Why do plants lack muscles and nerves?

Question

Why don't they need them though. Why have evolved like that

I said why do they LACK

Answer 1

animals and plants are completely different organisms evolved for completely different reasons.
animals have muscles in order to move and circulate blood.
nerves are there to gather information about their surroundings and react to stimuli from the environment.
plants can also react to their environment but their detection mechanisms arent nerves

Answer 2

not muscles but they have mechanisms for movement and force, a Venus flytrap can close on an insect, the mimosa plant folds its leaves if touched and many plants turn themselves or their parts to follow he sun. These acts require senses to be triggered so even without a nervous system there is a method of communication in the organism, an ability to regulate temperatures, sap flows, respiration rates and transpiration rates by use of the guard cells of the stomata. So what are these mechanisms and how do they operate? I don't know but it seems like a very good question to ask

Answer 3

Because the simplest solution to meeting your biological needs at the time that plants evolved didn't require muscles or a mammalian style nervous system. Since plants rely on light to provide their energy, the most efficient way to obtain that is by being largely static - muscles would be entirely redundant for a plant.

Answer 4

first of all no such thing as "evolved" (but thats another story)..
secondly if plants had muslces and nerves they would have been called animals. they lack muscles and nerves as these tissues consume alot of energy. and in order for a plant to produce energy too support all this muscles it would be impossible for it to do anything else like development or reproduction.

plants instead were CREATED containing chlorphell (to produce energy) and a group of tissues known as "cellulose" which give the plant all the support they need !! instead of nerves there are a group of cells knows as xylem and phylum which transport messages and nutrients along the plant.

Answer 5

I believe plants lack a muscles and nerves because unlike us, they depend on osmotic pressure, aka water. If they have enough water in them, they will stand up straight and tall and be able to function normally, however, if they do not have enough water, they wilt and can die from dehydration.

Answer 6

are u a plant no! then why so worried for them? anyhow just kidding they have phytohormones at the place of muscles nd nerves. the ve of der kind nd we of our kind and our children will have of their kind. plants ve dem but the pronounce different from that of humans.
bye
be a man,
let the plants live der independent life.
don't act plantish can as a rational man.

Answer 7

because they're not required for their place in the eco system! Although Venus Fly Traps do move its just an automatic trigger but perhaps as someone said there is some kind of nervous system there to set it off. strange question.

Answer 8

PLANTS LACK MUSCLES AND NERVES BECAUSE GOD DID NOT WANT THEM TO BE A THINKING SPECIES. LOOK WHAT A SPECIES CALLED 'MAN' WITH A WELL-DEFINED MUSCULAR AND NERVOUS SYSTEM HAS DONE TO THIS EARTH?

Answer 9

Plants have vascular tissue, no need for nerves and muscle tissue.

Answer 10

Because they are plants, they don't need to move, so don't need muscles, and have no brain so don't need a nervous system
