Do your cells belong to you? Defend your response

OR

Why are cells called the "building blocks of life?" IF we did not have cells, do you think we could function with only our organs and skeletal system? DEFEND YOUR RESPONSE WITH EXAMPLES

Cells Quiz- Tuesday, January 29th  Identifying organelles of plant and animal cell - OR
Matching- terms and definition-


IF you were not in class Tuesday, because of the chorus field trip- copy the following definitions down on your Cell Concept Term Sheet-

Cell Concept Term Sheet

Cell- smallest unit and function in a living organism

Cell Membrane- allows materials to enter and leave the cell (acts as the gate keeper)

Nucleus- cell structure that directs all the activities of the cell

Nuclear Membrane- surrounds the nucleus and controls movement of materials into and out of the nucleus

Cytoplasm- living fluid inside the cell membrane

Cell Wall- nonliving layer that surrounds the cell membrane of a plant cell

Chlorplasts- oval-shaped structures that contain(chlorophyll) organic material in green plants that absorbs sunlight for making food

Mitochondria- power house of the cell in the cytoplasm that releases energy from foo

Vacuole- large, round-sac in the cytoplasm of the cell that stores water, food, and other materials

Chromosomes- rod-shaped structures that directs all the activities of a cell and passes on the traits of a cell to new cells

Endoplasmic reticulum-maze of passage ways in which proteins and other materials are passed around in the cell

Ribosome-small circular structure in which proteins are made

Lysosome-round structure containing chemicals that break down large food particles into smaller ones

Chromatin-A complex of nucleic acids (DNA or RNA) and proteins, which condenses to form a chromosome during cell division.

Golgi bodies/complex/apparatus- packages molecules like proteins together
