Cell Transport, Photosynthesis and Cellular Respiration

phospholipid bilayer

• the cell membrane is composed of

• contains DNA

• controls reproduction of the cell

• provides long term energy

Function of the cell membrane

• give the cell its shape

• regulate what moves in and out of the cell

• produce energy

• store water

attracted to water

• hydrophilic

• hydrophobic

• osmosis

• hydrogen bonds

organelle that contains DNA and acts as the control center of the cell

• vacuole

• mitochondria

• cell membrane

• nucleus

Diffusion of water across a membrane

• mitosis

• facilitated diffusion

• osmosis

• endocytosis

moves ions and small molecules across the plasma membrane with the help of transport proteins

• osmosis

• hydrophobic

• facilitated diffusion

• diffusion

movement of particles from an area of high concentration to low concentration

• osmosis

• diffusion

• homeostasis

• endocytosis

Passive transport requires energy to move particles across the cell membrane.

• True

• False

Active Transport requires energy to move particles across the cell membrane.

• True

• False

Active Transport includes endocytosis and exocytosis.

• True

• False
