plasma membrane

Eukaryotic cell

the movement of molecules in a fluid or gas from a region of hi concentration to a region of low concentration

It moves molecules across a membrane from a low concentration to a hi concentration.

they are organelles that carry out photosynthesis

phospholipid

Nucleus

the diffusion of water.

the process of taking liquids or large molecules into a cell by engulfing them in a cell membrane

found in plant cells it give protection , support and shape to the cell

- charged phosphate group
- glycerol
-two fatty acid chains

Cytoplasm

the solution has the same concentration of dissolved particles inside the cell as outside the cell.

a type of endocytosis in which the cell membrane engulfs large molecules (like other cells)

cylinder shaped organelles made of short microtubules arranged in a circle - they are part of cell diffusion

First the cell membrane is FLEXIBLE and second the variety of molecules within the membrane look like mosaic tiles.

to supply energy for the cell.

a solution with a higher concentration of dissolved particles

the release of substances out of a cell by fusion of a vesicle with the membrane

membrane bound organelles that contain enzymes - they defend a cell from bacteria and viruses.

allows a cell to maintain HOMEOSTASIS

Two (inner and outer)

has more solutes than the cell

1. the vesicle forms around the material that will be sent out. 2. the vesicle moves to the cell surface and fuses to cell membrane 3. then the contents are released.

chloroplast, central vacuole, cell wall
