Cells 5 th Grade Science S5L3 – Students will diagram and label parts of various cells

This presentation will address the following Learning goals: Define cells Identify the types of cells Identify the parts of a cells and their functions Define and identify living and nonliving

Living Things We are surrounded by living and non-living things. All animals and plants are living things and biology is the study of these living things. A cat playing with a ball is obviously living. A pigeon flying from tree to tree is also a living thing.

Sometimes it is not so easy to decide. Plants are living things but they do not play with balls or fly. If something is living it will carry out all of the seven activities shown opposite.

In science, living is used to describe anything that is or has ever been alive (dog, flower, seed, road kill, log)

Examples

Nonliving Things Nonliving is used to describe anything that is not now nor has ever been alive (rock, mountain, glass, wristwatch).

Number Write Living or Nonlivng for each picture below.

CELLS

Cells A cell is the basic unit of life. All living organisms (or once living organisms) are composed of one (unicellular) or more (multicellular) cells. Q. What does uni- mean? A. One Q. What does multi- mean? A. Multiple, many or more than one

What is the smallest part of this living thing?

Cells All organisms -living things- are made of cells. These cells are like tiny building blocks. Cells do the jobs that keep organisms alive. Cells are the smallest part of a living thing. Graphic Organizer

Types of Cells

There are two types of cells Animal CellPlant Cell Do you notice any differences?

Animal Cell

Plant Cell

Compare and Contrast plant and animal cells. Animal CellsPlant Cells Cell membrane Cytoplasm Vacuoles Nucleus Cell wall Cell membrane Cytoplasm Vacuoles Chloroplasts Nucleus

Cytoplasm Type of cell found in: ALL cells Function: the cytoplasm is made up of a jelly-like fluid and other structures that surround the nucleus. Location: Within cells

Nucleus Function: The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA, the cell’s hereditary material. Type of cell found in: animal and plant cells Location: The nucleus is surrounded by a membrane in the cytoplasm

Cell Membrane Function: allows materials to enter and leave the cell. Type of cell found in: All Cells Location: outer lining of the cell. It separates the cell from its environment

Chloroplast Function: food producers of the cell. Type of cells Found in: The organelles are only found in plant cells. Animal cells do not have chloroplasts. Location: in the cytoplasm

Cell Wall Function: Support and Protection Type of cells found in: plant cells but not animal cells Location: Outer layer surrounding the cell membrane
