Cells

Both alive, have a cell membrane, have DNA, have ribosomes, the ability to divide and reproduce

Prokaryotes lack a nucleus and have a more simple structure, eukaryotes have membrane bound organelles

Can give rise to any type of cell

Can give rise to most types of cell, but not extra-embryonic cells

Can differentiate into limited number of specialised cells

A pathway where haematopoietic stem cells, which are found in the bone marrow of adults, can differentiate into blood cells.

Process of becoming a red blood cell

Mitosis is a process where a single cell divides into two identical daughter cells.

Prophase, metaphase, anaphase, telephase

The cell cycle is a series of events that take place in a cell, as it grows and divides.

Interphase (Gap1, synthesis, Gap2), Mitosis, Cytokinesis

Cons- poorer resolution, lower magnification Pros- colour images, can view living samples

Pros- higher resolving power, higher magnification Cons-black and white images, samples have to be non-living

Magnification is how much larger the image is compared to the original object

Resolution of a microscope is the minimum distance between two objects where they can be viewed as separate entities

Magnification= size of image / size of object

Eyepiece lens x objective lens = total magnification

The study of how cells control gene activity without changing the DNA sequence.

Cells that were multipotent which have been made into pluripotent cells.

Adds structural strength and prevents water and ion movement.
