Parts of A Cell by Ms Pankhurst

cell wall

pankhurs_jacq — 2013-10-16 01:55:48 UTC

rigid layer of nonliving material that surrounds plant cells

Function: protects and supports cell

Type: found in plant cell

cell membrane

pankhurs_jacq — 2013-10-16 01:57:09 UTC

thin flexible barrier around cell (just inside cell wall or cell border)

Function: controls what enters and leaves cell

Type: found in plant and animal cells

nucleus

pankhurs_jacq — 2013-10-16 02:28:25 UTC

large organelle that is usually near the center of a cell

Function: controls the cells activities

Type: found in all eukaryotes

nuclear membrane

pankhurs_jacq — 2013-10-16 02:29:10 UTC

small, spherical structure within the nucleus that holds in strands of genetic material (DNA)

Function: hold in genetic instructions for the cell to do its job

Type: found in all eukaryotes

cytoplasm

pankhurs_jacq — 2013-10-16 02:30:39 UTC

fluid like material inside the cell membrane

Function: contains organelles, site for chemical reactions, "cell jelly"

Type: found in all cells

mitochondria

pankhurs_jacq — 2013-10-16 02:31:45 UTC

bean shaped organelle that has a folded inner membrane

Function: breaks down food to release energy for use by the cell

Type: found in all eukaryotes

endoplasmic reticulum

pankhurs_jacq — 2013-10-16 02:33:02 UTC

internal membrane system rough- has ribosomes smooth- no ribosomes

Function: assembles parts of cell membranes, modifies proteins

Type: found in eukaryotes

ribosomes

pankhurs_jacq — 2013-10-16 02:35:00 UTC

tiny, round structures either attached to the ER or floating in the cytoplasm

Function: makes proteins

Type: found in ALL eukaryotes and some prokaryotes

Golgi body

pankhurs_jacq — 2013-10-16 02:35:48 UTC

stack of membranes in the cytoplasm

Function: receives proteins and other materials from ER, tells proteins where to go

Type: found in all eukaryotes

chloroplast

pankhurs_jacq — 2013-10-16 02:36:39 UTC

tubular organelle that contains chlorophyll (green color)

Function: uses energy from sunlight to make food through photosynthesis

Type: found in many plant cells

vacuole

pankhurs_jacq — 2013-10-16 02:37:32 UTC

large, spacious sack in cytoplasm

Function: stores materials for cell (water, food, waste)

Type: found in all eukaryotes

plants- one large vacuole

animals- many small vacuoles

lysosome

pankhurs_jacq — 2013-10-16 02:38:38 UTC

small, round sacks in cytoplasm

Function: breaks down large food particles and old or damaged organelles

Type: found in all eukaryotes, very rare in plant cells
