AP Biology Unit 2 Cells Review
chloroplasts - ANS -contain chlorophyll which help absorb solar energy
in order to convert carbon dioxide and water into sugars during
photosynthesis
flagella - ANS -a long tail-like structure that aids in cell movement
cilia - ANS -a short hair-like structures that enable movement of cells or
movement of materials outside a cell, utilizes a back-and-forth motion
diffusion - ANS -When a substance moves from an area of higher
concentration to an area of lower concentration. Due to entropy.
osmosis - ANS -The diffusion of water through a selectively permeable
membrane.
passive transport - ANS -Transport of a substance across a cell
membrane by diffusion. Going with a concentration gradient.
active transport - ANS -When a cell gets materials or excretes them by
using its own energy, usually through ATP; going against a concentration
gradient.
, hypertonic - ANS -Describes a solution that has a greater concentration
of total solute.
hypotonic - ANS -Describes a solution that has a lesser concentration of
total solute.
isotonic - ANS -Describes solutions that have an equal concentration of
total solutes.
turgor pressure - ANS -The pressure inside of a cell as a cell pushes itself
against the cell wall.
water potential - ANS -The physical property predicting the direction in
which water will flow, governed by solute concentration and applied
pressure.
fluid mosaic model - ANS -Structural model of the plasma membrane
where molecules are free to move sideways within a lipid bilayer.
channel protein - ANS -A membrane protein, specifically a transport
protein, that has a hydrophilic channel that certain molecules or atomic
ions use as a tunnel.
