What is the difference between the simple leaves and compound leaf?
The difference primarily between simple and compound leaves is that in simple leaves there is a single leaf blade and depression that do not split the leaf blade, whereas, in compound leaves, the depression is deep such that it splits the leaf blades into leaflets.
What are advantages of a compound leaf vs a simple leaf?
Compound leaves, shown in Figure below have the advantage of spreading out the leaf tissue while minimizing the surface area, effectively reducing wind resistance and water loss by evaporation. Desert plants such as mesquite often have compound leaves for this reason.
What is the difference between a simple leaf and a compound leaf quizlet?
What is the difference between a simple leaf and a compound leaf? Simple leaves have a single blade. Compound leaves have blades divided into leaflets. Sometimes, the leaflets are further divided and result in a doubly compound leaf.
What are simple leaves?
Definition of simple leaf : a leaf whose blade is not divided to the midrib even though lobed — compare compound leaf.
What is the difference between a compound leaf and a whole leafy branch?
Moreover, a compound leaf always bears a bud in its axil (axillary bud) but itself does not arise in the axil of another leaf, whereas a branch does not bear an axillary bud but itself occupies the axillary position of a leaf.
What makes a leaf simple?
A simple leaf is singular and never divided into smaller leaflet units. It is always attached to a twig by its stem or the petiole. The margins, or edges, of the simple leaf can be smooth, jagged, lobed, or parted. Lobed leaves will have gaps between lobes but will never reach the midrib.
Are the stomata open or closed?
Responses of stomata to the environment In general, stomata open by day and close at night. During the day, photosynthesis requires that the leaf mesophyll be exposed to the air to get CO2. At night, the stomata close to avoid losing water when photosynthesis is not occurring.
What is a compound 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.
Which is a compound leaf?
a leaf composed of a number of leaflets on a common stalk, arranged either palmately, as the fingers of a hand, or pinnately, as the leaflets of a fern; the leaflets themselves may be compound.
Which hormone is involved in opening and closing of stomata?
Abscisic acid Is the hormone which causes the opening and closing of stomata..
What are C4 plants?
C4 plants—including maize, sugarcane, and sorghum—avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation. This step takes place in the mesophyll cells that are located close to the stomata where carbon dioxide and oxygen enter the plant.
What is a simple leaf with an example?
Simple leaves are single leaves that do not contain any sub-divided leaflets. In simple terms, simple leaves can not be further divided into any smaller units of leaflets. Examples of Simple leaves are Pear, Maple, Hibiscus, Mango, Guava, Oregano, Black oak and many more.
