Roots Stems Leaves Flowers Fruit and seeds |
|
|
Define Meristem |
An area of active cell division called mitosis |
|
|
Define Apical Meristem |
Found at the tips of shoots and roots to increase lenght |
|
|
Define Lateral Meristem |
Found on the edges of plants to increase width |
|
|
Functions of roots |
Anchor Absorb water and minerals Transport absorbed materials to shoot Store food |
|
|
Two root types |
Tap roots Fibrous roots |
|
|
Define Tap roots |
One main root growing from the radicle eg carrot |
|
|
Define Fiberous roots |
Many equal sized roots arising from stem base eg grass |
|
|
Four Root Zones |
Differentiation Zone Elongation Zone Meristematic Zone Protection Zone |
|
|
Define Meristematic Zone |
Where new cells are produced by mitosis |
|
|
Define Protection Zone |
A root cap that protects the cells as the root pushes through the soil |
|
|
Define Elongation Zone |
Here cells increase in size |
|
|
Define Differentiation Zone |
Here cells develop into 3 different types of tissue |
|
|
Three types of plant tissues |
1. Dermal tissue 2. Ground Tissue 3. Vascular tissue
|
|
What are the four tissue shown |
|
|
|
Functions of the Stem |
1. Support the arial parts of the plant 2. Transport water and minerals from roots to leafs 3. Transport food from leafs to roots 4. Sometimes storage |
|
Name the three plants highlighted |
|
|
Name four parts highlighted |
|
|
|
Functions of Leaves |
1. Photosynthesis 2. Transpiration 3. Gas exchange 4. Sometimes store food |
|
|
Function of the flower |
Sexual reproduction |
|
|
Fuction of Xylem |
Transport water and minerals |
|

|
Define Autotroph |
An Autotrophic organism makes its own food |
|
|
How have root hairs adapted to osmosis |
1. Thin walls 2. A large surface area |
|
What are the three highlighted parts |
|
|
|
What process carries water from the root hairs to the xylem |
Diffusion |
|
|
What two processes carry water up the plant |
Root pressure and transpiration |
|
|
Property of the cuticle |
Water can't pass through the cuticle, the presence of the cuticle helps reduce water loss |
|
|
What is a hormone |
A chemical produced in one part of an organism,and transported to another tissue where it has its effect. |
|
|
Sources of carbon dioxide in a plant |
1. Produced in the leaf during respiration 2. Diffuses from the air in through the stomata |
|
|
Modified root for storage |
Diocot plant e.g. carrot |
|
|
Modified stem for storage |
Tubers e.g. potatoes |
|
|
Modified leaf for storage |
Onion bulb |
