Cells
The Cell Theory- Three Points
The movement of particles from an area of high concentration to low concentration.
Diffusion
Root pressure and transpiration help move water through this tissue.
Xylem
This tropism is a plant's growth response to gravity.
Gravitropism
ATP is produced in this organelle.
Mitochondria
All living things are composed of one of two types of cells:
Prokaryotic & Eukaryotic
The movement of water across a selectively permeable membrane.
Osmosis
This waxy layer helps prevent water loss from leaves.
Waxy Cuticle
This type of tropism occurs when plants grow in response to light.
Phototropism
Organelles are suspended in this jelly-like substance.
Cytoplasm
Two types of Eukaryotic Cells
Plant and Animal cell
Plant cells become turgid when surrounded by this type of solution.
Hypotonic
These tightly packed cells maximize light absorption.
Palisade Tissue
He proposed that a signal was transmitted from the tip of a plant to lower regions to control growth.
Charles Darwin
This organelle packages and ships proteins.
Golgi Apparatus
Organelle that stores food, water, or wastes
vacuole
A solution with a higher solute concentration than the inside of a cell.
Hypertonic
This tiny opening in a leaf allows gases to enter and leave
Stoma
These hormones promote cell elongation in plant stems.
Auxins
This organelle contains digestive enzymes.
Lysosome
converts solar energy to chemical energy
chloroplast
A cell placed in this solution remains the same size because the concentration inside and outside the cell is equal.
Isotonic
These cells respond to environmental conditions to control gas exchange.
Guard Cells
Plants are able to respond to stimuli from around them. What are these responses called?
tropisms
This organelle forms an internal transport network.
Endoplasmic Reticulum (ER)
