What is the different of the vascular bundles between root and stem?
In roots, vascular bundles are typically arranged in a central core, forming a solid cylinder, with xylem and phloem usually organized in a star-like pattern. In stems, vascular bundles are arranged in a ring formation, allowing for more efficient transport of nutrients and water. Additionally, in roots, xylem is typically larger than phloem, while in stems, the sizes can be more balanced. This structural difference supports the distinct functions of roots and stems in a plant.
What is an atactostele?
An atactostele is a form of eustele, a central core part of a plant's root and stem system, in which the vascular tissue in the stem exists as scattered bundles.
How can you differentiate between the stem and root of cross section of Angiosperm stems and roots by looking at the slides given?
You can differentiate between the stem and root cross sections of angiosperms by looking at specific characteristics. In stem cross sections, you may observe vascular bundles arranged in a ring, pith in the center, and a well-defined cortex. In contrast, root cross sections typically exhibit a central vascular cylinder surrounded by endodermis, pericycle, and cortex, with no pith present. Additionally, the presence of root hairs can help identify a root cross section.
A monocot is an angiosperm that has?
A monocot is an angiosperm that has seeds with one cotyledon or seed leaf, parallel leaf veins, flower parts in multiples of three, and a fibrous root system. Examples of monocots include grasses, lilies, and orchids.
Do both monocots and dicots have root hairs?
Yes, both monocots and dicots have root hairs. Root hairs are tiny, hair-like structures that extend from the roots of plants and increase the surface area for absorption of water and nutrients from the soil.
How are the vascular bundles arranged in the monocot stem?
In monocot stems, vascular bundles are scattered throughout the ground tissue. They are arranged in a complex pattern, with the xylem positioned towards the center and the phloem towards the periphery. This arrangement provides strength and flexibility to the stem.
What is the difference between the arrangement of vascular tissue in the stems of dicots and monocots?
In young dicot and monocot stems do not increase in thickness. Xylem and phloem are arranged in vascular bundles in the cortex. In older stems and all woody stems, the vascular tissues form a cylinder between the cortex and the pith. The vascular bundles in a monocot are scattered throughout the stem.
How are vascular bundle arranged in dicotyledonous root?
In dicotyledonous roots, vascular bundles are arranged in a distinct pattern called the radial arrangement. The xylem is found in the center of the root, forming a solid core, while the phloem surrounds the xylem in a ring formation. This radial arrangement allows for efficient transport of water and nutrients throughout the root.

What selective advantages might be associated with the differences in the vegetative structure of dicots and monocots?
The vascular system of dicots might be advantageous compared to the ancestral condition because it allows for greater pathways for the resources to flow through both threw larger systems with in the stem and the net like system in the leaves. Additionally, the larger bundling of the vascular tissue in the stem may allow for greater support to withstand the water potential within the vascular system, much like how thicker walls of a balloon could withstand greater volumes of air before popping. The presence of two cotyledons could provide the advantage of having more surface available for immediate photosynthesis where as the monocot has to expend more resources if it wants the same surface area. As far as advantages to number of petals or root systems you've got me stumped.

What is the Single layer of cells that forms a waterproof seal around a roots vascular tissue called?
The single layer of cells that forms a waterproof seal around a root's vascular tissue is called the endodermis. It is a specialized layer of cells that helps regulate the movement of water and nutrients into the central vascular tissue of the root.
A monocot is an angiosperm that has?
A monocot is an angiosperm that has seeds with one cotyledon or seed leaf, parallel leaf veins, flower parts in multiples of three, and a fibrous root system. Examples of monocots include grasses, lilies, and orchids.
Which part of a root transport water and minerals from the roots?
The vascular bundles i.e, xylem and phloem transport all materials and water to different parts of plants.
What type of root do dicots have?
Dicotyledon's type of root is a taproots.
Do both monocots and dicots have root hairs?
Yes, both monocots and dicots have root hairs. Root hairs are tiny, hair-like structures that extend from the roots of plants and increase the surface area for absorption of water and nutrients from the soil.
