plasma membrane




  1. a microscopic membrane of lipids and proteins that forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and that regulates the passage of molecules in and out of the cytoplasm. its in both plant and animals

cell wall

-outer layer

-protection

in plants

Big image

cytoplasm

-clear tick jelly like material that found inside the cell membrane

- support and protect organells

- in both plants and animals

Big image

nucleus

-hold DNA

-control cell activity

-in both plants and animals

Big image

nuclear membrane

-surround in nucleus and has a double membrane

-control the movement of material in/ out of the nucleus

-in both plants and animals

Big image

nucleolus

-found inside the cell nucleus

-found in ribosomes

-in both animals and palnts

Big image

centrioles

-made of a cylinder of microtubule pairs

-separate chromosome pairs during mitosis

-found in animals

Big image

chromatin

-complex or macromoleclues found in cells consisting DNA, proteins, and RNA

-package DNA into a smaller volume to fit in the cell

-in both plants and animlas

Big image

ribosomes

-made of RNA and proteins

-synthesizes proteins

-in both palnts and animals

Big image

golgi apparatus

-stacks of flattered sacs

-package and export proteins

-in both plants and animals

Big image

endoplasmic reticulum

-connects to nuclear envelope and cell membrane

-carries materials throught cells

-in both plant and animals

Big image

mitochondria

-inner membrane fold into cristae

-breaks down sugars moleclues to release energy

-in both plants and animals

Big image

chloroplast

-green, oval containing chlorophyll (green pigment)

-release oxygen

-found in plants

Big image

lysosomes

-smalls and round with a single membrane

-digest all cells parts

-found in animlas

Big image

peroxisomes

-small organells that is present in the cytoplasm

-break down long chains of fatty acids

-in both plants and animals

Big image

vacuole

-largest organell in plant cells

-store food, water, metabolic and toxic wastes

-in both plants and animals

Big image

cytoskeleton

-made of microtubules

-move organells within the cells

-in both plants and animals
