In plants, photosynthesis takes place in
chloroplasts
, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
What is photosynthesis in plants?
Photosynthesis is the process by which
plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar
.
What is the site of photosynthesis in some cells?
Chloroplast
, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.
What is the site of photosynthesis in eukaryotic cells?
Organelles, called
plastids
, are the main sites of photosynthesis in eukaryotic cells. Chloroplasts, as well as any other pigment containing cytoplasmic organelles that enables the harvesting and conversion of light and carbon dioxide into food and energy, are plastids.
Is photosynthesis in plant or animal cells?
For example, plant cells contain chloroplasts since they need to perform photosynthesis, but
animal cells do not
.
Do plant cells have nucleus?
Plants are also made up of millions of cells.
Plant cells have a nucleus
, cell membrane, cytoplasm and mitochondria too, but they also contain the following structures: Cell wall – A hard layer outside the cell membrane, containing cellulose to provide strength to the plant.
What are 4 differences between plant and animal cells?
Plant cells have a cell wall, but animals cells do not
. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. … Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
Which leaf structure is the site where most photosynthesis takes place?
The primary cellular structures that ensure photosynthesis takes place are
chloroplasts
, thylakoids and chlorophyll. Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves.
What is the site of photosynthesis short answer?
The chloroplasts in the plants
are the sites of photosynthesis. Plants synthesise organic nutrients with the help of chlorophyll, atmospheric carbon dioxide, water and solar energy. … This process is known as photosynthesis.
Is the main site for photosynthesis?
Answer: The main site of photosynthesis is
grana inside the thylakoids
. Explanation: … Inside these cells, there are presence of cell organelle named as Chloroplasts which contains the photosynthetic pigments, mainly the green pigments named as chlorophyll.
What are some examples of photosynthesis?
An example of photosynthesis is
how plants convert sugar and energy from water, air and sunlight into energy to grow
. The water from the leaves evaporates through the stomata, and filling its place, entering the stomata from the air, is carbon dioxide. Plants need carbon dioxide to make food.
What is the formula of photosynthesis?
The process of photosynthesis is commonly written as:
6CO
2
+ 6H
2
O → C
6
H
12
O
6
+ 6O
2
. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Do plants take in oxygen?
Most folks have learned that plants take up carbon dioxide from the air (to be used in photosynthesis) and produce oxygen (as a by-product of that process), but less well known is that
plants also need oxygen
. … So plants need to breathe — to exchange these gases between the outside and the inside of the organism.
Does photosynthesis occur in algae?
Photosynthesis is the process by which light energy is converted to chemical energy whereby carbon dioxide and water are converted into organic molecules. The
process occurs in almost all algae
, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella.
Which type of cell has no nucleus?
Prokaryotes
are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
Is NADH produced in photosynthesis?
The light-dependent reactions of photosynthesis convert solar energy into chemical energy, producing ATP and NADPH or NADH to temporarily store this energy.
