Cell membrane - 🧠ANSWER ✔✔Hold cellular components and are mainly

composed of phospholipids, cholesterol, and proteins


Organelles - 🧠ANSWER ✔✔Cellular compartments enclosed by

phospholipids bilateral (membrane bound)

Are located within the cytosol (aqueous intracellular fluid) and help make

up the cytoplasm

Only eukaryotes contain membrane-bound organelles


Nucleoid - 🧠ANSWER ✔✔Where prokaryotes keep their genetic material


Nucleus - 🧠ANSWER ✔✔Primarily functions to protect and house DNA


DNA replication and translation occurs here


Nucleoplasm - 🧠ANSWER ✔✔Cytoplasm of the nucleus


Nuclear envelope - 🧠ANSWER ✔✔Membrane of the nucleus

,Contains two phospholipid bilayers with a perinuclear space in the middle


Nuclear pores - 🧠ANSWER ✔✔Holes in the nuclear envelope that allow

molecules to travel in and out of the nucleus


Nuclear lamina - 🧠ANSWER ✔✔Provides structural support to the nucleus,

as well as regulating DNA and cell division


Nucleolus - 🧠ANSWER ✔✔Dense area that is responsible for making rRNA

and producing ribosomal subunits


Ribosomes - 🧠ANSWER ✔✔Work as small factories that carry out

translation

Composed of ribosomal subunits


Rough er - 🧠ANSWER ✔✔Continuous with the outer membrane of the

nuclear envelope and is "rough" because it has ribosomes embedded in it


Lumen - 🧠ANSWER ✔✔Inside of the rough er


Smooth er - 🧠ANSWER ✔✔Not continuous with other membranes


Main function is to synthesize lipids, produce steroid hormones, and

detoxify cells

,Golgi apparatus - 🧠ANSWER ✔✔Made up of cisternae (flattened sacs) that

modify and package substances


Lysosomes - 🧠ANSWER ✔✔Membrane-bound organelles that break down

substances (through hydrolysis) taken in through endocytosis


Transport vacuoles - 🧠ANSWER ✔✔transport materials between organelles


Food vacuoles - 🧠ANSWER ✔✔temporarily hold endocytosed food and

later fuse with lysosomes


Central vaacuoles - 🧠ANSWER ✔✔Very large in plants and have

specialized membrane called the tonoplast

Function in storage and material breakdown


Storage vacuoles - 🧠ANSWER ✔✔store starches, pigments, and toxic

substances


Contractile vacuoles - 🧠ANSWER ✔✔Found in single-called organisms and

works to actively pump out excess water


Endomembrane system - 🧠ANSWER ✔✔Group of organelles and

membranes that work together to modify, package, and transport proteins

and lipids that are entering or exiting a cell

, Includes the nucleus, rough and smooth ERs, Golgi apparatus, lysosomes,

vacuoles, and cell membrane


Peroxisomes - 🧠ANSWER ✔✔Perform hydrolysis, break down stored fatty

acids, and help with detoxification


Mitochondria - 🧠ANSWER ✔✔Powerhouse of the cell


Produces ATP for energy use through cellular respiration


Chloroplasts - 🧠ANSWER ✔✔Found in plants and some protists


Carry out photosynthesis


Centrosomes - 🧠ANSWER ✔✔Organelles found in animal cells containing

a pair of centrioles


Cytoskeleton - 🧠ANSWER ✔✔Provides structure and function within the

cytoplasm


Microfilaments - 🧠ANSWER ✔✔Smallest structure of the cytoskeleton, and

are composed of a double helix made of two actin filaments


Cyclosis - 🧠ANSWER ✔✔'stirring of the cytoplasm'; organelles and vesicles

travel on microfilament "tracks".
