How does affect sunlight growth of plants conclusion?

when the sunlight reaches the plant the plant responses to the light in effect of growth and food. in this case the question is about food the plant knows what to do because it is a stimuli. all it is that the plant wants to be the one to reach the light and have so no other one can but every one knows that is impossible.

Which of these is NOT a structure or chemical found in a chloroplast?

Mitochondria. Mitochondria are organelles involved in cellular respiration, while chloroplasts are organelles involved in photosynthesis.

What process does the chloroplast do?

It contains chloroplasm. They are normally situated in the top layers of the leaves to absorb as much sunlight energy

The reason plants need this is this:

Sunlight Energy

CO2 + H2O --> C6 H12 O6 + O2 Or

in other words

Sunlight Energy

Carbon dioxide +Water -->Glucose + Oxygen

The Proper formula has the sunlight energy above the arrow - and it has to be an arrow not an = sign

The chloroplast carries out photosynthesis, the conversion of Carbon dioxide +Water -->Glucose + Oxygen (plus Sunlight Energy) to keep it alive

Why mitochondria and chloroplast are called semi autonomous organelles?

Semi-autonomous because mitochondrial replication is controlled by the cell.

Mitochondria retain only a portion of their genome. Another, larger, portion of its genome has been moved to the cell nucleus. Thus the reproduction is under the nucleus' control. This coordinates mitochondrial reproduction by responding to cell division and cellular physiological stresses, but not by the mitochondria's control. However the exact pathway for mitochondrial biogenesis is yet to be worked out.

The gene transfer theory of endosymbiosis:

Gene transfer from the mitochondrion into the nucleus

Do chloroplast synthesize ATP?

Chloroplasts do not directly synthesize ATP. They produce ATP through the process of photosynthesis, where light energy is converted into chemical energy and stored in the form of ATP molecules. This ATP can then be used by the plant cell for cellular processes.

Is water a fluid in the chloroplast?

Yes, water is a fluid inside the chloroplast. It plays a critical role in photosynthesis by providing the medium for chemical reactions to occur. Water is involved in the light-dependent reactions, where it is split to release oxygen and electrons that drive the production of ATP and NADPH.

Do animal cells have have chloroplast?

No,they do not have.Only plants and algae have.

What is the compound in a chloroplast that traps energy and gives the chloroplast its green color?

The compound in a chloroplast that traps energy and gives the chloroplast its green color is chlorophyll. Chlorophyll is a pigment that absorbs sunlight during photosynthesis, allowing plants to convert light energy into chemical energy.

What job does a chloroplast cell in a plant do?

Chloroplasts are responsible for photosynthesis in plant cells. During photosynthesis, chloroplasts convert sunlight, carbon dioxide, and water into glucose (sugar) and oxygen, which is essential for the plant's energy and growth.

In what way do chloroplasts indicate the existence of a cell cytoskeleton?

Chloroplasts are anchored in the cell by the cell cytoskeleton, which helps support their positioning within the cell. The cytoskeleton provides a structural framework that allows organelles like chloroplasts to move and maintain their position within the cell.

What is cooperation of the two photosystems of the chloroplast is required for?

The cooperation of the two photosystems (Photosystem I and Photosystem II) is required for the efficient production of ATP and NADPH during the light-dependent reactions of photosynthesis. Photosystem II generates ATP through the electron transport chain, while Photosystem I produces NADPH. Working together, they create the energy carriers needed to fuel the Calvin cycle, where carbon fixation occurs.

What processes could still occur in a chloroplast in the presence of an inhibitor that prevents H from passing through ATP synthase complexes?

In the presence of an inhibitor that prevents H from passing through ATP synthase complexes, photosynthesis processes that generate ATP would be impaired. However, other processes in the chloroplast, such as the light-dependent reactions that produce oxygen and NADPH, could still proceed as they are not directly reliant on ATP generated by ATP synthase complexes for their functioning. The overall efficiency of photosynthesis would be reduced due to the lack of ATP production.

Is chlorophyll and glucose the same thing?

No, chlorophyll and glucose are not the same thing. Chlorophyll is a pigment found in plants that is essential for photosynthesis, while glucose is a simple sugar produced during photosynthesis that serves as a source of energy for the plant.

Which part of a mango tree would contain cells with the greatest number of chloroplasts?

The leaves of a mango tree would contain cells with the greatest number of chloroplasts. This is because chloroplasts are responsible for photosynthesis, and leaves are the main site of photosynthesis in plants.

What is an important plant sugar made in the chloroplasts?

Glucose is an important plant sugar produced during photosynthesis in the chloroplasts. It is a key source of energy for plant cells and is essential for their growth and metabolism.

What step during Krebs cycle do electrons pass down the electron transport chain?

During the Krebs cycle, the electrons are carried by NADH and FADH2 to the electron transport chain, where they pass down a series of protein complexes to generate ATP through oxidative phosphorylation. This occurs after the formation of NADH and FADH2 during the Krebs cycle.

What plants uses energy from sunlight to make sugar?

Plants use a process called photosynthesis to capture energy from sunlight and convert it into sugar (glucose) for energy. This process involves utilizing chlorophyll in their cells to absorb sunlight and convert carbon dioxide and water into glucose and oxygen.

How do scientists think chloroplasts evolved?

Scientists believe that chloroplasts evolved from ancient photosynthetic bacteria that were engulfed by ancient plant cells through a process called endosymbiosis. Over time, these bacteria formed a symbiotic relationship with the host cell, eventually becoming what we now recognize as chloroplasts. This theory is supported by the structural and genetic similarities between chloroplasts and modern photosynthetic bacteria.

Why are Chlorophytes considered close relatives of land plants?

Chlorophytes are considered close relatives of land plants because they both belong to the group of green algae, and share many genetic and structural characteristics. Both chlorophytes and land plants contain chlorophyll a and b pigments, have cellulose cell walls, and undergo similar reproductive processes. This shared evolutionary history suggests a common ancestor and close relationship between the two groups.

What would happen if the molecule RuBP no longer functioned in a plant?

If the molecule RuBP (Ribulose-1,5-bisphosphate) no longer functioned in a plant, the Calvin Cycle, which is a key part of photosynthesis, would be disrupted. This would negatively impact the plant's ability to fix carbon dioxide and produce energy, ultimately leading to a decrease in plant growth and productivity.

Why do cells need Mitochondria smooth ER lysosomes and chloroplasts?

Mitochondira = the power houses of the cell

Smooth Er = Endoplasmic Reticulum, which is a passageway that materials are transported through.

Lysosomes = Break down old cells and excess food.

Chloroplasts = Found only in plant cells and are used in photosynthesis.

Hope this Helps! :)

Are chloroplasts present in elodea oblong cells?

Yes, chloroplasts are present in Elodea oblonga cells. Elodea is a type of aquatic plant that contains chloroplasts in its cells to facilitate photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts are responsible for producing energy-rich molecules that help the plant grow and survive.

What helps electron-carrying molecules move along the membranes of mitochondria and chloroplasts?

In mitochondria, electron-carrying molecules are moved along the membranes by protein complexes that pump protons across the inner membrane, creating an electrochemical gradient. In chloroplasts, electron-carrying molecules are helped along by the thylakoid membrane's structure, which provides a platform for electron transport proteins to interact and facilitate the movement of electrons during photosynthesis.
