Chloroplasts are organelles found within plant and algal cells. They are membrane-bound and contain chlorophyll, which is used in photosynthesis to convert energy from light into chemical energy stored in sugars.
Chloroplasts are unique in that they are considered to be eukaryotic organelles as they contain a membrane-bound nucleus, as well as other membrane-bound organelles. This is a unique feature of eukaryotes, and is distinct from prokaryotes, which lack a membrane-bound nucleus.
Inside chloroplasts is a high concentration of thylakoids, which are an array of vesicles that serve as the site of photosynthesis. Inside each thylakoid is where the pigments and enzymes needed for photosynthesis are located.
Thus, chloroplasts are eukaryotic organelles that are used for photosynthesis in plants and algae.

Are chloroplasts in eukaryotes?
Yes, chloroplasts are found in eukaryotes. Chloroplasts are only found in eukaryotic cells, and they are thought to have evolved 1. 5 billion years ago when mitochondria joined together and formed a symbiotic relationship with the host cell.
Chloroplasts are responsible for photosynthesis, the process of using light energy to convert carbon dioxide and water into carbohydrates and oxygen. This process is essential to life on Earth, as it is the primary source of food for virtually all living organisms in the form of carbohydrates.
Chloroplasts have a double membrane composed of a thin inner envelope and a thick outer membrane. Within the chloroplast is a colloidal matrix called the stroma that contains multiple flattened sacs called thylakoids.
These thylakoids are interconnected and packed into stacks called grana. Chloroplasts also contain DNA and ribosomes, just like other parts of the eukaryotic cell.
What is chloroplast classified as?
Chloroplasts are classified as organelles, which are self-contained structures within a living cell that have a specific function. Chloroplasts exist primarily in plant and algae cells and serve a variety of functions, including the production of food.
Specifically, the process of photosynthesis takes place inside the chloroplasts, in which energy from the sun is used to convert carbon dioxide and water into glucose, which is then used for energy by the plant.
Chloroplasts also play a role in plant immunity and hormone synthesis.
Is chloroplast a plant animal or bacteria?
Chloroplasts are organelles which are found in eukaryotic cells, primarily in plants, algae, and some other species. Chloroplasts are not plants, animals, or bacteria. They are their own unique organelle, distinct from these three life forms.
Chloroplasts contain chlorophyll, a green pigment that absorbs light energy and is used in photosynthesis. Photosynthesis is the process of using the energy from the sun, water, and carbon dioxide to generate energy-rich sugars and oxygen.
Chloroplasts also contain several enzymes needed for glycolysis, the most important stage of cellular respiration. Overall, chloroplasts are essential organelles necessary for plant, algae, and some other species to survive.
Which species have chloroplasts?
Chloroplasts are organelles found exclusively in plants and some other organisms. They are responsible for photosynthesis which involves the conversion of light energy into chemical energy. The organisms with chloroplasts include eukaryotes such as algae and other photosynthetic protists, and species of higher plants such as angiosperms, gymnosperms, and some vascular plants like ferns and mosses.
Different chloroplasts vary according to the plant’s species and the environment in which it lives.
Most chloroplasts are 1 to 10 micrometers in diameter. They contain many folded internal membranes that are filled with chlorophyll, and also contain other pigment molecules. These pigments absorb energy from sunlight and convert it into chemical energy.
This process of photosynthesis powers the organism, allowing it to grow and reproduce. Photosynthesis can also help to create new organic compounds from carbon dioxide in the environment and helps to maintain the oxygen level and balance of carbon dioxide in the atmosphere.
The pigment molecules and chlorophyll molecules within the chloroplast absorb and reflect different wavelengths of light, which brings out the green color in plants. This is the reason why plants are mostly green in color.
In conclusion, the organisms that have chloroplasts are species of higher plants such as angiosperms, gymnosperms, and some vascular plants such as ferns and mosses, as well as eukaryotes like algae and other photosynthetic protists.
Chloroplasts are important for photosynthesis, and also give plants their characteristic green color.
