Is a xylem cell a plant or human cell?
Its part of a plant cell, a tube that carries energy.-----------------A Xylem cell is a plant cell. The xylem is the woody part of the tree. It is all of the cells between the pith in the center out to the cambium. The xylem consists of the sapwood and the heartwood. There is no one cell called a "xylem cell". Any cell in the xylem portion of the tree could be called a xylem cell.The vessels and/or tracheids in the outer few growth rings in the sapwood carries sap or water (with dissolved minerals) up to the leaves. The inner bark cells carry the food made by the leaves down the tree for use and for storage. The ray cells transport the food radially into the tree for growth. Also the rays cells can transport stored food radially outward in times of shortages or special needs. (like repairing damage by weather or disease or insects or animals, etc.)Phloem
How does refraction help a microscope?
Refraction in a microscope helps to bend light rays, allowing the objective lens to focus on a specimen and magnify it. By bending light through the specimen, the microscope can produce a detailed image of small structures that would otherwise be invisible to the naked eye.
How many ultraviolet rays are there?
There are three main types of ultraviolet (UV) rays: UVA, UVB, and UVC. UVA and UVB are the ones that reach the Earth's surface, while UVC is mostly absorbed by the Earth's atmosphere.
Are X-rays and Gamma rays higher frequencies than ultraviolet rays?
Yes, X-rays and gamma rays have higher frequencies than ultraviolet rays.
Do both x rays and gamma rays have higher frequencies than ultraviolet rays?
Both Gamma Rays and X Rays have a much high frequency that Ultraviolet Rays.
What happens to light rays of a microscope when they hit the specimen?
When light rays hit the specimen in a microscope, they can be absorbed, transmitted through, or reflected by the specimen. The interaction between the light and the specimen allows for imaging and visualization of the specimen's details.
What happens to the light rays when they hit the specimen?
When light rays hit a specimen, three things can happen: transmission (light passes through), absorption (light is taken in by the specimen), or reflection (light bounces off the specimen's surface). The way the specimen interacts with light can provide valuable information for scientific analysis or imaging.
What will converge light rays to a single focal point on the specimen?
The condenser-- when answering for a microscope!
How does convex magnify the image of the specimen?
A convex lens magnifies the image of the specimen by bending light rays towards a focal point, creating an enlarged and focused image. This bending of light rays helps to converge the rays to form a magnified virtual image that appears larger than the actual size of the specimen.
What function medullary rays play in trees?
The medullary rays transport substances from the xylem and phloem to the inner and outer parts of the stem.
Is the real image the reverse of the actual specimen?
Yes, a real image is a faithful representation of the actual specimen. It is formed by the convergence of light rays after passing through a lens or a mirror, creating an image that is inverted compared to the actual specimen.
Is a the real image the reverse of the actual specimen?
A real image is not the reverse of the actual specimen. A real image is formed by the convergence of light rays and can be projected onto a screen, while the actual specimen refers to the object itself. The real image is a focused representation of the specimen.
Microscopes produce images by focusing light rays and beams of cells?
Microscopes create images by focusing light rays through a lens system onto a specimen. The specimen interacts with the light, which is then magnified and captured by the microscope to produce an image, allowing for detailed observation of the specimen at a microscopic level.
Will converge light rays to a single focal point on the specimen?
If you want to know what will do this, a lens will, or a curved mirror
When you see a specimen clearly down a microscope it is in?
When you see a specimen clearly down a microscope, it is in focus. Achieving focus involves adjusting the distance between the specimen and the objective lens to ensure that the light rays from the specimen converge at the focal point of the lens. This allows for a sharp image to be formed on the eyepiece or camera sensor, enabling detailed observation and analysis of the specimen.
What effect has the condenser lens on light rays passing through it?
The condenser adjusts the amount of light passing through the specimen.
What is the function for the objectives on a microscope?
The objective lens on a microscope is responsible for magnifying the specimen being observed. It gathers light rays from the specimen and focuses them to produce a magnified image. By changing objectives, you can adjust the level of magnification on the microscope.
