All green plant tissues can photosynthesize, but in most plants, but the majority of photosynthesis usually takes place in
the leaves
. The cells in a middle layer of leaf tissue called the mesophyll are the primary site of photosynthesis.
Where does the majority of photosynthesis occur in a plant leaf?
1: Structure of a leaf (cross-section): Photosynthesis takes place in
the mesophyll
. The palisade layer contains most of the chloroplast and principal region in which photosynthesis is carried out.
Where in the plant does the majority of photosynthesis occur quizlet?
The process of photosynthesis mostly occurs
within the mesophyll layer of the leaf
since these cells contain the most chloroplasts.
Does photosynthesis occur in all plant cells?
Photosynthesis
takes place inside plant cells in small objects called chloroplasts
. Chloroplasts contain a green substance called chlorophyll . This absorbs the light energy needed to make photosynthesis happen. Plants and algae can only carry out photosynthesis in the light.
Does photosynthesis only occur in plants?
Photosynthesis is seen in plants, algae and some microbes. So,
plants are not the only ones carrying out photosynthesis
. The basic requirement of photosynthesis is sunlight, water, carbon dioxide and the chlorophyll contained in chloroplasts. Plants fulfil all these requirements hence photosynthesis is seen in plants.
Why are plant leaves green quizlet?
Leaves are green
because of a pigment known as chlorophyll
. The chlorophyll masks the colors of any other pigments in the leaf cells. In the autumn, chlorophyll breaks down revealing other colors present in the leaf.
Why do plants appear green quizlet?
Plants are green because
their cells contain chloroplasts which have the pigment chlorophyll
which absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected causing the plant to look green.
Where does photosynthesis take place quizlet?
Photosynthesis takes place
inside plant cells in small things called chloroplasts
. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll.
In which light photosynthesis is maximum?
Photosynthesis occurs more in blue and red light rays and less, or not at all, in
green light rays
. The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. Green light cannot be absorbed by the plant, and thus cannot be used for photosynthesis.
Why does photosynthesis occur in plant cells?
Green plants use photosynthesis
to create energy from carbon dioxide and sunlight
. This energy, in the form of glucose, is used by the plant to grow and fuel the necessary reproductive activities of the plant. Excess glucose is stored in the leaves, stem and roots of the plant.
Does photosynthesis occur in guard cells?
Photosynthesis takes place primarily in the mesophyll tissue, while epidermal cells lack chloroplasts in most species. Guard cells, which developed from protodermal cells,
do contain photosynthetically active chloroplasts in most
species (Gotow et al.
Do photosynthesis and respiration both occur in plants?
Plants carry out both photosynthesis and cellular respiration
. They make their own food, and then break down those glucose molecules later, generating ATP to power their cellular processes. Fun fact!
Where do photosynthesis takes place?
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.
Do plants get their food from the soil?
Plants are called
producers
because they make – or produce – their own food. Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight.
Why are plants green lab answers?
Plants are green
because they reflect green light, and suck up red and blue light
. The chemical that does this is called chlorophyll. Answer 4: … Chlorophyll is the pigment that comprises chloroplasts, which are the structures or “organelles” responsible for converting the sun's energy into useful energy for a plant.
Why are plant leaves mostly green?
So, plants and their leaves look green
because the “special pair” of chlorophyll molecules uses the red end of the visible light spectrum to power reactions inside each cell
. The unused green light is reflected from the leaf and we see that light.