Is chloroplast an organ or organelle?
Chloroplasts are organelles, not organs. Organelles are sub-structural parts of a cell, while organs are composed of groups of tissues that all work together to provide a specific function, such as respiration or digestion.
Chloroplasts are found in all plant and algal cells, and are the sites of photosynthesis – the process by which plants and algae use the energy from the sun to convert carbon dioxide and water into glucose and oxygen.
Chloroplasts are specialized compartments encased in a double membrane that contain a gel-like material called stroma. This contains a number of different cellular components such as thylakoids, pigments, enzymes, and proteins, which all serve different functions in photosynthesis.
Is chloroplast a Heterotroph or Autotroph?
Chloroplasts are essential organelles found in photosynthetic organisms, including plants, algae, and some species of bacteria. The purpose of the chloroplast is to facilitate the process of photosynthesis, where light energy is harvested and converted into carbohydrate molecules.
In this way, these organisms are able to use light energy as a source of energy to power their metabolic processes, such as respiration and other normal cellular functions. As such, photosynthetic organisms like plants, algae, and some bacteria are considered to be autotrophs, or self-feeding organisms, meaning they produce their own food.
That food is produced in the form of sugar molecules, which are created through photosynthesis. Without the light energy to fuel their photosynthetic processes, autotrophs like plants, algae, and bacteria would not be able to survive and so would be considered heterotrophs, or organisms that rely on other sources for food.
Can eukaryotes do photosynthesis?
Yes, some eukaryotes can do photosynthesis. Autotrophic eukaryotes use light or other energy sources to synthesis their own food, a process known as photosynthesis. You may not recognize the term, but you know some of these eukaryotes—algae, certain protists, and some fungi all use photosynthesis to create energy and build their bodies.
The process of photosynthesis occurs in the chloroplasts of eukaryotes, which are the parts of the cell responsible for capturing sunlight and creating chemical energy. During photosynthesis, eukaryotes take in sunlight, carbon dioxide, and water, and then convert them into energy, oxygen and glucose.
Glucose is a type of sugar molecule and is used by eukaryotes as a source of energy. Oxygen is then returned to the atmosphere, where it is used by anaerobic organisms and humans going about their daily activities.
By using the chloroplasts in their cells, eukaryotes are able to convert the light energy from the sun into chemical energy that is stored in the cells for later use. This energy source is used for all sorts of activities, from growth and development to movement, reproduction, and even the digestion of food.
Eukaryotes are able to capture energy from the sun and this energy is used to power all of the activities that make up their lives.
The ability to do photosynthesis is not limited to just all eukaryotes, however. Some eukaryotes rely on extracellular sources for energy, such as eating other organisms or accessing other energy sources.
Photosynthesis enables eukaryotes to use the sun as an energy source and build their bodies without relying on other organisms or energy sources.
How is prokaryotic different from eukaryotic cell?
Prokaryotic cells and eukaryotic cells are two different types of cells with distinct characteristics and structures. Prokaryotic cells are smaller than eukaryotic cells, generally ranging from 0. 2 to 2.
0 micrometers in diameter. They do not have a nucleus, and the genetic material is not surrounded by a nuclear membrane. Instead, the genetic material is found in the form of a single circular chromosome within the cytoplasm of the cell.
Also, unlike eukaryotic cells, prokaryoses lack membrane-bound organelles and have simpler cell structures with fewer internal components.
In contrast, eukaryotic cells are much larger in size, usually ranging from 10 to 100 micrometers in diameter. They possess a true nucleus, which is a membrane-bound structure that contains the cell’s genetic material.
This genetic material is found in the form of multiple linear chromosomes. And, eukaryotes have several membrane-bound organelles such as the endoplasmic reticulum, mitochondria, and Golgi bodies, each of which have specialized functions within the cell.
In summary, prokaryotic cells are smaller, don’t have a nucleus, and have fewer internal components than eukaryotic cells. Conversely, eukaryotic cells are much larger and contain a nucleus with multiple linear chromosomes, as well as several membrane-bound organelles.
