1. Because it does not contain too many light absorbing compounds (for example most of its cells do not contain chlorophyll
2. Because it is very thin, which is giving a good chance some of photons will pass through it, rather then be captured by nontransparent molecules within the epiderm
3. If you watch it under a microscope you can notice, that it is not all that transparent - some trichoms are red (they contain anthocyanins), some other epiderm cells (stomata) are green.
What else can I help you with?
How many layer thick is the epidermis?
Answer: the epidermis of a leaf includes: upper epidermis and lower epidermis but if you are referring to the epidermis of an onion: it is only one layer
What does a leaf stomata do?
It's a pore found in the epidermis of the leaf and stem of a plant, used for gas exchange.
What is amphistomatous?
Amphistomatous describes a certain type of leaf morphology in drought adapted plants. These plants have stomates (the openings in the epidermis which allow CO2 to diffuse into the leaf) on both sides of the leaf.
What is the skin on a leaf called?
The outer layer of a leaf's skin is called the waxy cuticle, or just cuticle. You could also include the next layer, the epidermis layer. Mostly, though, the leaf's skin is called the 'Leaf surface'.
What are the five main functions of a leaf and what is each part's function?
Lower epidermis - outmost tissue on the lower side of the leaf; protects the leafUpper epidermis - outmost tissue on the upper side of the leaf; protects the leafPalisade layer - rows of elongated cells in the upper center of leaf; site of photosynthesisCuticle - waxy layer on the covering the epidermis; holds in moisture, prevents loss of waterStoma - opening between the guard cells; allows for gas exchange and water evaporationGuard cells - surround the stoma; control the opening and closing of the stomaVein - supply support for the leaf; contain the xylem and the phloemSpongy layer - irregular shaped cells in lower center of leaf; absorbs gas & some waterAir space - space in the spongy layer; contain gasesXylem - found in the vein; transports minerals and water from roots to shootsPhloem - found in the vein; transports sugar & other products of photosynthesis from leaves to other parts of the plantChloroplast - cells in the leaves that contain chlorophyll; trap light energy and convert it to chemical energyMesophyll - all of the middle tissue of the leaf
What is the epidermis in a leaf?
The surface of the leaf that you see is the "epidermis".
The cuticle and epidermis of leaves are transparent If they weren't what might be the result?
Imagine an opaque object, sunlight wouldn't pass right? So if the cuticle of leaves and epidermis isn't transparent, sunlight wouldn't pass through the leaf and wouldn't allow plants to have photosynthesis.
What would happen if the cuticle and epidermis of a leaf wasn't transparent?
If the cuticle and epidermis of a leaf were not transparent, it would likely affect the process of photosynthesis. Transparency allows light to pass through to the underlying chlorophyll-containing cells, which is essential for photosynthesis to occur. Without this transparency, the leaf may not be able to efficiently capture sunlight and produce energy.
What best describes a leaf's epidermis?
The epidermis covers the lower and upper sides of the leaf.
How many layer thick is the epidermis?
Answer: the epidermis of a leaf includes: upper epidermis and lower epidermis but if you are referring to the epidermis of an onion: it is only one layer
What is the outermost covering of a leaf?
epidermis is the outermost covering of the leaf
The outer layer of a leaf is?
epidermis
What will happen if you only apply vaseline on the upper epidermis of a leaf?
The leaf would curve to the upper epidermis exposing the lower epidemis
What is the function of upper epidermis in a leaf?
The upper epidermis has several functions. It protects against water loss, regulates gas exchange (there are only a few stomata on the uppermost layer of the leaf) and produces the waxy substance that becomes part of the cuticle. The previous answer to this question implies that leaves have a SPINAL CORD - note, this is not true!
What is the function of the plant upper epidermis?
The upper epidermis is responsible for preventing water loss by evaporation. It does this by having a waxy cuticle on the top of the leaf. The lower epidermis has stomata, which allow gases to enter and leave the leaf as a result of photosynthesis and respiration.
Tiny openings in the epidermis of a leaf?
nick
What is the outer protective layer of a leaf?
Epidermis
