fluid substance that surrounds the grana

thylakoid membrane contains

chlorophyll

enzymes necessary for photosynthesis are found in the ______

stroma

simple diffusion

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

Osmosis

Diffusion of water through a selectively permeable membrane

hypotonic solutions have less solute which means ??

higher water potential

turgor pressure

The pressure that water molecules exert against the cell wall

transport proteins

A transmembrane protein that helps a certain substance or class of closely related substances to cross the membrane.

active transport

molecules that cant diffuse through membranes need the help from pumps, transport protiens.

active transport is an __________ requiring process

energy

sieve cells and sieve tube members

what do sieve cells and tube members do

transport carbs throughout the plant body

epidermal tissue

protection of primary plant body

periderm tissue

cork cells and phelloderm cells provide protection to the secondary plant body

lamina (blade)

The expanded portion of a leaf or petal

petiole

leaf stalk

tendrils

A threadlike, clinging part of a climbing vine.

insectivorous

allows plants to live in soil that may be poor in nitrogen (plants that eat bugs)

Phytomere
