Chloroplasts

Chloroplasts are organelles found in plant cells that are responsible for conducting photosynthesis, where light energy is converted into chemical energy for the plant to use as food. These organelles contain chlorophyll, a pigment that gives plants their green color and allows them to absorb light energy.

Chloroplasts do not "eat" in the same way that animals do. They contain chlorophyll and other pigments that capture sunlight and convert it into chemical energy through photosynthesis. This helps plants produce their own food by converting carbon dioxide and water into sugars.

The parts involved in chloroplast trapping of light are the thylakoid membrane, where photosystems I and II are located, and the pigments such as chlorophyll within these photosystems. Light energy is absorbed by these pigments and transferred to specialized chlorophyll molecules in the reaction center, initiating the process of photosynthesis.

The generally accepted concept is endosymbiotic theory, which suggests that mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells. Over time, these prokaryotic organisms formed a symbiotic relationship with the host cell, leading to their integration as organelles within eukaryotic cells. This process allowed for the specialization and evolution of these organelles to carry out specific functions within the cell.

One way to remember what chloroplasts do is to think of them as the "food factories" of plant cells. They are responsible for photosynthesis, converting sunlight into energy-rich sugars that plants use as food. So, you can think of chloroplasts as the powerhouses that provide plants with the energy needed to grow and survive.

Compound microscopes can see the nuclei of cells. More powerful instruments such as an electron microscope can reveal the smallest components of organelles, and even the molecular structure of the cell's components.

To study the membranes of a chloroplast, you could use techniques such as electron microscopy to visualize the membranes at a high resolution, biochemical fractionation to isolate and analyze the different membrane components, and functional assays to study the activities of specific membrane proteins.

If chloroplasts in a plant got destroyed the plant will eventually die because the chloroplasts are what makes the chlorophyll in a plant which is needed for photosynthesis and without the plants oxygen we will die.

Chloroplasts are where photosynthesis occurs in plant cells. They contain chlorophyll, a pigment that absorbs light energy for photosynthesis. Within the chloroplasts, light energy is used to convert carbon dioxide and water into glucose and oxygen, providing energy and food for the plant.

When the energy from the sun is trapped by chlorophyll, it excites electrons within the chlorophyll molecules. These excited electrons are then used to fuel the process of photosynthesis, where carbon dioxide and water are converted into glucose and oxygen.

Thylakoids, stroma, and grana are specialized structures found in chloroplasts. Thylakoids are membrane-bound compartments where photosynthesis occurs, while grana are stacks of thylakoids. Stroma is the fluid-filled space where the Calvin cycle takes place.

Auxin is involved in cell growth and elongation, while gibberellins are involved in stem elongation, seed germination, and flowering. Ethylene regulates fruit ripening, leaf abscission, and senescence in plants. Each of these plant hormones has distinct functions in growth and development.

In chloroplasts, the process of photosynthesis occurs, where light energy is converted into chemical energy by capturing sunlight and using it to produce glucose (sugar) from carbon dioxide and water. This process involves two main stages: the light-dependent reactions, which occur in the thylakoid membranes and generate ATP and NADPH, and the light-independent reactions (Calvin cycle), which take place in the stroma and use ATP and NADPH to produce glucose.

The presence of their own circular DNA and the ability to divide on their own are two characteristics of chloroplasts that enable them to self-replicate.

You can use alternative light sources such as grow lights or LEDs to provide the necessary light for photosynthesis in a cage that is meant to support plants. These alternatives can mimic natural sunlight and help plants thrive without the need for chloroplasts.

A loss of chlorophyll in plant cells would reduce the amount of glucose produced through photosynthesis, which is a crucial energy source for cellular respiration. This would result in a decrease in the amount of substrate available for cellular respiration to produce ATP, impacting the overall energy production of the cell.

Phytoplankton are the group of plankton that contain chloroplast in their cells. These photosynthetic organisms use chloroplasts to convert sunlight into energy through the process of photosynthesis.

Mammals are animals, and therefore their cells do not contain chloroplasts.

However, they do rely on chloroplasts to create their food. Chloroplasts are responsible for photosynthesis - when sunlight is used to create glucose from non-organic molecules. This is vital for all life. The plants that animals eat all rely on photosynthesis to survive.

No, mitochondria do not have thylakoids. Thylakoids are a membrane system containing chlorophyll found in chloroplasts, while mitochondria have inner and outer membranes but do not contain thylakoids. Mitochondria are involved in cellular respiration, not photosynthesis like chloroplasts.

Grana Padano can be enjoyed on its own as a table cheese, grated over pasta or risotto, added to salads, or served with fruits and nuts. It's also delicious paired with a variety of wines and makes a great addition to a cheese platter.

Yes, Gloeocapsa is a photosynthetic organism and contains chloroplasts which enable it to carry out photosynthesis to produce energy from sunlight.

No, chloroplasts are not found in the human body. Chloroplasts are specialized organelles found in plant cells and other autotrophic organisms that are responsible for photosynthesis, converting sunlight into energy. Humans do not have the ability to photosynthesize and therefore do not possess chloroplasts.

Fungi have cell walls containing chitin but do not have chloroplasts for photosynthesis. Instead of producing their own food through photosynthesis, fungi are heterotrophic, obtaining nutrients by absorbing organic matter from their environment.

The process whereby mitochondria and chloroplasts in protists arise is through endosymbiosis, where an ancestral eukaryotic cell engulfed a prokaryotic cell (which evolved into a mitochondria or chloroplast) forming a symbiotic relationship. Over time, these organelles integrated into the host cell and developed a mutually beneficial relationship, providing energy and photosynthetic capabilities to the host cell.
