have carnivorous plants a photosynthesis system?

Answer 1

Yes, and photosynthesis is the chief source of carbon, just as in other plants. But such plants typically live in bogs where there is a minimum of soil or none at all, and a lack of essential nutrients like phosphorus and nitrogen, which are usually absorbed through the roots. They supplement these essential nutrients by capturing insects.

Answer 2

To put it the most simply - if a carivorous plant did not have some sort of photosynthesis system, it would quite simply not be a plant. It would be something else entirely.

To put it another way - most canivorous plants require NO INSECTS to thrive. In other words, they CAN catch things and absorb their nutrients, but they don't have to. This hints strongly that carnivorous plants are -really- 'eating' their prey in the same sense that animals do. Animals who don't eat die. Carnivorous plants who don't eat just get their nutrients elsewhere.

In fact, 'feeding' a carnivorous plant too much can kill it! Some people like to give their venus fly traps bits of hamburger, for example, and are then mortified to see their plants rot from the high fat content!

Answer 3

Yes!!

Carnivorous Plants use their leaves to intercept sunlight. The light energy is used to reduce carbon dioxide from the air with electrons from water, to make sugars (and other biomass), and a waste product, oxygen, in the process of photosynthesis. Leaves also respire, in a very similar way to animals, by burning their biomass to generate chemical energy. This energy is temporarily stored in the form of ATP (adenosine triphosphate), which acts as an energy currency for metabolism in all living things. As a waste product, respiration produces carbon dioxide.

For a plant to grow, it must photosynthesise more than it respires. If a plant respires more than it photosynthesises, then it will eventually burn up all its available biomass, and die. The potential for plant growth is net photosynthesis. Net photosynthesis is the total gross gain of biomass by photosynthesis, minus the biomass lost by respiration. Understanding carnivory requires a cost-benefit analysis of these factors [13].

In carnivorous plants, the leaf is not just used to photosynthesise, but also as a trap. Changing the leaf shape to make it a better trap generally makes it less efficient at photosynthesis. For example, pitchers have to be held upright, so that only their opercula directly intercept light. The plant also has to expend extra energy on non-photosynthetic structures like glands, hairs, glue and digestive enzymes[14]. The energy source for these things is ATP, so the plant has to respire more of its biomass away to keep up with the demand for energy. Hence, a carnivorous plant will have both decreased photosynthesis and increased respiration, making the potential for growth small, and the cost of carnivory high.

Answer 4

They sure do!
Most carnivorous plants live in poor soil. They trap insects to get minerals and fixed nitrogen that they're not getting from the soil.

Answer 5

good question. and yes, i beleive they do. they use the nutrients from the insects as any other plant would from the soil. but they still need sunlight, and are mostly green, which shows they are photosynthetic. i forget why, it just does. look it up.

Answer 6

at the initiating flora do no longer soak up nutrients from the soil. It receives nutrient contained in the type of mineral through diffusion, ok through lively delivery and water through osmosis through the inspiration hairs.

Answer 7

I think so, they have a green leaf dont they?

Answer 8

yes but they use it to take pictures of their victims
