A&p cell & Transport

Animal and plant ce

TermDefinition
Cell membrane Regulates what enters and exits the cell (selectively-permeable membrane)
Cytoplasm Site of most chemical reactions that occur in the cell Gel-like liquid that all of the other organelles float around in Not an organelle
Nucleus Controls all cellular activity “Control center” of the cell Contains chromosomes
DNA Human-46 chromosomes (23 from mom, 23 from dad) Deoxyribonucleic acid
Sex cells 23 chromosomes Sperm Egg
Goofy you Zygote-fertilized egg-> embryo (2 months) -> fetus (7 months) -> baby
Things in order Atom-> molecule-> cell parts (organelle) -> cell-> tissue -> organ-> organ system -> multicellular organism
Nuclear membrane Determines what enters and exits the nucleus Selectively-permeable Porous membrane of the nucleus
Nucleolus Builds (synthesizes)( to make) ribosomes Found in the Nucleus
Ribosomes Protein synthesis (to make)
Endoplasmic Reticulum (ER) Transport system for materials in the cell
Smooth ER No ribosomes attached to it
Rough ER Has ribosomes attached to it
Mitochondria Produces energy(atp) for the cell Site of respiration The powerhouse of the cell
Oxygen (O2) + glucose(C6H12O6) CO2 + H2O + ATP
Vacuole Stores food, water, and wastes products
Centrioles Only in ANIMAL CELL Help in animal cell division (mitosis) Tube-shaped structures found only in animal cells
Daughter cells “Stretches” the cell until it “splits” into 2 identical daughter cells
Cell wall Rigid(stiff) structure that encloses, supports and protects the cells of plants Made of cellulose
Poly(many) saecharide(sugar) Complex sugar
Mono saecharide Simple sugar Glucose C6H12O6
Chloroplasts Site of photosynthesis Photo=light, synthesis =to make So photosynthesis is to make something (glucose) using light! Contains chlorophyll (pigment)(Absorbs light) & makes plants green
Photosynthesis CO2 +H2O -(sunlight)> C6H12O6 + O2 + H2O vapor
Respiration C6H12O6 + O2 -> CO2+H2O+ATP
Large Central Vacuole Stores food, water, and waste Larger in plants
Prokaryotic No nucleus No membrane-bound organelles Smaller Less complex
Eukaryotic Has a nucleus Has membrane-bound organelles Larger More complex
DIffusion process of molecules moving from an area of high concentration(DENSE) to an area of low concentration (LESS DENSE) without the use of ATP. (Energy)
Does diffusion end? Diffusion slows when molecules are evenly distributed on both sides of the cell membrane
What does cell always want to maintain Dynamic Equilibrium Homeostasis Balance
How does diffusion help a cell? Cells can get important substances . (oxygen, H2O, nutrients) Cells can get rid of wastes. (CO2, H2O, nitrogen)
How does diffusion occur(happen )in a cell? In living cells materials pass through small holes, called pores, in the cell membrane(selectively permeable & control what goes IN and OUT of the cell)
Does diffusion use energy? NO! The cell does NOT use energy during diffusion. Diffusion is also known as Passive Transport .
osmosis Diffusion of water across a cell membrane. No energy required (passive)
Why is water important? Water is needed for dissolving and carrying materials, giving support to plant cells and making up 72% of your body!
What are the 2 main things that made up Cell membrane Lipid and Protein
ACTIVE TRANSPORT The process of molecules moving from an area of LOW concentration (LESS DENSE) to an area of HIGH concentration (DENSE) with the use of ATP! (Energy)
SELECTIVELY PERMEABLE The cell can control what goes in or out of the cell membrane. Also called a Semipermeable Membrane

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
