By design Science Ch.2 how are cells alike and different
cell membrane
A cell structure that controls which substances can enter or leave the cell.
prokaryotic cell
A cell tht doesn't have nucleus
Eurkaryotic cell
A cell with nucleus
Vacuole
A fulid-filled storgae container
Chloroplasts
A large, green oval shaped organelle where photosynthesis tske place
Diffusion
A movement of particles of liquids, gases, or solids from a region af high concentration to one of lower concentration
Endoplasmic Reticulum/ER
A network of tubes like channels that winds through the cytoplasm
Gogli Apparatus
A organelle that packages the materials for the ER to transport
Organelles
A part of a cell that needs to dobits job to keep it alive
Chlorophyll
A pigment that traps light during photosynthesis
Glycolysis
A process that breaks down glucose molecules
cell respiration
A process that occurs in the cytoplasm and the mitochondria of cells by which the cell uses oxygen to brwakdown sugar into water and carbon dioxide
Photosynthesis
A process that plants make food
Osmosis
A process where water passes through the cell membrane
Cytoplasm
A semi-fluid material thay makes up the inside of cells
Glucose
A simple sugar that is a by-product of photosynthesis
Vesicle
A small sac-like structure that forms when part of the smooth ER buds up
ADP
A special energy molecule that changes light wnergy into chemical energy
ATP
A type of high-energy molecule that powers many cell activities
selectively permeable
Ability of the cell membrane to control what are allowed in and out of the cell
Mitochondria
Are organells that release the energy the cell need to function
Nucleus
Control center of the cell
Active transport
Kind of cell transport that ises energy
Multicellular
More than one cell
Unicellular
One cell
Micrometer
One millionth of a meter
Cell wall
Ridged outer layer that keep the cells inside of a plant cell
Lysosomes
Specialized vesicle that floats freely in the cytoplasm
passive transport
When diffusion, facilitateded diffusion, and osmosis occur without energy
Fermentation
a type of anaerobic respiration that does not require oxygen
facilitated diffusion
a type of passive transport that requiers no energy. Which proteins aid in the passing of a substance through the cell membrane
Abiogenesis
scienntist Alexander Oparin suggested that living cells came from nothing (evolution)
