GENERAL OBJECTIVES

At the end of this lesson students should : Be cognizant that all organisms are made up from cell. Be cognizant of unspecialized plant and animal cells. Identify cell organelles.

SPECIFIC OBJECTIVES

At the end of this lesson students should be able to :Tell the importance of cells.Draw simple diagram of unspecialized cells in plant and animal. Label and state the functions of each cell components.

The cellThe cell All organisms are made up of simple

basic units called cells.

Most cells are too small to be seen by the naked eye.

Their structure only visible when viewed with a microscope.

The Structure of cellsThe Structure of cells

Organisms, such as bacteria and amoeba are unicellular, consisting

of a single cell.

They are able to carry out all the functions needed to sustain life.

Example respiration, nutrition and Reproduction.

Most plants and animals are multicellular

They have different types of cell organized into tissues and then organs.

The cells are specialized to carry out specific functions.

The Structure of cells The Structure of cells Animal cellAnimal cell Has a irregular shape

Do not usually have vacuoles but if present, they are very small.

Cell membrane surrounding the cell contents.

Plant cell Plant cells has a rectangular shape.

Have all the components of Animal cells and other parts.

Vacuole small vacuole large vacuole

Chloroplast No chloroplast Chloroplast present

Chlorophyll No chlorophyll Chlorophyll present

Specialized Cells In The BodySpecialized Cells In The Body While many cells make up simple body

parts, such as tissues, some complete more complex and specialized tasks.

These specialized cells are specially designed to perform the functions for which they are intended.

Each of these cell types are formed and operate differently, ensuring that the cell can carry out the necessary body function that it is intended to complete. Example red blood cells, white blood cells Example red blood cells, white blood cells and nerve cells. and nerve cells.
