Cell MembraneCell Membrane

Cell Membrane- forms outer barrier to the cell

Function- provides protection and support for the cell and regulates movement of material into and out of cell

CytoplasmCytoplasm

Cytoplasm- clear thick jelly like substance between the Cell Membrane

Function- allows materials to move within the cell

MitochondriaMitochondria

Mitochondria-oval shaped with a wavy inner membrane

Function- (powerhouse) combines food substances like sugar and oxygen and produces energy and CO2 and H2O.

VacuolesVacuoles

Vacuoles- not always found in an animal cell- substance filled sac in the cytoplasm

Function- vacuoles act as storage for both food and water as well as waste products.

LysosomesLysosomes

Lysosomes- not always found in plant cell- small round structures involved with the digestive activities of the cell.

Function- contain enzymes that break down large food molecules into smaller ones.

Endoplasmic Reticulum (ER)

Endoplasmic Reticulum (ER)

Endoplasmic Reticulum (ER)-clear tubular passageways connected to the nuclear membrane

Function-transportation system of the cell, moves proteins to where they are needed.

RibosomesRibosomes

Ribosomes- very small bodies attached to the inner lining of the ER made primarily of the nucleic acid RNA.

Function- produce the proteins needed by the cell

NucleusNucleus

Nucleus- large oval shaped organelle in the cell

Function- regulates or controls all the activities of the cell

Function- regulates or controls all the activities of the cell

Parts of the NucleusParts of the Nucleus

Nuclear Membrane-very similar to the cell membrane regulates what moves into and out of the nucleus

Chromosomes-rodlike objects that contain all of a cells genetic material

Nucleolus-center within the nucleus believed to be where ribosomes are produced

Organelles Unique to Plants

Organelles Unique to Plants

Cell WallCell Wall

Cell Wall- strong and stiff outer layer of the plant cell. The cell wall is nonliving and is made of cellulose.

Function- protects and supports the cell, it enables trees to grow tall

Large Central VacuoleLarge Central Vacuole

Large Central Vacuole-large water filled sac in plant cells

Function- in plants its main function is to store water, when the vacuole is low on water the cell becomes limp. When many cells become limp the plant will wilt.

Vacuole also store nutrients and waste products

ChloroplastChloroplast

Chloroplast- large green structures that float in the cytoplasm

Function- Chloroplasts contain a green pigment called chlorophyll, which captures energy from sunlight. That energy is then used to produce food. This is called photosynthesis.
