Cells Study Flashcards
(40 cards)
Protects and supports the cell
Cell Membrane
Layer made of lipids in cell membrane
Phospholipid Bilayer
Extra protection and support, found in Plant and Bacteria
Cell Wall
Controls cell processes, has DNA
Nucleus
DNA wrapped around histones…
Chromatin
Dense form of DNA, think of spaghetti
Chromosomes
Makes proteins
Ribosomes
Makes lipids for the cell membrane
Smooth ER
Has ribosomes that make proteins
Rough ER
Transports things, made of enzyme stacks
Golgi Body
Garbage, makes things usable and has digestive enzymes
Lysosomes
Stores materials like water, salt, etc.
Vacuole
Use glucose to make energy -> ATP
Mitochondria
Name of energy turning into ATP
Cell Respiration
Use photosynthesis
Chloroplast
Made of protein filaments, maintains cell shape and organelles are secured
Cytoskeleton
Liquid inside the cell
Cytoplasm
ALL cells have these 4 things
Cell membrane, ribosomes, DNA, and cytoplasm
Phospholipid head is…
Polar and Hydrophilic
Phospholipid tail is…
Nonpolar and Hydrophobic
When the membrane only lets certain things in and out
Semipermeable or selectively permeable
Examples of small things that are permeable
O2, CO2
Examples of large things that are impermeable
Glucose, macros
Difference between Passive and Active Transport
Passive: Doesn’t need ATP, high -> low
Active: Needs ATP, low -> high
