What if humans carried out photosynthesis?
A few changes you might see:
- we might be green if we used chlorophyll like In plants
- We would weigh more since we would have more sugar and water reserves
- We might have some extra organs on our skin specializes for photosynthesis, like leaves, but for us.
- We would have much less of a need for carbs, but we still might need some protein
What is the basic process of photosynthesis?
- Photosynthesis is a/an _______________ process.
- _______________ colour of light is responsible for photosynthesis in bacteria.
- Which metal is present in both chlorophyll “a” and “b”?
What is needed for photosynthesis to happen?
What are the three things needed for photosynthesis?

- Carbon dioxide concentration. Carbon dioxide is a necessary reagent for the process to occur.
- Amount of chlorophyll. ...

- Temperature. ...
- Minerals and nutrients. ...
What carries out the process of photosynthesis?
The organisms that are able to carry out the process of photosynthesis are plants and algae.
Which part of the plants carries out photosynthesis?
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.
Which leaf carries out more photosynthesis?
Larger leaf size has a broader surface area with more chloroplasts, absorbs more light from the sun and more number of stomata present on the surface of the leaves, which play a crucial role in gaseous exchange during the process of photosynthesis.
Which three organs help a plant carry out photosynthesis?
The plant body is divided into several organs: roots, stems, and leaves. The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy.
What are the structures that transport water from the roots to the cells that carry out photosynthesis?
They also contain vascular structures that transport water from the roots into the cells that carry out photosynthesis. 1. The plant’s vascular tissues—xylem and phloem—transport water to the leaves and carry glucose away from the leaves. Anyone who cares for plants could probably tell you that pouring water directly onto the leaves isn’t ...
Which part of the leaf is responsible for photosynthesis?
Cells in the mesophyll of the leaf have numerous chloroplasts. In leaves, cells in the mesophyll (the tissue between the upper and lower epidermis) are uniquely suited to carry out photosynthesis on a large scale. This is due to their high concentration of chloroplasts, which are the sites of photosynthesis.
What is the role of the stomata in photosynthesis?
They play a central role in photosynthesis, allowing carbon dioxide to enter the leaf and oxygen to exit the leaf. The stomata also facilitate transpiration, the process by which water vapor is released through a plant’s leaves.
What are the cells that allow gases to pass through the leaf?
2. Stomata, regulated by guard cells, allow gases to pass in and out of the leaf. We may not be able to see them with the naked eye, but the leaves of plants contain tons of tiny holes, or pores, called stomata (sing. stoma). They play a central role in photosynthesis, allowing carbon dioxide to enter the leaf and oxygen to exit the leaf.
How do plants absorb water?
Plants absorb water from the soil, using their roots. As you probably already know, water is necessary for photosynthesis, which primarily occurs in the plant’s leaves. You might wonder how the water gets from the roots into the leaves, and the answer is through the plant’s vascular system! Just like the veins and arteries ...
What are the most important parts of a plant?
Leaves, and the structures they contain, play key roles in photosynthesis. When it comes to photosynthesis, the most important parts of the plant are the leaves. Their cells and structures are specialized to take in light and allow for gas exchange with the air around them.
How does water travel through the xylem?
When a plant’s roots absorb water and nutrients from the soil, these materials move up the stem and into the leaves through the xylem. Capillary action—which relies on liquid’s properties of cohesion, surface tension, and adhesion—is what allows water to “defy gravity” as it travels through the xylem and into the leaves.
Why is photosynthesis so important?
without photosynthesis we wouldn’t have food because it converts energy from the sun into chemical energy for the food chains.
Adaptations of the leaf
In most plants photosynthesis happens in the leaves. Leaves have adapted so that photosynthesis takes place efficiently. The table describes some of its adaptations:
Light
A leaf usually has a large surface area, so that it can absorb a lot of light. It's top surface is protected from water loss, disease and weather damage by a waxy cuticle, which does not stop light entering the leaf.
Carbon dioxide
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. Guard cells control the size of the stomata so that the leaf does not lose too much water in hot, windy or dry conditions.
Water
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.
Photosynthesis and respiration in plants
Plant cells respire, just as animal cells do. If they stop respiring, they will die.
Hydrogencarbonate indicator
Hydrogencarbonate indicator can detect increases and decreases in carbon dioxide concentration.
Why is photosynthesis important?
Photosynthesis in the ocean is vital for the marine ecosystem. It sets the whole system in motion. The ocean is healthy and thriving because of photosynthesis. Our atmosphere is also maintained as harmful gases are absorbed through the process in the ocean.
What are the chemicals that are used to make photosynthesis in the ocean?
Here are the common phytoplankton in the ocean: These phytoplanktons contain the one chemical that is crucial for photosynthesis in the ocean which is chlorophyll. It is used to gain sunlight that enters the water.
What are the characteristics of plants?
Plants or algae in the oceans that photosynthesize have specific characteristics. They are special enough to enable adaptation to the harsh condition of the ocean water. The following are the characteristics needed to survive: 1 Waxy Leaves and Stems: The wax property helps them to prevent harmful microbes to enter. It also reduces the amount of water that the plants have to take in. 2 Long Roots: The plants have long roots or bodies. An example is the brown algae, also known as kelp. The length is meant to help the plant reach the surface of the water. It can also act as a support system for the plant. 3 Able to Remove Excess Salt: Some plants are gifted with the ability to get rid of excess salt in their bodies. This ensure that the plant will stay alive. 4 Stays Afloat: The plants need to float nearby the sea water surface. It is the best way to get as much sunlight and carbon dioxide for photosynthesis. 5 Grow in Shallow Sea Floors: Some plants such as the seagrass can only survive in shallow parts of the ocean. They are one of the places where the sunlight can reach them.
What are phytoplankton?
These phytoplanktons contain the one chemical that is crucial for photosynthesis in the ocean which is chlorophyll. It is used to gain sunlight that enters the water. Phytoplanktons will use photosynthesis to keep the every marine creature in the ocean to stay alive.
What is the chemical that helps other organisms to convert light?
The chemical is called as phycobilins . It is mostly found in red algae, cyanobacteria and dinoflagellates. Phycobilins help other organisms to convert the light that chlorophyll cannot handle. It can get quite hard for light to pass through into the ocean water.
What happens if the ocean doesn't have photosynthesis?
As most of them already exist on the surface of the ocean water, organisms will also carry out photosynthesis there. A lack of nutrients will disrupt the process. Without photosynthesis, the whole marine ecosystem will eventually suffers. 2.
Why do marine organisms need phycobilins?
They phycobilins inside the marine organisms make it easier to absorb any light that is present in the water. They will convert it into the red light that cholorophyll can accept. Photosynthesis can finally occur thanks to the help of phycobilins. Also read: Importance of Algae in Ocean.
