COMPARISON BETWEEN ANIMAL CELL AND PLANT CELL

Plant Cell & Animal Cell

Cell Specialization

Cells are specialised to perform different functions in both plants and animals

Example;

Palisade cells have many chloroplasts for photosynthesis
Root hair cells are long and thin to absorb water from the soil
Red blood cells have hemoglobin which transports oxygen
Sperm cells have a tail to swim to the egg
Multicellular organisms cells that perform the same function are grouped together to form a tissue
Each tissue is therefore made up of cells that are specialised to carry out a particular function.

WATER RELATIONS IN PLANT AND ANIMAL CELLS

WATER RELATIONS IN PLANT AND ANIMAL CELLS
The medium (solution) surrounding cells or organisms is described by the terms hypotonic, hypertonic and isotonic
A solution whose solute concentration is more than that of the cell sap is said to be hypertonic

A cell placed in such a solution loses water to the surroundings by osmosis

A solution whose solute concentration is less than that of the cell sap is said to be hypotonic

A cell placed in such solution gains water from the surroundings by osmosis

A solution which has the same solute concentration as the cell sap is said to be isotonic

Introduction

The cell is the basic unit of an organism
All living organisms are made up of cells
Some organisms are made up of one cell and others are said to be multicellular
Other organisms are made of many cells and are said to be multicellular
Cells are too little to see with the naked eye
They can only be seen with the aid of a microscope

The microscope

The microscope is used to magnify objects
