Who named cells and when?
Robert Hooke coined the term "cell" in the mid 1600's. He named them because when he first observed the under a microscope, he was looking at a piece of cork; whose cells are rectangular and reminded him of the cells in a monastery.
Examples of cell specialization?
Cell specialization is the process in which a generic cell develops into a specific type of cell. This happens in response to specific triggers from the body or the cell itself. Three examples of specialized cells are the sperm cell, the fat cell, and the white blood cell.
What is cytophotometry?
The study of cells and chemical compounds within a cell using Cytophotometer: an instrument for examining cells by determining the intensity or wavelengths of light transmitted through them.
What is relative reference?
if you move or copy the formula to another cell, the cells referred formula will changed. Excel adjusts the cell references relative to the new cell in which the formula is pasted. this is called relative referencing.
Is cork produced by a plant or animal?
It's produced by the Cork Oak tree. Workers cut large sections of bark from the tree, taking care not to damage the inner layers. If done correctly, the bark will grow back. Wikipedia has a good article - see related link.
Who named cells after observing cork cell walls in 1665?
Rober Hook named cells as cells.He first observed them.
Is cork a prokaryotic cell?
No, cork is not a prokaryotic cell. Cork is a type of plant tissue called suberin that is composed of dead cells with thick walls. Prokaryotic cells are simple cells found in bacteria and archaea that lack a nucleus and membrane-bound organelles.
Do you believe the cork that Hooke observed could produce new cells Explain.?
No because what he saw was non living cell walls were cells once lived im not sure if the cell walls could produce cells.
Why don't cork cells have cell membranes?
Cork cells do have cell membranes. The cell membrane is a fundamental structure present in all living cells, including cork cells. The unique properties of cork cells that make them suitable for cork production come from the suberin layer outside the cell membrane.
Does a cork cell have a nucleus?
Yes, cork cells are dead at maturity and do not have a nucleus. They are characterized by thick cell walls made of suberin, which is a waxy substance that makes cork cells impermeable to water and gases.
Why did Robert hooke's cork cells appear to be empty?
Robert Hooke's cork cells appeared empty because he was observing dead cell walls. Live cells have contents that can be easily seen under a microscope, but in cork cells, the living material had decayed and left behind only the empty cell walls, making them appear hollow.
Do cork have cell walls?
Yes - cork is made from the bark of trees.
Why are cork cells in a rectangular shape?
Cork cells have a rectangular shape due to the deposition of suberin and lignin in their cell walls, which provides strength and rigidity to the cells. This shape allows cork cells to form a tight, interlocking pattern, making cork a good insulator and providing protection to the plant.
What does a cork cell look like?
A cork cell is typically rectangular or polygonal in shape with thin walls. It is tightly packed and devoid of any living components, such as the nucleus. The walls are lined with a waxy substance called suberin which makes cork cells waterproof and resistant to decay.
What fills the space inside the walls of the cork cells?
what is the name of the cellular structure that surrounds the cork cell
Is cork alive?
A cork cell is a non living cell. These cells form a protective tissue that displaces the stem epidermis as the plant's diameter increases in size. These cells are produce from the living cork cambium. As the cork cambium cells divide, the push older cells towards the outside of the plant where they die and form cork and bark. Will it can The cells of the phellem are called cork cells, they are generated centrifugally, are non-living and have suberized cell walls. The phelloderm consists of cells given off towards the inside of the phellogen, forming the inner part of the periderm.
Which structure was most visible when Anton Van Leeuwenhoek first saw cork cells under a microscope?
The cell walls of the cork were so apparent that it reminded him of the cells in which monks lived, hence the name.
