What kind of cell has no chlorophyll or chloroplasts?

Prokaryote cells have cell walls, but no chloroplast. An example of a prokaryote is bacteria.

Are elaters in bryophytes haploid or diploid?

Both the elaters and the spores inside the spore capsule are haploid.

Can an organism have several chloroplasts?

Yes, certain organisms such as algae and plants can have multiple chloroplasts within their cell. These chloroplasts are the site of photosynthesis and contain chlorophyll, which helps convert light energy into chemical energy for the organism.

What does chlorophyll transfer to other plant molecules?

Chlorophyll transfers energy to other plant molecules such as proteins, which then use this energy to carry out photosynthesis. This energy transfer process is a key step in converting sunlight into chemical energy for the plant's growth and development.

What is the internal membranes found in chloroplast called?

The internal membranes found in chloroplasts are called thylakoid membranes. Thylakoid membranes house the pigments and proteins necessary for the light-dependent reactions of photosynthesis. These membranes are arranged in stacks called grana.

What are some unicellular eukaryotes that contain chloroplasts?

Some unicellular eukaryotes that contain chloroplasts are Chlamydomonas, Euglena, and diatoms. These organisms are capable of photosynthesis due to the presence of chloroplasts, which enables them to produce their own food.

Is chlorophyll a charged particle?

No, chlorophyll is not a charged particle. It is a pigment molecule found in plants and is involved in the process of photosynthesis. Chlorophyll absorbs sunlight and converts it into chemical energy, which is used by the plant to produce glucose.

What does the chloroplast do in a plant cell do?

Chloroplasts are organelles in plant cells responsible for photosynthesis, where sunlight is converted into energy by producing glucose. They contain chlorophyll, a pigment that gives plants their green color and absorbs sunlight for the photosynthetic process. Chloroplasts also play a role in synthesizing and storing various compounds needed for plant growth and development.

What are stacks of disks containing chlorophyll in a chloroplast called?

The stacks of disks containing chlorophyll in a chloroplast are called thylakoids. Thylakoids are membrane-bound compartments where the light-dependent reactions of photosynthesis occur. Multiple thylakoids are usually stacked on top of each other to form grana.

What is difference between charophyta and chlorophyta?

Charophyta is a group of green algae that includes charophyceans, which are the closest algal relatives to land plants, while Chlorophyta is a diverse group of green algae with a wide range of body forms and habitats. Charophytes have complex multicellular structures and reproductive strategies similar to land plants, while chlorophytes tend to be more simple in structure and reproductive processes.

What is the green pigment found within the grana that makes the chloroplasts and the leaves green?

The green pigment found within the grana of chloroplasts is chlorophyll. It is responsible for capturing light energy during photosynthesis.

What are yellow orange pigments in chloroplasts?

Yellow-orange pigments in chloroplasts are known as carotenoids. These pigments help to capture light energy for photosynthesis and also play a role in protecting the chloroplasts from damage caused by excessive light.β-carotene and xanthophylls are examples of carotenoids found in chloroplasts.

What is the fruit of coriander?

The fruit of coriander is called coriander seeds. These seeds are small, round, and have a citrusy, nutty flavor. They are commonly used as a spice in cooking and can be either whole or ground.

What is the function of the cell wall and chloroplast?

The cell wall provides structural support and protection to plant cells, while chloroplasts are the organelles responsible for photosynthesis, converting light energy into chemical energy in the form of glucose.

What foods have the most chlorophyll?

Green leafy vegetables like spinach, kale, and Swiss chard are some of the best sources of chlorophyll. Other foods such as green beans, peas, and parsley also contain high levels of chlorophyll. Algae like spirulina and chlorella are also rich in chlorophyll.

What cell has lots of chloroplasts and photosynthesis?

Plant cells have a large number of chloroplasts which are responsible for carrying out photosynthesis, the process by which they convert sunlight into energy. This process allows plants to produce their own food by utilizing sunlight, water, and carbon dioxide.

Where are chloroplasts located within plant cell?

Chloroplasts are located within the cytoplasm of plant cells, specifically in the mesophyll cells of leaves. They are also found in other green parts of the plant, such as stems and unripe fruits.

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.
