Chloroplasts

Yes, avocado cells contain chloroplasts which are responsible for photosynthesis, the process by which plants convert sunlight into energy.

The materials that enter the chloroplast for use in the light-dependent reactions include water molecules and light energy. Water is split into oxygen, protons, and electrons, while light energy is absorbed by chlorophyll to initiate the photosynthetic process.

The outer membrane of the chloroplast is called the chloroplast envelope. It consists of the outer and inner membrane, which together enclose the stroma, where important processes like photosynthesis occur.

The second stage of photosynthesis, which takes place in the stroma of the chloroplast, can occur without the presence of sunlight. In this stage, known as the Calvin Cycle, carbon molecules from CO2 are fixed into glucose (C6H12O2). The reactions of the Calvin Cycle is as follows:

1. A five-carbon sugar molecule called ribulose bisphosphate, or RuBP, is the acceptor that binds CO2 dissolved in the stroma. This process, called CO2 fixation, is catalyzed by the enzyme RuBP carboxylase, forming an unstable six-carbon molecule. This molecule quickly breaks down to give two molecules of the three-carbon 3-phosphoglycerate (3PG), also called phosphoglyceric acid (PGA).

2. The two 3PG molecules are converted into glyceraldehyde 3-phosphate (G3P, a.k.a. phosphoglyceraldehyde, PGAL) molecules, a three-carbon sugar phosphate, by adding a high-energy phosphate group from ATP, then breaking the phosphate bond and adding hydrogen from NADPH + H+.

Three turns of the cycle, using three molecules of CO2, produces six molecules of G3P. However, only one of the six molecules exits the cycle as an output, while the remaining five enter a complex process that regenerates more RuBP to continue the cycle. Two molecules of G3P, produced by a total of six turns of the cycle, combine to form one molecule of glucose.

Doode. Like people need to start answering these question because like I dont know the answers at all.

Chloroplast works by capturing energy from the sun to make food for a plant. Chloroplast is not in animals. Chloroplast is green. I hope that answers ur?

Chloroplasts convert sunlight into chemical energy. Animal cells do not need these because they gain their food from other sources besides sunlight.

The internal membrane system of the chloroplast is called the thylakoid membrane. It is where the light-dependent reactions of photosynthesis occur, including the conversion of light energy into chemical energy.

No, grana are not the site of ATP production within a chloroplast. ATP is primarily produced in the stroma of the chloroplast through the process of photosynthesis. Grana, on the other hand, contain chlorophyll pigments and are responsible for capturing light energy used in the conversion of light energy into chemical energy.

The leaves are the only cells which contain chloroplasts, as an objective of the leaf is to absorb sunlight, which is exactly what the chloroplasts, or more specifically the chlorophyll in the chloroplasts do. The chloroplasts themselves are the organelles in which photosynthesis takes place.

Chlorophyll is the substance found in chlorolast which is responsible for photosynthesis. The sites in the chloroplast where chlorophyll is found in the inner and outer membrane. A third site is in the membrance of the thylakoid where chlorophyll and carotenoids are found in the granum (stack of thylakoids).

Plant cells have both chloroplasts and mitochondria. Chloroplasts are responsible for photosynthesis, converting light energy into sugar, while mitochondria produce energy for the cell through cellular respiration.

No, the kingdom protista also has some cell types containing chloroplasts, as it is the kingdom where unknown cell types are thrown. The main kingdom where chloroplasts are located is in the plant kingdom (plantae).

Both chloroplasts and mitochondria are organelles found in eukaryotic cells that are involved in energy production processes - chloroplasts are involved in photosynthesis to produce energy from sunlight, while mitochondria are involved in cellular respiration to produce energy from glucose. Both organelles also have their own DNA and ribosomes, suggesting they may have evolutionary origins from symbiotic bacteria.

It allows seeds to detect their orientation. That way, the stem system can grow towards the surface while the root system extends further into the earth. Plants need this adaptation to avoid extending the stem in the wrong direction. If the stem where to grow down instead of up, or the roots where to grow up instead of down, the plant would be unable to pull the nutrients from the deeper soil, and the stem would be unable to perform photosynthesis. Both actions are needed for the plant to get enough food to survive.

Chloroplasts are typically green in color due to the presence of chlorophyll pigments. Chlorophyll absorbs blue and red light while reflecting green light, giving chloroplasts their characteristic green color.

Plants, algae, and some species of protists contain chloroplasts. These organelles are responsible for conducting photosynthesis, the process by which sunlight is converted into energy for the organism.

No, chlorophyll is located in the thylakoid membranes within the chloroplasts, not in the stroma. The stroma is the fluid-filled space surrounding the thylakoid membranes where the Calvin cycle takes place.

Chloroplasts make food in the form of glucose through a process called photosynthesis. This process involves capturing sunlight energy and converting it into chemical energy stored in glucose molecules.

The Krebs cycle takes place in the mitochondrial matrix of a cell, not in the chloroplast.

Chloroplasts are most abundant in the cells of green plants, specifically in the leaf cells. These cells are known as mesophyll cells and are responsible for photosynthesis, where chloroplasts capture sunlight to produce energy for the plant.

No, protests do not have chloroplasts. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. Protest is a form of expressing opposition or disagreement.

Chloroplast DNA (cpDNA) resembles bacterial DNA in terms of size, structure, and gene content. This is because chloroplasts are believed to have originated from an ancient endosymbiotic event where a photosynthetic bacterium was engulfed by a eukaryotic cell.

Chloroplasts play a crucial role in photosynthesis, converting sunlight into energy-rich molecules like glucose, which can be utilized by the cell for growth and metabolism. They also help in producing oxygen as a byproduct of photosynthesis, essential for cellular respiration. Additionally, chloroplasts are involved in the synthesis of certain amino acids, lipids, and pigments that contribute to the overall health and function of the cell.

When a chloroplast dies, it breaks down and releases its components back into the cell. These components can be recycled by the cell or broken down further for energy. In some cases, the cell may also remove the remnants of the chloroplast through a process called autophagy.

A chloroplast is a specialized organelle found in plant cells that is responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts contain chlorophyll, the pigment that gives plants their green color and allows them to absorb light for photosynthesis.

Mitochondria act like chloroplasts in plants as they both generate energy for the cell through cellular respiration and photosynthesis, respectively. Both organelles have their own DNA and ribosomes, supporting the endosymbiotic theory that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by a primitive eukaryotic cell.
