Eukaryote and Prokaryote comparison

Used for attachment long filamentous polymeric protein structures located at the surface of bacterial cells. They enable the bacteria to bind to specific receptor structures and thereby to colonise specific surfaces.

Fimbriae

Used for locomotion hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms

Flagella

The living surface membrane of a cell that acts as a selective barrier to the passage of materials into and out of the cell

Plasma membrane

What is the function of plasma membrane

Regulates what can enter or what cannot enter inside a cell

The solute is lower than the normal amount outside -when the concentration of dissolved substances is greater inside the cell than the outside.- this will make a cell swell and burst

Hypotonic

The solute is higher in the outside environment compared to inside the cell -a cell without a cell wall will lose water to the environment- it can shrink the cell

Hypertonic

The plasma membrane is composed of

Phospholipid Bilayer

Passage of Materials

Diffusion Osmosis Facilitated Diffusion Active Transport

In order for other substances to enter the plasma membrane, they need what?

Carrier proteins

The net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration

Diffusion

Passage of water from a higher concentration water to lower concetration of water to a selectively permeable membrane -simply defined as the diffusion of water through a selectively permeable membrane.-

Osmosis

Protein carriers helped move substances from high to low concentration

Facilitated diffusion

Uses ATP or cellular energy in order to move the substances from lower to higher concentration. Substances carried are sodium

Active Transport

Support and protect plant cell while providing passage routes of water and dissolve materials to enter and exit. provides strenght to the entire plant A comparatively rigid supporting wall exterior to the plasma membrane in plants, fungi, prokaryotes, and certain protists.

Cell Wall

A cellular organelle that contains DNA and serves as the control center of the cell

Nucleus

Microtubules

A movement of cytoplasm within the cell

Cytoplasmic streaming

Difference of Mitosis and Meiosis
