Plants Flashcards
What does roots die
Anchor the plants
Absorb the water
And mineral ion (it has nitrates in it )
What do leaves do
Carry out photosynthesis
How do plays get there energy
From the sun
Equation for photosynthesis
Co2+ h20- c6 h12 06 + 02
Why do plants need water
To make glucose because of the water reacts with carbon dioxide to make glue cose
Why do plants need nitrates
To make protein because of the nitrogen in the nitrates
Why do plants need magnesium
To do photosynthesis
What happen to the leaves if there is no magnesium
It turn yellows
All the organism of a plant
Stem
Leaves
Roots
Flower
What is translocation
Moves dissolved sugars
Give one use of sugars for plant
Respiration
.Glucose makes amino acid and proteins
Glucose can be stored in starch
Glucose makes fat and oils
Glucose makes cellulose
What is cellulose
Used to make cell wall
Palisade cell
Does photosynthesis because they have lot of chlorophyll
Sponge mesophyll do
They have air spaces so they can speed up the diffusion for carbo dioxide to go to the palisade
What does guard cell do
Open and close the stomata so they keep the water in the plant so they can survive
What is the leaf vein
They have pipes called xylem and phloem xylem is to transport the water and phloem takes the glucose way from the plants so they can take to other parts of a plant
Meristem cell
A area that contain stem cells
What is taking cutting
Cutting meristem cells so the thing that has just been cut can grow and make a new plant because of the stem
What do stem cell do in plants
They are found in the meristem
The stem cells are able to produce clones of the plant
What is Multi cellular
Organisms that have a large surface are to the volume ratio so that all substance can be exchanged
Where is gas exchange found in humans
Lungs but the alveoli is where gas exchange takes place they have large surface area most lining thin wall and a good blood supply
What are villi
It is the small intestine and it increases the are to asorb more digested food
How does exchange in fish work
They have a large surface area for gas exchange which are gills . The water is transported to the blood by diffusion.
The gill has a gill filament which give a bigger surface area .lamella coves the filament to increase the surface area.
Leaves main purpose
To absorb energy for photosynthesis
What’s a phloem
Transports sugars around the plant
