasts in algae?

Chloroplasts are photosynthetic cell organelles found in algae that may transform solar energy into chemical energy via a photosynthetic mechanism. Chloroplasts are similar to plant cells' mitochondria, which also function in generating energy for cells but are not responsible for protein synthesis as the nucleus does. Algae are single-celled plants that lack roots and vascular tissues; they derive their nutrients from the atmosphere and sunlight. Most algae are not useful for food or industry because they cannot be cultured outside of their natural habitat. However, some species are used in biotechnology and biofuels research.

Algae can absorb carbon dioxide from the air and water and use it as fuel to produce energy within their cells. They do this by combining carbon dioxide with hydrogen molecules from water to create organic compounds that become their cellular material. These compounds may then be converted into oil or sugar, which can be used for energy or built into living organisms. Some species of algae can capture energy from light waves and use it for the same purpose as plants: building up their own organic material. Others obtain all their energy from the reaction of water with oxygen gas dissolved in them. Still others have lost the ability to make their own food and must find it elsewhere.
