Cells

5th Grade ScienceS5L3 – 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 theirfunctions

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).

CELLS

CellsA 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 liketiny building blocks.

Cells do thejobs that keeporganismsalive.

Cells are the smallestpart of a living thing.

Types of Cells

There are two types of cellsAnimal Cell Plant Cell

Do you notice any differences?

Animal Cell

Plant Cell

Compare and Contrast plant and animal cells.

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

NucleusFunction: 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 MembraneFunction: 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
