1. palmately-lobed – having lobes radiating from a central point. many-sided, multilateral – having many parts or sides.
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.
Beside above, what is a lobed leaf?
Noun. 1. lobed leaf – a leaf having deeply indented margins. foliage, leaf, leafage – the main organ of photosynthesis and transpiration in higher plants.
Why do leaves have teeth?
Plants in drier regions seem to be better off if they have fewer teeth or are toothless. Another theory, proposed by Taylor Field at Taylor University, holds that leaf teeth serve as a sort of ‘release valve’ that prevents too much sap from collecting in the leaf.
Beside this, what is Pinnately lobed?
Pinnately lobed leaves have the lobes arranged on either side of a central axis like a feather. Palmately lobed leaves have the lobes spreading radially from a point, like fingers on a hand. Leaves divided into individual leaflets. Leaflets are distinguished from leaves in that there is no bud at the base.
What kind of tree has leaves with 5 points?
Why do white blood cells have lobed nuclei?
White Blood Cells
Some have different nuclei based upon what they do. Some have lobed nuclei, or nuclei that appear to be split into multiple parts. This is believed to help the white blood cell to change shape and squeeze through blood vessels faster to go fight infections in the body.

having a lobe or lobes; lobate. Botany. (of a leaf) having lobes or divisions extending less than halfway to the middle of the base.
How do you identify a leaf?
- Determine the leaf type.
- Study the leaf arrangement.
- Identify the leaf shape.
- Analyze the leaf’s blade edges.
- Look at the leaf’s vein patterning.
- Check the leaf’s petiole, the stalk that connects the leaf to the tree.
- Record whether the leaf has a stipule.
- Write down the key physical traits of your leaf.
What are the uses of the tree?
Trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses. In parts of the world, forests are shrinking as trees are cleared to increase the amount of land available for agriculture.
What is a lobed nucleus?
Lobes in a nucleus, aka a multilobed nucleus, is found only in certain immune cells, which have packaged their genetic material (DNA) in multiple spheres instead of one big sphere like in most other cell types. These types of nuclei are called lobular nuclei.
What is lobe in biology?
Lobe. (Science: anatomy) a more or less well defined portion of any organ, especially of the brain, lungs and glands. Lobes are demarcated by fissures, sulci, connective tissue and by their shape.
What are the two main leaf types?
The two main categories are simple leaves and compound leaves. A simple leaf has a single blade on its stalk and the stalk is attached to the plant body. A compound leaf is a leaf stalk that has more than one leaf blade on it, and the multiple leaf blades are called leaflets.
How do you describe the texture of a leaf?
Leaf Size, Shape, Texture
Texture usually refers to the overall size of the leaves so textural sizes are relative to one another. Grasses have narrow, fine textured leaves. Salvias have medium textured leaves. Large Hosta leaves are considered coarse textured.
Is lobed a Scrabble word?
LOBED is a valid scrabble word.
What does a simple leaf look like?
A simple leaf is a single leaf that is 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.
How do you identify a simple and compound leaf?
A simple leaf blade is undivided as shown on the left (though the margins may be toothed or even lobed). The blade of a compound leaf is divided into several leaflets as shown on the right. If there is doubt as to whether you are looking at a leaf or a leaflet, locate the lateral buds.
What is the shape of a leaf called?
Leaf shape can vary considerably. The most common shapes include oval, truncate, elliptical, lancolate, and linear. Leaf tips and bases may also be unique, with names based on their shapes.
What kind of tree do I have?
To identify what kind of tree you have, begin by grabbing a leaf. If you please, snap a picture of the tree’s bark, canopy and any identifying features, such as its fruit, blooms and size. Now you’re ready to begin sleuthing. Go forth with confidence, tree detective!
Why are some leaves lobed?
So, lobed leaves may be selected for under certain environmental conditions. Lobed leaves may have greater hydraulic efficiency. For smaller veins, hydraulic pressure increases as they present an increased resistance to water flow. This places stress on the deliate outer leaf tissues.
What are the parts of a leaf?
Leaves have two main parts: The leaf blade and the Stalk or the petiole.
- The leaf blade: It is also called the lamina. It’s generally broad and flat.
- The petiole: It is the stalk-like structure which connects the leaf blade to the stem. The petiole has tiny tubes, that connect the veins on the leaf blade to the stem.
