Chloroplasts

Chloroplasts are a part of a plant's cell. They capture energy from light.

Do all living things have chloroplasts?

No, in fact no animals create chloroplasts. Some animals can, however, engulf other photosynthetic organisms and through either a symbiotic relationship with the photosynthetic organism or by appropriation of photosynthetic mechanisms these animals can photosynthesize. An example of this would be the sea slug Elysia chlorotica which eats algae. It has a unique digestive tract that does not digest the algal chloroplasts for energy but instead engulfs them into the slugs tissues via phagocytosis. The chloroplasts can "survive" for several months before new chloroplasts are needed to replace the old ones. This is because the slug itself does not create the chloroplasts but steals them from the algae and incorporates them into its own tissues.

How many chloroplast per cell does moss have?

Moss cells typically have multiple chloroplasts per cell, ranging from 10 to 100 chloroplasts per cell. This is because moss relies on photosynthesis for energy production, and having more chloroplasts increases the surface area for capturing sunlight.

The chlorophyll of the green algae is in chloroplasts True or False The chlorophyll of the green algae is in chloroplasts. True or False?

True. Chlorophyll in green algae is located within specialized structures called chloroplasts. These chloroplasts are responsible for carrying out photosynthesis in green algae, where chlorophyll captures light energy and converts it into chemical energy for the organism.

Mitochondria and chloroplasts are the other organelles besides the nucleus that contain?

Mitochondria and chloroplasts contain their own DNA and ribosomes, allowing them to carry out some cellular functions independently of the rest of the cell. This is because they are believed to have originated from ancient prokaryotic organisms that were engulfed by eukaryotic cells in a process known as endosymbiosis.

In what kinds of cells are chloroplast found?

Chloroplasts are found in green photosynthetic cells of plant tissues

Why do plant cells have chloroplasts but animal cells do not?

Chloroplasts contain chlorophyll. Chlorophyll is the chemical needed for photosynthesis - using energy from the sun with carbon dioxide to make sugar. Plants need this because it is their only energy source (with some exceptions such as venus fly traps)

Animals eat plants or other animals, and so do not need to conduct photosynthesis as they have another energy source. If there is no need to photosynthesise there is no point in making chloroplasts.

Why are chloroplasts found in Elodea cells and not in the cells of a root tip?

Chloroplasts are found in Elodea cells because Elodea is an aquatic plant that performs photosynthesis to produce energy from sunlight. Root tips primarily function in nutrient uptake and protection for the plant, so they do not contain chloroplasts since these activities do not require photosynthesis.

The cell stores fats and starchs where A vacuoles B the nucleus C chloroplasts D ribosomes E mitocondria?

A vacuoles stores fats and starches in plant cells, while mitochondria produce energy, ribosomes carry out protein synthesis, the nucleus contains genetic material, and chloroplasts are responsible for photosynthesis.

Look like stacks of coins and are found in the chloroplasts?

Thylakoids are membrane-bound structures that contain chlorophyll and other pigments in chloroplasts. They resemble stacks of coins and are where the light-dependent reactions of photosynthesis occur, converting light energy into chemical energy. This energy is then used to produce ATP and NADPH for the Calvin cycle in the stroma of the chloroplast.

Where would the greatest number of chloroplast be found in a leaf?

The greatest number of chloroplasts can be found in the palisade mesophyll cells, which are located in the upper layer of the leaf where they receive the most light for photosynthesis. This is the primary site for photosynthesis in most plants.

How many membranes enclose the contents of the chloroplast?

Two membranes enclose the contents of the chloroplast - the outer membrane and the inner membrane.

What is a membrane system found within chloroplasts that contain the components for photosynthesis?

The membrane system found within chloroplasts that contains the components for photosynthesis is called the thylakoid membrane. It is where light reactions of photosynthesis take place, including the capture and conversion of light energy into chemical energy. The thylakoid membrane also houses the photosystems, electron transport chain, and ATP synthase that are essential for the process of photosynthesis.

Where else in chloroplasts does chemiosmosis translocates protons from?

Protons are translocated from the stroma to the thylakoid lumen in chloroplasts during chemiosmosis. This creates a proton gradient that is used by ATP synthase to generate ATP through the process of photophosphorylation.

Do nerve cells contain chloroplasts?

No, nerve cells do not contain chloroplasts. Chloroplasts are found in plant cells and are responsible for photosynthesis, which is the process by which plants convert sunlight into energy. Nerve cells do not have this function as they are specialized for transmitting electrical signals in the nervous system.

What would happen to a plant if its chloroplasts stopped working?

Chloroplasts are doing photosynthesis. They will die if chloroplasts are not working.

Plant chloroplasts convert the energy of sunlight into what?

Plant chloroplasts convert the energy of sunlight into chemical energy in the form of glucose through a process called photosynthesis. This chemical energy is used by the plant for growth, reproduction, and metabolism.

What is the region outside the chloroplast?

The region outside the chloroplast is called the cytoplasm. It is a gel-like substance that fills the cell and contains various organelles, including the mitochondria, endoplasmic reticulum, and ribosomes. The cytoplasm plays a key role in supporting various cellular processes, such as protein synthesis and energy production.

How do chloroplasts and mitochondria work together in a plant cell?

Chloroplasts are responsible for photosynthesis, converting sunlight into chemical energy. Mitochondria then use this energy to generate ATP through cellular respiration. Together, they maintain the energy balance within the cell, with chloroplasts producing energy and mitochondria utilizing it efficiently.

Do fungus have chloroplasts?

No, fungi do not have chloroplasts. Chloroplasts are found in plants and algae, where they are responsible for photosynthesis. Fungi obtain their nutrients from other sources and do not perform photosynthesis.

What is chloroplast do?

Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into energy by using carbon dioxide and water to produce glucose and oxygen. This process is essential for the plant's survival and provides oxygen for other living organisms.

Do Prokaryotes have chloroplasts?

No they don't.They are only in eukariyotes. Prokariyotes have photosynthetic filaments

What is unique about chloroplast and mitochondria?

Chloroplasts are unique because they contain chlorophyll and are responsible for photosynthesis in plant cells. Mitochondria are unique because they generate energy in the form of ATP through cellular respiration. Both organelles have their own DNA and can replicate independently within the cell.

Do chloroplasts have ribosomes?

Yes, chloroplasts (plastid) in plants, algae and some protists and mitochondria of all Eukaryotes containing their own DNA that produce RNA and make proteins. They thought to be originated as a result of endosymbiosis!

What are the three general groups of plant pigments?

The three types of pigments found in a plant are chlorophyll a, chlorophyll b, and carotenoids (mainly carotene). Chlorophyll a (the main pigment) absorbs blue-green light, chlorophyll b absorbs yellow-green light, and carotene absorbs yellow-orange light.
