Lesson 2: Cells organelles

Cell Wall

• Outside covering of cell that supports and protects the cell.

Cell Membrane

Selectively permeable- A plant cell allows certain things to come through the cell membrane i.e. water, while blocking

other things from entering.

The Cell membrane PSS.HO.1

Chloroplasts

• Contain Chlorophyll; where photosynthesis occurs.

Endoplasmic Reticulum

• Where proteins are created from DNA

Mitochondria

• Transfers energy from organic compounds to ATP

• ATP – Adenosine Triphosphate– Transfers energy from chemical bonds to

energy absorbing reactions within the cell.

Nucleus

• Contains DNA and manages most functions of the plant

Nuclear Membrane

• Surrounds the nucleus

Vacuole

• Stores enzymes and waste products.

Cytoplasm

• The region of the cell between the membrane and the nucleus.

Surrounds the nucleus

Question #1

Question #2

Extend through the cell membrane exposing it both to the outside and inside of the membrane. This allows the integral proteins to act as transport channels.

Question #3

• Contains the DNA and manages most of the functions of the plant

Question #4

• Has a polar and nonpolar end. The polar end likes water and the nonpolar end hates water.

Question #5

• Are located on both the interior surface and the exterior surface of the cell membrane, they are linked to lipids or other proteins.

Question #6

• Transfers energy from organic compounds to ATP

Question #7

• The region of the cell between the cell membrane and the nucleus

Question #8

• _______ is selectively permeable in order to allow nutrients and other material in.

Question #9

• Supports and protects the cell

Question #10

• Where proteins are created from the DNA

Question #11

• Stores enzymes and waste products

Question #12

• Contain chlorophyll and is the location where photosynthesis occurs.
