Does phloem transports water and minerals?

No, phloem is a type of vascular tissue in plants that is responsible for transporting organic nutrients, such as sugars and amino acids, produced during photosynthesis. Water and minerals are transported through the xylem, another type of vascular tissue in plants.

Does photosynthesis take place only in the chloroplast?

Neither of those processes require chlorophyll; especially respiration. It should be noted, however, that chlorophyll is commonly used to absorb light during photosynthesis in plants. While there are some archae and bacteria that can perform photosynthesis without chlorophyll, it is used in virtually all plants.

What plants do bacteria eat?

Bacteria can eat a variety of plants, including cellulose-rich materials like grass, leaves, and wood. Some bacteria can also consume sugars or starches produced by plants as part of their metabolic processes. Each species of bacteria has specific preferences for the types of plant material they can break down and use as a food source.

What cell contain the most chloroplast?

Guard cells, located in the epidermis of leaves, contain the most chloroplasts per cell. They are responsible for controlling the opening and closing of leaf stomata for gas exchange and contribute to photosynthesis.

Are chloroplasts present in mosses?

Yes, mosses do contain chloroplasts. Chloroplasts are the organelles responsible for photosynthesis, where they convert sunlight into energy for the plant. In mosses, chloroplasts are usually found in the green leaf-like structures called gametophores.

What is the chloroplast nickname?

The word chloroplast is derived from the Greek words chloros, which means green, and plast, which means form or entity. Chloroplasts are members of a class of organelles known as plastids.

A model chloroplast

Chloroplasts are one of the many different types of organelles in the cell. In general, they are considered to have originated as endosymbiotic cyanobacteria (previously known as blue-green algae).

What would be most likely to happen to a plant that had working chloroplasts in its cells but had taken in a poison that kept mitochondria from working?

The plant would not be able to produce ATP through cellular respiration, but could still generate energy through photosynthesis. It would likely experience reduced growth, as ATP is essential for many cellular processes. However, as long as photosynthesis continues, the plant would have an alternative energy source to support its survival, albeit at a slower rate.

What do chloroplasts do for pant cells?

Chloroplasts are responsible for photosynthesis in plant cells, converting light energy into chemical energy in the form of glucose. They contain chlorophyll, the pigment that absorbs sunlight and initiates the process of photosynthesis. Chloroplasts also produce oxygen as a byproduct of photosynthesis.

What does stroma refer to?

== == Stroma is the thick fluid within the chloroplast.
I think you mean 'Stroma'. Stroma can refer to two things in Biology. Stroma is the fluid inside chloroplasts, the site of photosynthesis in all plant cells. It is also, however, the framework (like a skeleton) inside any biological tissue, cell or organ.

What is the function of the chloroplast in a short answer?

The chloroplast is a specialized organelle found in plant cells that is responsible for photosynthesis, the process by which plants convert sunlight into energy in the form of glucose. Chloroplasts contain chlorophyll, a green pigment that captures light energy needed for photosynthesis.

How do photons interact within chloroplasts?

Photons are absorbed by pigments within chloroplasts, such as chlorophyll, which then excite electrons to a higher energy state. These energized electrons are then used in photosynthesis to convert light energy into chemical energy, leading to the production of ATP and NADPH. Ultimately, this energy is utilized to drive the synthesis of carbohydrates in plants.

What is the garbage house of cell?

The garbage house of a cell is the lysosome. It is responsible for breaking down cellular waste, old organelles, and foreign substances through the process of hydrolysis. The lysosome contains enzymes that help in the degradation and recycling of cellular components.

Which kingdom does not move or contain chlorophyll and therefore cannot make their own food?

The Fungi Kingdom does not move or produce chlorophyll, so they cannot make their own food. They feed off of other\ things. For example, mold grows on foods and feeds off of that food.

What does chloroplasts do for leaves?

Chloroplasts are responsible for photosynthesis in plant cells, where they convert sunlight, water, and carbon dioxide into glucose and oxygen. This process provides energy for the plant to grow and carry out its functions. Chloroplasts also give leaves their green color due to the presence of chlorophyll pigments.

Why are cell walls and chloroplasts present in plant cells?

For the cell wall, it is present in the plant because it functions is to keep the cell its shape.

Example: leaf - it has its shape because it has cell wall.

For the chloroplast, it is present in the plant cell because it functions is to trap sunlight for the plant to photosynthesize.

Example: leaf - it makes food for the plant with the help of the chloroplast

What was the significance of the development of chloroplasts?

The development of chloroplasts was significant because it allowed plants and algae to perform photosynthesis, converting sunlight into energy. This process not only provides these organisms with energy, but also produces oxygen as a byproduct, which is essential for life on Earth. Furthermore, chloroplasts are believed to have originated from an endosymbiotic relationship between ancient bacteria and early eukaryotic cells, contributing to the evolution of complex life forms.

What is chloroplast and xylem?

Chloroplast is a specialized organelle found in plant cells where photosynthesis occurs. It contains chlorophyll, a green pigment that captures light energy to produce glucose from carbon dioxide and water.

Xylem is a vascular tissue in plants that transports water and nutrients from the roots to the rest of the plant. It consists of specialized cells called tracheids and vessel elements that form long tubes to facilitate the upward movement of water.

What is chloroplasts equation?

Chloroplasts do not have an equation, as they are organelles found in plant cells responsible for photosynthesis. During photosynthesis, chloroplasts convert sunlight, carbon dioxide, and water into glucose and oxygen, utilizing the energy from sunlight to produce food for the plant.

Why do bryophytes require a moist environment for sexual repoduction?

when the fern spore falls to the ground, it doesn't begin to grow fronds right away. Instead, the spore grows into a tiny heart - shaped plant called a prothallium. The prothallium does not look like a fern frond at all. If you observe closely, you may find prothallia growing in damp, shady places where there are ferns.

Does spirogyra have chloroplast?

Yes, Spirogyra has chloroplasts. These chloroplasts contain chlorophyll, allowing the organism to perform photosynthesis and produce its own food.

Do parameciums have chloroplast?

No, parameciums do not have chloroplasts. They are single-celled organisms belonging to the group of protists, and they are not capable of photosynthesis. Instead, parameciums obtain their energy by feeding on bacteria and other small organisms.

Why does a pure chlorophyll flouresces when exposed to light?

Chlorophyll molecules become excited when photons of light strike them. This excitement results in valence electrons moving to a higher energy level. The electrons are transferred through many pigments called antenna pigments until they reach a pigment called the Reaction Center. Normally, the Reaction Center would pass these electrons on to an electron transport chain, but, since pure chlorophyll does not have any electron transport chains, the electrons, which are highly unstable, simply return to their original energy level. Energy is released as the return, and this energy is what we see as fluorescent light.

Can a plants chlorophyll be altered or damaged?

Yes, a plant's chlorophyll can be altered or damaged by factors such as high temperatures, excessive sunlight exposure, nutrient deficiencies, diseases, and pollution. These factors can affect the plant's ability to photosynthesize efficiently, resulting in decreased growth and potential damage to the plant.

Is chlorophyll present in Gloeocapsa?

Yes, chlorophyll is present in Gloeocapsa. Gloeocapsa is a type of cyanobacteria, also known as blue-green algae, that contains chlorophyll for photosynthesis.

Do archabacteria have chloroplasts?

No, archaea do not have chloroplasts. Chloroplasts are primarily found in plants and algae, which belong to a different domain of life called Eukarya. Archaea are a separate domain of prokaryotic organisms that do not possess organelles like chloroplasts.
