Is leaf litter excretory in plants? How do plants excrete?

All living things in the world have some common characteristics (e.g., respiration), and excretion is one of them (e.g., human sweating), the way plants excrete is leaf litter, defoliation is the metabolism of plants (except for those plants that do not have real roots, stems, leaves, etc.), and leaf litter will take away excess things from plants (such as:

Inorganic salts), if plants can not discharge those "wastes" in their bodies in time, it will cause an imbalance in the body's internal substances, affect their normal development and even threaten life, so it is normal for you to see some yellowish leaves on the plant occasionally, and some plants in the non-dormant period due to pests and diseases caused by a large amount of defoliation will cause excessive loss of nutrients in the body, it must be timely.

Autumn means the advent of winter, trees need to be dormant for self-protection, and overwintering dormant trees themselves also need nutrients, in order to regulate their own homeostasis, many trees need to fall leaves, reduce the loss of water and nutrients, save energy and wait until the conditions are suitable before re-germination; Some trees such as pines and cypresses can remain evergreen because their leaves are like needle tips and have very little water loss.

The petioles originally grew stiffly on the branches. In autumn, as the temperature drops, several layers of fragile parenchyma cells form at the base of the petioles. Because these cells are easily separated from each other, they are called delamination.

When the separation layer is formed, it breaks if it is blown by a slight breeze, and the leaves fall down.

Deciduous branches are metabolic waste products of trees, which belong to the excretion of plants.

There are two main ways, which are as follows:

1. Since respiration is a common feature of living things, plants also carry out respiration, complete the metabolism in the body, and produce carbon dioxide, water and urea and other wastes.

2. Plant defoliation is an adaptation to the external environment, which takes away some nutrients in addition to the waste in the plant.

Respiration: When plants respirate, they inhale oxygen from the air and then expel carbon dioxide, water, and urea. Transpiration:

When plants evaporate some of the water from the surface layer, waste is excreted. Defoliation: Leaf litter in plants will take away too many metabolites from the body, and it will also lose some nutrients.

How plants excrete waste.

1. Respiration.

Plants can excrete waste products from the body through respiration, it is the hub of metabolism in the plant, affecting the progress of plant life activities, when the plant respires, it will inhale oxygen in the air, and then excrete carbon dioxide, water and urea to complete a metabolism.

2. Transpiration.

Plants can excrete waste products from the stomata through transpiration, and when sunlight hits the leaves of the plant, most of the energy will be converted into heat energy, and the leaves will evaporate part of the surface water to protect themselves in order to regulate physiological functions, and the waste will be discharged.

3. Fallen leaves. Plant defoliation is also a way to discharge waste, this form will not only take away too much metabolites in the plant, but also lose part of the nutrients, and the defoliation phenomenon will generally appear in cold weather, which will greatly reduce the inorganic salts in the plant and affect photosynthesis.

4. Plant species.

Plants mainly include gymnosperms, angiosperms, bryophytes, ferns, algae plants, seed plants, lichen plants, etc., among which gymnosperms include trees, shrubs, vines, etc., and seed plants have vascular tissues in their bodies, which can produce seeds for self-reproduction.

Plants cannot be described in terms of excretion. If the teacher asks, say no. Excretion refers to what animals do, and is one of the links in the digestion of food. Plants cannot eat, that is, there is no excretion. Even insectivorous plants do not have a "excretory" process.

But plants also have the exchange of substances, such as photosynthesis, inhaling carbon dioxide, and emitting exhaust gases - oxygen. Maybe the emission of such exhaust gases can be considered the "excretion" of plants?

Two ways of excretion:

1. Respiration completes metabolism! Produces carbon dioxide and waste such as water and urea!

2. Plant deciduous!

Breath is discharged, such as oxygen.

As for excrement.

Plants do not eat the ...... of other living things

Animals have excrement because when you eat, you eat the food as a whole, it will contain a lot of useless parts, and you will not produce excrement just by eating glucose protein.

You may have seen vegetative people who have been bedridden for a long time in TV series, such as Director Chen Hai in "In the Name of the People", who earned his salary comfortably from the first episode to the last episode.

But what is the life of a vegetative person in reality?

Eating: The first is eating, some vegetative people have a swallowing reflex and can be fed from the mouth, and it is certain that they do not know the taste of food. However, some vegetative people need to eat through a stomach tube.

That is, the family members mix the food and soup every day, beat it into a paste with a juicer, and then inject it directly into the stomach tube through a syringe.

You may not imagine that sometimes a vegetative person eats the same thing as his family, and whatever food his family eats, he can also eat whatever he wants, but it is just beaten into a paste, and the taste can be imagined. Even the food doesn't go through the mouth at all, let alone taste.

Urination: Vegetative people are definitely unable to control urination, and urine will come out when it is basically full. Even some patients have poor control of the bladder muscles, and the urine will keep flowing out, if you use diapers, you may need to change more frequently than the baby, otherwise you will be soaked in the urine and prone to ulceration.

The problem of urination can be solved by a single urinary catheter in most patients. However, if the urethral catheter is inserted for a long time, bacteria may grow on the tube, causing urinary tract infection. For men, you can also use something like a urinal receiver and a urine bag.

This should be discussed in a categorical manner, for example, Populus euphratica uses the holes in the trunk to drain alkali.

Carbon dioxide, oxygen, water, etc., are released through respiration and transpiration.

Metallic elements such as calcium and iron can only be eliminated from plants through leaf litter.

Plants, like humans, also have metabolism, which breaks down organic matter through respiration and achieves excretion.

Plants have stomata on their leaves that excrete carbon dioxide at night.

Plant defoliation, indicating that the organism can excrete waste products produced in the body

So the answer is:

Transpiration, expelled by stomata.

Garbage is discharged through water, just like human sweating.

Deciduous trees can use their fallen leaves to carry away waste.

Sometimes tree roots can also carry away waste.

Plants also generally have a respiration effect.

Transpiration is the process of water loss from the surface of living plants (mainly leaves) to the atmosphere in a state of water vapor, which is different from the evaporation process of physics, transpiration is not only affected by external environmental conditions, but also regulated and controlled by the plant itself, so it is a complex physiological process. The main processes are: moisture in the soil, root hairs, intra-root ducts, intrastem ducts, intraleaf ducts, stomata, and atmosphere.

When plants are young, all surfaces exposed to air can transpire.

So the answer is:
