Which statement about chloroplasts is true?

Which statement about chloroplasts is true?

The statement that is true for chloroplasts is that they convert light energy into chemical energy. Explanation: Sun is the energy supply source fir the process of photosynthesis. The pigment present in plants that help to trap the solar energy is the chlorophyll found in the cell organelle chloroplast.

What is a fact about chloroplast?

Interesting Facts about Chloroplasts Simple cells, like those found in algae, may only have one or two chloroplasts. More complex plant cells, however, may contain hundreds. Chloroplasts will sometimes move around within the cell in order to position themselves to where they can best absorb sunlight.

What is chloroplast explain?

A chloroplast is an organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.

Which statement is true of chloroplasts they transport glucose into the cell they are present in animal cells but not in plant cells they convert light energy into chemical energy they convert the energy in glucose into a more usable form?

Chloroplasts are found in plant cells, which undergo a lot of photosynthesis in order to provide energy to the plant. Mitochondria are the organelles that take the glucose to break it down and use the energy to fuel the cell. Therefore, answer B is correct.

Are chloroplasts found in most plant cells?

Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make sugars that feed the cell’s machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating sugars.

Why B2 is paramagnetic in nature while C2 is not?

Answer. B2 has two unpaired electron so it is paramagnetic whereas C2 has only paired electrons so it is diamagnetic.

What is the bond order of F2 2+?

1/2

READ:   Are traits passed on by genes?

Is B2 a bond order?

So the bond order of B2 is equal to 1, which you can get by drawing the molecular orbital diagram and performing the equation Bond Order = . 5 * (# of bonding electrons – # of antibonding electrons). However, when you draw the Lewis structure of B2, you get a triple bond.

How many valence electrons are in B2 −?

6 valence electrons

What is the electron configuration for B2?

The Diatomic Molecules of the Second Period

Molecule Electron Configuration Bond Order
B2 (σ2s)2(σ∗2s)2(π2py,π2pz)2 1
C2 (σ2s)2(σ∗2s)2(π2py,π2pz)4 2
N2 (σ2s)2(σ∗2s)2(π2py,π2pz)4(σ2px)2 3
O2 (σ2s)2(σ∗2s)2(σ2px)2(π2py,π2pz)4(π∗2py,π∗2pz)2 2

How many valence electrons are in an atom of he?

two valence electrons

Why does helium only have two valence electrons?

Explanation: Helium is located in period 1, group 18 of the Periodic Table and has an atomic number equal to 2. As a result, neutral helium will only have 2 electrons surrounding its nucleus. Valence electrons are the electrons located in an atom’s outermost shell.

Which statement about chloroplasts is true?

The statement that is true for chloroplasts is that they convert light energy into chemical energy. Explanation: Sun is the energy supply source fir the process of photosynthesis. The pigment present in plants that help to trap the solar energy is the chlorophyll found in the cell organelle chloroplast.

Do chloroplasts turn glucose into ATP?

When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).

How do chloroplasts convert sunlight into energy?

Plants use energy from the sun in tiny energy factories called chloroplasts. Using chlorophyll in the process called photosynthesis, they convert the sun’s energy into storable form in ordered sugar molecules such as glucose.

How do chloroplasts work with mitochondria?

Chloroplasts and mitochondria do not knowingly work together. However, the glucose and oxygen produced by photosynthesis in the chloroplasts are required by the mitochondria in order to carry out aerobic cellular respiration.

What do mitochondria and chloroplasts have in common?

Even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. These prokaryotic cell characteristics include: an enclosed double membrane, circular DNA, and bacteria-like ribosomes.

Why do plant cells need both mitochondria and chloroplasts?

Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.

Are chloroplasts found in all plant cells?

Chloroplasts are present in the cells of all green tissues of plants and algae. In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

Do all plant cells have mitochondria?

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Once the sugar is made, it is then broken down by the mitochondria to make energy for the cell. Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria.

READ:   What represents a homozygous recessive genotype?

In which cell mitochondria is absent?

Mitochondria is absent in Bacteria and also in Blue-Green algae as well. Mitochondria are seen in eukaryotic cells used for respiration purposes. Bacteria are prokaryotes and they do not have mitochondria.

Where is the mitochondria found in a plant cell?

cytoplasm

What does the mitochondria do in plant cells?

Mitochondria are the “powerhouses” of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They’re responsible for capturing light energy to make sugars in photosynthesis.

What are the functions of Golgi apparatus Class 9?

1)They are involved in synthesis of cell wall,plasma membrane and lysosomes. 2)It produces vacuoles which contain cellular secretions eg:enzymes,protein,cellulose etc. 3)They act as an area for storage,processing and packaging of various cellular secretions.

What is the Golgi apparatus analogy?

Golgi apparatus analogy: the Golgi apparatus is sometimes referred to as the packing plant or the post office of the cell because it receives molecules and makes changes to them then sorts and addresses those molecules for transport to other areas of the cell, just like a post office does with letters and packages.

What is the Golgi apparatus compared to?

The Golgi apparatus’s function is commonly likened to that of a post office because proteins are modified, sorted, and packaged by the Golgi apparatus.

What is the Golgi apparatus similar to in real life?

Analogy: The golgi apparatus can be compared to the buses of a school because the buses take kids from school just like the golgi apparatus transports things out of the cell. Function: Carries proteins throughout the cell.

What is a real life example of a lysosome?

Lysosomes are nicknamed “Cleanup Crews”. Their function within a cell is break down food that the cell can use to destroy older cells. A real-life example of lysosomes in a restaurant is the cleaning staff or busboys.

What is a real life example of a cell?

The real life example is like the brain to a human. It makes protiens for the cell in which amino acids are hooked together to make the proteins. It works as a packaging system. A real life example is the company Fed-Ex that ships and transports things everywhere in the world.

What does a cell represents in a real life?

Answer. Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.

What is the name of powerhouse of cell?

Mitochondria

What is a cell class 8?

The cell is the basic structural and functional unit of life. All living organisms are made up of cells. Cells make tissues, tissues make organs, organs make organ systems and organ systems make a living organism. Thus, the cell is the building block, or the structural unit of the living body.
