What did you observe in the cork slice?

Discovery of Cells When he looked at a thin slice of cork under his microscope, he was surprised to see what looked like a honeycomb. Hooke made the drawing in Figure below to show what he saw. As you can see, the cork was made up of many tiny units, which Hooke called cells. Cork Cells.

What structure do you see inside the cork cells?

The lenticels are pore-like core cell structures in the cork cell arising from the phellogen/ cork cambium. These structures are what facilitates the exchange or flow of gases between the plant stem and its external environment.

What is the structure of a cork?

The cork structure is compact with a very regular arrangement of the individual cells and without intercellular spaces. The cells are in general hexagonal prisms that are stacked base-to-base in radial rows, and the rows aligned in parallel; in adjacent rows, the prism bases often lay in staggered positions.

What observed cell in thin slices of cork?

Robert Hooke’s microscope. Perhaps his most famous observations were in his study of thin slices of cork, describing the pores, or “cells” he viewed. Hooke had discovered plant cells, or more precisely, Hooke had been viewing the cell walls in cork tissue.

Which organelle did Hooke see when he looked at a thin slice of cork under a microscope?

honeycomb
The microscopes of his day were not very strong, but Hooke was still able to make an important discovery. When he looked at a thin slice of cork under his microscope, he was surprised to see what looked like a honeycomb.

Why does Hooke see cork?

Robert Hooke had discovered the small-scale structure of cork and concluded that the small-scale structure of cork explained its large-scale properties. Cork floats, Hooke reasoned, because air is sealed in the cells.

What is cork slice?

Explanation: There are branches present in trees and when you cut a thin slice from there it is known as cork slice and because of this thin cork slice cells were discovered. Smenevacuundacy and 23 more users found this answer helpful.

What is cork describe its structure and function?

A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin. they are protective in nature. :} they prevent desiccation (loss of water from plant bodies), infection and mechanical injury.

What are the features of cork?

It is light, impermeable to liquids and gases, elastic and compressible, provides thermal and acoustic insulation, it is a fire retardant and highly abrasion-resistant. Furthermore, it is completely biodegradable, renewable and recyclable.

Who examine the thin slice of cork?

Robert Hooke
The first person to observe cells was Robert Hooke. Hooke was an English scientist. He used a compound microscope to look at thin slices of cork. Cork is found in some plants.

Who examined slices of cork?

Answer: Robert Hooke’s microscope. Perhaps his most famous observations were in his study of thin slices of cork, describing the pores, or “cells” he viewed. Hooke had discovered plant cells, or more precisely, Hooke had been viewing the cell walls in cork tissue.

What did biologists use to see inside cells?

light microscope
The light microscope remains a basic tool of cell biologists, with technical improvements allowing the visualization of ever-increasing details of cell structure.

What are the walls of a cork cell made of?

A mature cork cell is a dead cell with cell walls made up of a waxy substance called suberin. This substance is highly impermeable to water and gases.

How are lenticels involved in the Cork cell?

Meanwhile, at much higher magnification levels starting at around 40x, more detail of the individual cells start to become visible, including the separation between the individual cork cells, which is a result of the lenticels. The lenticels are pore-like core cell structures in the cork cell arising from the phellogen/ cork cambium.

What to look for in cork cambium tissue?

The growth and development of the cork cambium tissue vary with the plant species in consideration. It also depends on plant age and conditions of plant growth, as can be seen from various surfaces of bark, which may be fissured, scaly, tessellated, flaking off or smooth. 1. Observe the magnified structure of dead cork cells. 2.

Why are cork cells separated in the microscope?

Many details can be made out of the cork cells layout with this low power magnification. Switching to a higher power magnification say x40, the separation between cells can be observed. This separation is believed to be caused by structures that arise from the cork cambium, known as lenticels.
