already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

That is the cuticle.It is made up of cutines.

Is the cell wall present in animal cells?

No. There is just the cell membrane, cytoplasm and the nucleus. No, a Plant cell has a Cell Wall but a Animal has a cell membrane which is the same thing as a plasma membrane

Do all living things have cell walls as outer boundary?

yes ------------------- Actually, that is incorrect. Most plant cells have cell walls as a distinct type of structure. Other cells including bacteria and animal cells have a cell membrane or a plasma membrane as their outer boundary.

Does a leaf have a waxy surface?

Not all leaves have a waxy surface, but some do. Plant cuticles are a protective waxy covering produced only by the epidermal cells of leaves, young shoots and all other aerial plant organs without periderm.

Why is it that onion leaf epidermal cell do not contain choloroplast?

Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors beca (MORE)

Why cell wall is not present in animal cell?

Cell wall is a cellular structure present in plants they are madeup of cellouse and provide rigidity and structural strength to theplants cell while animals need to move around so that animals donot need cellouse cell wall is absent in animals cell in order toallow them to change their shape when ne (MORE)

Are chloroplasts usually present in comsumer cells?

No, consumer organisms (herbivores) only eat the producer plants (green plant material). The consumer only gains energy form the producer things like chloroplasts are just digested and not transferred into the cells of the consumer.

Role of Epidermal hairs in a leaf?

Some are used to create more surface area. Some are used for protection and can be sticky or spiked and also some may be used to keep out a certain amount of light if needed.

Where is the waxy layer on a leaf?

Plants need a large surface area for the up-take of carbon dioxide from the atmosphere for the process of photosynthesis. Unforunately, this increased surface area increases the volume of water lost by transpiration, so a waxy cuticle located on the surface of the leaves reduces excessive water loss (MORE)

Do onoin epidermal cells have cell walls?

Yes. All plants have cell walls, this includes onions. I think it is because it makes the plants themselves stronger but I'm not sure about the explanation, all I know is that plants' cell's have cell walls.

What substances forms the cell membrane and the cell wall of a cell?

Cell membranes are made of phospolipids, or at least that's the major part. Theires a bunch of stuff imbeded in it. They form a double membrane that keeps most things in the cell in and things outside the cell out. Proteins are imbeded in it for both structure and jobs. As for cell walls im not enti (MORE)

How do you prepare onion cells slides?

When I did the lab, I took just a bit of one layer of onion, put it on a slide and dropped a little iodine on it so you can see it better. I put a cover slip over it after that was done. Hope that helps! Firstly take forceps then take out thin onion layer from it .place onion layer on the slide and (MORE)

What is an epidermal cell?

An epidermal cell is a cell that is part of the outer layer of an organism. For example, in humans, skin cells are epidermal. Leaves on plants have epidermal layers on the top and bottom of the leaf.

Why the cell wall present in a plant cell and not in animal cell?

cell wall is present in plants while animals have cell membrane. cell wall mainly helps the plant to remain rigid and fixed. this helps the plants because they are immobile. the cell wall mainly contains cellulose and other substances, which are the main reasons why the trunks and branches of the (MORE)

Why is the waxy cuticle on a leaf?

The waxy cuticle prevents the excessive transpiration from the leaves. However, the transpiration, a term for water evaporation from plants, can still occur through stomata. Without cuticle layer, the water will evaporates through the epidermis much more easily. \nThe transpiration itself is an impo (MORE)

Can a leaf have no waxy surface?

Yes a leaf can not have a waxy surface if it is so adapted. The waxy surface is designed to keep water off, and inside of the leaf. Leaves in the rain forest often have a waxy surface to keep from being constantly saturated in water.

What is cell wall important in leaf cell?

it is important because if there is no cell wall it would be floppy and wilted because it is like not having any bones and it would not have a shape. it is important for it to have a large surface area so it can do more photosynthesis.

What cells are epidermal cells?

epi is a prefix meaning on or above dermal means skin So... epidermal refers to skin cells or may also refer to the outer most plant cells as well.

Is cell wall present in eukaryote?

A eukaryotic cell is simply one which contains organelles and as such may or may not have a cell wall. Some do (such as in plants) and some don't (such as in animals).

What is the outer cell wall of a bacterial cell made of?

the cell wall of gram+ve bacteria contains a large amount of peptiglycan and teichoic acids. the cell wall of gram-ve bacteria contains small amount of peptidoglycan.the outer layer of cell wall contains toxic lipopolysachharide.

What substance forms the cell wall?

The main components of a plant cell wall are cellulose, hemicellulose and pectin. Algal cell walls are usually made of a polysaccharide (such as cellulose) or a glycoprotein. Fungal cell walls are usually made of chitin.

Do the cells that cover the outer part of a leaf cell do its job based on its shape?

The cells on the outside of the leaf form the epidermis. On the bottom in the stomata. It lets carbon dioxide, water, and sunlight in and oxygen and glucose/sugar out. I don't think the shape of the leaf would really make a difference. This is something that I'm not too sure about, but I would say t (MORE)

Why are cell walls and chloroplasts present in plant cells?

For the cell wall, it is present in the plant because it functions is to keep the cell its shape. Example: leaf - it has its shape because it has cell wall. For the chloroplast, it is present in the plant cell because it functions is to trap sunlight for the plant to photosynthesize. Example: leaf (MORE)

What does the cell and wall of a leaf do?

they somewhat protect the leaf. so the does the sell membrane. the endoplasmis relitculum form together with the golgi bodies, then attach to the ribosomes and mitochondria

What is the outer layer of a cell membrane or wall?

Both! The kind of outer layer depends on the type of cell - (animal or plant). A plant cell has a cell wall but the animal cell has a cell membrane. The animal cell does not have a cell wall because, a cell wall would be more hard and "strict." The animal cell needs to be more flexible and "loose." (MORE)

What is present in plant cell wall?

Cellulose is the most notable and prominent component which is present in plant cell walls. The walls also contain types of matrix polysaccharides. One example is pectic polysaccharide.

How do you examine leaf epidermal cell?

Leaf epidermal cells are examined by making peelings of epidermalcells from both sides. Normally these peelings are stained and examined under the compoundmicroscope.

Why is the cell wall not present in animals?

Animals cells use a cell membrane rather than a cell wall. Animals have more active metabolisms than plants do, and therefore they need faster diffusion from cells to circulatory systems, than they would get with cell walls.
