"Gate Keeper," selectively permeable, thin flexible barrier around cell whose main job is to protect cell while allowing interaction
Rigid, everything can go through, (only in Plants)
Jelly like substance that fills cell
Large structure that contains genetic material and controls cell activities
Contains DNA, attached to proteins, thread like structures contain genetic information
Membrane that allows materials to move in and out of nucleus
Assembly of ribosomes begins
Make proteins, proteins assembled, free floating or attached to Rough ER
Smooth Endoplasmic Reticulum
Cell components are assembled and modified, make lipids. Can detoxify and break down glycogen.
Rough Endoplasmic Reticulum
Cell membrane is assembled, makes proteins, studded with ribosomes
Recieves modifies and ships molecules (mostly proteins). Ships in and outside cell.
Sacs filled with enzymes, break down lipids, carbohydrates, and proteins from food into particles. Remove debris/breakdown. Programed cell death "suicide sacs." (Only in Animals)
Giant central one in plants, store materials used by cell like salts, proteins, and carbs in a sac-like structure
Uses energy from the sun to make energy rich food molecules in a process known as photosynthesis. (Only in Plants)
Uses energy in food to make high energy compounds that cell can use to power growth development and movement.
Network of proteins that give cell shape, involved in cell movement (ex. flagella).
Basic units of life 'atoms' of biology. All have Cell Membrane, DNA, Ribosomes (proteins) and Cytoplasm
Simple cells, first form of life on earth, has no complex organelles, very small and always unicellular, have no nucleus, no specialization, only bacteria are this.
Complex, have complex membrane, very large, unicellular or multicellular, have a nucleus, can be highly specialized, every living thing EXCEPT bacteria are this.
Lack cell wall, lack chloroplast, have only small vacuoles, might have cillia or flagella.
Have a cell wall, have chloroplasts, have large central vacuole, do not have cillia or flagella.
process where molecules move from areas of high concentration to low concentration. No energy required.
The diffusion of water through a membrane. No energy required.
Outside membrane, loves water (hydrophile). O
Inside membrane, hates water (hydrophobe). I I
Less concentrated solution (move dilute)
More concentrated solution
Total concentration equal
Does NOT require energy energy, works with concentration gradient (high to low, "move down hill"), uses protein channels, used by glucose, salts and some ions.
Requires energy from cell, allows material to move "uphill," molecular pumps, and membrane foldings
Cells take in molecule
Cell moves molecules out
