Why do plants have lobed leaves?
These leaves tend to be smaller in size (and, therefore, have reduced light absorptive surface area) and tend also to have complex edges and lobes (which enables them to disperse absorbed heat very rapidly).What does a lobed leaf look like?
Lobed leaves have distinct rounded or pointed projections, while unlobed leaves do not. Some lobed leaves are pinnate, meaning the lobes are located along a central axis, while others are palmate, meaning they radiate from a single point. Leaf lobes have their own veins, which connect to the midrib of the leaf.

Definition of compound leaf : a leaf in which the blade is divided to the midrib, forming two or more distinct blades or leaflets on a common axis, the leaflets themselves occasionally being compound — compare palmate, pinnate, simple leaf.
Why upper leaf structure looks glossy for what reason the leaf has this part?
However, the reason that the plants leaves are shinier on top is due to a protective wax call cutin that helps the plant to retain water during transpiration.
Does black oak have lobed leaves?

How many lobes does a maple leaf have?
All maples have leaves divided into three, five, or seven lobes. The lobes on some maples are mere indentations in the leaves, while others have lobes so deeply divided that a single leaf can look like a cluster of individual, thin leaves. Hard maples usually have leaves with moderate indentations.

Are oak leaves pinnate or palmate?
Pinnate and palmate are two main classifications of vein patterns used in tree identification. Pinnate leaf veins extend from the midrib to the edges of the leaf. Pinnate venation is sometimes called feather venation. Alders, beeches, birches, chestnuts, elms and oaks have pinnate venation in their leaves.
What trees have helicopter seeds?

What will happen if you remove the air from these spaces?
If you draw the gases out from the spaces, then the leaves will sink because they become more dense than water. If this leaf disk is placed in a solution with an alternate source of carbon dioxide in the form of bicarbonate ions, then photosynthesis can occur in a sunken leaf disk.
Which organ in the human body has the similar function as that of the stomata in plants?
Heart is the organ in human body which has the similar function as that of the stomata in plants….
How is water lost from a leaf?
When the plant opens its stomata to let in carbon dioxide, water on the surface of the cells of the spongy mesophyll and palisade mesophyll evaporates and diffuses out of the leaf. This process is called transpiration . Water is drawn from the cells in the xylem to replace that which has been lost from the leaves.
