Plant Cell

Nucleus

• In plants and animals• Function - “Control center” in ALL cells • Shape of a sphere• Contains cell’s genetic material• Location – floats in the cytoplasm

Nucleolus

• Found inside the nucleus• Responsible for making ribosomes

Endoplasmic Reticulum• Looks like a ribbon• Function – carry proteins and other materials

from one part of the cell to another.• Location – floats throughout the cytoplasm• Smooth – makes lipids (fats), • Rough – contains ribosomes on its surface and

makes proteins to be passed thru the cell, makes cell membranes.

Golgi Body

• Flat pancake-like sacs• Function- “mail room” where protein

molecules are sorted, changed, packaged, and distributed thru the cell and outside the cell.

Ribosomes

• Tiny ball-like structures• Location – surface of endoplasmic reticulum

and free floating in the cytoplasm• Function – factories to produce proteins

Cell Membrane• Description: In plant and animals it is a

Selectively Permeable Membrane• Location - Outer boundary (after the cell wall) • Function - Controls what goes in and out of

the cell.

Cell Wall• Description—In plants only. tough, rigid outer

covering • Location –surrounds the cell membrane of

plants cells.• Function - Protects and supports the plant

Vacuole

• Large water filled sac• Location – floats in cytoplasm• Function – storage areas of cells• Large in plants cells and small in animals cells• Store wastes, food and other materials

needed by the cells.

Cytoplasm• Description—Jelly like Fluid within cell that

contains organelles that is made up of about two-thirds water

• Location - between cell membrane and the nucleus

• Function - helps move things around in cell and where the 1st part of respiration takes place

Lysosome

• Small spheres• Location – floats in cytoplasm• Function – contains digestive enzymes that

break down bacteria and viruses within a cell.

Chloroplast

• Green oval-shaped structures that give plants their green color

• Location – green structure in cytoplasm• Function – capture energy from sun to

produce food for the cell.

Photosynthesis

Photosynthesis• The process of changing light energy to

chemical energy • Energy stored as sugar• Occurs in plants and some algae • Plants need light energy, CO2, and H2O • Takes place in the chloroplasts, using

chlorophyll, the green pigment in plants

Mitochondria

• Kidney-bean shaped organelle• Location - floats in cytoplasm• Function – “Powerhouse” because it changes

energy stored in food compounds into a useful form of food.

Respiration

Respiration• The breakdown of glucose molecules to

release energy • Takes place in all living things• 1st stage takes place in the cytoplasm• 2nd stage takes place in the mitochondria

Cellular Transportation

Active Transport Passive Transport Endo and Exo

Passive Transport

Passive Transport is like sledding down a hill. Moving high to low

does NOT take energy

Active Transport

Active Transport is like running up hill. Moving from Low to High takes

ENERGY!
