What are two organisms that have chloroplasts?
Plants and algae are two organisms that have chloroplasts. Chloroplasts are responsible for photosynthesis, the process by which plants and some microorganisms convert sunlight into energy.
Why do plants need chloroplasts?
Chlorine: is involved in the regulation of movement of water and other solutes into and out of cells. Chlorine is essential for cell division in leaves and in the regulation of opening and closing stomata. It is also involved in photosynthetic transfer of oxygen and nitrogen metabolism. Symptoms of issues can include yellowing of the veins in older leaves, wilting of the leaves and stunted root growth. Too much chlorine is very detrimental to plants, as with build up it can become a deadly toxin to the plant not to mention it's ability before those levels to effect nutrient uptake.
What is the process that takes place in a chloroplast?
In a chloroplast, the process of photosynthesis occurs. This process involves capturing sunlight energy and converting it into chemical energy in the form of glucose. This energy conversion involves the use of chlorophyll and various enzymes within the chloroplast.
What is the description of a chloroplast?
Chloroplasts occur in a variety of shapes and sizes, such as corkscrewlike ribbons or bracelet-shapes found in certain green algae. The chloroplasts of higher plants, however, tend to be shaped somewhat like two frisbees glued together along their edges, and when they are sliced in median section they resemble the outline of a football. Chloroplasts may be from 2 to 10 micrometers in diameter, and each is bounded by an envelope consisting of two delicate unit membranes . The outer membrane apparently is derived from endoplasmic reticulum whereas the inner membrane is believed to have orginated from the cell membrane of a blue-green bacterium. Within is a colorless, fluid, enzyme-containing matrix, called the stroma. Grana (singular: granum), which are stacks of coin-shaped double membranes called thylakoids are suspended in the stroma. The membranes of the thylakoids contain green chlorophyll and other pigments. Theses "coin-stacks" of grana, are vital to life as we know it on our planet today, for it is within the thylakoids that the first steps of the all-important process of photosynthesis occurs.
Do plant Cells have chloroplasts?
Yes, plant cells have chloroplasts, which are specialized organelles that contain chlorophyll and are responsible for photosynthesis. Photosynthesis is the process by which plants convert sunlight into energy to produce their own food.
Which cells would you expect to have the most chloroplast?
Cells in plant leaves would be expected to have the most chloroplasts because they are specialized for photosynthesis. Specifically, the palisade mesophyll cells located in the upper layer of the leaf would have the highest concentration of chloroplasts due to their role in capturing sunlight for photosynthesis.
What evidence indicates that mitochondria and chloroplasts were once free-living organisms?
Both have their own DNA, and manufacture their own RNA and proteins. When the DNA was examined, it was resembled the DNA in free-living organsims known as blue-green algae, so it was hypothesized that these organelles were once free-living and then became endosymbionts with another organism.
Do all plant cells have chloroplasts?
No, for example, onion plant cells don't. Even in green plants, chloroplasts are not in each cell, only in ones that receive sunlight.
The presence of chloroplasts (green color) in the cells of a plant are an indicator of whether or not those cells are photosynthetic. Almost all terestrial plants are photosynthetic, but that does not mean that all of a single plant's cells are photosynthetic as described above. Photosynthetic cells are specialized to make sugar for the plant's energy needs from atmospheric carbon dioxide. The cells in other parts of the plant have other specialized functions.
Chlorophyll is contained in chloroplasts, which are specialized organelles found in plant cells. This green pigment is essential for photosynthesis, the process by which plants convert sunlight into energy.
What model is used to explain the origin of mitochondria and chloroplasts within eukaryotic cells?
I believe you are referring to the Endosymbiotic theoryby Lynn Margulis. She came up with the theory that states that eukaryotic cells engulfed smaller bacteria and over time, they became specialized organelles within eukaryotic cells.
What function do the chloroplasts serve?
Chloroplasts are responsible for photosynthesis, where they capture sunlight and convert it into chemical energy stored in the form of glucose. This process sustains plant life by producing oxygen as a byproduct and providing energy for growth and metabolism.
What does the chloroplast do for the cell?
Chloroplasts are organelles in plant cells responsible for photosynthesis, the process of converting light energy into chemical energy in the form of glucose. Chloroplasts contain chlorophyll, a pigment that captures sunlight and converts it into chemical energy for the plant to use as food.
What is the name of the most important chloroplast pigment?
The most important chloroplast pigment is chlorophyll. It is responsible for capturing light energy during photosynthesis and is essential for the plant's ability to convert light energy into chemical energy.
The reaction is likely an endothermic reaction. In an endothermic reaction, heat is absorbed from the surroundings, causing a decrease in temperature.
This stack of thylakoids catches the light?
Yes, thylakoids are membrane-bound structures in chloroplasts where the light-dependent reactions of photosynthesis occur. They contain chlorophyll pigments that absorb light energy, which is then used to drive the synthesis of ATP and NADPH. The arrangement of thylakoids in stacks called grana helps to maximize light absorption and efficiency in photosynthesis.
The primary light-gathering pigment in photosynthetic bacteria and plants is what?
Chlorophyll is the primary pigment in plants. It gives the green color to plants. Its main function is to help in the synthesis of carbohydrates from carbon-di-oxide by the process of photosynthesis.
In a chloroplast the stacks of membranous sacs are called?
In a chloroplast, the stacks of membranous sacs are called thylakoid membranes. Grana is the term used to refer to the stacks of thylakoids. It is in this internal part of the chloroplast where photosynthesis occurs.
Chloroplasts make glucose through the process of photosynthesis using light energy, water, and carbon dioxide. This glucose is a form of energy that plants use for growth and other metabolic processes.
Why do cells of plant roots lack chloroplasts?
Chloroplasts hold the nutrients and all that the roots do are suck it up and its stored in the chloroplasts. So chloroplast just hold in the nutrients while the roots suck up the nutrients from the soil so why would there be chloroplasts in a part of the plant that just sucks it up.
Difference between mitochondria and chloroplast?
Mitochondria is an organelle of the cell where as the chloroplast is a kind of plastids.... mitochondria is found in plants and animals both where as chloroplasts are found only in plants... Mitochondria is the power house of cell where cellular respiration takes place and chloroplast is a green pigment especially in leaves that helps it for photosynthesis called chlorophyll. hope its helpful!! ^_^
Nonliving material that makes up the cell walls of plant cells?
The answer is cellulose. Cellulose is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose . It forms the primary structural component of green plants. The primary cell wall of green plants is made primarily of cellulose; the secondary wall contains cellulose with variable amounts of lignin. Lignin and cellulose, considered together, are termed lignocellulose, which (as wood) is argued to be one of the most common biopolymers on Earth (chrysolaminarin is often argued to be the other). Only one group of animals, the tunicates, has the ability to create and use cellulose. Some acetic acid bacteria are also known to synthesize cellulose
What makes chloroplasts green?
Chloroplasts contain a green pigment called chlorophyll. This is what makes plants green
Because they contain the chemical chlorophyll which has a green pigment (pigment = a substance which produces a characteristic colour as a result of the colour (of light) being reflected because of its wavelength - see EM spectrum).
sunlight
What do plants use nitrogen for?
Plants use nitrogen to build important molecules like proteins, nucleic acids, and chlorophyll. Nitrogen is a crucial element for plant growth and development, helping them to thrive and produce fruits and seeds.
