Cell Structure And Function

Front 1

Cell Wall

Back 1

Structure: Plant, not animal, outer layer, rigid, strong stiff, made of cellulose (molecule and has chain of adams)
Function:*Support (grow tall)
*Protection
*Allows H2O, O2, CO2 to pass into and out of cell

Front 2

Cell/Plasma Membrane

Back 2

Structure: Plant-inside cell wall,
Animal-outer layer; cholesterol, (soft waxy substance)
Selectively permeable
Function:*Support
*Protection
*Controls movement of all materials in/out of cell
*barrier between cell and its environment
*maintains homeostasis (maintaining equality)

Front 3

Cytoplasm

Back 3

Structure:Clear, Thick, jellylike.
Function:It supports and protects organelles.

Front 4

Nucleus

Back 4

Structure: Large, oval.
Function: Controls cell activities.

Front 5

Nuclear Membrane

Back 5

Structure:It surrounds nucleus, selectively permeable.
Function:Controls movement of materials in/out of nucleus.

Front 6

Nucleolus

Back 6

Structure: Little nucleus, contains RNA.
Function: It contains ribosomal RNA that is used in transcription and translation.

Front 7

Vacuole

Back 7

Structure:Round, fluid-filled sac in both plant and animal cells. Plants have few big vacuoles while animals have smaller vacuoles if any.
Function: Stores water, food,waste (plants need to store large amounts of food) can be stored in vacuoles too.

Front 8

Lysosome

Back 8

Structure:Uncommon in plant cells but common in animal cells.
Function: It aids in digestion, including the digestion of old cell parts and breaking down large food molecules in to smaller ones.

Front 9

Mitrochondria

Back 9

Structure: Bean-shaped with inner membranes.
Function: Breaks down sugar molecules into energy.

Front 10

Chloroplast

Back 10

Structure: In plants, not animal. Green, oval usually containing chlorophyll (green pigment)
Function: Uses energy from the sun to make food for the plant (photosynthesis)

Front 11

Golgi Body

Back 11

Structure: A membrane structure found near the nucleus. It is made with many layers that make a sac.
Function: Packages and transports molecules.

Front 12

Smooth and Rough Endoplasmic Reticulum

Back 12

Structure: Both plant/animal. Network of tubes or membrane.
Function: Carries materials through the cell.

Front 13

Ribosomes

Back 13

Structure: Both plant/animal Small bodies free or attached to E.R.
Function: Produce proteins.
